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) Irritable: Irritability is more closely associated with emotional responses to stress rather than cognitive responses. While irritability can be a manifestation of stress, it primarily reflects emotional tension rather than cognitive impairment.

B) Lethargic: Lethargy is a physical response to stress rather than a cognitive one. It refers to a lack of energy, motivation, or enthusiasm, which can result from stress-induced fatigue or exhaustion.

C) Angry: Anger is also primarily an emotional response to stress rather than a cognitive one. While stress can contribute to feelings of anger or frustration, it does not directly reflect cognitive impairment or alterations in cognitive functioning.

D) Decreased attention to detail: Cognitive responses to stress can include difficulty concentrating, decreased attention to detail, memory problems, and impaired decision-making. When a client demonstrates decreased attention to detail, it indicates cognitive impairment or distraction, which can be a response to stress. This behavior suggests that the client's cognitive functioning is affected by the stress they are experiencing.

A. Raise the bed to a comfortable height:
Raising the bed to a comfortable height is essential for proper body mechanics and preventing back strain. It ensures the nurse can perform the procedure efficiently and safely.

B. Stand on the left side of the bed:
While a left-handed nurse might prefer to stand on the left side for better access, this choice depends on the room layout and client position. Standing on the side where the nurse is most comfortable is essential, but it is not the primary action compared to ensuring proper bed height.

C. Raise the side rail on the working side of the bed:
Raising the side rail on the working side of the bed could obstruct the nurse's access to the client and is not generally recommended during procedures requiring close access to the client.

D. Use the non-dominant hand to insert the catheter:
The dominant hand, in this case, the left hand, should be used to insert the catheter for better control and precision. The non-dominant hand is typically used to hold the genitalia and provide stability.
