Rationale: Hypernatremia is defined as an elevated serum sodium level above 145mEq/L. In this case, a serum sodium level of 150mEq/L indicates hypernatremia. The other options, serum osmolality of 245mOsm/kg and urine specific gravity below 1.003, are not specific criteria for the diagnosis of hypernatremia. The primary marker used for diagnosing hypernatremia is an elevated serum sodium level.

Correct Answer: A

Rationale: An adequate respiratory condition can be indicated by a normal respiratory rate. The normal adult respiratory rate typically ranges from 12 to 20 breaths per minute.
