Community Health HESI Practice Exam

Correct Answer: C

Rationale: The correct answer is to wash and rinse the bed linens in hot water to help eliminate dust mites, a common trigger for asthma episodes. Washing in hot water is more effective in killing dust mites compared to warm water. Changing pillow covers every month may help but is not as effective as washing bed linens in hot water. Using air filters in the furnace system may improve air quality but does not directly target dust mites on bed linens.

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.

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.

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 most appropriate advice for an adolescent with acne is to eat a balanced diet for their age. A balanced diet that includes a variety of nutrients is essential for overall health, including skin health. While protein and Vitamin A are important for skin health, focusing solely on increasing these nutrients may not address the overall dietary needs. Similarly, solely decreasing fatty foods or avoiding caffeine may not be the most effective advice for managing acne. Therefore, the best advice is to promote a balanced diet tailored to the adolescent's age.
