Cardiovascular System Quiz Questions Questions
Question 1 of 5
The nurse should monitor a client with an acute myocardial infarction who is receiving intravenous streptokinase (Streptase) for which of the following serious adverse reactions?
Correct Answer: A
Rationale: Streptokinase (A), a thrombolytic, risks intracranial hemorrhage, a life-threatening complication. Nausea (B), MI extension (C), and embolus (D) are less directly related.
Question 2 of 5
In a client with mitral regurgitation the nurse would expect to see which of the following signs and symptoms?
Correct Answer: C
Rationale: Mitral regurgitation causes blood to flow back into the left atrium, leading to pulmonary congestion and exertional dyspnea (shortness of breath with activity). Crushing chest pain is more typical of myocardial infarction, and elevated WBC suggests infection, not regurgitation directly.
Question 3 of 5
After receiving a permanent pacemaker, the client asks the nurse if there are any activities to avoid during a vacation scheduled for 4 months after discharge. Which of the following is the most appropriate response by the nurse?
Correct Answer: B
Rationale: Four months post-pacemaker, most activities are safe, but strong electromagnetic fields (e.g., running engines) can interfere with pacemaker function. Microwaves and swimming are generally safe once healed.
Question 4 of 5
Excessive alcohol use while on warfarin sodium (Coumadin) therapy leads to:
Correct Answer: C
Rationale: Excessive alcohol increases warfarin's anticoagulation effect by impairing liver metabolism, raising bleeding risk. INR increases (not decreases, B), and vitamin K absorption (D) is unaffected; A is the opposite effect.
Question 5 of 5
The heart is located in the:
Correct Answer: A
Rationale: The heart is situated in the thoracic cavity, specifically within the mediastinum, between the lungs. The abdominal cavity (Choice B) contains organs like the stomach and liver, the pelvic cavity (Choice C) houses reproductive and urinary organs, and the cranial cavity (Choice D) contains the brain. Only the thoracic cavity correctly identifies the heart’s location.
