Community Health HESI Practice Questions

Correct Answer: D

Rationale: The correct answer is D: Elevated creatinine phosphokinase (CPK). Elevated CPK levels indicate muscle damage, including damage to the cardiac muscle, which aligns with the diagnosis of myocardial infarction. Choice A, low serum albumin, is not directly related to myocardial infarction. Choice B, high serum cholesterol, is more associated with conditions like atherosclerosis rather than acute myocardial infarction. Choice C, abnormally low white blood cell count, is typically not a lab value associated with myocardial infarction; instead, it could suggest other conditions like infections or bone marrow issues.

Correct Answer: B

Rationale: The correct answer is B: "Reduce acid secretion." Vagotomy is performed to reduce acid secretion by cutting the vagus nerve, which stimulates acid production. Choices A, C, and D are incorrect. A vagotomy does not increase acid secretion, promote gastric emptying, or remove the ulcerated area. It specifically aims to decrease acid production to help in the healing of peptic ulcers.

Correct Answer: D

Rationale: To accurately assess the health and social status of a community, conducting a community health survey is essential. This method provides a comprehensive and systematic way to gather data on various health indicators and social determinants within the community. Choices A, B, and C are not as effective in providing a holistic view of the community's health and social status. A mass information campaign may raise awareness but lacks in-depth data collection, a home visit focuses on individual households rather than the entire community, and a community assembly may not reach all community members or provide structured data collection.

Correct Answer: C

Rationale: The correct answer is C: 'Dyspnea and cough.' Pulmonary embolism often presents with a sudden onset of dyspnea (difficulty breathing) and cough, which are due to the obstruction of blood flow in the pulmonary arteries. Choices A, B, and D are incorrect. Positive Homan's sign is associated with deep vein thrombosis, fever and chills are nonspecific symptoms commonly seen in infective endocarditis, and sensory impairment is not typically indicative of pulmonary embolism.

Correct Answer: D

Rationale: The correct answer is D: 4-6 years of age. The CDC recommends administering the MMR booster to children aged 4 to 6 years. This booster dose is essential to ensure continued immunity against measles, mumps, and rubella. Choices A, B, and C are incorrect because they do not align with the CDC guidelines for the age range of MMR booster administration.
