Community Health HESI Exam
1. What title should be given to this occupational health nurse job description? A registered nurse who functions in a comprehensive executive role to set goals, formulate policy, and direct and evaluate the health service.
- A. manager
- B. researcher
- C. health educator
- D. health promotion specialist
Correct answer: A
Rationale: The correct answer is 'manager.' In the job description provided, the role involves setting goals, formulating policy, and directing and evaluating health services, which aligns with the responsibilities of a manager. A 'researcher' primarily focuses on conducting research, a 'health educator' specializes in educating individuals about health-related topics, and a 'health promotion specialist' concentrates on promoting health and wellness initiatives. Therefore, 'manager' is the most suitable title for the described role.
2. A client is receiving heparin to treat a deep vein thrombosis. The nurse should monitor which laboratory result to assist in evaluating the efficacy of the drug?
- A. Platelet count
- B. Prothrombin time
- C. Partial thromboplastin time
- D. Serum levels of protamine sulfate
Correct answer: C
Rationale: The nurse should monitor the partial thromboplastin time to evaluate the efficacy of heparin. Partial thromboplastin time reflects the anticoagulant effect of heparin by measuring the intrinsic pathway of coagulation. Platelet count assesses platelet levels and is not specific to heparin efficacy. Prothrombin time is used to monitor warfarin therapy. Serum levels of protamine sulfate are not used to evaluate the efficacy of heparin.
3. A client with a urinary tract infection is prescribed antibiotics. What should the nurse inform the client about antibiotic therapy?
- A. It may interfere with oral contraceptive effectiveness
- B. It can cause drowsiness
- C. It should be taken with meals
- D. Completing the full course is crucial
Correct answer: D
Rationale: Completing the full course of antibiotics is crucial to fully eradicate the infection and prevent the development of antibiotic resistance. Informing the client about the importance of finishing the prescribed course helps in ensuring the effectiveness of the treatment and reduces the risk of recurrence. Choice A is incorrect because antibiotics do not generally interfere with oral contraceptive effectiveness. Choice B is incorrect because drowsiness is not a common side effect of antibiotics. Choice C is incorrect because while some antibiotics may need to be taken with meals, it is not a universal rule for all antibiotics.
4. A nurse enters a client's room and finds her on the floor. The client's roommate reports that the client fell out of bed. Which of the following statements should the nurse document?
- A. “Client found lying on the floor.”
- B. “Client fell out of bed and was found on the floor.”
- C. “Client experienced a fall from the bed.”
- D. “Client was discovered on the floor following a fall from the bed.”
Correct answer: B
Rationale: The correct answer is B. The documentation should be clear and precise, providing details about the context of the fall. Choice A is vague and does not specify the cause of the client being on the floor. Choice C is less specific and does not directly state that the client fell from the bed. Choice D is wordy and less direct compared to option B, which clearly states that the client fell out of bed and was found on the floor.
5. Dizygotic (DZ) twins share _________ percent of their genes.
- A. 100
- B. 75
- C. 50
- D. 25
Correct answer: C
Rationale: Dizygotic (DZ) twins share approximately 50% of their genes. This is because dizygotic twins, also known as fraternal twins, originate from two separate fertilized eggs and share similar genetic similarity to regular siblings. Choice A (100%) is incorrect because if twins shared 100% of their genes, they would be identical twins (monozygotic). Choice B (75%) is incorrect as it is not the typical genetic similarity seen in dizygotic twins. Choice D (25%) is incorrect as it represents a significantly lower genetic similarity than what is observed in dizygotic twins.
