Cardiovascular System Practice Exam

1. Which valve opens during ventricular systole and closes during ventricular diastole?

Correct answer: B

Rationale: The correct answer is B: Pulmonary valve. The pulmonary valve opens during ventricular systole to allow blood to flow from the right ventricle into the pulmonary artery. The aortic valve opens during ventricular systole to allow blood to flow from the left ventricle into the aorta. The mitral valve and tricuspid valve are atrioventricular valves that open during ventricular diastole to allow blood to flow from the atria into the ventricles.

2. The nurse is caring for a client on enalapril (Vasotec). What is the most important side effect to monitor?

Correct answer: A

Rationale: The correct answer is A: Cough. Enalapril is an ACE inhibitor, and cough is a common side effect associated with this class of medication. Monitoring for cough is crucial as it can indicate the development of a potentially serious condition known as angioedema. Hyperkalemia (choice B) is a possible side effect of ACE inhibitors but is not the most important side effect to monitor. Hypotension (choice C) and dizziness (choice D) are also potential side effects of enalapril; however, cough takes precedence due to its association with angioedema, a severe adverse reaction.

3. The nurse is administering enoxaparin (Lovenox) to a client. What is the most important lab value to monitor?

Correct answer: A

Rationale: The correct answer is A: Platelet count. When administering enoxaparin, it is crucial to monitor the platelet count because enoxaparin can lead to a rare but serious side effect known as thrombocytopenia, which is a decrease in platelet levels. Monitoring the platelet count helps in detecting this adverse effect early. Choices B, C, and D are incorrect because hemoglobin, white blood cell count, and aPTT are not the most important lab values to monitor specifically for enoxaparin administration.

4. The client on amiodarone reports shortness of breath. What is the nurse’s best response?

Correct answer: A

Rationale: When a client on amiodarone reports shortness of breath, it can be indicative of pulmonary toxicity, a severe side effect associated with this medication. The nurse's priority is to notify the healthcare provider immediately to assess the situation and determine the appropriate course of action. Choice B is incorrect because shortness of breath with amiodarone should not be dismissed as a common side effect. Instructing the client to monitor symptoms at home (Choice C) may delay necessary intervention. Suggesting the client reduce physical activity (Choice D) does not address the potential serious nature of the symptom and the need for prompt evaluation.

5. What is a chronic condition where the blood pressure in the arteries is persistently elevated, increasing the risk of heart disease and stroke?

Correct answer: A

Rationale: Hypertension, also known as high blood pressure, is a chronic condition characterized by persistently elevated pressure in the arteries. This condition increases the risk of heart disease, stroke, and other health issues. Hypotension (choice B) refers to low blood pressure and is not the correct answer. Hyperlipidemia (choice C) is high levels of fats in the blood, not related to blood pressure. Hyperglycemia (choice D) is high blood sugar levels, not directly related to elevated blood pressure.
