A nurse is providing care to a client who has a history of asthma. The client presents with influenza symptoms that started the previous day. The provider orders an influenza test and prescribes an oral antiviral with instructions to begin the treatment as soon as possible. The client asks the nurse whether they can take the antiviral before the lab results are back. Which of the following responses by the nurse is appropriate?

A. Dry oral mucous membranes can occur with the use of inhalers but are not a serious adverse effect of beclomethasone. It can be managed with proper hydration and is not typically a cause for concern.
B. Tremors are more commonly associated with bronchodilators, such as beta-agonists, rather than corticosteroids like beclomethasone. They are not a typical side effect of beclomethasone MDI.
C. A white coating in the mouth may indicate oral thrush, a fungal infection caused by Candida species, which is a known adverse effect of inhaled corticosteroids like beclomethasone. The client should be instructed to rinse their mouth after each use to prevent this complication and report any signs of oral thrush to the provider.
D. Nausea is not a common adverse effect of inhaled corticosteroids. It is more often associated with systemic medications rather than inhaled therapies.

A. Impaired carbon dioxide elimination due to shunting: Shunting in ARDS affects oxygenation rather than carbon dioxide elimination. ARDS primarily results in impaired gas exchange due to inflammation and fluid accumulation in the alveoli, affecting oxygen rather than CO2.

B. Decreased pulmonary arterial pressure due to ventilation-perfusion (V/Q) mismatch: ARDS typically leads to increased pulmonary arterial pressure due to inflammation and decreased lung compliance. The V/Q mismatch contributes to impaired gas exchange, often resulting in elevated pulmonary arterial pressure rather than decreased.

C. Hypoxemia due to dead space: In ARDS, hypoxemia is primarily due to impaired gas exchange from damaged alveoli, not due to dead space. Dead space refers to areas where ventilation occurs without adequate blood flow, which is not the main issue in ARDS.

D. Decreased pulmonary compliance due to stiffness: ARDS is characterized by decreased pulmonary compliance due to the stiffness of the lung tissue caused by inflammation and edema. This decreased compliance makes lung expansion more difficult, which is a central feature of ARDS.
