Calcium is 10.1 mEq/L

D.

Potassium Level is 6.1mEq/L

Answer and Explanation

The Correct Answer is D

(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 A

Explanation

(A) Hyponatremia: SIADH leads to excess ADH secretion, causing water retention, dilution of sodium levels, and hyponatremia.

(B) Hypokalemia: SIADH does not primarily affect potassium.

(C) Hypernatremia: Excess ADH dilutes sodium, leading to low sodium levels, not high.

(D) Hyperkalemia: SIADH primarily causes hyponatremia, not potassium imbalances.

Correct Answer is C

Explanation

(A) 0.45% NaCl (Hypotonic Fluid): Used for mild dehydration but can cause fluid shifts leading to cerebral edema.

(B) 3% NaCl (Hypertonic Fluid): Used for severe hyponatremia, not dehydration.

(C) Lactated Ringer’s (LR): This isotonic fluid replaces lost fluids and electrolytes, making it the best choice for severe dehydration, especially in patients with electrolyte imbalances.

(D) D5W: Initially isotonic but becomes hypotonic once glucose is metabolized, leading to fluid shifts into cells, worsening dehydration.
