A nursing instructor asks a student at what point it is appropriate to treat hyponatremia. Which response by the student is accurate?
1. "When serum levels fall below 130 mEq/L."
2. "When serum levels fall below 140 mEq/L."
3. "When serum levels fall below 145 mEq/L."
4. "When serum levels fall below 155 mEq/L."
Correct Answer: 1
Rationale 1: Sodium chloride is administered for hyponatremia when serum levels fall below 130 mEq/L.
Rationale 2: A sodium level of 140 mEq/L is a normal value and does not require treatment.
Rationale 3: A sodium level of 145 mEq/L is a normal value and does not require treatment.
Rationale 4: A sodium level of 155 mEq/L indicates that a client is hypernatremic. It would be inappropriate to administer sodium chloride at this time.
Global Rationale: Sodium chloride is administered for hyponatremia when serum levels fall below 130 mEq/L. A sodium level of 140 mEq/L and 145 mEq/L are normal values and do not require treatment. A sodium level of 155 mEq/L indicates that a client is hypernatremic. It would be inappropriate to administer sodium chloride at this time.
