Q

How do you deliver culturally responsive care?

A

Nurse must first develop self-awareness of his/her own cultures, attitudes, and beliefs

Examine the biases and assumptions nurse holds about different cultures.

Nurse needs to gain necessary knowledge and skills to create an environment of trust between nurse and client.

Knowledge needs to include understanding of health disparities, historical and current portrayals of racial and ethnic groups in society.

Cultural understanding, avoiding generalizations, and obtaining cultural assessment skills are essential in understanding client’s viewpoint, and learning what the client values as important.

52
The body's fluid is divided into what two major compartments?
Intracellular fluid: Found within the cells of the body. Constitutes approximately two thirds of the total body fluid in adults. Extracellular fluid: Found outside the cells and accounts for about one third of total body fluid. ECF is further subdivided: Intravascular fluid (plasma): Found within the vascular system. 20% Interstitial fluid: Surrounds the cells. 75%. Lymph Transcellular fluids: Cerebrospinal, pericardial, pancreatic, pleural, intraocular, biliary, peritoneal, synovial fluids.
53
What are the functions of the intracellular and extracellular fluid?

55
What are non electrolytes?

Average adult drinks 1,500 mL/day but needs 2,500 mL Additional 1000 mL if from foods and metabolic processes. Oral fluids: 1,200-1,500 Water content of food= 1000 mL/day Water as a by-product of food metabolism=200 mL Total=2,400-2,700
58
Describe the thirst mechanism.
Thirst mechanism: primary regulator of fluid intake. Located in the hypothalamus of the brain. Osmotic pressure of body fluids, vascular volume, and angiotensin are stimuli that trigger the thirst center, causing the sensation of thirst and the desire to drink fluids.
59
Describe the average daily fluid output for an adult.

61
What hormones monitor and maintain vascular volume?
- ADH (also known as arginine vasopression) - Renin-angiotensin-aldosterone system - Atrial natriuretic factor
62
Describe the kidneys.
Primary regulator of body fluids and electrolyte balance. Regulate volume and osmolality of ECF by regulating water and electrolyte excretion. Control reabsorption of water from plasma filtrate and the amount excreted as urine. 135 to 180 L of plasma is filtered per day in an adult, but only 1.5 L of urine is excreted. Regulation of pH of ECF by retention of H+ ions Excretion of metabolic wastes and toxic substances.
63
Describe ADH.
ADH regulates water excretion from the kidney Is synthesized in the anterior portion of the hypothalamus Acts on the collecting ducts of the nephrons. Chart on 1455!!!
64
Describe the Renin-Angiotensin-Aldosterone System.
Contributes to maintaining fluid balance. Specialized receptors in the kidneys respond to changes in renal perfusion. If blood flow or pressure to the kidney decreases, renin is released. Stimulates the release of aldosterone from the adrenal cortex. Aldosterone also promotes sodium retention in the distal nephron. The net effect of this is an increase volume through sodium and water retention.
65
Describe the atrial natriuretic factor.
Released from cells in the atrium of the heart in response to excess blood volume and stretch in got the atrial walls. Acting on the nephrons, ANF promotes sodium wasting and acts as a potent diuretic, decreasing blood volume. Inhibits thirst, reducing fluid intake.
66
What parts of the body affect fluid & electrolyte homeostasis?
KIDNEYS Heart & blood vessels Lungs Pituitary gland Adrenal glands Parathyroid glands
67
What are factors that increase the influence of ADH?
``` Decreased ECF Decreased BP Stress Pain Medications like morphine and barbiturates Surgery and anesthetics ```

Describe Potassium's role within the body.
- Major cation in ICF fluids - Transmitting nerve and other electrical impulses - Regulating cardiac impulse transmission and muscle contraction - Skeletal and smooth muscle function - Regulation acid/base balance (H+ concentration) - Kidneys primary regular of K+ - Serum level = 3.5-5 mEq/L A serum K of 6.5 mEq/L is a medical emergency and can lead to life threatening cardiac dysrhythmias Someone on lasix and digoxin is at risk for dig toxicity so they need to be on high potassium diet (potatoes, dried fruits, bananas, oranges, avocados
105
What is hypokalemia and what are the causes?
Hypokalemia= low potassium Serum K+ <3.5 mEq/L Decreased total body K+ - Diuretics - Upper GI losses - Diaphoresis Intracellular shift - Increased insulin - alkalosis Rarely due to inadequate intake
106
What are signs and symptoms of hypokalemia?
``` Fatigue Muscle weakness N/V Leg cramps Decreased bowel sounds Weak, irregular pulse Increased digitalis effect ABG's may show metabolic alkalosis Cardiac arrest if severe ```
107
What are treatment options of hypokalemia?
Treat underlying cause K+ replacement K+ sparing diuretics KCL salt substitue Potassium pills are huge. Potassium liquid is an awful tasting liquid so stick it in something else. Will NEVERr be giving potassium IV and potassium po at the same time.
108
What are nursing implications of hypokalemia?
``` Prevention Identify @ risk patients Observe for s/s Careful monitoring of IV administration Assess renal function Patient education ```
109
What is the correlation between digoxin and potassium?
Someone taking Digoxin is at risk for Digoxin Toxicity if the person becomes hypokalemic
110
What is hyperkalemia and what are the causes?
Hyperkalemia: too much potassium Serum level >5.0 mEq/L Increased intake-usually IV Decreased excretion Shift of K+ out of cell
111
What are signs and symptoms of hyperkalemia?
``` Irritability Anxiety Abdominal cramping Diarrhea Weakness Irregular pulse ABG's may show metabolic acidosis Cardiac arrest ``` Irritability: new symptom Diarrhea can be a symptom of hyperkalemia, but also can be a reason the body is starting to get rid of potassium, if they get rid of too much and are on dig then can cause hypokalemia. If you have diarrhea and are on digoxin then you are calling the doctor.
112
What are treatment options for hyperkalemia?
``` Restriction of po K+ and K+ containing meds Kayexalate Diuretics IV Calcium gluconate IV glucose and insulin Dialysis NaHCO3 Bedrest until serum K+ returns to WNL ``` Have to know electrolyte level before giving treatment Calcium gluconate pushes potassium back into the cells. Bedrest: want to rest the heart as much as possible as a safety measure
113
What are nursing implications included for hyperkalemia?
``` Prevention Identify @ risk patients Observe for s/s Careful monitoring of IV administration Patient Education ``` Potassium is responsible for maintaining the heart beat
