Cardiovascular System Exam Questions
1. Which heart chamber receives oxygenated blood from the four pulmonary veins and serves as a reservoir during ventricular systole?
- A. Right atrium
- B. Left atrium
- C. Right ventricle
- D. Left ventricle
Correct answer: B
Rationale: The correct answer is B, Left atrium. The left atrium receives oxygenated blood from the lungs via the four pulmonary veins and acts as a holding chamber before the blood is pumped into the left ventricle. Choice A, Right atrium, is incorrect as it receives deoxygenated blood from the body via the vena cava. Choices C and D, Right ventricle and Left ventricle, are incorrect as they receive blood from the atria, not the pulmonary veins.
2. When teaching a client with schizophrenia strategies to cope with anticholinergic effects of Fluphenazine, which of the following should the nurse suggest to minimize anticholinergic effects?
- A. Take the medication in the morning to prevent insomnia.
- B. Chew sugarless gum to moisten the mouth.
- C. Use cooling measures to decrease fever.
- D. Take an antacid to relieve nausea.
Correct answer: B
Rationale: The correct answer is B: 'Chew sugarless gum to moisten the mouth.' Chewing sugarless gum can help alleviate dry mouth, which is a common anticholinergic effect of Fluphenazine. Dry mouth can be uncomfortable and affect the client's oral health. Options A, C, and D are incorrect because they do not directly address anticholinergic effects. Taking the medication in the morning to prevent insomnia (Option A) is unrelated to anticholinergic effects. Using cooling measures to decrease fever (Option C) is not a common anticholinergic effect of Fluphenazine. Taking an antacid to relieve nausea (Option D) does not specifically target anticholinergic effects.
3. In addition to antianxiety agents, which classification of drugs is commonly prescribed to treat anxiety and anxiety disorders?
- A. Antipsychotics
- B. Mood stabilizers
- C. Antidepressants
- D. Cholinesterase inhibitors
Correct answer: C
Rationale: Antidepressants, especially selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), are frequently used in the treatment of anxiety disorders. These medications help alleviate symptoms by affecting neurotransmitters in the brain associated with mood regulation and anxiety.
4. What are signs of hearing loss? (Select all that apply)
- A. Presence of cerumen

- B. If a nurse is found guilty of malpractice, the institution cannot sue the nurse.
- C. Liability policies may also cover charges of libel, slander, assault, and HIPAA violations.
- D. Only doctors are sued for malpractice.
Correct answer: C
Rationale: The correct answer is C. Liability policies can cover charges of libel, slander, assault, and HIPAA violations, in addition to malpractice claims. Choice A is incorrect as there are expenses involved in frivolous lawsuits. Choice B is incorrect because institutions can sue nurses found guilty of malpractice. Choice D is incorrect as nurses, not just doctors, can be sued for malpractice.
