Chart on 1455!!!

64
Q

Describe the Renin-Angiotensin-Aldosterone System.

A

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
Q

Describe the atrial natriuretic factor.

A

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
Q

91
Q

What are treatment options for hypernatremia?

A

If Na+ gain:
-Diuretics AND Po or IV water replacement
(give diuretics to get rid of sodium and replace with water)

If water loss:
-Po or IV water replacement

**hypernatremia is corrected slowly (over 2 days) due to risk for cerebral edema

92

Ca 12 mg/dL is a medical emergency and can lead to life threatening cardiac dysrhthmias

Parathyroid Hormone: increases bone resorption, meaning it is pulling calcium from the bone, Activates vitamin D in GI tract and stimulates kidneys to hold onto calcium

Calcitonin:: inhibits bone resortpion. Keeps calcium within the bone. Nasal spray available.
dairy, green leafy vegetables, salmon, cereals, orange juice, etc.

94
Q

What is hypocalcemia and what are the causes?

A

Hypocalcemia: Low calcium

  • Ca+ losses
    • Cigarette smoking can increase urinary Ca+ excretion
  • Decreased intestinal absorption
    • excessive ETOH/caffeine can inhibit Ca+ absorption
  • Inadequate vitamin D intake

Diuretics get rid of ALL electrolytes

95
Q

What are mechanisms that react to decreased serum Ca+ levels?

A
  1. parathyroid hormone secretion
    intestinal absorption of Ca+
    >release of Ca+ from bone (bone resorption)
    >serum Ca+
2. < serum Ca+
>activation of vitamin D
>intestinal absorption of Ca+
>release of Ca+ from bone
>serum Ca+
96

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
Q

What is hypokalemia and what are the causes?

A

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
Q

What are signs and symptoms of hypokalemia?

A
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
Q

What are treatment options of hypokalemia?

A

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
Q

What are nursing implications of hypokalemia?

A
Prevention
Identify @ risk patients
Observe for s/s
Careful monitoring of IV administration
Assess renal function
Patient education
109
Q

What is the correlation between digoxin and potassium?

A

Someone taking Digoxin is at risk for Digoxin Toxicity if the person becomes hypokalemic

110
Q

What is hyperkalemia and what are the causes?

A

Hyperkalemia: too much potassium
Serum level >5.0 mEq/L

Increased intake-usually IV

Decreased excretion

Shift of K+ out of cell

111
Q

What are signs and symptoms of hyperkalemia?

A
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
Q

What are treatment options for hyperkalemia?

A
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
