Community Health HESI Practice Exam

Correct Answer: B

Rationale: Retinopathy of prematurity is the most common complication in premature infants exposed to high concentrations of oxygen. This condition leads to abnormal blood vessel growth in the retina, which can potentially result in blindness if not managed promptly. Intraventricular hemorrhage, though a significant concern in premature infants, is not directly related to oxygen therapy. Bronchopulmonary dysplasia is primarily associated with mechanical ventilation and oxygen exposure over time, not specifically with oxygen concentration monitoring. Necrotizing enterocolitis is more linked to gastrointestinal issues and is not the most common complication of oxygen therapy in premature newborns.

Correct Answer: A

Rationale: The correct answer is A: Individual, interpersonal, organizational, community, and policy. The social ecological model examines how individual, interpersonal, organizational, community, and policy factors interact to influence health and well-being. Choice B is incorrect because it includes genetic and biological factors that are not part of the social ecological model. Choice C is incorrect as it does not include organizational and policy levels of influence. Choice D is incorrect as it includes wealth and politics, which are not typically considered in the social ecological model.

Correct Answer: A

Rationale: The highest priority nursing intervention for a client with thrombophlebitis of the left leg is to elevate the leg on 2 pillows. Elevating the leg helps reduce swelling and pain associated with thrombophlebitis by promoting venous return. Applying support stockings (choice B) can be beneficial but is not the highest priority as elevation is more effective in the acute phase. Applying warm compresses (choice C) may worsen the condition by dilating the blood vessels, leading to increased pain and swelling. Maintaining complete bed rest (choice D) is important, but elevation takes precedence to improve circulation and reduce the risk of complications.

Correct Answer: B

Rationale: The correct answer is B. Occupational health nursing involves all aspects mentioned in the statements: prevention, recognition, treatment of injury and illness, application of nursing principles in conserving workers' health, and the requirement of special skills in health, education, and counseling. Choice A focuses on prevention, recognition, and treatment but does not encompass all aspects of occupational health nursing. Choice C only mentions the application of nursing principles without including prevention and treatment. Choice D specifically highlights the need for special skills but does not cover all the aspects of occupational health nursing.

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.
