A nurse is caring for a client who is receiving a continuous heparin infusion. Which of the following laboratory tests should the nurse review prior to adjusting the client's heparin?

Explore the client's reasons for refusing the treatment.

• A. Documenting the client's refusal in the medical record is an important action, but not the first one. The nurse should first try to understand the client's perspective and address any concerns or misconceptions they might have about the blood transfusion. This choice is incorrect.
• B. Honoring the client's decision to refuse the blood transfusion is a respectful and ethical action, but not the first one. The nurse should first attempt to educate and persuade the client about the benefits and risks of the treatment, and respect their autonomy only after ensuring that they have made an informed decision. This choice is incorrect.
• C. Exploring the client's reasons for refusing the treatment is the first action that the nurse should take. The nurse should use effective communication skills to elicit the client's beliefs, values, fears, and preferences regarding the blood transfusion, and provide factual and evidencebased information to address any knowledge gaps or misconceptions. The nurse should also assess the client's decision-making capacity and determine if they are competent to refuse the treatment. This choice is correct.
• D. Discussing the client's refusal with the provider is an appropriate action, but not the first one. The nurse should first try to resolve the issue with the client directly, and involve the provider only if they are unable to do so or if there are legal or ethical implications that require further consultation. This choice is incorrect.

- A. Correct. The nurse should turn off the CPM machine during mealtime, as it can interfere with the client's ability to eat and drink comfortably. The nurse should also turn off the CPM machine when transferring or repositioning the client, or when performing wound care or other interventions on the affected leg.

- B. Incorrect. The nurse should maintain the client's affected hip in a neutral position, as external rotation can cause malalignment of the prosthesis and impair healing. The nurse should use pillows or wedges to support the leg and prevent rotation or abduction of the hip joint.

- C. Incorrect. The nurse should not instruct the client how to adjust the CPM settings, as this can compromise the prescribed range of motion and speed of the device. The nurse should follow the provider's orders and check with them before making any changes to the CPM settings. The nurse should also monitor the client's pain level and administer analgesics as needed to facilitate compliance with the therapy.

- D. Incorrect. The nurse should not store the CPM machine under the client's bed when not in use, as this can pose a safety hazard and damage the equipment. The nurse should place the CPM machine on a stable surface near the bed and ensure that it is plugged into a grounded outlet and has adequate battery backup in case of power failure.
