c) Low birth weight infants, prematurity, still births, and sudden infant death syndrome (SIDS) have been associated with maternal smoking.
d) Smoking in the presence of children is associated with the development of bronchitis, pneumonia, and middle ear infections
HAZARDS of CARBON MONOXIDE
1. Carbon monoxide is a very dangerous gas because it binds with hemoglobin and ultimately reduces the oxygen supplied to the tissues in the body.
2. Carbon monoxide cannot be seen, smelled or tasted
3. Symptoms of carbon monoxide poisoning include: nausea, vomiting, headache, weakness and unconsciousness

Factors or qualities in an object's design and/or use that contribute to comfort, safety, efficiency and ease of use.
Good body mechanics
Positioning and moving clients to promote safety for the client as well as for health care providers
Needed before attempting to move or position a client. Begin with ROM and progress as long as client tolerates. Include balance, gait and exercise
Proper use of muscles to maintain balance, posture, and body alignment when performing a physical task. Nurses use body mechanics when providing care to clients by lifting, bending, and carrying out the activities of daily living.
Center of gravity
1) it is the center of mass
2) Weight is the quantity of matter acted on by force of gravity
3) To lift an object, the nurse must overcome the weight of the object and know the center of gravity of the object.
4) When the human body is in the upright position, the center of gravity is in the pelvis
5) When an individual moves, the center of gravity shifts
6) The closer the line of gravity is to the center of the base of support, the more stable the individual is.
7) The lower the center of gravity, bend the hips and knees
a. Use the major muscle groups to prevent back strain, and tighten the abdominal muscles to increase support to the back muscles
b. Distribute the weight between the large muscles of the arms and legs to decrease the strain on any one muscle group and avoid strain on smaller muscles.
c. When lifting an object from the floor, flex the hips, knees and back. Get the object to thigh level, keeping the knees bent and the back straightened. Stand up while holding the object as close as possible to the body, bringing the load to the center of gravity to increase stability and decrease back strain.
d. Use assistive devices whenever possible, and seek assistance whenever it is needed.
When pushing or pulling a load
a) Widen the base of support
b) Pull objects toward the center of gravity rather then pushing away
c) If pushing, move the front foot forward, and if pulling, move the rear leg back to promote stability
d) Face the direction of movement when moving a client
e) Use own body as counterweight when pushing or pulling to make the movement easier
f) Sliding rolling and pushing require less energy than lifting and offer less risk for injury
g) Avoid the thoracic spine and bending the back while hips and knees are straight.
Guidelines to prevent injury
1) Plan ahead for activities that require lifting, transfer, or ambulation of client, and ask others to be ready to assist at the planned time
2) Be aware that the safest way to lift a client may be with the use of assistive equipment.
3) Rest between heavy activities to decrease muscle fatigue
4) Maintain good posture and exercise regularly to increase strength in arms, legs, back, and abdominal muscles, so these activities will require less energy.
5) Use smooth movements when lifting and moving clients to prevent injury through sudden or jerky muscle movements.
6) When standing for long periods of time, flex the hip and knee through use of a foot rest. When sitting for long periods of time, keep the knees slightly higher than the hips.
7) Avoid repetitive movements of the hands, wrists, and shoulders. Take a break every 15 to 20 minutes to flex and stretch joints and muscles.
8) Maintain good posture (head and neck in straight line with the pelvis) to avoid neck flexion and hunched shoulders, which can cause impingement of nerves in the neck.
9) Avoid twisting the spine or bending at the waist (flexion) to minimize the risk for injury.
1) Used to prevent regurgitation of tube feedings and aspiration in clients with difficulty swallowing
2) Supine with head of the bed elevated approximately 30 degrees and knees slightly elevated about 15 degrees
1) Used during procedures such as NG tube insertion and suctioning. Also for better chest expansion and ventilation, as well as better dependent drainage after abdominal surgeries
2) Supine with head of bed elevated about 45 degrees, and knees slightly elevated about 15 degrees.
1) Promotes lung expansion by lowering the diaphragm and is used for clients experiencing severe dyspnea
2) Supine with head of bed elevated slightly 90 degrees and knees may or may not be elevated
SUPINE OR DORSAL RECUMBENT
1) Ideal for patients with lower back problems
2) Lies on back with head and shoulders elevated on a pillow. Forearms may be placed on pillows or placed at side. A foot support prevents foot drop and maintains proper alignment.
1) Promotes drainage from the mouth for clients following throat or oral surgery, but inhibits chest expansion
2) Flat on abdomen with head to one side
LATERAL OR SIDE-LYING POSITION
1) This is a good sleeping position, but the client must be turned regularly to prevent development of pressure ulcers on the dependent areas. A 30 degree lateral position is recommended for clients at risk for pressure ulcers.
2) Client lies on side with most of his weight on the dependent hip and shoulder. Arms should be flexed in front of the body. A pillow is placed under his head and neck, the upper arm, and under the leg and thigh to maintain body alignment
SIM'S OR SEMI-PRONE POSITION
1) This is a comfortable sleeping position for many clients, and it promotes oral drainage.
2) Client is on his side halfway between lateral and prone positions. (Weight is on the anterior ileum, humerus and clavicle. Lower arm is behind the client while the upper arm is in front. Both legs are flexed, but the upper leg is flexed at a greater angle than the lower leg at the hip as well as the knee.
1) This position allows for chest expansion and is especially beneficial to clients with CPOD
2) Sits in the bed or at the bedside. Pillow is placed on the over-bed table, which is placed across the client's lap. Client rests his arms on the over-bed table .
1) Used during postural drainage, facilitates venous return
2) Entire bed is tilted with the foot of the bed lower than the head of the bed.
REVERSE TRENDELENBURG POSITION
1) Promotes gastric emptying and prevents esophageal reflux
2) Entire bed is tilted with the foot of the bed lower than the head of the bed.
Mass casualty or intra-facility event that overwhelms or interrupts at least temporarily the normal flow of services of a hospital.
TWO TYPES OF DISASTER
a) INTERNAL EMERGENCIES - loss of electric power, severe damage or casualties within the facility
b) EXTERNAL EMERGENCIES - hurricanes, floods, volcano eruptions, terrorist acts, building collapse, safety and hazardous materials.
Categories of Triage
The principles of triage should be followed in health care institutions involved in a mass casualty event. Categories are separated in relation to their potential for survival, and treatment is allocated accordingly
1. Class I (Emergent Category) - Highest priority is give to clients who have life-threatening injuries but also have a high possibility of survival once they are stabilized
2. Class II (Urgent Category)
SIGNS AND SYMPTOMS: sore throat, fever, muscle aches, severe dyspnea, meningitis, shock
TREATMENT PREVENTION: IV ciprofloxacin (Cipro)
SIGNS AND SYMPTOMS: difficulty swallowing, progressive weakness, nausea, vomiting, and abdominal cramps, difficult breathing

THERAPEUTIC COMMUNICATION TECHNIQUES
1) ACTIVE LISTENING - Shows clients that they have your undivided attention
2) OPEN-ENDED QUESTIONS - Used initially to encourage clients to tell their story in their own way. Ask questions in a language that a client can understand
3) CLARIFYING - Questioning clients about specific details in greater depth or directing them toward relevant parts of the history.
4) SUMMARIZING - Validates the accuracy of the story.
Helps nurses develop a rapport with clients. The techniques encourage a trusting relationship, whereby clients feel comfortable telling their stories. Nurses introduce the purpose of the interview, gather information and then conclude the interview by summarizing the findings.
Components of the health history

2. Light palpation (less than 1 cm) required for most body surfaces.
3. Deeper palpation is used to assess abdominal organs or masses
Part of the hands used for different sensations
1. dorsal surface - most sensitive to temperature
2. ulnar surface and base of fingers - sensitive to vibration
3. fingertips - sensitive to pulsation, position, texture, size and consistency
4.fingers and thumb - used to grab an organ or mass.
Involves tapping body parts with fingers, fists, or small instruments to evaluate size, location, tenderness, and presence or absence of fluid or air in body organs, and to detect any abnormalities
Techniques for percussion
a) Direct percussion - involves striking the body to elicit sounds
b) Indirect percussion - involves placing a hand flatly on the body, as the striking surface for sound production
c) First percussion - used to assess for tenderness over the kidneys, liver and gallbladder.
1. Used to listen to sounds produced by the body. Some sounds are loud enough to be heard unaided, but most sounds require a stethoscope or a Doppler technique.
2. The DIAPHRAGM of the stethoscope is used to listen to high-pitched sounds (normal heart sounds, bowel sounds, breath sounds)
3. The BELL is used to listen to low pitched sounds (abnormal heart sounds, bruit). The bell should be placed lightly on the body part being examined.
A written summary of the impression of the client's overall health. The nurse gathers this information from the first encounter with the client and continues to make observations throughout the assessment process.
a) Physical appearance
b) Body structure
e) Vital signs
Measurement of the body's most basic functions. Provide health care staff with information that they need. In most facilities, pain and oxygen saturation are also considered vital signs and may also be measured depending on the reason the client needs health.
1) Reflects balance between heat produced and heat lost.
2) Disease or trauma of the hypothalamus or spinal cord will alter temperature control.
3) The rectum, tympanic membrane and urinary bladder are core temperature measurement sites
Measurement of heart rate and rhythm. Pulse corresponds to the bounding of blood flowing through various points in the circulatory system.
PARASYMPATHETIC NS - lowers the heart rate
SYMPATHETIC NS - raises the heart rate
Body's mechanism for exchanging oxygen and carbon dioxide between the atmosphere and the cells of the body which is accomplished through breathing and recorded as the number of breaths per minute
Reflects the force the blood exerts against the walls of the arteries during contraction (systole) and relaxation (diastole) of the heart.
SYSTOLIC - occurs during the VENTRICULAR SYSTOLE of the heart, when ventricles force blood into the aorta, and represents the maximum amount of pressure exerted on the arteries.
DIASTOLIC - occurs during VENTRICULAR DIASTOLE of the heart, when the ventricles relax and exert minimal pressure against arterial walls, and represents the minimum amount of pressure exerted on the arteries.
1) Oral - 96.8 to 100.4 F (36 to 38 C). Average is 98.6 F (37 C)
2) Rectal - 0.9 F (0.5 C) higher than oral temperature
3) Axillary and Tympanic - usually 0.9 F (0.5 C) lower than oral temperatures
4) Temporal are close to rectal, but they are nearly 1 F (0.5 C) higher than oral and 2 F (1 C) higher than axillary temperatures.
Heat production of the body
a) increases in basal metabolic rate,
b) muscle activity
c) thyroxine output
d) sympathetic stimulation (increases heat production)
Heat loss from the body
a) Conduction - Transfer of heat from body to another surface (body immersed in cold water)
b) Convection - Dispersion of heat by air currents (wind blowing across exposes skin)
c) Evaporation - Dispersion of heat through water vapor (sweating and diaphoresis)
d) Radiation - Transfer of heat from one object to another object without contact between them (heat loss from the body to a cold room)
Temperature of newborns, older adults and hormonal changes
1. Newborns have a large surface-to-mass ratio; therefore they lose heat rapidly to the environment. Newborn Temperatures should be at 97.7 F and 99.5 F (36.5 C - 37.5 C)
2. Older adults loss of subcutaneous fat results in lower body temperatures. Their average temperature is 96.8 F (36 C). They are most likely to be affected by extreme environmental changes (heat stroke, hypothermia). It takes long for body temperature to register due to changes in temperature regulation.
3. Temperature rises with ovulation and menses. With menopause, body temperature may increase by up to 4 C (7.2 F)
Temperature: Exercise, illness and food or fluid intake
a) Exercise and dehydration can lead to hyperthermia
b) Illness and injury associated with inflammation can elevate temperature.
c) Food or fluid and SMOKING can interfere with accurate temperature readings. Wait for 20 to 30 minutes before measuring temperature.
Oral temperature technique
a) Please under the tongue in the posterior sublingual pocket lateral to the center of the lower jaw
b) Hold until sound is heard. If mercury, hold for 3 minutes
c) DO not use glass, mercury filled device for small children or patients who are confused.
d) AGE specific - preferred method for children 4 years old and older
e) May not be appropriate for clients who breath through their mouth or have trauma to face or mouth.
Rectal temperature technique
1. Provide privacy
2. Assist client to SIM'S POSITION with upper leg flexed.
3. Ask client to breath slowly, relax when placing a lubricated thermometer (with a rectal probe) to the anus in the direction of the umbilicus (1 and 1/2 inch for the adult or 3.5 cm) . With resistance, remove immediately.
4. Do not use in clients with bleeding disorders or have rectal disorders.
5. Age specific. More accurate that axillary. Do NOT USE FOR INFANTS 3 months or younger. Use axillary temperature initially
6. Rectal site is used as a second measurement if temperature is above 99 F or 37.2 C
7. Stool in rectum can cause inaccurate readings
Tympanic temperature technique
1) Pull the ear up and back for adult. Pull ear down and back for child younger than 3 years old
2) Place thermometer snugly in the outer ear canal.
3) Do not use for infants 3 months or younger. Axillary is preferred.
4) Excess earwax can affect accuracy of reading
American Academy of Pediatrics recommend this use for infants 3 months old or younger (inaccurate reading)
Complications on Temperature
a) Fever is not harmful unless it exceeds 102.2 F or 39 C
b) Hyperthermia is abnormally elevated temperature
c) Hypothermia is below 35 C or 95 F.
Interventions for Hyperthermia (more than 102 F)

3. Administer antibiotics if prescribed, only after obtaining specimens for blood culture
4. Provide fluids and rest
5. Provide antipyretic, Aspirin, acetaminophen (Tylenol), ibuprofen (Advil).
6. Aspirin is not recommended for children and adolescents ho may have a viral illness (influenza, chickenpox) because of the risk of REYE'S SYNDROME.
7. Pediatric antipyretic dosage depends on weight.
8. Prevent shivering as this increases energy demand.
9. Offer blankets during chills and remove then when patient feels warm. Cooling blanket may be offered.
10. Provide oral hygiene, dry clothing and linens
11. Keep head covered.
12 Maintain environment at 70 to 80 F or 21 and 27 C
Interventions for Hypothermia (below 95 F)
a) Provide warm environmental temperature, heated humidified oxygen, warming blanket, warmed IV fluids
b) Provide cardiac monitoring
c) Have emergency resuscitation equipment on standby
Physiology of the PULSEE
1. Rate - number of times per minute pulse is heard or felt
2. Rhythm - regularity at which each impulse is felt. A premature or late heartbeat can result in an irregular interval in which impulses are felt or heart and can indicate abnormal electrical activity of the heart.
3. Strength (amplitude) - Should be the same from beat to beat and can be graded on a scale from 0 to 4.
Amplitude (strength) scale of the PULSE
0 = absent, unable to palpate
1+ = diminished, weaker than expected
2+ = brisk, expected
3+ = increased
4+ = full volume, bounding
Abnormal pulse rates
1. Tachycardia - rate above 100 / min
2. Bradycardia - rate below 60 / min
3. Dysrhythmias - irregular heart rhythm noted as irregular RADIAL pulse
4. PULSE DEFICIT - apical rate faster than the radial rate. With dysrhythmias, heart rate may contract ineffectively, resulting in a beat heard with the APICAL SITE WITH NOT PULSATION felt at the radial pulse point
Pulse Rates and Age
a) Infants - 120 to 160 / minute. Gradually decreases as child grows older.
b) Average pulse for a 12 to 14 is 80 to 90 / min.
c) Older adults may be weak due to poor circulation; more difficult to palpate
FACTORS LEADING TO TACHYCARDIA
1. Exercise and Fever
2. Medication - epinephrine, levothyroxine (Synthroid), beta2 - andrenergic agonists (albuterol [Proventil])
3. Change positions from lying to sitting or standing
4. Acute pain
6. Anemia, hypoxemia
7. Stress, anxiety and fear
8. Hypovolemia, shock and
FACTORS LEADING TO BRADYCARDIA
1. Long term physical fitness
3. Medications - Digoxin (Lanoxin), beta-blockers (propranolol [Inderal]), calcium channel blockers (verapamil [Calan])
Location of the RADIAL PULSE
Located on the thumb-side of the forearm of the wrist.
a) Place index and middle finger of one hand gently but firmly over the pulse. Assess pulsation for rate, rhythm, amplitude and quality.
b) If regular, count 30 seconds and multiply by 2. If irregular count for a full minute, then compare with Apical pulse
Location of APICAL PULSE
1) Fifth intercostal space at the left midclavicular line. Use this SITE for assessing heart rate of INFANT, RAPID RATES (FASTER THAN 100/min), irregular rhythms, and rates prior to the administration of cardiac medication.
2) Place stethoscope on the chest at the fifth intercostal space at the left midclavicular line. Always count an apical pulse for 1 minute.
RESPIRATION: Physiologic Responses
Chemoreceptors in the carotid arteries and the aorta primarily monitor Carbon Dioxide (CO2) levels of the blood. If Carbon Dioxide rises, the respiratory rate rids the body of excess CO2. For clients with COPD, a low oxygen level becomes the primary respiratory drive.
Process of respiration
a. VENTILATION - exchange of Oxygen and carbon dioxide in the lungs. Measure ventilation with the respiratory rate, rhythm, and depth
b. DIFFUSION - exchange of Oxygen and Carbon Dioxide between the alveoli and the red blood cells. Measure diffusion with pulse oximetry.
c. PERFUSION - Flow of blood to and from the pulmonary capillaries. Measure perfusion with pulse oximetry.
ACCURATE ASSESSMENT OF RESPIRATION
Involves observing the rate, the depth and rhythm of chest wall movement during inspiration and expiration. DO NOT INFORM CLIENT that you are measuring respirations.
a) Rate - full inspirations and expirations in 1 minute. Observe number of times chest rises and falls. Expected range for adults is 12 to 20 breathes / min.
b) Depth - chest wall expansion with each breath. Altered breaths are deep or shallow.
c) Rhythm - breathing intervals. A regular rhythm with an occasional sigh is expected in adults
Noninvasive, indirect measurement of the oxygen saturation (SaO2) of the blood. Range is 95% to 100% although some acceptable levels are at 91% to 100%. Some illness states may even allow for SaO2 at 85% to 89%. Less than 85% is not normal.
FACTORS OF RESPIRATION
1. Age: decreases with age. Newborns have rates of 30 to 60 / minute. School age children have rates of 20 to 30 / minute.
2. Gender: Men are diaphragmatic breathers and abdominal movements are more noticeable.
Women use more thoracic muscles, chest muscle movements are more pronounced when they breathe.
3. PAIN in the chest wall: May decrease depth of respiration. At the onset of ACUTE pain, respiration rate increases but stabilizes over time.
4. ANXIETY - increases rate and depth of respiration
5. SMOKING - causes resting rate of respiration to increase.
6. BODY POSITION - upright positions allow chest wall to expand more fully.
7. Medications such as opioid, sedatives, bronchodilators, and general anesthetics decrease the respiratory rate and depth. Respiratory depression can be a serious adverse effect. Amphetamines and cocaine increase rate and depth.
8. Neurological injury to the brainstem decreases respiratory rate and rhythm.
9. Illnesses affecting the shape of the chest wall, changing the patency of passages, impairing muscle function, and diminish respiratory effort. The use of accessory muscles and respiratory rate increases.
10. Impaired oxygen-carrying capacity of the blood that occurs with anemia or at high altitudes results in increases in the respiratory rate and alterations in rhythm to compensate.
Count a regular rate for 30 seconds and multiply by 2. Count the rate for 1 minute if irregular, faster than 20 / min or slower than 12 / min. Note depth (shallow, normal or deep) and rhythm (regular or irregular)
Complications of Respiratory Intervention
Hypoxemia - SaO2 below 90%
1. confirm sensor probe is working
2. correlate pulse rate on the oximeter with radial or apical pulse
3. confirm O2 delivery system is functioning and client is receiving required O2.
4. Place client on Fowler or semi-Fowler for ventilation
5. Encourage deep breathing.
6. Suction if needed and as ordered
7. Assess for hypoxemia, tachypnea, tachycardia, restlessness, anxiety, cyanosis
9. check for hyperthermia
10. assess vital signs, stay with patient to decrease anxiety
BLOOD PRESSURE: Physiological responses
The principal determinants of blood pressure are CARDIAC OUTPUT (CO) and SYSTEMIC VASCULAR RESISTANCE (SVR)
BP = CO x SVR
CARDIAC OUTPUT is determined by:
1. Hear rate
3. Blood Volume
4. Venous Return
* Increase in any of these, increase CO and BP
*Decrease in any of these, decrease CO and BP
SYSTEMIC VASCULAR RESISTANCE
Systemic peripheral vascular resistance (SVR) is determined by the AMOUNT OF CONSTRICTION OR DILATION OF THE ARTERIES
* Increase in SVR, increase BP
* Decrease in SVR, decrease BP
Blood Pressure Classification
Systolic = SBP
Diastolic = DBP
1.Normal is less than 120 (systolic) and less than 80 (diastolic)
2. PREHYPERTENSION is 120-139 (systolic) and 80 to 89 (diastolic)
3. STAGE 1 HYPERTENSION is 140-159 (systolic) and 90 to 99 (diastolic)
4. STAGE 2 HYPERTENSION is more than 160 (systolic) and more than 100 (diastolic)
When is a diagnosis of hypertension done?
A diagnosis of hypertension is made if the readings are elevated on at least three separate occasions.
A BP that is below the normal (systolic is less than 90 mm Hg) and can be a result of fluid depletion, heart failure or vasodilation
POSTURAL [ORTHOSTATIC] HYPOTENSION
A BP that falls when a client changes position from lying to sitting or standing. The client is experiencing orthostatic hypotension if the SBP decreases more than 20 mmHg and the DPH decreases more than 10 mmHg with a 10% to 20% increase in heart rate. It may result from various causes
1. peripheral vasodilation
2. medication side effects
3. fluid depletion
5. prolonged bed rest.
BLOOD PRESSURE AND AGE
a) Infants have a low BP that gradually increases with age
b) Older children and teenagers vary BP based on body size. Larger children have higher BP
c) Adult BP tends to increase with age
d) Older adults may have a slightly elevated SBP due to decreased elasticity of blood vessels.
Other FACTORS that AFFECT BLOOD PRESSUR
1. Circadian rhythm - BP usually lowest in the early morning hour and peak during the later part of the afternoon or evening.
2. Stress associated with fear, emotional strain, and ACUTE PAIN can increase BP.
3. Ethnicity - African Americans have a higher incidence of hypertension in general and at earlier ages.
4. GENDER - adolescent to middle-age men have higher BP's than their female counterparts. Postmenopausal women have higher BP's than their male counterpart.
5. Medications such as opiates, antihypertensive, and cardiac medication can lower BP. Cocaine, smoking, cold medications, oral contraceptives, and antidepressants can raise BP.
6. Exercise can decrease BP; obesity can increase BP
Equipment for Blood Pressure assessment
Sphygmomanometer with a pressure manometer (aneroid or mercury) and an appropriately sized cuff. The width of the cuff should be more than 40% of the arm circumference at the point where the cuff is wrapped. The bladder (inside the cuff) should surround 80% of the arm circumference of an adult and the whole arm for a child. Cuffs that are too large give a false low reading and cuffs that are too small give a falsely high reading.
Procedures to assess the Blood Pressure using the Ausculatory Method. Client instructions
1. Not smoke or drink any caffeine for 30 minutes prior to measurement
2. Rest for 5 minutes before measurement
3. Sit in a chair, with the feet flat on the floor, the back and arm supported and the arm at heart level.
Procedures to assess the Blood Pressure using the Ausculatory Method. What the nurse should do?
1. Use properly calibrated and validated instruments
2. Use appropriate cuff size
3. Not measure BP in an arm with an IV infusion in progress or on the side where a mastectomy was performed or an arteriovenous shunt or fistula is present.
4. Average 2 or more readings, taken at least 2 minutes apart. If they differ more than 5 mmHg, obtain additional readings and average them.
5. After initial reading, measure BP with client standing
Procedures to assess the Blood Pressure using the Ausculatory Method. Step by Step
1. Apply cuff 2 cm above the antecubital space with the brachial artery in line with the marking on the cuff.
2. Use lower extremity if the brachial artery is not accessible
3. Estimate systolic pressure by palpating the radial pulse and inflating the cuff until the pulse disappears. Inflate the cuff another 30 mmHg and slowly release the pressure to note when the pulse is palpable again (estimated systolic pressure)
4. Deflate the cuff and wait 1 minute
5. Position stethoscope over the brachial artery
6. Close pressure bulb by turning bulb clockwise until tight.
7. Quickly inflate cuff to 30 mmHg above the palpated systolic pressure.
8. Release pressure no faster than 2 to 3 mmHg per second
9. The level at which the first clear sounds are hears is the SYSTOLIC PRESSURE
10. Continue to deflate the cuff until the sounds muffle and disappear and note the DIASTOLIC PRESSURE.
11. Record Systolic over Diastolic (110/70 mmHg)
Unexpected BP Readings
1. It is helpful to measure BP again toward the end of an interview with the client. Earlier pressures may be higher due to the stress of the clinical setting
2. The cuff must be completely deflated between attempts. Wait at least 1 full minute before reinflating the cuff. Air trapped in the bladder can cause a falsely high reading.
Complications of Blood Pressure and Nursing Interventions: Orthostatic (Postural) Hypotension
1. Assess for other related symptoms such as dizziness, weakness, and fainting.
2. Instruct client to activate call light and not get out of bed without assistance.
3. Have client sit at edge of bed for at least 1 minute before standing up. Assist with ambulation.
Home health considerations:
a) Warn of lightheadedness and dizziness
b) Advise client to sit or lie down when symptoms occur
c) Suggest client to get up slowly when lying or sitting and avoid sudden changes in position
Complications of Blood Pressure and Nursing Interventions: HYERTENSION
1. Assess for other symptoms (tachycardia, bradycardia, pain, anxiety). Primary hypertension is usually asymptomatic
2. Assess for identifiable causes of hypertension (renal disease, thyroid disease, medication)
3. Administer medication as prescribed
4. Assess for risk factors
5. Encourage lifestyle modification
HYPERTENSION: Lifestyle modification
1. Smoking cessation
2. Dietary modification: DASH (Dietary Approaches to Stop Hypertension) Diet - restrict sodium; consume adequate potassium, calcium, and magnesium. These minerals help lower BP; Restrict cholesterol and saturated fat intake
3. Weight control
4. Modification of alcohol intake
5. Stress reduction
6. Encourage follow up with physician.

Heaves or lifts are abnormal, visible elevations of the chest wall that are seen with heart failure, and are often located along the left sternal border or at the PMI
What is a THRILL
Use the ULNAR surface of the hand to feel for vibrations similar to that of a purring kitten. This is NOT AN EXPECTED FINDING.
AUSCULTATION OF THE HEART
Positioning the client in three different ways allows for optimal assessment of heart sounds, as some extra or abnormal sounds are accentuated by the various positions.
1. Sitting, leaning forward
2. Lying supine
3. Turned toward the left side (best position for picking up extra heart sounds, as some extra heart sounds or murmurs.
Determining the HEART RATE
Listen and count for 1 minute. Determine if rhythm is regular. If a dysrhythmia exists, check for a pulse deficit in which the radial pulse will be slower than the apical pulse.
Sites to assess for BRUITS ( produced by obstructed peripheral blood flow and are heard as a blowing or swishing sound with the Bell of the stethoscope).
1. Carotid arteries - over the carotid pulses
2. Abdominal aorta - just below the xiphoid process
3. Renal arteries - midclavicular lines above the umbilicus on the abdomen

5. Femoral arteries - over the femoral pulses.
Assessment of the ABDOMEN
a) Includes observing the shape of the abdomen, palpating for masses, and auscultating for vascular sounds
b) Use INSPECTION, AUSCULTATION, PERCUSSION and PALPATION. This is done to allow the bowel sounds to be heard without being disturbed or distorted by percussion or palpation assessments.
Preparing and positioning a client for an abdominal assessment
Have the client VOID prior to an abdominal examination. Position the client lying SUPNE with arms at his sides with his knees slightly bent.
Designated using the UMBILICUS. Imaginary vertical and horizontal lines pass through the umbilicus that divide the abdomen into 4 quadrants:
XIPHOID PROCESS - upper boundary
SYMPHYSIS PUBIS - lower boundary
1. Right Upper Quadrant - RUQ
2. Left Upper Quadrant - LUQ
3. Right Lower Quadrant - RLQ
4. Left Lower Quadrant - LLQ
ASSESSMENT FOR THE ABDOMINAL SKIN
1. Lesions - bruises, rashes or other lesions
2. Scars - location and length
3. Striae or stretch marks that are silver in color (expected findings)
4. Dilated veins - unexpected related to cirrhosis or inferior vena cava obstruction
5. Jaundice, cyanosis, or ascites - may be associated with cirrhosis
Bowel sounds are produced by the movement of air and fluid in the intestines. The most appropriate time to auscultate bowel sounds is in between meals
a) Listen with the diaphragm of the stethoscope in all four quadrants
b) Expected sounds are high pitched clicks and gurgles which are heard 5 to 30 times per minute. To determine for absent bowel sounds, you must listen for full 5 minutes without hearing anything.
Abdominal Friction Rubs
Caused by the rubbing together of the inflamed layers of the peritoneum.
1. Listen with diaphragm over the liver and the spleen
2. Ask client to take a deep breath while you listen for grating sounds like sandpaper rubbing together

b) Dullness over the liver or a distended bladder may be heard.
ASSESSMENT OF KIDNEY TENDERNESS
Assessed by FIST percussion over the costovertebral angles at the scapular lines on the back, The expected finding is no tenderness.
EXPECTED CHANGES WITH AGING: Breasts
With menopause, breast tissues atrophies and is replaced with adipose tissue, making it feel softer and more pendulous. The atrophied ducts may feel like thin strands. Nipples no longer have erectile ability and may invert.
EXPECTED CHANGES WITH AGING: Lungs
Chest shape changes. Chest expansion diminishes. Cough reflex diminishes. Cilia becomes ineffective. Alveoli dwindle and there is greater resistance and higher risk of infection. Kyphosis takes place due to osteoporosis and weakened cartilage.
EXPECTED CHANGES WITH AGING: Cardiovascular system
Systolic hypertension is common with atherosclerosis. PMI becomes more difficult to palpate. Coronary blood vessel walls thicken and become more rigid with a narrowed lumen. Cardiac output decreases, weak contraction leads to poor activity tolerance. Heart valves stiffen due to calcification. Left ventricle thickens. Pulmonary vascular tension increases. Systolic blood pressure rises. Peripheral circulation lessens.
