Community Health HESI Practice Questions

Correct Answer: B

Rationale: Prevalence is the correct answer as it refers to the number of existing cases of a disease in a specific population at a given time. Incidence, on the other hand, refers to the number of new cases of a disease in a defined population over a specific period. Mortality rate is the measure of the number of deaths in a particular population due to a specific cause, while morbidity rate is the frequency of a disease in a specific population.

Correct Answer: B

Rationale: The correct answer is to inspect the nares and ears for skin breakdown. This is important because the nasal cannula can cause skin breakdown due to prolonged use and friction. Ensuring that the skin is intact helps prevent complications. Choice A is incorrect as oxygen therapy via a nasal cannula does not involve mist. Choice C is incorrect as lubricating the tips of the cannula is not a standard practice and may lead to complications. Choice D is incorrect because while cleanliness is important, maintaining sterile technique is not necessary for handling a nasal cannula in this context.

Correct Answer: C

Rationale: The correct answer is C because wound care for a postoperative infection is a skilled service that qualifies for Medicare reimbursement. Choices A, B, and D involve assessments, teaching, and evaluation, which may not meet the criteria for Medicare reimbursement as they do not directly involve a skilled nursing service related to a postoperative condition.

Correct Answer: D

Rationale: Building a healthy community is indeed based on principles like concreteness, group dynamics, and focusing on community-level change. However, stating that environmental factors are more basic than institutional factors is incorrect. Both environmental and institutional factors play crucial roles in community health. Environmental factors like access to healthcare, clean water, and safe housing are vital, while institutional factors such as healthcare systems, education, and governance also significantly impact community health. Therefore, the correct answer is D, as environmental factors are not more basic than institutional factors.

Correct Answer: D

Rationale: Irregular hip symmetry, such as asymmetry in the gluteal folds, is a common sign of hip dislocation in newborns. This finding indicates a potential abnormality in hip development and requires further evaluation and possible treatment. Choices A, B, and C are incorrect. Flexion of lower extremities is a normal newborn reflex, the Ortolani response is used to detect hip dysplasia rather than hip dislocation, and a lengthened leg of the affected side is not typically associated with hip dislocation in newborns.
