A nurse is caring for a client who is scheduled to undergo thoracentesis. In which of the following positions should the nurse place the client for the procedure?

A. Muscle twitching

Muscle twitching is not a typical manifestation of oxygen toxicity. Instead, muscle twitching may be indicative of other conditions such as electrolyte imbalances (e.g., hypocalcemia or hypomagnesemia), neuromuscular disorders, or overstimulation of the nervous system.

B. Metallic taste in mouth

A metallic taste in the mouth is not commonly associated with oxygen toxicity. Instead, a metallic taste in the mouth may occur as a side effect of certain medications, dental issues, or as a symptom of other medical conditions such as acid reflux or oral infections.

C. Facial flushing

Facial flushing is a characteristic finding in oxygen toxicity. When exposed to high levels of oxygen over an extended period, individuals may experience facial flushing due to the vasodilatory effects of oxygen on blood vessels. This dilation of blood vessels leads to increased blood flow to the face, resulting in flushing or reddening of the skin.

D. Periorbital edema

Periorbital edema, or swelling around the eyes, is not a typical manifestation of oxygen toxicity. Instead, periorbital edema may occur as a result of various other conditions such as allergies, sinusitis, or fluid retention. It is not directly related to exposure to high levels of oxygen.

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.
