A patient with hypertension who has just started taking atenolol(Tenormin) returns to the health clinic after 2 weeks for a follow-up visit. The blood pressure(BP) is unchanged from the previous visit. Which action should the nurse take first?

Correct Answer: B

Rationale: Because noncompliance with antihypertensive therapy is common, the nurse's initial action should be to determine whether the patient is taking the atenolol as prescribed. The other actions also may be implemented, but these would be done after assessing patient compliance with the prescribed therapy.

Correct Answer: B

Rationale: Atrial premature beats can cause an exaggerated 'A' wave in the jugular pulse due to increased atrial contraction against a closed or partially closed tricuspid valve.

Correct Answer: C

Rationale: Blood in the umbilical veins is highly oxygenated, being approximately 80% saturated with O2.

Correct Answer: A

Rationale: Without specific patient details, Ramipril (an ACE inhibitor) is a common first-line option for hypertension, especially in younger patients or those under 55, per guidelines like NICE. Amlodipine is also first-line but typically for older patients. Doxazosin is usually third-line, and Losartan is an ARB, often used if ACE inhibitors are not tolerated.
