Correct Answer: C

Rationale: The correct answer is C: aPTT 60 seconds. An aPTT of 60 seconds is above the therapeutic range for clients on heparin therapy and indicates a risk of bleeding, so it should be reported to the provider. INR of 2.0 is within the therapeutic range for clients on heparin therapy, so it does not require immediate reporting. Platelet count of 150,000/mm3 and WBC count of 8,000/mm3 are within normal ranges and not directly related to heparin therapy, so they do not need to be reported in this context.

Correct Answer: A

Rationale: The correct answer is to confirm the client's perception of the event. In crisis intervention, understanding the client's perspective is crucial as it helps the nurse assess the situation accurately and provide tailored support. This step can also help build rapport and trust with the client. Option B, notifying the client's support system, may be important but should come after assessing the client's perception. Option C, helping the client identify personal strengths, and option D, teaching relaxation techniques, are valuable interventions but should follow the initial step of confirming the client's perception.

Correct Answer: A

Rationale: The correct first action for the nurse to take when preparing to administer a unit of packed RBCs is to check the client's identification band. This step is crucial to ensure that the correct blood is administered to the right client, preventing any errors or adverse reactions. Verifying the provider's prescription, priming the IV tubing, and obtaining the client's vital signs are important steps in the process but should follow the initial identification check to prioritize patient safety.

Correct Answer: B

Rationale: The correct action for the nurse to take when caring for a client receiving total parenteral nutrition (TPN) is to change the TPN tubing every 24 hours. This practice helps reduce the risk of infection in clients receiving parenteral nutrition. Measuring the client's blood glucose level every 6 hours is important for clients on insulin therapy or with diabetes, but it is not directly related to TPN administration. Weighing the client weekly is essential for monitoring fluid status and nutritional progress, but it is not specific to TPN care. Administering TPN through a peripheral IV line is incorrect because TPN solutions are hypertonic and can cause phlebitis or thrombosis if administered through a peripheral line; a central venous access is typically used for TPN administration.

Correct Answer: B

Rationale: The correct answer is B: 'I will check my feet daily for any open sores or wounds.' This statement shows an understanding of the importance of foot care in preventing complications like diabetic foot ulcers. Monitoring blood glucose levels (choice A) is crucial but not directly related to foot care. Monitoring blood pressure (choice C) is important for overall health but does not specifically address preventing long-term complications of diabetes. Consuming foods high in fiber (choice D) is beneficial for managing blood sugar levels but does not directly address preventing foot complications.
