Correct Answer is C
Explanation
(A) Administer Corticosteroids: PKD is not an inflammatory disease, so steroids are not the first-line treatment.
(B) Encourage Dietary Protein Intake: High-protein diets can worsen kidney damage in PKD patients.
(C) Monitor Blood Pressure: Hypertension is a common and serious complication of PKD. Controlling blood pressure can slow disease progression and reduce the risk of further kidney damage.
(D) Prepare for Immediate Dialysis: Dialysis is not required unless the patient has end-stage renal disease (ESRD). Early-stage PKD is managed with symptom control and blood pressure management.
Correct Answer is D
Explanation
(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.
