Correct answer: D — Urea, creatinine, eGFR and electrolytes

ACE inhibitors can reduce renal function and increase potassium, especially after initiation or dose changes. In this vignette, "Urea, creatinine, eGFR and electrolytes" is the safest single best answer. The other options are less appropriate because they miss the key clinical risk, conflict with UK medicines guidance, or delay needed review.
