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: Referring the student for further evaluation of scoliosis is crucial to confirm the diagnosis and determine the appropriate management plan. Sending the student home (choice A) without proper assessment and intervention is not the best course of action. Withdrawing the student from all physical activities (choice C) is not necessary and may cause unnecessary distress. Instructing the student not to carry her backpack on her back (choice D) does not address the underlying issue of scoliosis and is not the most important intervention at this point.

Correct Answer: C

Rationale: The correct answer is C: Measles, mumps, rubella (MMR). MMR vaccine is commonly included in precollege physicals to ensure students are protected against these diseases. Choice A, Hepatitis C (HepC), is incorrect as the standard vaccine for hepatitis given in childhood is Hepatitis B. Choice B, Influenza type B (HIB), is not typically administered during precollege physicals but is recommended for younger children. Choice D, Diphtheria, tetanus, pertussis (DTaP), is usually given in early childhood and not typically repeated during precollege physicals.

Correct Answer: C

Rationale: In this scenario, requesting mayors to create a task force is the most effective strategy to improve environmental health conditions in the community. Engaging with local government officials ensures the allocation of resources, coordination of efforts, and the implementation of sustainable solutions. While meeting with youth officials, parents' group leaders, religious and educational leaders are important, involving mayors in creating a task force will lead to broader community involvement and support. Informing local announcers about the project, although helpful for awareness, is not as impactful as engaging with local authorities for tangible change.

Correct Answer: D

Rationale: The correct first action for the nurse to take when identifying what appears to be ventricular tachycardia in a client being evaluated for possible myocardial infarction is to assess the client's airway, breathing, and circulation. This step is crucial to determine the client's stability and the need for immediate intervention. Beginning cardiopulmonary resuscitation or preparing for immediate defibrillation without first assessing the airway, breathing, and circulation could delay potentially life-saving interventions. Notifying the 'Code' team and healthcare provider should come after ensuring the client's immediate needs are addressed.
