Correct Answer: C

Rationale: The correct answer is C because effective teaching is demonstrated when the client can independently perform ostomy care. This indicates that the client has understood and retained the information provided during teaching. Choices A, B, and D are incorrect because demonstrating how to irrigate the colostomy, verbalizing understanding of dietary changes, and expressing feelings about the impact of the colostomy are important aspects of care but do not directly reflect the client's ability to apply the taught information in a practical setting.

Correct Answer: B

Rationale: The correct way to take buccal medications is to insert the tablet between the cheek and gums where it will dissolve slowly. Option A is incorrect because buccal medications are not meant to be dissolved in water. Option C is incorrect as sublingual medications are placed under the tongue. Option D is incorrect because chewing a buccal tablet is not the correct administration method.

Correct Answer: C

Rationale: The priority nursing intervention in this scenario is to contact the primary health care provider and discuss the possibility of simplifying the medication regimen. Simplifying the medication regimen is crucial for a client with early Alzheimer's disease to ensure they can manage their medications independently and safely. This intervention focuses on optimizing the client's ability to adhere to the prescribed medication schedule. Choices A and D involve external assistance and may not address the core issue of simplifying the regimen. Choice B, while helpful, does not directly address the need to simplify the regimen to enhance the client's medication management.

Correct Answer: A

Rationale: The correct answer is A. When a healthcare provider witnesses a client signing an informed consent form for surgery, they are affirming that the signature on the form belongs to the client. This is crucial for ensuring patient autonomy and informed decision-making. Choices B, C, and D are incorrect because while it is important for the client to understand the risks of surgery, be aware of postoperative care instructions, and have an opportunity to ask questions, these elements are not specifically affirmed by the healthcare provider witnessing the signature.

Correct Answer: A

Rationale: Choice A is the correct answer as nightmares about upcoming surgery indicate psychological distress commonly associated with fears, anxiety, and stress related to the treatment. Choices B, C, and D suggest positive emotions and proactive behaviors that are not typical signs of psychological distress in this context. Feeling more energetic, making future plans, and looking forward to treatment are generally positive indicators of coping and adjustment to the situation.
