Correct Answer: B

Rationale: Placing a pillow between the client's legs when turning is essential to prevent hip dislocation post hip replacement surgery. This action helps maintain proper alignment of the hip joint and prevents adduction, which can lead to dislocation. Positioning the client's legs in adduction (choice A) can increase the risk of hip dislocation. Keeping the client in a low Fowler's position (choice C) or turning the client onto the affected side (choice D) does not directly address hip dislocation prevention.

Correct Answer: A

Rationale: Corrected Rationale: Providing information about stress management is essential when caring for a client with Raynaud's disease because stress can trigger episodes. Stress management techniques can help the client avoid triggers and reduce the frequency of episodes. Choice B is incorrect because maintaining a warm temperature, rather than a cool one, helps prevent vasoconstriction and can be beneficial for clients with Raynaud's disease. Choice C is incorrect because epinephrine is not a standard treatment for Raynaud's disease; it is more commonly used for severe allergic reactions. Choice D is incorrect because glucocorticoid steroids are not typically used in the management of Raynaud's disease.

Correct Answer: B

Rationale: The correct answer is B: Start the transfusion with 0.9% sodium chloride. 0.9% sodium chloride is the only IV solution that is compatible with blood products and should be used to prime the tubing before a transfusion. Choice A is incorrect because vital signs should be monitored more frequently, typically every 15 minutes at the beginning of the transfusion. Choice C is incorrect as blood transfusions are usually administered over 2-4 hours, not 6 hours. Choice D is incorrect as the first 500 mL of blood should be infused slowly over 1-2 hours to monitor for any adverse reactions.

Correct Answer: C

Rationale: The correct action for the nurse to take is to ensure that the newborn wears a diaper. This is important to prevent skin irritation during phototherapy. Choice A is incorrect as newborns should be breastfed or formula-fed, not given glucose water. Choice B is unnecessary and may interfere with the effectiveness of phototherapy. Choice D is inappropriate as lotions can interfere with the phototherapy and increase the risk of skin damage.

Correct Answer: D

Rationale: A WBC count of 15,000/mm3 is elevated, which may indicate infection, a common concern postoperatively. An elevated WBC count suggests the body is fighting an infection, and prompt reporting to the provider is essential for further evaluation and treatment. Serosanguineous drainage on the surgical dressing is expected in the immediate postoperative period, respiratory rate of 16/min is within the normal range, and a heart rate of 90/min is also within an acceptable range postoperatively. Therefore, these findings do not raise immediate concerns that necessitate reporting to the provider.
