Correct Answer: C

Rationale: Using an abduction pillow between the client's legs is essential in maintaining proper alignment and preventing dislocation of the hip joint following a hip arthroplasty. Encouraging the client to lie flat in bed (Choice A) is not recommended as early mobilization is crucial for preventing complications. Applying heat to the incision site (Choice B) is not typically done immediately postoperatively. Placing a trochanter roll under the client's knees (Choice D) is not as beneficial as using an abduction pillow to maintain proper positioning.

Correct Answer: A

Rationale: The correct action the nurse should take is to administer the medication over 60 minutes. This is important because administering vancomycin over 60 minutes helps prevent red man syndrome, a reaction that can occur with rapid infusion. Monitoring the client's blood glucose level (Choice B) is unrelated to vancomycin administration. Infusing the medication rapidly (Choice C) is incorrect and can lead to adverse reactions. Administering the medication using a filter needle (Choice D) is unnecessary for vancomycin administration.

Correct Answer: B

Rationale: The correct answer is to assist the client to the left Sims' position when administering an enema. This position helps facilitate the flow of the enema solution into the rectum. Placing the client in a high-Fowler's position (Choice A) is not ideal for administering an enema. Inserting the enema tubing 2.5 cm (1 in) into the rectum (Choice C) is incorrect as it should be inserted 7.5-10 cm (3-4 in) for an adult. Lubricating the tip of the enema tubing with petroleum jelly (Choice D) is a correct step to ease insertion but is not the most critical action among the choices provided.

Correct Answer: C

Rationale: Obtaining a prescription for restraint within 4 hours is the correct action when managing restraints in a client with acute mania. This timeframe ensures that the use of restraints is promptly evaluated and authorized by a healthcare provider. Requesting a renewal of the prescription every 8 hours (Choice A) is not necessary and may delay appropriate care. Checking the client's peripheral pulse rate every 30 minutes (Choice B) is important but not the immediate priority when dealing with obtaining a prescription for restraints. Documenting the client's condition every 15 minutes (Choice D) is essential for monitoring, but the priority is to secure a prescription for restraints promptly.

Correct Answer: C

Rationale: The correct answer is C: 'Choose foods low in trans fats.' Trans fats are known to increase cholesterol levels, so avoiding foods high in trans fats is essential in managing hypercholesterolemia. Option A, increasing intake of red meat, and option B, consuming foods high in saturated fats, can worsen cholesterol levels as they are sources of unhealthy fats. Option D, limiting intake of vegetables and fruits, is incorrect as they are part of a heart-healthy diet and should be encouraged for individuals with hypercholesterolemia.
