A nurse is assessing a client who has asthma and signs of central cyanosis. Which of the following is a reliable indicator of cyanosis?

A. "I'll rinse my mouth after taking this medication."

Montelukast is taken orally and is not associated with the risk of oral thrush or other mouth-related side effects that would require rinsing the mouth after administration. This action is more commonly associated with inhaled corticosteroids, not leukotriene receptor antagonists.

B. "I'll use this medication when I get an asthma attack."

Montelukast is not a rescue medication for asthma attacks. It is a long-term controller medication used to manage and prevent asthma symptoms, not to treat acute attacks. Short-acting bronchodilators such as albuterol are used for quick relief during asthma attacks.

C. "I'll take this medication once a day in the evening."

Montelukast is a leukotriene receptor antagonist commonly used to manage asthma. It is typically taken orally once daily, usually in the evening, to provide 24-hour control of asthma symptoms and improve lung function. Therefore, the statement indicating an understanding of the teaching is option C.

D. "I'll decrease my sodium intake while I'm taking this medication."

Montelukast is not known to affect sodium levels in the body or require any specific dietary modifications, such as decreasing sodium intake. Therefore, this statement is unrelated to the use of montelukast for asthma management

A. Facial flushing

Facial flushing is not typically associated with atelectasis. Instead, it may occur in conditions such as oxygen toxicity or fever.

B. Increasing dyspnea

Atelectasis is a condition characterized by the collapse or partial collapse of a portion of the lung. Common findings in a client with atelectasis include increasing dyspnea (shortness of breath) due to impaired gas exchange and reduced lung function. As the affected lung tissue collapses, ventilation and oxygenation are compromised, leading to difficulty breathing.

C. Decreasing respiratory rate

A decreasing respiratory rate is not typically observed in a client with atelectasis. Instead, respiratory rate may increase as the body attempts to compensate for the impaired gas exchange and oxygenation resulting from lung collapse.

D. Dry cough

While coughing is a common symptom of atelectasis, it is typically associated with a productive cough rather than a dry cough. A dry cough is more commonly associated with conditions such as viral respiratory infections or allergic reactions. In atelectasis, the cough may be productive as the body attempts to clear mucus or other secretions from the affected airways.
