The nurse has just finished teaching a hypertensive patient about the newly prescribed ramipril(Altace). Which patient statement indicates that more teaching is needed?

Correct Answer: A

Rationale: Angioedema occurring with angiotensin-converting enzyme(ACE) inhibitor therapy is an indication that the ACE inhibitor should be discontinued. The patient should be taught that if any swelling of the face or oral mucosa occurs, the health care provider should be immediately notified because this could be life threatening. The other patient statements indicate that the patient has an accurate understanding of ACE inhibitor therapy.

Correct Answer: D

Rationale: To identify complications or worsening hypertension, the patient is questioned about blurred vision, spots in front of the eyes, and diminished visual acuity. The heart, nervous system, and kidneys are also carefully assessed, but angina pain and decreased energy are not normally suggestive of worsening hypertension. Sodium limitation is a beneficial lifestyle modification, but nonadherence to this is not necessarily a sign of worsening symptoms.

Correct Answer: C

Rationale: The repolarisation phase of cardiac muscle cells involves potassium efflux through two types of potassium channels.

Correct Answer: B

Rationale: Central venous pressure averages around 6.4 mmHg and fluctuates with respiration and heart action.

Correct Answer: D

Rationale: Both statements are factually correct but the reason does not explain the assertion.
