Question 1 of 5
Which of the following vitamin D preparations would be the most appropriate in a patient with poor renal function?
Correct Answer: B
Rationale: Calcitriol (choice B), active 1,25-dihydroxyvitamin D, bypasses renal activation, ideal for poor renal function where 1-alpha-hydroxylation is impaired. Calcifediol (choice A), Cholecalciferol (choice C), and Ergocalciferol (choice D) require renal conversion, less effective here. Calcitriol directly corrects hypocalcemia.
