Correct answer: B — Check renal function and potassium soon after starting and after dose increases.

ACE inhibitors can increase potassium and alter renal function, especially in diabetes or renal disease. Baseline results are acceptable, but monitoring is required after initiation and dose escalation. HbA1c and thyroid function do not assess ACE inhibitor safety.
