Community Health HESI Test Bank 2023

Correct Answer: C

Rationale: The primary function of a public health nurse is to promote and protect the health of populations. Public health nurses focus on preventing diseases, promoting healthy behaviors, and addressing health disparities within communities. Providing bedside care (choice A) is typically done by nurses in clinical settings, not public health nurses. Administering medications (choice B) is part of nursing practice but not the primary role of a public health nurse. Performing surgical procedures (choice D) is usually the responsibility of surgical nurses or healthcare providers specializing in surgery, not public health nurses.

Correct Answer: C

Rationale: The correct answer is C: Bulimia. Bulimia involves cycles of binge eating and purging, where individuals may induce vomiting or use laxatives and diuretics. These purging behaviors can lead to significant fluctuations in potassium levels due to electrolyte imbalances caused by excessive loss of potassium through vomiting and purging. In contrast, Binge eating disorder (A) does not involve purging behaviors, so it is less likely to cause significant potassium fluctuations. Anorexia nervosa (B) is characterized by severe food restriction rather than purging, leading to a different pattern of electrolyte imbalances. Purge syndrome (D) is not a recognized eating disorder and is not associated with specific patterns of potassium fluctuations seen in bulimia.

Correct Answer: A

Rationale: The correct answer is A. A 17-year-old who is sexually active with numerous partners is at the highest risk for contracting an HIV infection due to engaging in risky sexual behavior with multiple partners, increasing the likelihood of exposure to the virus. Choice B is less risky as the individual has had a relatively lower number of sexual partners in the past year. Choice C, although involving drug use, does not directly correlate with a higher risk of contracting HIV unless needles are shared. Choice D, a 34-year-old male homosexual in a monogamous relationship, has a lower risk compared to choice A as long as the relationship remains monogamous.

Correct Answer: B

Rationale: The correct answer is B: 'Morbidity.' Morbidity specifically refers to the statistics of illnesses, encompassing the incidence, prevalence, and duration of disease within a population. Choice A, 'Vital statistics,' typically refers to data on births, deaths, marriages, and divorces. Choice C, 'Statistics,' is a broad term encompassing the collection, analysis, interpretation, and presentation of numerical data. Choice D, 'Mortality,' specifically refers to the state of being subject to death or the number of deaths in a given population.
