A patient taking hydrochlorothiazide is also prescribed digoxin. Which lab value should the nurse monitor closely?

Sodium

Magnesium

Calcium

Potassium

Answer and Explanation

The Correct Answer is D

(A) Sodium: Thiazide diuretics can lower sodium, but hyponatremia does not directly affect digoxin toxicity.

(B) Magnesium: Magnesium is important for cardiac function but not as directly linked to digoxin toxicity as potassium.

(C) Calcium: Thiazides can cause hypercalcemia, but calcium does not significantly affect digoxin toxicity.

(D) Potassium: Thiazide diuretics (e.g., hydrochlorothiazide) cause potassium loss, which increases the risk of digoxin toxicity. Hypokalemia sensitizes the heart to digoxin’s effects, leading to arrhythmias.

Correct Answer is ["A","C","D","E"]

Explanation

(A) Benign Prostatic Hyperplasia (BPH): Enlarged prostate can obstruct urine flow, leading to postrenal AKI.

(B) Acute Tubular Necrosis: This is an intrarenal cause of AKI, resulting from direct kidney injury, not obstruction.

(C) Renal Calculi: Kidney stones blocking the ureter prevent urine excretion, causing back pressure on the kidneys.

(D) Ureteral Stricture: Narrowing of the ureter restricts urine outflow, leading to postrenal AKI.

(E) Bladder Tumor: A tumor in the bladder can obstruct urine passage, leading to kidney damage.

A. "It increases my urine output." B. "It reduces the reabsorption of sodium in my kidneys." C. "It decreases water reabsorption in my kidneys." D. "It helps retain water to maintain my blood pressure."

Correct Answer is D

Explanation

(A) "It increases my urine output." ADH reduces urine output by increasing water retention.

(B) "It reduces the reabsorption of sodium in my kidneys." ADH affects water reabsorption, not sodium regulation.

(C) "It decreases water reabsorption in my kidneys." ADH increases, not decreases, water reabsorption.

(D) "It helps retain water to maintain my blood pressure." ADH promotes water reabsorption in the kidneys, reducing urine output and increasing blood volume, which helps maintain blood pressure.
