A private wrong, by act or omission that can result in civil action

Tort

A patient does not want an IV, but you give it anyways

Intentional Tort

The unjustifiable attempt or threat to touch a person without consent resulting in fear of immediately harmful or threatening contact

Assault - touching need not actually occur

Unlawful, harmful, or unwarranted touching of another or carrying out of threatened physical harm

Battery - touching without consent is considered battery, regardless of intent or outcome

4 Requirements to be considered MALPRACTICE

1. It must be established that the nurse had a duty to the patient - Assignments
2. A breach of standards of care or failure to carry out that duty must be proven
3. The patient must suffer actual harm or injury
4. There must be a causal relationship between the breach of duty and the injury suffered

The recipient of care
Guidelines by which the nurse should practice

Standards of Nursing Practice focuses on

obligation to be fair

Defined by TJC as an unanticipated event that causes the death, or serious physical or .psychological injury to a person - not related to a patient's natural course of illness

Sentinel Event

N95 - Remove the mask as soon as you get OUT of the room.

Scope of Practice - the LPN may NOT initiate or maintain:

Blood/ Blood Components

routine dressing changes at the insertion sie, peripheral venous, arterial, PICC & CVC

Contains the fluid inside the billions of cells within the body; Largest of the two compartments

Intracellular fluid

Contains any fluid outside the cell; Divided into interstitial and intravascular compartments.

Extracellular Fluid

Fluid betweein the cells or in the tissue
Ex: Lymph, CSF. and GI secretions

40-50 mL per hour...minimum of 30

Electrolytes that are not stored and must be consumed daily

Sodium, chloride, Potassium

No cellular energy is required to move substances from a high concentration to a low concentration

Passive Transport

Cellular energy is required to move substances from low concentration ot high concentration

Active Transport

The movement of particles in all directions through a solution or gas. Solutes move from area of higher concentration to an area of lower concentration, resulting in an equal distribution of solutes within the two areas

Diffusion

The movement of water from an area of lower concentration to an area of higher concentration

Osmosis

A solution of higher osmotic pressure
Pulls fluid from the cells - cells to vascular

**Hypertonic Solutions - ABOVE 375**

A solution of the same osmotic pressure
Expands the body's fluid volume WITHOUT causing a fluid shift

**Isotonic Solutions - 250-375**

A solution of lower osmotic pressure
Moves into the cell, causing them to enlarge

**Hypotonic Solutions - Below 250**

Anions (Negative charge)

Chloride
Bicarbonate
Phosphate
Sulfate

Cations (positive charge)

Sodium
Potassium
Calcium
Magnesium

A balance of cations and anions should exist, if not...

the body will not be in homeostasis

If a patient is receiving hypertonic solution, they are receiving it through

Osmosis

If O2 is going from arteries to capillaries

Diffusion

Normal Lab levels of sodium

Major source of sodium

Diet

Sodium levels less than 135 - can occur where there is sodium loss or a water excess. Holds onto water to increase sodium. Likely to have a potassium imbalance as well

HYPOnatremia - decreased BUN , dry mucous membranes, thirsty

Symptoms of hyponatremia

Muscle Weakness
Muscle Twitching
Decreased Skin Turgor
Headache
Tremor, seizures, or coma

Treatment of hyponatremia

Dietary replacement, can use enteral route, or parenteral route. Replace sodium and fluid losses as well as correcting other electrolye imbalances

Sodium levels greater than 145 Sodium excess or water loss. Causes fluid to shift from the cells to the interstitial spaces, resulting in cellular dehydration

Kussmaul's respirations - muscle weakness, malaise, headache,

Metabolic acidosis

common cause is hyperventilation, anxiety, fever
any lung disease that leads to SOB & hypoxia - pneumonia,
mental status change, pallor around mouth, tingling fingers, spasm of hand muscles

Respiratory acidosis

Treatment of respiratory acidosis

breathe intoa paper bag

sever sutained vomiting or NG suctioning(removes too much pH) - overdose of baking soda or antacids
symptoms: confusion, dyspnea, drowsiness, hypeerkalemia, weakness

Metabolic alkalosis

what are the 3 systems that work to keep the pH in normal range?

Blood Buffers
Lungs
Kidneys

The ratio needed for homeostasis of carbonic acid to bicarbonate is....

Lungs job in acid base balance

speeds up or slows down respirations to increases or decrease carbon dioxide in the blood
