Correct answer: A. I will follow the prescribed fluid limit and report headache or confusion

- B. I will drink unlimited water to prevent every possible complication
- C. I will stop desmopressin whenever my urine becomes less frequent

Explanation
Desmopressin reduces urine production, so excessive fluid intake can cause water retention and hyponatraemia. Headache, confusion, nausea or seizures may indicate serious hyponatraemia and require urgent reporting.
