Correct Answer: A

Rationale: Assessing the client's perineum is the priority nursing action in this situation. By checking the perineum, the nurse can evaluate for skin damage, irritation, infection, or other issues that may be causing the client's pain. This assessment is crucial to determine the appropriate interventions needed to address the client's discomfort and prevent complications. Administering pain medication, cleaning the area with a mild cleanser, or applying a barrier cream are important interventions but should follow the initial assessment of the perineum to ensure comprehensive care and effective management of the client's condition. Prioritizing assessment allows for a targeted and individualized approach to care, enhancing the client's overall well-being.

Correct Answer: A

Rationale: Practice sessions are an effective psychomotor approach to learning for adolescents with ostomies as they involve hands-on practice of ostomy care skills, which can help reinforce learning through active engagement. Demonstrations (choice B) can be helpful in providing visual guidance but may not offer the same level of active participation and practice as practice sessions. Written instructions (choice C) may be useful for reference but may not be as effective in developing psychomotor skills. Group discussions (choice D) focus more on verbal exchange and may not directly address the need for hands-on skill development required in managing ostomies. Therefore, practice sessions are the most suitable method for enhancing psychomotor learning in this scenario.

Correct Answer: C

Rationale: The nurse should reassure the mother that the child's behavior is normal for their age and situation.

Correct Answer: D

Rationale: The correct answer is to proceed with the triage process in the same manner as any adult client. In this scenario, since the teenager is legally married, they have the legal authority to consent to their own treatment. Choice A is incorrect because the teenager, being legally married, can provide their own consent. Choice B is incorrect as it unnecessarily delays treatment by waiting for telephone consent from the partner, which is not required in this case. Choice C is incorrect as the teenager can receive appropriate care in the current emergency department setting without the need for referral.

Correct Answer: B

Rationale: In this scenario, the nurse should adjust the machine settings. If the electronic blood pressure machine is providing varied intervals and inconsistent readings, it indicates a potential malfunction. Changing the settings may help correct the issue and ensure accurate measurements. Discontinuing the machine and measuring manually every 15 minutes (Choice A) may be time-consuming and impractical. Cleaning the machine (Choice C) is important for routine maintenance but may not address the current issue of varied intervals and inconsistent readings. Increasing the frequency of the readings (Choice D) does not address the problem of inaccurate measurements caused by the malfunctioning machine.
