Cardiovascular Disease Questions and Answers Questions
Question 1 of 5
Which of the following is a correct statement about the pharmacodynamics of Beta-blockers for the treatment of heart failure?
Correct Answer: B
Rationale: Beta-blockers cause bradycardia (B) by reducing heart rate and contractility (negative inotropic effect), contrary to A. They're used with ACE/ARBs (D) but avoided in COPD (C).
Question 2 of 5
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.
Question 3 of 5
A patient newly diagnosed with hypertension asks the nurse what happens when uncontrolled hypertension is prolonged. The nurse explains that a patient with prolonged, uncontrolled hypertension is at risk for developing what health problem?
Correct Answer: A
Rationale: When uncontrolled hypertension is prolonged, it can result in renal failure, myocardial infarction, stroke, impaired vision, left ventricular hypertrophy, and cardiac failure. Glaucoma and anemia are not directly associated with hypertension.
Question 4 of 5
The home health nurse is caring for a patient who has a comorbidity of hypertension. What assessment question most directly addresses the possibility of worsening hypertension?
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.
Question 5 of 5
The depolarisation of cardiac muscle cells is characterised by:
Correct Answer: C
Rationale: The repolarisation phase of cardiac muscle cells involves potassium efflux through two types of potassium channels.
