Serum Glucose Levels
Heart Rate
Respiration Rate
Urine Output
Serum Potassium Levels
Correct Answer : D,E
(A) Serum Glucose Levels: Mannitol does not significantly affect glucose metabolism.
(B) Heart Rate: It does not directly impact heart rate, though secondary effects like dehydration may influence it.
(C) Respiration Rate: Mannitol does not directly impact respiratory function.
(D) Urine Output: Mannitol is an osmotic diuretic that increases urine output. Monitoring urine output helps assess the drug’s effectiveness and prevent dehydration or hypovolemia.

Explanation
(A) Magnesium is 2.0 mEq/L: Normal range (1.5-2.5 mEq/L), not concerning.
(B) Sodium Level is 136 mEq/L: Normal range (135-145 mEq/L), no immediate risk.
(C) Calcium is 10.1 mEq/L: Normal range (8.5-10.5 mEq/L), not a concern.
(D) Potassium Level is 6.1 mEq/L: Spironolactone is a potassium-sparing diuretic, and hyperkalemia can lead to life-threatening cardiac arrhythmias.
Correct Answer is D
Explanation
(A) Hypernatremia: PTH does not significantly affect sodium levels.
(B) Hyponatremia: PTH imbalance does not cause sodium depletion.
(C) Hypocalcemia: Hyperparathyroidism increases calcium levels, not decreases them.
(D) Hypercalcemia: Hyperparathyroidism causes excessive secretion of parathyroid hormone (PTH), which increases calcium release from bones, enhances calcium absorption in the intestines, and reduces calcium excretion by the kidneys, leading to hypercalcemia.
