Which medication is used to prevent blood clots by thinning the blood, reducing the risk of stroke and heart attack?
- A. Anticoagulant
- B. ACE inhibitor
- C. Beta-blocker
- D. Calcium channel blocker
Correct Answer: A
Rationale: The correct answer is A: Anticoagulant. Anticoagulants prevent blood clots by thinning the blood, reducing the risk of stroke and heart attack. They work by inhibiting clot formation. ACE inhibitors (B), Beta-blockers (C), and Calcium channel blockers (D) are not used to prevent blood clots. ACE inhibitors are used to treat high blood pressure and heart failure, Beta-blockers are used to treat high blood pressure and heart conditions, and Calcium channel blockers are used to treat high blood pressure and certain heart conditions.

A client on an ACE inhibitor reports a persistent cough. What is the nurse's best response?
- A. Reassure the client that the cough is a common side effect and is usually not serious.
- B. Instruct the client to report the cough to the healthcare provider as it may require discontinuation of the medication.
- C. Advise the client to use a humidifier at night to relieve the cough.
- D. Suggest the client take an over-the-counter cough suppressant.
Correct Answer: B
Rationale: The correct answer is B because a persistent cough could indicate a serious side effect of ACE inhibitors, such as angioedema or bronchospasm. Instructing the client to report the cough to the healthcare provider is crucial to evaluate the need to discontinue the medication.
Choice A is incorrect as it downplays the potential seriousness of the cough. Choice C is incorrect because a humidifier may not address the underlying cause of the cough. Choice D is incorrect because using a cough suppressant without proper evaluation can mask symptoms of a serious side effect.
What is a condition where the arteries supplying blood to the legs and feet become narrowed or blocked, causing pain and difficulty walking?
- A. Peripheral artery disease
- B. Atherosclerosis
- C. Varicose veins
- D. Raynaud's disease
Correct Answer: A
Rationale: The correct answer is A: Peripheral artery disease (PAD). PAD is characterized by narrowed or blocked arteries in the legs and feet, resulting in reduced blood flow, causing pain and difficulty walking. This condition is specifically related to arterial issues, unlike varicose veins (C) which involve veins, atherosclerosis (B) which is a broader term for arterial plaque buildup, and Raynaud's disease (D) which is characterized by episodic vasospasm affecting blood flow to extremities. Therefore, PAD is the most accurate choice given the symptoms described in the question.
What is the condition where the blood flow through the coronary arteries is reduced or blocked, leading to chest pain or heart attack?
- A. Coronary artery disease
- B. Atherosclerosis
- C. Pulmonary embolism
- D. Pulmonary hypertension
Correct Answer: A
Rationale: The correct answer is A: Coronary artery disease. Coronary artery disease is the condition where there is reduced blood flow or blockage in the coronary arteries supplying blood to the heart muscle. This can lead to chest pain (angina) or a heart attack. Atherosclerosis is a buildup of plaque in the arteries, which is a major cause of coronary artery disease. Pulmonary embolism is a blockage in the arteries in the lungs, not the coronary arteries supplying the heart. Pulmonary hypertension is high blood pressure in the arteries of the lungs, not related to the coronary arteries. Therefore, the correct answer is A as it directly relates to the specific condition described in the question.
What is a condition where the heart's valves do not function properly, leading to disrupted blood flow within the heart?
- A. Valvular heart disease
- B. Myocarditis
- C. Endocarditis
- D. Aneurysm
Correct Answer: A
Rationale: The correct answer is A: Valvular heart disease. Valvular heart disease refers to conditions where the heart's valves do not function properly, leading to disrupted blood flow within the heart. This can result in symptoms like chest pain, shortness of breath, and fatigue. Myocarditis (B) is inflammation of the heart muscle, Endocarditis (C) is an infection of the inner lining of the heart, and Aneurysm (D) is a bulge in a blood vessel. These conditions do not specifically involve malfunctioning heart valves as seen in valvular heart disease.
Which term refers to high blood pressure, a condition where the force of the blood against the artery walls is too high?
- A. Hypertension
- B. Hypotension
- C. Hyperlipidemia
- D. Diabetes
Correct Answer: A
Rationale: The correct answer is A: Hypertension. Hypertension refers to high blood pressure, where the force of blood against artery walls is too high. This condition can lead to serious health issues. Hypotension (B) is low blood pressure. Hyperlipidemia (C) is high levels of fats/lipids in the blood. Diabetes (D) is a condition related to blood sugar regulation, not blood pressure. Therefore, A is the correct answer as it specifically relates to the condition described in the question.
