A nurse working in an urgent care clinic is collecting data from a client who takes montelukast.
Which of the following is an expected therapeutic effect of this medication?
Improved peripheral vasodilation.
Increased WBC Count.
Neutralized gastric acid.
Reduced bronchial inflammation.
The Correct Answer is D
Choice A rationale:
Montelukast does not improve peripheral vasodilation. It is a leukotriene receptor antagonist used to reduce inflammation in the airways.
Choice B rationale:
Montelukast does not increase the WBC count. It works by reducing inflammation in the airways, not by affecting the immune system.
Choice C rationale:
Montelukast does not neutralize gastric acid. It is not an antacid or proton pump inhibitor, it is used to reduce inflammation in the airways.
Choice D rationale:
Montelukast reduces bronchial inflammation. It helps to prevent asthma attacks and exercise-induced bronchoconstriction by reducing inflammation in the airways.

Correct Answer is A
Explanation
Choice A rationale:
Levalbuterol is a bronchodilator that relaxes muscles in the airways and increases air flow to the lungs. Therefore, a decrease in wheezing is a therapeutic effect of the medication, making this the correct choice.
Choice B rationale:
While levalbuterol can cause an increase in respiratory rate as a side effect, it is not considered a therapeutic effect of the medication. The primary goal of levalbuterol is to improve breathing by relaxing the muscles of the airways, not to increase respiratory rate.
Choice C rationale:
Levalbuterol does not directly affect nausea. It is primarily used to treat conditions related to breathing such as asthma and chronic obstructive pulmonary disease.
Choice D rationale:
An increased heart rate is a potential side effect of levalbuterol, not a therapeutic effect.
Correct Answer is A
Explanation
Choice A rationale:
A respiratory rate of 10/min is lower than the normal range (12-20 breaths per minute for adults), indicating respiratory depression, which is a serious side effect of morphine and should be reported immediately.
Choice B rationale:
Facial flushing is a common side effect of morphine due to histamine release but it’s not life-threatening.
Choice C rationale:
Constipation is a common side effect of morphine and can be managed with laxatives and diet.
Choice D rationale:
Blood pressure 88/56 mm Hg is lower than the normal range (90/60mmHg to 120/80mmHg), indicating hypotension, which can be a side effect of morphine but it’s not as immediately life-threatening as respiratory depression.
