Cardiovascular System Exam Questions Pdf
1. Which neurotransmitter is released by the sympathetic nervous system (SNS) to increase heart rate and the force of contraction of the heart?
- A. Norepinephrine
- B. Epinephrine
- C. Dopamine
- D. Acetylcholine
Correct answer: A
Rationale: The correct answer is Norepinephrine. Norepinephrine is the neurotransmitter released by the sympathetic nervous system that increases heart rate and the force of contraction. Epinephrine, though similar, is more involved in the fight-or-flight response and has a broader range of effects on various organs. Dopamine is not primarily responsible for increasing heart rate and contractility. Acetylcholine is a neurotransmitter that predominantly acts on the parasympathetic nervous system to decrease heart rate and contractility.
2. A client is taking Digoxin and has a new prescription for Colesevelam. Which of the following instructions should the nurse include in the teaching?
- A. Take digoxin with your morning dose of colesevelam.
- B. Your sodium and potassium levels will be monitored periodically while taking colesevelam.
- C. Watch for bleeding or bruising while taking colesevelam.
- D. Take colesevelam with food and at least one glass of water.
Correct answer: D
Rationale: When taking colesevelam, it should be administered with food and at least 8 oz of water to ensure proper absorption and reduce the risk of gastrointestinal side effects. Taking colesevelam with food also helps in binding to bile acids efficiently. Options A, B, and C are incorrect because they do not provide the necessary instruction for taking colesevelam correctly or monitoring specific side effects associated with this medication.
3. A healthcare professional is reviewing the laboratory results of a client who has rheumatoid arthritis. Which of the following findings should be reported to the provider?
- A. WBC count 8,000/mm3
- B. Platelets 150,000/mm3
- C. Aspartate aminotransferase 10 units/L
- D. Erythrocyte sedimentation rate 75 mm/hr
Correct answer: D
Rationale: The correct answer is D. A high erythrocyte sedimentation rate (ESR) of 75 mm/hr indicates inflammation, which is common in rheumatoid arthritis. Elevated ESR levels are often seen in inflammatory conditions like rheumatoid arthritis. Options A, B, and C are within the normal range and are not typically indicative of active inflammation associated with rheumatoid arthritis. Therefore, the nurse should report the elevated ESR level to the provider for further evaluation and management.
4. The nurse is preparing to administer medications to a client with osteoarthritis. What is the goal of medication therapy?
- A. Eradicate the disease
- B. Reduce pain and inflammation
- C. Turn on the immune system

Rationale:

- A. Preschool
- B. Young school age
- C. Middle school age
- D. Adolescent
