Fluids & Electrolytes Flashcards
1
Q
CO2 level (bicarb)
A
23 - 29 mmol/L
1
Q
Specific gravity level
A
1.005 - 1.030
- Less than 1.005 = dilute urine, hypervolemia
- Greater than 1.030 = concentrated urine, hypovolemia
2
Q
Creatinine level
A
0.6 - 1.2 mg/dL
3
Q
BUN level
A
6 - 20 mg/dL
4
Q
Glucose level
A
70 - 110 mg/dL
5
Q
Platelet level
A
150,000 - 450,000 /uL
6
Q
Hemoglobin level
A
M: 13.5 - 17.5 g/dL
F: 12 - 16 g/dL
7
Q
WBC level
A
4500 - 10,500 / uL
8
Q
Hyperkalemia medical management
A
- Dietary modifications
- IV dextrose and insulin administration (glucose shift which K follows)
- Loop diuretics
- Kay-exalate (promote GI excretion of K)
- Severe: calcium to reverse arrythmias, not lower K
9
Q
Hyperkalemia clinical manifestations
A
- *Palpitations
- *EKG changes
- Paresthesias
- Generalized fatigue
- Muscle cramps
- Weakness
- Serious complications: cardiac arrest
10
Q
Hyperkalemia causes
A
- Acute or chronic renal failure (bc major excretor of K)
- Excessive intake of foods high in potassium: banana, potato, leafy greans
- Medications: potass-sparing diuretics, NSAIDs, potass supplements, beta blockers, digitalis
- Shift of intracellular potass to extracellular space: crush injuries, metabolic acidosis
11
Q
Hypokalemia medical management
A
- Potass supplement (oral preferred)
- Cardiac monitoring
- Intravenous access
*Monitor digoxin levels and administer potass slowly d/t arrhythmias + irritation
12
Q
Hypokalemia clinical manifestations
A
- Weakness and lethargy (d/t Na/K pumps & AP)
- N/V
- Constipation
- Abd cramping
- *ST depress on EKG
- Severe complication: cardiac or resp arrest
13
Q
Hypokalemia causes
A
- Losses in GI Tract (vomit, diarrhea, gastric suction, excessive laxative)
- Medications: loop diuretics, thiazide diuretics, aminoglycosides (antibiotic type), steroids, albuterol
- Lack of potassium rich foods
14
Q
Potass levels
A
3.5 - 5.0 mEq/L
15
Q
Chloride levels
A
97 - 107 mEq/L
16
Q
Hypernatremia medical management
A
- Limit sodium intake
- Replace water deficits w hypotonic fluids (anything less than 0.9% normal saline: D5W, 0.45%…)
17
Q
Hypernatremia clinical manifestations
A
- Nonspecific neurological symptoms: agitation, restlessness, neuromuscular irritability
- Severe: hallucinations, delusions, disorientation, coma
- Thirst
- Signs of dehydration: dry mouth, poor skin turgor, low BP, rapid HR, dark yellow urine
