Community Health HESI Practice Exam

Correct Answer: B

Rationale: The correct answer is B: Anemia. Zidovudine (Retrovir) can cause bone marrow suppression, leading to anemia. Monitoring for signs of anemia, such as fatigue, pallor, and shortness of breath, is crucial. Choice A, Hyperglycemia, is not a common adverse effect of zidovudine. Choice C, Hypertension, is not directly associated with zidovudine use. Choice D, Hypercalcemia, is also not a typical adverse effect of zidovudine.

Correct Answer: B

Rationale: Epidemiology is the study of the distribution and determinants of health-related states in populations. Choice A is incorrect because epidemiology focuses on more than just causes but also on distribution and determinants. Choice C is incorrect as it specifically relates to public health and not just treatment and prevention. Choice D is incorrect as epidemiology is broader than just focusing on the healthcare system and its effectiveness.

Correct Answer: A

Rationale: Bradycardia (abnormally slow heart rate) is a key sign of digoxin toxicity. In this scenario, the child's symptoms of irritability, vomiting, along with the resting pulse of 78 despite being on digoxin, suggest an impending bradycardia due to digoxin toxicity. Lethargy can also be a sign, but in this case, the child is irritable rather than lethargic. Vomiting, though a symptom, is not as specific to digoxin toxicity as bradycardia. Irritability, while present, is not the most indicative finding of digoxin toxicity compared to bradycardia.

Correct Answer: B

Rationale: The correct answer is B: Anemia. Zidovudine (Retrovir) can cause bone marrow suppression, leading to anemia. Monitoring for signs of anemia, such as fatigue, pallor, and shortness of breath, is crucial. Choice A, Hyperglycemia, is not a common adverse effect of zidovudine. Choice C, Hypertension, is not directly associated with zidovudine use. Choice D, Hypercalcemia, is also not a typical adverse effect of zidovudine.

Correct Answer: D

Rationale: The correct answer is 'D' because all the listed factors - cigarette smoking, a parent with adult-onset diabetes, and exposure to toxic substances in the workplace - can individually influence a person's health status. Cigarette smoking directly impacts health by increasing the risk of various diseases. Having a parent with adult-onset diabetes can also influence one's health due to genetic predisposition and lifestyle factors. Exposure to toxic substances in the workplace can lead to health issues. Choices A, B, and C are not mutually exclusive but rather represent different aspects of individual influences on health status, making 'D' the most comprehensive and accurate answer.
