Correct Answer: D

Rationale: To excel in a health education program, a Public Health Nurse (PHN) must possess a combination of teaching-learning strategies to effectively impart knowledge, provide accurate information to ensure credibility, and communicate ideas effectively to engage and interact with the audience. Therefore, all of these skills are essential for a PHN to succeed in her health education program. Choices A, B, and C are integral components of a successful health education program, making option D the correct answer.

Correct Answer: B

Rationale: The correct answer is B. Echolalia (repeating others' words) and a shuffling gait are common symptoms of Parkinson's disease. These symptoms result from the degeneration of the basal ganglia in the brain that controls movement and speech. Choice A is incorrect because non-intention tremors are not typically associated with Parkinson's disease. Choice C is incorrect as muscle spasm and a bent-over posture are not classic manifestations of Parkinson's disease. Choice D is incorrect since intention tremors and jerky movement of the elbows are not characteristic of Parkinson's disease.

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.

Correct Answer: D

Rationale: Building a healthy community is indeed based on principles like concreteness, group dynamics, and focusing on community-level change. However, stating that environmental factors are more basic than institutional factors is incorrect. Both environmental and institutional factors play crucial roles in community health. Environmental factors like access to healthcare, clean water, and safe housing are vital, while institutional factors such as healthcare systems, education, and governance also significantly impact community health. Therefore, the correct answer is D, as environmental factors are not more basic than institutional factors.

Correct Answer: C

Rationale: The correct answer is C: Tachycardia. Albuterol can cause tachycardia as a side effect due to its stimulant effect on the heart. It acts as a beta-2 adrenergic agonist, leading to increased heart rate. Hypoglycemia (choice A) is not a common side effect of albuterol. Hyperkalemia (choice B) is also not typically associated with albuterol use. Hypotension (choice D) is less likely to occur as albuterol usually causes tachycardia rather than hypotension.
