A patient has come to the clinic for a follow-up assessment that will include a BP reading. To ensure an accurate reading, the nurse should confirm that the patient has done which of the following?
Correct Answer: A
Rationale: Prior to the nurse assessing the patient's BP, the patient should try to rest quietly for 5 minutes. The forearm should be positioned at heart level.

Question 5 of 5
Which combination of medicines should be prescribed to a 62-year-old woman who has just been diagnosed with hypertension. She smokes 20 cigarettes per day, her cholesterol is 4.2 mmol/L. Her blood pressure is 147/85 mmHg. Her BMI is 29. Her QRISK3 score is 12%.
Correct Answer: B
Rationale: For a 62-year-old with hypertension and a QRISK3 of 12%, a statin (atorvastatin) is indicated due to cardiovascular risk, and amlodipine is a first-line antihypertensive for those over 55. Aspirin is not routinely indicated without established CVD, and furosemide is not first-line for hypertension.
