Flashcards

Montelukast Timing

Take montelukast once daily in the evening for asthma management.

Ipratropium and Dry Mouth

Ipratropium can cause dry mouth, so sucking on hard candy is a good way to relieve it. The nurse doesn't need to clarify this.

Guaifenesin and Hydration

Increase fluid intake promotes guaifenesin's therapeutic effect by thinning secretions.

Albuterol Caution

Albuterol should be used cautiously in patients with cardiovascular disease due to its potential to cause tachycardia and hypertension.
