Correct Answer: B

Rationale: The most crucial instruction for the nurse to give a client with a UTI who is prescribed antibiotics is to complete the full course of antibiotics. Completing the full course of antibiotics is essential to ensure that the infection is fully treated and to prevent the development of antibiotic resistance. While taking antibiotics with food, increasing fluid intake, and managing discomfort with pain relievers are important aspects of UTI management, completing the prescribed course of antibiotics is the top priority to achieve the best treatment outcomes and prevent recurrence of the infection.

Correct Answer: D

Rationale: In this scenario, the best reinforcement for the nurse to implement is preferred activities or privileges for compliance. Positive reinforcement with privileges is effective in encouraging behavior change in adolescents, including those with intellectual disabilities. Choice A (Candy for successful oral hygiene tasks) may not be suitable as it involves providing a sugary reward, which contradicts the goal of oral hygiene. Choice B (Tokens for each successful oral hygiene task) could be effective but may not be as motivating as preferred activities or privileges. Choice C (Privilege restrictions for refusing oral hygiene tasks) focuses on negative reinforcement, which is not as effective as positive reinforcement in behavior modification.

Correct Answer: B

Rationale: The correct answer is B, Serum calcium. Numbness and tingling in the fingers and around the mouth are indicative of hypocalcemia, a condition characterized by low calcium levels in the blood. Reviewing the client's serum calcium levels is crucial in this situation to assess for hypocalcemia. Choice A, Capillary glucose, is incorrect because symptoms described are not typically associated with glucose abnormalities. Choice C, Urine specific gravity, and Choice D, White blood cell count, are unrelated to the symptoms presented and are not indicative of the client's condition.

Correct Answer: C

Rationale: The client with a newly fractured femur and soft wrist restraints should receive the most care hours as they have physical limitations due to the fracture and mental limitations due to being restrained. This client requires continuous monitoring, support, and frequent assessments to prevent complications. Choices A, B, and D do not have the same level of physical and mental care needs as the client with the newly fractured femur and soft wrist restraints.

Correct Answer: A

Rationale: The most appropriate intervention for the nurse to suggest to a 30-year-old male client experiencing difficulty sleeping due to anxiety about his upcoming surgery is to recommend taking a mild sedative before bed. A mild sedative can help manage anxiety and improve sleep in such situations. Encouraging physical activity before bedtime, advising to listen to calming music, or recommending reading a book may not directly address the client's anxiety and may not be as effective in promoting sleep in this scenario.
