-
Na+ (Sodium)
[lab value]
Na+ 135-145 mEq
-
Na+ (Sodium)
Functions and Considerations
- Na+ maintains:osmotic pressure acid-base balance assists in transmission of nerve impulses
- ! Drawing blood specimens from an extremity in which an IV solution is
- infusing can produce an inaccurate result, depending on the test being
- performed and type of solution infusing. Prolong use of a tourniquet and
- clenching and unclenching hand before venous sampling can increase the
- blood level of K+ producing an inaccurate result
-
K+ (Potassium)
[lab value]
K+ 3.5-5 mEq
-
K+ (Potassium)
[functions and considerations]
- K+ function:
- 1. cation
- 2. reg water balance
- 3. electrical conduction
- 4. acid-base balance
- K+ levels to evaluate:
- 1. renal function
- 2. cardiac function
- 3. GI function
- 4. need for IV replacement therapy
- K+ nursing considerations:
- 1. PT c/elevated WBCs and platelets counts may have falsely elevated potassium levels
-
Cl- (Chloride)
[lab value]
Cl- 98-107 mEq
-
HCO3 (Bicarbonate)
[lab value]
HCO3 22-26
-
Ca+ (Calcium)
[lab value]
Ca+ 8.6-10
-
Platelet Count
[lab value]
- Platelet Count 150K-400K
- 150,000 to 400,000
