Cardiovascular System Exam Questions And Answers

Correct Answer: B

Rationale: Blurred vision is a potential side effect of amiodarone. Instructing the client to report this symptom to the healthcare provider immediately is the most appropriate response. Choice A is incorrect because although blurred vision can be a common side effect of amiodarone, it should not be dismissed without further evaluation. Choice C is incorrect as advising the client to stop taking the medication without consulting the healthcare provider can be dangerous and is not the first course of action. Choice D is too drastic as discontinuing the medication should be done under the guidance of a healthcare provider after proper evaluation.

Correct Answer: A

Rationale: The correct answer is A, Angioplasty. Angioplasty is a procedure where a catheter is used to open blocked coronary arteries and may involve the insertion of a stent to improve blood flow to the heart muscle. Stent placement (B) is a related procedure but specifically refers to the insertion of a stent. Coronary artery bypass graft (CABG) (C) is a surgical procedure that uses blood vessels to bypass blocked coronary arteries. Valve replacement (D) is a different procedure that involves replacing a heart valve, not opening blocked coronary arteries.

Correct Answer: A

Rationale: The correct answer is A, Spirometry. Spirometry is a pulmonary function test that evaluates lung function by measuring the amount of air a person can exhale and how quickly, assisting in the diagnosis of conditions such as asthma and COPD. Choices B, C, and D are incorrect because Pulse oximetry measures oxygen saturation in the blood, Arterial blood gas (ABG) evaluates blood pH, oxygen, and carbon dioxide levels, and a Chest X-ray provides an image of the lungs but does not measure lung function.

Correct Answer: A

Rationale: The correct answer is A, Deep vein thrombosis (DVT). Deep vein thrombosis occurs when a blood clot forms in a deep vein, usually in the legs. If the clot dislodges and travels to the lungs, it can lead to a serious condition called a pulmonary embolism. Choice B, pulmonary embolism, is incorrect as it is the consequence of a DVT clot traveling to the lungs, not the initial condition. Choices C and D, varicose veins, and Raynaud's disease, respectively, are unrelated conditions to the formation of blood clots in deep veins.

Correct Answer: C

Rationale: The correct answer is the left ventricle. It receives oxygenated blood from the left atrium and pumps it to the rest of the body through the aorta. The left atrium receives oxygenated blood from the lungs, the right atrium receives deoxygenated blood from the body, and the right ventricle pumps deoxygenated blood to the lungs.
