A nurse enters a client's room to administer medication and finds the client lying in bed disoriented with labored and fast respirations. Which of the following actions should the nurse take first?

First, we need to find out how many milligrams (mg) are in 1 milliliter (mL) of the available diphenhydramine solution:

12.5 mg/5 mL

To find out how many milligrams are in 1 mL, we divide the total milligrams by the total milliliters:

12.5 mg ÷ 5 mL = 2.5 mg/mL

Now that we know the concentration of diphenhydramine is 2.5 mg/mL, we can calculate the dose needed for the order of 25 mg:

25 mg ÷ 2.5 mg/mL = 10 mL

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
