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: The correct answer is 'Muscle weakness.' Hypokalemia is characterized by low potassium levels, which can lead to muscle weakness due to impaired muscle function. Choices A, B, and C are incorrect findings associated with other medical conditions and not typically expected in hypokalemia. Muscle stiffness is more commonly associated with conditions like tetany or muscle cramps, bradycardia is more commonly associated with issues like heart block or hypothyroidism, and hyperreflexia is more commonly seen in conditions like hyperthyroidism or spinal cord injuries.

Correct Answer: C

Rationale: The correct action for the nurse to take when caring for a client with a prescription for wound irrigation is to cleanse the wound from the center outwards. This technique helps prevent contamination by pushing debris away from the wound rather than into it. Choice A is incorrect because wearing sterile gloves is important during wound care but not specifically mentioned for wound irrigation. Choice B is incorrect because warming the irrigation solution to a specific temperature is not a standard recommendation and can potentially harm the client. Choice D is incorrect because the size of the syringe may vary based on the wound size and depth, so using a 20 mL syringe is not a universal guideline.

Correct Answer: B

Rationale: The nurse should clarify prescription B, Acetaminophen 650 mg PO BID, with the provider. When a patient is NPO and receiving enteral feedings through an NG tube, medications administered orally may be contraindicated due to the risk of aspiration. Therefore, Acetaminophen should be confirmed for safety in this situation. The other options (Metoprolol ER 50 mg via NG tube BID, Lisinopril 10 mg PO daily, Ondansetron 4 mg IV push PRN) are appropriate and do not need clarification in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Hypokalemia is an adverse effect of digoxin. Digoxin can cause hypokalemia, which increases the risk of toxicity. Monitoring potassium levels is crucial when a client is taking digoxin. Choices B, C, and D are incorrect as hypernatremia, hypertension, and tachycardia are not directly associated with digoxin use.
