Correct Answer: B

Rationale: The correct answer is B: Place the client in a 30-degree lateral position. Positioning the client laterally reduces pressure on bony prominences, improving circulation and helping prevent pressure injuries. Placing the client in a prone position (choice A) increases pressure on the bony prominences, raising the risk of pressure injuries. Similarly, placing the client in a high Fowler's position (choice D) can also increase pressure on certain areas. While encouraging the client to reposition every 4 hours (choice C) is important, the specific lateral positioning is more beneficial in preventing pressure injuries.

Correct Answer: B

Rationale: The correct answer is B: Assess the wound and reposition the patient frequently. When caring for a patient with a pressure ulcer, it is crucial for the nurse to assess the wound regularly to monitor its progress and prevent complications. Additionally, repositioning the patient frequently helps to relieve pressure on the affected area, prevent further damage, and promote healing. Choice A is incorrect because while cleaning the wound is important, applying a protective dressing is not the primary role of the nurse in managing a pressure ulcer. Choice C is incorrect as applying pressure to the ulcer is harmful, and monitoring for signs of healing should not involve applying pressure. Choice D is incorrect as providing pain relief and administering antibiotics may be necessary but are not the primary interventions for managing a pressure ulcer.

Correct Answer: D

Rationale: In the management of sepsis, prompt intervention is crucial. Administering IV antibiotics is essential to target the underlying infection. Monitoring blood pressure helps assess the patient's hemodynamic status. Administering fluids is vital to maintain adequate perfusion. Therefore, all the options are integral components of the initial management of sepsis, making 'All of the above' the correct answer. Choosing any single intervention over the others may delay optimal care and compromise patient outcomes.

Correct Answer: D

Rationale: The correct answer is D because it accurately transcribes the prescription by specifying the medication (Potassium chloride), the dose (20 mEq), the route (PO for by mouth), and the frequency (every morning). Choice A is incorrect as it specifies a lower dose compared to the correct prescription. Choice B is incorrect due to an inaccurate dose. Choice C is incorrect as it lacks specificity regarding the type of potassium prescribed and the dose.

Correct Answer: D

Rationale: The nurse should prioritize performing a wound culture before administering antibiotics to ensure appropriate treatment. This step helps identify the specific infecting organism and its susceptibility to different antibiotics, guiding effective antibiotic therapy. Changing the dressing daily (Choice A) is important but comes after assessing the infection and initiating appropriate treatment. Cleansing the wound with an antiseptic solution (Choice B) and applying a wet-to-dry dressing (Choice C) are interventions that may be necessary but are secondary to determining the most suitable antibiotic therapy based on the wound culture results.
