The nurse knows that montelukast (Singulair) is given for what purpose?
Seasonal allergy only
Severe asthmatic attacks
Acute bronchospasm
Maintenance and prevention of asthma
The Correct Answer is D
A. Seasonal allergy only
Montelukast may be used for the treatment of allergic rhinitis associated with seasonal allergies, but its primary use is for asthma prevention.
B. Severe asthmatic attacks
Montelukast is not typically used for the treatment of severe asthmatic attacks. Short-acting bronchodilators and systemic corticosteroids are more commonly used in this scenario.
C. Acute bronchospasm
While montelukast has a role in the prevention of bronchospasm, it is not typically used for the acute treatment of bronchospasm. Short-acting bronchodilators are more appropriate for immediate relief of bronchospasm.
D. Maintenance and prevention of asthma
Montelukast (Singulair) is used for the maintenance and prevention of asthma. It is a leukotriene receptor antagonist that works by blocking the action of leukotrienes, which are inflammatory mediators involved in the pathophysiology of asthma. By inhibiting leukotrienes, montelukast helps to reduce airway inflammation and bronchoconstriction, thereby preventing asthma symptoms.

Correct Answer is B
Explanation
A. Relieves nasal congestion
Dornase alfa is not used to relieve nasal congestion. It is specifically designed to address the thick, sticky mucus that can accumulate in the airways of individuals with cystic fibrosis (CF).
B. Decreases thick secretions
This is the correct answer. Dornase alfa is known for its ability to decrease the viscosity of thick secretions in the airways of individuals with CF. By breaking down the DNA within the mucus, it helps to thin and improve the clearance of the mucus.
C. Decreases pain
Dornase alfa is not primarily used to decrease pain. Its main action is related to improving respiratory function by reducing the thickness of mucus, which can help ease breathing difficulties associated with CF.
D. Suppresses cough
Dornase alfa is not used to suppress cough. In fact, it may increase coughing initially as it facilitates the loosening and clearance of mucus from the airways.
Correct Answer is C
Explanation
A. “This medication is a leading cause of bronchospasm.”
Glucocorticoid inhalers are not a leading cause of bronchospasm. In fact, they are often prescribed to reduce inflammation and prevent bronchospasm in conditions like asthma and chronic obstructive pulmonary disease (COPD).
B. “This medication will cause you to become fatigued.”
Fatigue is not a common side effect of inhaled glucocorticoids. Systemic effects are more likely with oral or intravenous administration, whereas inhaled forms are designed to have localized effects.
C. “You must gargle and rinse your mouth immediately after each use of this medication.”
Inhaled glucocorticoids can sometimes lead to local side effects, such as oral candidiasis (thrush) or hoarseness. Gargling and rinsing the mouth after using the inhaler can help minimize these side effects by reducing the risk of fungal overgrowth in the mouth and throat.
D. “This medication may cause you to feel anxious.”
Anxiety is not a common side effect of inhaled glucocorticoids. Again, systemic effects are more associated with other routes of administration. The use of inhaled glucocorticoids is generally well-tolerated when used as directed.
