The Daily PANCE and PANRE Question 40

A 51-year-old male with renal artery stenosis and an elevated BUN and creatinine is newly diagnosed as hypertensive. Which of the following agents should be avoided?

  1. hydrochlorothiazide-triamterene
  2. prazosin
  3. nifedipine
  4. verapamil
  5. furosemide

Answer: A

Hydrochlorothiazide-triamterene

This is a potassium-sparing diuretic and should be avoided in anyone with renal disease. ACEI should be avoided as well (but none of these are ACEI's).
