A nurse in an assisted-living facility is reinforcing teaching with staff members about preparing for an external chemical disaster. Which of the following instructions should the nurse include?

Splinting the incision with a pillow when changing positions can provide support and help minimize discomfort and pain in clients who have undergone a cesarean birth. It can help reduce strain on the incision site and provide a sense of stability and comfort.

"You can apply counterpressure to your back with each position change" may be helpful for managing back pain, but it does not specifically address the client's request for nonpharmacological interventions to manage pain when changing positions after a cesarean birth.

"You should change positions as little as possible" is not an appropriate response as it does not address the client's need to manage pain when changing positions. Encouraging movement and position changes, along with appropriate support, can aid in recovery and prevent complications such as blood clots and respiratory issues.

"You should use patterned-paced breathing when changing positions" is not specifically related to managing pain when changing positions after a cesarean birth. While breathing techniques can be useful for pain management during labor and certain procedures, it may not be the most effective strategy for managing pain when changing positions post-cesarean.

Monitoring the infant's lymphocyte count is important in evaluating the immune function of the infant. HIV primarily affects the immune system, including lymphocytes. Monitoring the lymphocyte count helps assess the progression of the disease and the effectiveness of treatment.

Exchange transfusions are not typically used in the management of HIV. They are primarily performed in conditions like severe neonatal jaundice or blood disorders, but not for the treatment of HIV.

Granulocyte colony-stimulating factor (G-CSF) is a medication used to stimulate the production of white blood cells called granulocytes. While G-CSF can be used in certain situations, such as to counteract the side effects of certain chemotherapy drugs, it is not a standard treatment for HIV in infants.

Droplet precautions are typically implemented for infectious diseases that spread through respiratory droplets, such as influenza or respiratory syncytial virus (RSV). HIV does not spread through respiratory droplets, so initiating droplet precautions would not be necessary in the care of an infant with HIV.
