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: Stop smoking. Smoking causes vasoconstriction, worsening the symptoms of Raynaud's phenomenon. Quitting smoking is crucial in managing this condition effectively. Choices B, C, and D are not as directly related to the pathophysiology of Raynaud's phenomenon. While keeping feet dry and reducing stress can be beneficial for overall health, they are not as directly linked to managing Raynaud's phenomenon as smoking cessation.

Correct Answer: C

Rationale: Thinning of the skin with loss of elasticity is the physical characteristic of aging that contributes to an increased risk of developing decubitus ulcers. As individuals age, the skin becomes thinner and loses its elasticity, making it more susceptible to damage from pressure, leading to the formation of pressure ulcers. Choices A, B, and D are incorrect as they do not directly contribute to the development of decubitus ulcers in this context.

Correct Answer: B

Rationale: In the context of the PHC approach, programs should be characterized by being managed by community leaders/members (Choice A). This ensures community involvement and ownership. Programs should also be compatible with available resources (Choice C) to be sustainable and effective. Additionally, programs should be developmental in nature (Choice D), focusing on long-term improvements. Choice B is incorrect because programs should not be solely managed by non-government organizations; instead, they should be driven by the community to promote sustainability and empowerment.

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.
