The nurse should explain that which of the following medications puts a client at risk for developing hyperkalemia?
Furosemide (Lasix)
Spironolactone (Aldactone)
Sodium polystyrene sulfate (Kayexalate)
Insulin
The Correct Answer is B
A. Furosemide (Lasix) is a loop diuretic that typically causes the loss of potassium through the urine, thus putting clients at risk for hypokalemia, not hyperkalemia.
B. Spironolactone (Aldactone) is a potassium-sparing diuretic, meaning it helps the body retain potassium. As a result, it can lead to hyperkalemia, especially in patients with kidney dysfunction or when used with other medications that increase potassium levels.
C. Sodium polystyrene sulfate (Kayexalate) is used to treat hyperkalemia by exchanging sodium for potassium in the intestines, thus lowering potassium levels. It does not contribute to hyperkalemia.
D. Insulin does not directly cause hyperkalemia; in fact, insulin administration can lower potassium levels by driving potassium into cells.

Correct Answer is B
Explanation
A. Assessing blood pressure with a sphygmomanometer is unrelated to Chvostek's sign, which specifically evaluates neuromuscular excitability.
B. Chvostek's sign is assessed by tapping the facial nerve near the cheekbone. A positive response, such as twitching of the facial muscles, indicates hypocalcemia or neuromuscular irritability.
C. Assessing heart rate with a stethoscope does not involve evaluating neuromuscular function or calcium levels.
D. Monitoring respiratory rate with a pulse oximeter is unrelated to Chvostek's sign and does not assess neuromuscular excitability.
Correct Answer is ["75"]
Explanation
- Total volume: 1800 mL
- Infusion time: 24 hours
- Calculation: 1800 mL / 24 hours = 75 mL/hour
Therefore, the IV pump should be set to deliver 75 mL/hr.
