A nurse is reinforcing teaching with a client who is to start taking montelukast to treat asthma. Which of the following statements by the client indicates an understanding of the teaching?

A. The spacer increases the amount of medication delivered to the oropharynx.

Spacers are designed to minimize the amount of medication deposited in the oropharynx (back of the throat) and reduce the risk of side effects such as oral thrush or hoarseness. The main purpose of using a spacer is to optimize the delivery of medication to the lungs.

B. The spacer increases the amount of medication delivered to the lungs.

When reinforcing teaching with the parents of a child who is starting to use a spacer with a metered-dose inhaler (MDI) to treat asthma, the nurse should include the information that the spacer increases the amount of medication delivered to the lungs. Spacers help improve the delivery of medication from the MDI to the lungs by reducing the need for coordination between actuation of the MDI and inhalation. They also slow down the speed of the aerosolized medication particles, allowing more time for them to be inhaled into the lungs effectively.

C. Inhale rapidly when using the spacer with the MDI.

Inhaling rapidly may lead to improper inhalation technique and reduce the effectiveness of medication delivery to the lungs. Instead, the child should be instructed to inhale slowly and deeply to ensure that the medication reaches the lower airways.

D. Cover exhalation slots of the spacer with lips when inhaling.

Covering the exhalation slots of the spacer with lips during inhalation is not recommended. These slots are designed to allow the child to exhale freely and prevent buildup of pressure within the spacer. Encouraging the child to exhale into the spacer would hinder proper inhalation technique and could lead to decreased medication delivery to the lungs.

A. Place the client in left Sims' position.

Left Sims' position is a lateral position used primarily for rectal examinations or procedures. It involves lying on the left side with the lower arm positioned behind the body and the upper knee flexed. This position is not indicated for a client post-tracheostomy. It does not provide any specific benefit for tracheostomy care and may not be comfortable or appropriate for a client recovering from tracheostomy surgery.

B. Provide humidified air.

Providing humidified air is crucial for clients post-tracheostomy to maintain moisture in the airway and prevent drying of secretions. Tracheostomy bypasses the upper airway's natural humidification mechanism, which can lead to drying of the mucous membranes and increased risk of complications such as mucus plugging and infection. Humidified air helps keep the secretions moist, facilitates their removal, promotes airway clearance, and reduces the risk of complications.

C. Clean the tracheostomy stoma with povidone-iodine.

While povidone-iodine is an antiseptic solution commonly used for skin preparation before invasive procedures, it is not typically used to clean the tracheostomy stoma, especially in the immediate postoperative period. Cleaning the stoma should be performed using sterile technique and appropriate solutions as directed by the healthcare provider. Using povidone-iodine may not be suitable for cleaning the tracheostomy stoma and could potentially irritate the area or introduce contaminants.

D. Use clean technique when providing tracheostomy suctioning.

Tracheostomy suctioning should always be performed using sterile technique to minimize the risk of introducing pathogens into the lower airway and causing infection. Clean technique, which involves washing hands and using clean gloves, is not appropriate for tracheostomy care, particularly in the immediate postoperative period when the risk of infection is higher. Sterile technique involves the use of sterile gloves, sterile suction catheters, and maintaining a sterile field to ensure the safety and cleanliness of the procedure.
