The nurse checks the results of lab tests for Mrs. Morris and notes that the potassium level is 2.8 mEq/L. After reporting this finding to the physician, the nurse assesses the client for:
a. a weak, irregular pulse.
b. increased peristalsis.
c. a bounding pulse.
The physician's order reads flush NG tube with 30 to 50 ml saline solution for irrigation q2h prn. The nurse knows that saline solution is used instead of water because:
a. flushing with water can deplete electrolytes in the stomach.
b. water is irritating to the gastric mucosa.
c. the sterility of the stomach is maintained with saline solution.
d. saline is better in maintaining tube patency.
Mrs. Morris is started on hydrocortisone 25 mg Intravenous push IVP. The primary reason for administering this drug to Mrs. Morris is that:
a. it is a corticosteroid and will make Mrs. Morris feel better.
b. Mrs. Morris needs to continue on corticosteroids, but have a different administration route due to nausea.
c. it will protect Mrs. Morris from infection.
d. it will replace the loss of electrolytes through the GI tract.
Mrs. Morris is given intravenous fluids of lactated Ringer's solution. Which of the following describes the properties of lactated Ringer's?
a. Lactated Ringer's contains electrolytes and is a hypertonic solution.
b. Lactated Ringer's is a hypotonic solution used for fluid volume replacement.
c. Lactated Ringer's provides fluid and does not contain electrolytes.
d. Lactated Ringer's is an isotonic solution and provides electrolytes.
The nurse notes that Mrs. Morris's NG tube is draining a moderate amount of coffee ground material. The appearance of coffee ground gastric drainage indicates:
a. active gastric bleeding.
b. bleeding from the lower GI tract.
c. stasis of digested foods.
d. blood that has begun to be digested by the gastric secretions.
The nurse understands that clients who are hypovolemic can manifest a:
a. low hematocrit level.
b. high hematocrit level.
c. normal hematocrit level.
d. hematocrit level that is unaffected by fluid volume.
Chloride is found abundantly in the body. Which statement is correct regarding chloride?
a. Chloride is found in the intracellular fluid and helps to maintain water balance.
b. Chloride is found in the extracellular fluid and helps to maintain water balance and acid-base balance.
c. During periods of excessive loss of fluids, such as vomiting, chloride is not depleted.
d. Chloride is the major intracellular anion that works with sodium to regulate water balance.
Sodium is found abundantly in the body. Which statement is correct regarding sodium?
a. Sodium is found in the intracellular fluid and helps to maintain water balance.
b. Sodium is regulated by the amount of daily oral intake.
c. Sodium regulation is controlled only by the kidneys.
d. Sodium is found in the extracellular fluid and helps to maintain water balance.
A client has experienced vomiting and diarrhea for several days. The nurse understands that the nursing interventions should include safety precautions because hypovolemia can lead to:
a. shortness of breath and pedal edema.
b. decreased cerebral circulation and postural hypotension.
c. abdominal distention and rapid pulse.
d. twitching and weak muscles.
On admission a client was confused and weak and complained of fatigue. Lab tests showed hypokalemia and hyponatremia. After 2 days of IV therapy and electrolyte replacement, the client tells the nurse that she feels much better. The most appropriate way to evaluate electrolyte balance in a client is to:
a. assess the client's level of orientation and her ability to respond appropriately to simple questions.
b. compare the client's vital sign readings, especially the pulse, to those taken on admission.
c. monitor lab results from admission to the most recent values.
d. review the nurse's document indicating improved skin turgor and mucous membranes.
(blank) spacing: excess accumulation of fluid in the interstitial spaces = edema
• Fluid can be pulled back into the intravascular space for removal by the kidneys
• Give Lasix to help the kidneys get rid of more, water moves back into the intravascular area for removal.
o (blank) spacing: accumulation of fluid in areas that normally do not have fluid. Ex. Ascites (fluid in the belly), Plural Effusion
• Fluid cannot be pulled back into intravascular space
• Must be removed by medical intervention (thoracenteses or paracentesis)
• Gain of more water than salt
• Loss of more salt than water
• Excessive general fluid loss
• Lose more water than salt
• Gain more salt than water
fluid volume deficit plus hypernatremia
• Most predominant cation in the ICF
• Crucial to heart function
• Plays a key role in skeletal and smooth muscle contraction
• Decreased potassium intake
• Shift of potassium into the cells
• Increased potassium output
• Increased intake of potassium
• Shift of potassium from ICF to ECF
• Decreased potassium output
• Necessary for muscle contraction
• If your levels are low, the body steals it from the bones
• Decreased calcium intake and/or absorption
• Shift of calcium into the bone
• Increased calcium output
• Increased calcium intake and absorption
• Shift of calcium out of the bone
• Decreased calcium output
• Necessary for optimal function of neuromuscular junctions
• Cofactor for numerous enzymes
• Aids in the absorption of Calcium, Potassium, and Vitamin D
• Decreased intake and/or absorption
• Shift of magnesium into inactive form (FYI)
• Increased magnesium output
• Increased magnesium intake and absorption
• Decreased magnesium output
• Most often caused by renal failure
o Uncommon with appropriate renal function - rapid elimination

• Phosphorus & Calcium
• Most abundant electrolyte in the body (mostly in bone)
• Most predominant anion in the ECF
• Major role in maintaining fluid balance
• Major component in bones and teeth
• Cofactor for numerous enzymes
• Role in muscle contraction, blood coagulation, and transmission of nerve impulses
• Usually bound with either sodium (NaCl) or potassium (KCl)
• Severe vomiting & diarrhea
• Loss of gastric fluid
• Metabolic alkalosis

• Metabolic acidosis
o Competes with bicarbonate (FYI)
• Head Trauma
• Increased perspiration

NURS 171 ACID-BASE BALANCE
A circuit calls for a 0.50-mm-diameter copper wire to be stretched between two points. You don’t have any copper wire, but you do have aluminum wire in a wide variety of diameters. What diameter aluminum wire will provide the same resistance?
The harder you hit the brakes while driving forward, the more the front end of your car will move down (and the rear end move up). Why? What happens when cars accelerate forward? Why do drag racers not use front-wheel drive only?
Describe what would happen to the interference pattern in Young's double-slit experiment if the wavelength of the monochromatic light were to decrease.
Determine what happens to the double-slit interference pattern if one of the slits is covered with a thin, transparent film whose thickness is $\lambda / [2(n-1)]$, where $\lambda$ is the wavelength of the incident light and $n$ is the index of refraction of the film.
