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

Loop diuretics can disturb fluid balance and electrolytes, especially in CKD. 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.
