Correct Answer: C

Rationale: The correct answer is C. A1c is a key indicator of long-term diabetes management, reflecting average blood sugar levels over the past 2-3 months. Achieving a target A1c of 5% indicates good control of blood sugar levels and reduces the risk of diabetes-related complications. Choices A, B, and D are not as appropriate as they focus on short-term tasks or individual blood glucose readings, rather than long-term management and outcomes.

Correct Answer: B

Rationale: The correct answer is to wear a dosimeter film badge while in the client's room. This is crucial for monitoring radiation exposure levels when caring for a client with a sealed radiation implant. Option A is incorrect as removing dirty linens after double bagging them is not directly related to radiation safety. Option C is incorrect as there is no specific guideline to limit visitors to 1 hour per day for clients with sealed radiation implants. Option D is incorrect as the distance of family members from the client is not a primary safety measure when dealing with sealed radiation implants.

Correct Answer: B

Rationale: The nurse should question the prescription to apply heat to the affected extremity for 45 minutes. Heat should not be applied in the first 48 hours after an acute injury, as it can increase swelling. Cold therapy is more appropriate initially. Choices A, C, and D are appropriate actions in the care of a client with a sprained ankle. Elevating the affected extremity helps reduce swelling, wrapping it with a compression dressing provides support, and assessing sensation, movement, and pulse every 4 hours is important to monitor for complications.

Correct Answer: D

Rationale: When caring for a client with a C. difficile infection, it is essential to isolate them in a private room to prevent the spread of spores through contact with surfaces. Placing the client in a negative pressure room (Choice A) is not necessary for C. difficile. Using alcohol-based hand rub (Choice B) and wearing a face shield (Choice C) are important infection control measures but are not specific to the isolation requirements for C. difficile.

Correct Answer: D

Rationale: An absolute neutrophil count of 75/mm³ is critically low and places the client at high risk for infection, necessitating immediate intervention. Neutropenia increases susceptibility to infections, making it essential to report this finding promptly. The other options, such as pain level in pleurisy, drainage amount from a drain, and heart rate postoperatively, are important but do not indicate an immediate life-threatening condition that requires urgent provider notification.
