Community Health HESI Practice Exam

Correct Answer: D

Rationale: The correct answer is D: Prolonged expiratory phase. In COPD, there is airflow obstruction leading to difficulty in exhaling air. This results in a prolonged expiratory phase. Choices A, B, and C are incorrect. Decreased anteroposterior diameter is associated with conditions like barrel chest in emphysema, not COPD. Hyperresonance on percussion is typical in conditions like emphysema, not necessarily in COPD. Increased breath sounds are not a typical finding in COPD; instead, diminished breath sounds may be present due to air trapping.

Correct Answer: B

Rationale: The continuum health model emphasizes ongoing health practices based on past behaviors. Choice A is incorrect as it describes a more binary approach to health. Choice C is incorrect as it focuses on alternative therapies rather than the continuity of health practices.

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: B

Rationale: Community health nursing primarily focuses on preventive measures and promoting overall health within a community. Choice A is incorrect as treatment is not the main emphasis. Choice C is incorrect as identification and assessment are steps that may be involved but not the main focus. Choice D is incorrect as it refers to the illness end rather than the preventive end of the wellness-illness continuum.

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.
