A nurse is caring for a client who has had an allogeneic hematopoietic stem-cell transplant. Which of the following infection-control precautions should the nurse use while caring for this client?

A) The client's hand is cool and pale: A cool and pale hand suggests decreased circulation, which could be due to the restraint being too tight and impeding blood flow. Loosening the restraint can improve circulation and prevent complications such as tissue damage or nerve injury.
B) The client has full range of motion in her wrist: While it's important to ensure that the client can move comfortably within the restraint to prevent stiffness and maintain circulation, full range of motion alone may not necessitate loosening the restraint. However, if the client's movements are restricted or uncomfortable due to the tightness of the restraint, loosening may be necessary.
C) The client is attempting to remove the restraint: This indicates that the restraint may be too loose or improperly applied, allowing the client to manipulate it easily. The nurse should assess the fit of the restraint and adjust it as needed to prevent the client from removing it while still ensuring safety and appropriate immobilization.
D) The client has a capillary refill of less than 2 seconds: While a rapid capillary refill indicates good circulation, it alone may not warrant loosening the restraint. However, if the client experiences discomfort or other signs of impaired circulation despite rapid capillary refill, the restraint may need adjustment to alleviate pressure and improve circulation.

A) "It's a good idea to help make sure your husband can sleep comfortably.":
This encourages the partner to administer medication, which can lead to overmedication and potential harm.

B) "Why do you think your husband needs more medication when he is asleep?":
This might cause the partner to feel defensive. It also does not provide the necessary education about the correct use of the PCA pump.

C) "Next time you think he needs more medication, call me and I'll push the button.":
This is inappropriate as well. It does not address the core issue that only the patient should be pressing the button to ensure safe and appropriate use of the PCA pump.

D) "Your husband should decide when more medication is needed.":
This educates the partner about the proper use of the PCA pump, emphasizing that only the patient should press the button to ensure they are receiving medication only when they feel pain. This minimizes the risk of overmedication and adverse effects.
