A patient has a diagnosis of Impaired Gas Exchange. Which assessment finding shows that the interventions have been effective?

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. Oral mucosa:

The oral mucosa, including the inside of the mouth, tongue, and lips, is a reliable indicator of cyanosis. Cyanosis appears as a bluish discoloration of these tissues due to decreased oxygen saturation in the arterial blood. Assessing the oral mucosa is an essential component of clinical examination, especially in patients with respiratory conditions like asthma, as it provides valuable information about oxygenation status.

B. Tip of the nose:

While the tip of the nose may exhibit cyanosis in some cases, it is not considered as reliable of an indicator as the oral mucosa. The nasal tip is more susceptible to external factors such as cold temperatures or poor circulation, which can cause temporary discoloration. Therefore, it may not always accurately reflect the oxygenation status of the patient compared to the oral mucosa.

C. Ear lobes:

Cyanosis may be observed in the ear lobes in cases of severe hypoxemia, but it is not as reliable of an indicator as the oral mucosa. The ear lobes are less commonly assessed for cyanosis compared to other areas such as the lips, nail beds, or oral mucosa. While cyanosis may be present in the ear lobes, it is not typically the primary site assessed for oxygenation status.

D. Eyelids:

Cyanosis is not typically observed in the eyelids and is not considered a reliable indicator of hypoxemia. The eyelids are not commonly assessed for cyanosis during clinical examinations. While the conjunctiva (the lining inside the eyelids) may appear pale in cases of severe anemia, it is not a specific sign of hypoxemia. Assessment of the oral mucosa, lips, and nail beds is preferred for evaluating oxygenation status in patients with respiratory conditions like asthma.
