A nurse is reinforcing teaching with the parents of a child who is starting to use a spacer with a metered-dose inhaler (MDI) to treat asthma. Which of the following information should the nurse include in the teaching?

Correct Answer: C

Rationale: The spacer helps to deliver more medication to the lungs by holding the medication in the chamber, allowing the patient to inhale it more slowly and deeply. This results in better deposition of the medication in the lower airways and reduces the amount of medication that is deposited in the mouth and throat.

Correct Answer: A

Rationale: In a client with anemia, the primary indication for oxygen therapy is to increase the oxygen-carrying capacity of the blood and improve tissue oxygenation.

Correct Answer: D

Rationale: A CPAP mask is the most appropriate oxygen delivery system for a client with sleep apnea who requires positive pressure ventilation. It delivers a continuous flow of pressurized air to keep the airways open during sleep.

Correct Answer: C

Rationale: NPPV devices, such as continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BIPAP), can cause dry mouth. Providing frequent oral care, such as mouth rinses and moisturizing agents, helps alleviate discomfort and prevent oral complications.

Correct Answer: B

Rationale: Securing the oxygen tubing under furniture legs can create a potential safety hazard by causing the tubing to become twisted or pulled, disrupting the oxygen flow. It is important to educate the client about keeping the tubing free from obstructions and ensuring it is positioned safely.
