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?

A. Asking the provider to repeat another radiograph of the chest.

This option is not the most appropriate action in this scenario. While a chest radiograph may be useful in certain situations to assess for complications such as pneumothorax or pneumonia, it is not typically the first intervention for an asthma exacerbation with increased wheezing and decreased oxygen saturation. In this acute situation, the priority is to provide immediate treatment to alleviate the client's symptoms and improve oxygenation.

B. Increasing oxygen to maintain an oxygen saturation of 95% or greater in the client.

While maintaining adequate oxygenation is important, especially in a client with asthma exacerbation, it is not the first-line intervention in this scenario. Oxygen supplementation may be necessary, but the priority is to address the underlying bronchospasm causing the decreased oxygen saturation. Therefore, this option may be considered after initiating appropriate bronchodilator therapy.

C. Requesting the pharmacy to dispense 10 mL of dextromethorphan PO.

This option is not appropriate for managing an asthma exacerbation. Dextromethorphan is a cough suppressant and does not address the underlying bronchospasm characteristic of asthma exacerbations. In fact, suppressing cough may hinder the clearance of mucus and exacerbate respiratory distress. Therefore, this intervention is not indicated and may delay appropriate treatment.

D. Instructing respiratory therapy to administer a PRN albuterol aerosol.

This is the correct action in this scenario. Albuterol is a short-acting bronchodilator commonly used to relieve bronchospasm and improve airflow in clients experiencing asthma exacerbations. Administering albuterol via aerosolized inhalation helps to quickly deliver the medication directly to the airways, providing rapid relief of symptoms such as wheezing and improving oxygenation. Therefore, instructing respiratory therapy to administer a PRN albuterol aerosol is the most appropriate intervention to address the client's acute symptoms.

A. Lower oxygen saturations of 93% to 94%

In an older adult client with a pneumothorax, the nurse could expect to observe lower oxygen saturations of 93% to 94%. A pneumothorax involves the accumulation of air in the pleural space, which can compress the lung and impair gas exchange, leading to hypoxemia (low blood oxygen levels). Decreased oxygen saturations would be a common finding in this condition.

B. Higher oxygen saturations of 98% to 99%

Higher oxygen saturations would be less likely in a client with a pneumothorax due to impaired gas exchange resulting from lung compression. Oxygen saturations are more likely to be lower in this condition, as indicated in option A.

C. Lower energy expenditure

While a pneumothorax may cause discomfort and dyspnea, which could potentially decrease energy expenditure due to reduced activity levels, it is not a direct physiological effect of the condition. Energy expenditure would depend on various factors, including the severity of symptoms and the individual's overall health status.

D. Increased lung capacity

A pneumothorax typically results in a decrease in lung capacity rather than an increase. The accumulation of air in the pleural space causes partial or complete collapse of the affected lung, reducing its ability to expand and decreasing overall lung capacity. Therefore, increased lung capacity would not be expected in a client with a pneumothorax.
