Question 1 of 5
A nurse is monitoring a client who is dehydrated. Which of the following laboratory findings should the nurse report to the provider?
Correct Answer: C
Rationale: An elevated BUN level (25 mg/dL) is above the normal range (10-20 mg/dL) and indicates dehydration due to increased protein breakdown and decreased renal perfusion, requiring immediate reporting to the provider.
Question 2 of 5
A nurse is collecting data from a client who has dehydration. Which of the following findings should the nurse expect?
Correct Answer: C
Rationale: Cool skin is a typical finding in dehydration due to reduced peripheral circulation and vasoconstriction as the body maintains core temperature and blood pressure.
Question 3 of 5
A nurse is reviewing the medical record of a client and identifies a serum potassium 6.8 mEq/L (3.5-5 mEq/L). Which of the following medications should the nurse expect to administer?
Correct Answer: C
Rationale: Sodium polystyrene (Kayexalate) treats hyperkalemia by exchanging sodium for potassium in the intestines, promoting potassium elimination, suitable for a dangerously high potassium level of 6.8 mEq/L.
Question 4 of 5
A nurse is caring for a client whose serum potassium level is 5.3 mEq/L (3.5-5 mEq/L). The nurse should anticipate a prescription for which of the following medications?
Correct Answer: C
Rationale: Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by lowering serum potassium levels through ion exchange in the intestines.

A nurse is collecting data from a client who has a calcium level of 8 mg/dL (9.0-10.5 mg/dL). Which of the following manifestations should the nurse expect?
Correct Answer: D
Rationale: Tetany, involving muscle cramps and spasms, is a common manifestation of hypocalcemia due to increased neuromuscular excitability at low calcium levels.
