Correct Answer: C

Rationale: The correct answer is C. A magnesium level of 1.6 mEq/L is within the normal range, but monitoring potassium levels is crucial for clients taking furosemide. Furosemide can cause hypokalemia (low potassium levels), which can lead to adverse effects such as cardiac dysrhythmias. Sodium and calcium levels are not typically affected by furosemide, so they are not the priority findings to report to the provider in this case.

Correct Answer: A

Rationale: When managing care for a patient with a wound infection, administering prescribed antibiotics is crucial. Antibiotics are necessary to treat the infection and prevent it from worsening. While cleaning the wound with saline and applying a sterile dressing are important components of wound care, the primary treatment for a wound infection is antibiotics. Monitoring for signs of sepsis is also essential, but administering antibiotics promptly is the most critical step in managing a wound infection.

Correct Answer: A

Rationale: The correct answer is A: Immobility and poor nutrition are significant risk factors for pressure ulcers. Immobility leads to prolonged pressure on certain body areas, increasing the risk of tissue damage. Poor nutrition can impair skin integrity and the body's ability to heal. Prevention strategies include frequent turning and repositioning to relieve pressure points. Choice B is incorrect because increased mobility actually reduces the risk of pressure ulcers. Choice C is incorrect as excess moisture can contribute to skin breakdown, but it is not a primary risk factor. Choice D is incorrect as frequent turning and repositioning are part of the prevention measures, not risk factors.

Correct Answer: C

Rationale: The correct intervention for a client at risk for pressure ulcers is to turn and reposition the client every 2 hours. This helps relieve pressure on bony prominences, improving circulation and reducing the risk of pressure ulcer development. Applying heat to the affected area (Choice A) can increase the risk of skin breakdown. Placing the client in a prone position (Choice B) can also increase pressure on certain areas, leading to pressure ulcers. Providing the client with a bedpan every 4 hours (Choice D) is not directly related to preventing pressure ulcers.

Correct Answer: B

Rationale: Maintaining optimal function within the client's limitations is the most realistic and appropriate nursing goal when caring for an 80-year-old client with Parkinson's disease. This goal focuses on maximizing the client's abilities and quality of life while acknowledging the impact of the disease. Option A is less realistic as returning to usual activities may not always be achievable in the case of Parkinson's disease. Option C is not appropriate as it does not address the client's current condition and care needs. Option D is less realistic as Parkinson's disease is progressive, and delaying its progression may not be entirely feasible.
