A nurse is reinforcing teaching with the parents of a child who has ADHD and is taking methylphenidate. Which of the following statements by the parents indicates that the medication is effective?

Explanation:

A nasal cannula is a device used to deliver supplemental oxygen to a client. It consists of two prongs that are inserted into the client's nostrils and connected to an oxygen source. The nasal cannula is commonly used for low-flow oxygen delivery at a rate of 1 to 2 liters per minute (L/min).

The other options mentioned are not necessary supplies for the client upon discharge:

B- Petroleum jelly is not directly related to oxygen therapy and is not a required supply for the client. It is a common topical ointment used for various purposes such as moisturizing the skin or protecting the lips, but it is not specifically needed for oxygen administration.

C- An oxygen mask is an alternative device for oxygen delivery but is not typically used at a flow rate of 1 to 2 L/min. Oxygen masks are usually employed for higher flow rates or in specific clinical situations that require a different oxygen delivery method.

D- A reservoir bag is a component of some oxygen delivery systems, such as a non-rebreather mask or a bag-valve-mask device. However, at a flow rate of 1 to 2 L/min, a reservoir bag is not typically used. It is more commonly utilized in situations where higher oxygen concentrations or higher flow rates are required.

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.
