Community Health HESI Practice Exam

Correct Answer: D

Rationale: The PPD (purified protein derivative) intradermal test is the standard screening method for detecting tuberculosis infection. It helps identify individuals who have been infected with Mycobacterium tuberculosis. A chest x-ray (Choice A) is used to assess the extent of active disease, not for screening purposes. Blood culture (Choice B) is not typically used for tuberculosis screening. Sputum culture (Choice C) is used to confirm active tuberculosis in symptomatic individuals, not for initial screening purposes.

Correct Answer: B

Rationale: PCA allows patients to self-administer pain medication within prescribed limits, without the need to call the nurse before taking an additional dose. Choice B suggests a misunderstanding of how PCA works, as the patient should be educated that they can self-administer doses within the safety parameters set by the healthcare provider. Choices A, C, and D demonstrate proper understanding of PCA, hence are not indicative of needing further teaching.

Correct Answer: D

Rationale: The correct answer is D, physical therapy. Tertiary prevention focuses on rehabilitation and treatment to prevent complications from a disease or injury. Physical therapy falls under this category as it helps individuals recover and improve functionality after an illness or injury. Choices A, B, and C are not examples of tertiary prevention. Health education (choice A) is more aligned with primary prevention by promoting healthy behaviors to prevent disease onset. Regular exercise (choice B) can be categorized under both primary and secondary prevention as it aims to prevent disease development and detect conditions early. Screening tests (choice C) are part of secondary prevention as they aim to detect diseases at an early stage for prompt treatment.

Correct Answer: B

Rationale: The correct answer is B: secondary prevention. Secondary prevention involves identifying and addressing issues early to prevent further harm. In this scenario, the nurse is intervening by discussing domestic violence prevention with the client who is showing signs of facial bruising, aiming to prevent further harm even though the client has not disclosed being battered. Choice A (primary prevention) focuses on preventing the onset of a problem before it occurs, like educating about healthy relationships before violence happens. Choice C (tertiary prevention) involves managing and treating the effects of a problem that has already occurred, such as providing counseling to a domestic violence survivor. Choice D (health promotion) aims to enhance well-being and prevent health problems through educational and environmental interventions, which may include aspects of preventing domestic violence, but in this case, the nurse's direct intervention is more about early identification and prevention of harm, aligning it with secondary prevention.

Correct Answer: D

Rationale: The correct answer is 'Parasitism as a health threat.' This choice accurately describes the ongoing issue of parasitic infections in the community, highlighting the seriousness and urgency of the problem. Choice A ('Parasitism as a foreseeable crisis') is incorrect as it does not emphasize the immediate danger posed by parasitic infections. Choice B ('Malnutrition as a health deficit') is not the most relevant diagnosis considering the context provided. Choice C ('Parasitism as a health deficit') is also incorrect as it fails to capture the level of risk and urgency associated with parasitic infections in this scenario.
