Correct answer: E — Two seated readings one minute apart, twice daily for seven days; discard day one

Explanation lettering: E = shown as A · D = shown as C · C = shown as D · A = shown as E

A is correct. NICE recommends two consecutive seated measurements at least one minute apart, twice daily, for at least four and ideally seven days; day-one values are discarded and the remainder averaged. A validated upper-arm device, correct cuff, rest and consistent technique matter. B deliberately changes posture and exercise state. C uses symptom-triggered sampling and a less reliable site. D is neither the recommended timing nor averaging method. E samples too sparsely. HBPM complements clinical assessment and is not converted arithmetically into the KDIGO standardised-office target.
