Correct Answer: A

Rationale: The correct answer is A: 'Has increased airway obstruction.' High-pitched wheezes extending throughout exhalation indicate a worsening airway obstruction, leading to increased resistance in the airways. Low-pitched wheezes present on the final half of exhalation may suggest some level of obstruction, but the change to high-pitched wheezes throughout exhalation indicates a progression in the obstruction. Choice B is incorrect as the change in wheeze characteristics signifies deterioration rather than improvement. Choice C is incorrect as suctioning is not indicated based on the wheeze assessment findings. Choice D is incorrect as hyperventilation does not typically present with wheezes and is not supported by the information provided.

Correct Answer: A

Rationale: The correct answer is A. Providing nicotine replacement therapy is a key component of smoking cessation programs as it helps individuals manage nicotine withdrawal symptoms. Nicotine replacement therapy includes options like nicotine gum, patches, lozenges, or inhalers. Choice B, offering surgical interventions, is incorrect as smoking cessation programs primarily focus on behavioral and pharmacological interventions rather than surgical procedures. Choice C, conducting regular health screenings, is also incorrect as it is not a direct key component of smoking cessation programs. Choice D, promoting alcohol consumption, is not only incorrect but counterproductive, as it can be detrimental to overall health and hinder smoking cessation efforts.

Correct Answer: B

Rationale: Occupational health nursing focuses on educating workers about health, promoting health through appropriate and effective ways, and planning and administering health services in the workplace. Immediate diagnosis of illness prevailing in the work field is typically not the primary role of occupational health nursing, as it usually involves prevention, education, and health promotion rather than diagnosing acute conditions.

Correct Answer: A

Rationale: The correct answer is A: Assess community needs for health education. This is the initial step in developing a health education plan as it helps in understanding the specific requirements of the community. Identifying subjects for teaching (choice B) comes after assessing needs. Specifying goals and objectives (choice C) is crucial but typically follows the assessment of community needs. Identifying support providers and types (choice D) is important but is not the first step in preparing a health education plan.

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.
