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.

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: Prothrombin time (PT) measures the time it takes for blood to clot and is a critical indicator of bleeding risk in clients with liver dysfunction. Impaired liver function reduces clotting factor production, leading to an increased PT, which requires close monitoring. Monitoring BUN (Choice A) is more indicative of kidney function, not clotting ability. Aspartate aminotransferase (AST) (Choice C) and serum albumin (Choice D) are important indicators of liver function, but they do not directly assess the client's bleeding risk.

Correct Answer: D

Rationale: In this scenario, the best care assignment for the client with a skin tear and hematoma is to supervise a nursing assistant for skin care. This ensures proper wound care while utilizing the skills of the nursing assistant effectively. Assigning an RN to supervise the nursing assistant is appropriate as it provides the necessary expertise for wound care supervision. Delegating complete care to an unlicensed assistive personnel may not be suitable for a client with specific wound care needs. Helping the client with self-care activities may not directly address the urgent need for proper wound care in this situation.

Correct Answer: A

Rationale: The correct answer is A: 83. The pharmacy provided the infusion at 10 million units per liter, which requires a rate of 83 mL/hour. To calculate this, multiply the dosage by the volume of the IV solution and divide by the concentration of the IV solution in million units: 10 million units per liter x 8.3 L = 83 mL/hour. Choices B, C, and D are incorrect as they do not align with the calculation based on the given information.
