Correct Answer: D

Rationale: Withholding heparin IV infusion is the priority if there is a risk of complications such as bleeding, which must be evaluated before continuing treatment.

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: 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.

Correct Answer: C

Rationale: The correct answer is C: 'Rice with black beans.' Clients with hepatic encephalopathy should limit animal proteins due to their high ammonia content, which can exacerbate symptoms. Plant-based proteins like beans are preferred as they help reduce ammonia levels. Choices A, B, and D contain animal proteins that are not ideal for clients with hepatic encephalopathy.

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.
