Correct Answer: C

Rationale: The correct answer is to advise the client to rise slowly from a sitting or lying position. Beta-blockers can cause bradycardia and hypotension, so clients should be advised to rise slowly to prevent dizziness and falls. Monitoring the client's heart rate and blood pressure regularly is essential. Instructing the client to avoid high-potassium foods (Choice A) is not directly related to beta-blockers. While monitoring the client's heart rate (Choice B) is important, advising the client to rise slowly (Choice C) is more directly related to potential side effects of beta-blockers. Instructing the client to avoid sudden position changes (Choice D) is not as specific or essential as advising them to rise slowly to prevent adverse effects.

Correct Answer: B

Rationale: Renting movies and borrowing books for use during recovery indicates the client is planning restful activities at home, which aligns with appropriate post-chemotherapy care. Choices A, C, and D are incorrect because refusing anti-nausea medication can lead to complications, resuming strenuous physical activity immediately can be harmful, and reporting severe fatigue and inability to perform daily activities may indicate a need for medical attention rather than understanding discharge care needs.

Correct Answer: B

Rationale: The correct action for the nurse to take is to continue obtaining client data to complete the fall risk survey. Even though the client reports never falling, it is essential to assess all fall risk factors comprehensively. Fall risk surveys provide valuable information on mobility, vision, medications, and other factors that can impact safety. Option A is incorrect because suggesting moving to an assisted living facility is premature without completing the fall risk assessment. Option C is incorrect as reducing the frequency of fall risk assessments could overlook potential risk factors. Option D is incorrect as the client's statement alone is not enough to confirm their safety living alone; a thorough assessment is necessary.

Correct Answer: C

Rationale: The correct answer is C. The second nurse should assist with compressions or breathing to ensure the patient receives adequate care during CPR. This immediate intervention is crucial in maintaining blood circulation and oxygenation to vital organs. Choice A is incorrect because simply relieving the nurse performing CPR may lead to a delay in essential life-saving measures. Choice B is incorrect as the primary focus should be on providing direct assistance rather than fetching equipment. Choice D is incorrect as validating the client's advanced directive is not the priority in this emergency situation.

Correct Answer: D

Rationale: The best reinforcement strategy in this scenario is providing preferred activities or tokens for compliance. Positive reinforcement is effective in behavior modification programs for individuals with intellectual disabilities. Offering preferred activities or tokens serves as a reward for completing the desired behavior, in this case, oral hygiene tasks. Choices A, B, and C do not focus on reinforcing the desired behavior with positive incentives. Choice A does not provide a positive reinforcement for compliance but rather focuses on the omission of a task. Choice B uses candy, which may not be ideal for oral hygiene. Choice C involves punishment rather than positive reinforcement.
