Community Health HESI Exam

Correct Answer: A

Rationale: The correct answer is A: International Classification of Diseases. The ICD is a system used worldwide to classify and code various health conditions and diseases. This system helps in standardizing the documentation and coding of diseases, which is essential for epidemiology, research, and healthcare management. Choices B, C, and D are incorrect as they do not represent the widely recognized meaning of the acronym ICD in medical terminology.

Correct Answer: A

Rationale: The correct information that the nurse should provide to the group is that anthrax infection occurs when spores enter a host. Choice B is incorrect because mature anthrax bacteria do not live dormant on inanimate objects. Choice C is incorrect because anthrax spores can survive for extended periods outside of a living host. Choice D is incorrect because anthrax is not transmitted by respiratory droplets from person to person; it is acquired through spores entering a host.

Correct Answer: A

Rationale: The correct answer is A: Hypertension. Erythropoietin can lead to hypertension as a side effect due to its stimulation of red blood cell production, which can increase blood viscosity. This can result in elevated blood pressure. Choices B, C, and D are incorrect. Hypoglycemia is not a common side effect of erythropoietin. Hyperkalemia is more commonly associated with renal failure rather than erythropoietin use. Hypocalcemia is not a typical side effect of erythropoietin administration.

Correct Answer: D

Rationale: The best strategy for the nurse to use when teaching insulin injection techniques to a newly diagnosed client with diabetes is to observe a return demonstration. This method ensures that the client can correctly perform the technique. Providing written pre and post tests (choice A) may assess knowledge but not application. Asking questions during practice (choice B) may help with understanding but not necessarily with the actual performance. Allowing another diabetic to assist (choice C) may provide peer support but does not guarantee correct technique demonstration.

Correct Answer: D

Rationale: The correct answer is D, incidence rate. Incidence rate measures the frequency of new cases of a phenomenon, providing important information about the risk of developing the condition. Prevalence rate (choice A) reflects both old and new cases, proportionate mortality rate (choice B) is the proportion of deaths due to a specific cause, and case fatality rate (choice C) measures the proportion of deaths among confirmed cases, not just new cases.
