Cardiovascular System Practice Exam
1. For what reason might the nurse be given an order to administer milrinone (Primacor)?
- A. For congestive heart failure
- B. For hypertension
- C. For cardiac arrhythmias
- D. For bradycardia
Correct answer: A
Rationale: Milrinone is commonly prescribed for congestive heart failure to help improve cardiac function and alleviate symptoms. Choices B, C, and D are incorrect as milrinone is not typically used for hypertension, cardiac arrhythmias, or bradycardia. It is specifically indicated for congestive heart failure for short-term management.
2. The nurse is giving the client digoxin for heart failure and recognizes that the drug has what type of effect on the heart?
- A. Negative inotropic, negative chronotropic effect
- B. Positive inotropic, negative chronotropic effect
- C. Negative inotropic, positive chronotropic effect
- D. Positive inotropic, positive chronotropic effect
Correct answer: B
Rationale: The correct answer is B: Positive inotropic, negative chronotropic effect. Digoxin strengthens the heart muscle, providing a positive inotropic effect, which increases the force of contraction. It also decreases the heart rate, having a negative chronotropic effect. Choice A is incorrect because digoxin has a positive inotropic effect, not a negative inotropic effect. Choice C is incorrect as digoxin does not have a positive chronotropic effect but a negative one. Choice D is incorrect because while digoxin has a positive inotropic effect, it does not have a positive chronotropic effect.
3. What is the condition where the blood vessels that supply blood to the legs and feet become narrowed or blocked, causing pain and difficulty walking?
- A. Peripheral artery disease
- B. Raynaud's disease
- C. Varicose veins
- D. Pulmonary embolism
Correct answer: A
Rationale: The correct answer is A, Peripheral artery disease (PAD). PAD is a condition where the blood vessels that supply blood to the legs and feet become narrowed or blocked, leading to decreased blood flow, pain, and difficulty walking, especially during physical activity. Raynaud's disease (choice B) is characterized by vasospasms in the fingers and toes, causing them to turn white or blue. Varicose veins (choice C) are enlarged, twisted veins usually found in the legs. Pulmonary embolism (choice D) is a blockage in one of the pulmonary arteries in the lungs, often caused by a blood clot.
4. The nurse is administering an ACE inhibitor to a client. What is the most common side effect?
- A. Cough
- B. Dizziness
- C. Hypotension
- D. Hyperkalemia
Correct answer: A
Rationale: The correct answer is A: Cough. Cough is a well-known side effect of ACE inhibitors due to an increase in bradykinin levels. This irritating cough can be bothersome to clients and should be monitored. Choice B, Dizziness, is not the most common side effect of ACE inhibitors. While ACE inhibitors can cause hypotension (Choice C), cough is more prevalent. Hyperkalemia (Choice D) is a possible side effect of ACE inhibitors but is less common compared to cough.
5. Which condition occurs when the heart muscle is damaged due to a lack of oxygen, often resulting from a heart attack?
- A. Myocardial infarction
- B. Angina
- C. Pericarditis
- D. Pulmonary embolism
Correct answer: A
Rationale: The correct answer is A: Myocardial infarction. Myocardial infarction, commonly known as a heart attack, is the condition where the heart muscle is damaged due to a lack of oxygen, typically caused by a blocked coronary artery. Angina (choice B) is chest pain or discomfort that occurs when the heart muscle doesn't receive enough oxygen-rich blood. Pericarditis (choice C) is the inflammation of the pericardium, the thin sac-like membrane surrounding the heart. Pulmonary embolism (choice D) is a blockage in one of the pulmonary arteries in the lungs, often caused by a blood clot.
