A client has a new prescription for montelukast.
What information should the practical nurse (PN) include when reinforcing the client’s teaching?
Montelukast will increase the production of mucus in the lungs.
The medication will prophylactically limit the inflammatory response to allergens.
The medication will contract the smooth muscles located in the respiratory tract.
Montelukast will help repair damaged tissue in the base of the lungs.
The Correct Answer is B
Choice A rationale
Montelukast does not increase the production of mucus in the lungs. In fact, it helps to reduce inflammation and may be used to prevent asthma attacks.
Choice B rationale
Montelukast is a leukotriene modifier that helps to reduce inflammation and prevent asthma attacks and exercise-induced bronchoconstriction. It works by blocking the action of leukotriene D4 in the lungs resulting in decreased inflammation and relaxation of smooth muscle. This prophylactic limitation of the inflammatory response to allergens is a key function of montelukast.
Choice C rationale
Montelukast does not contract the smooth muscles located in the respiratory tract. Instead, it helps to relax the smooth muscles in the lungs, reducing inflammation and making it easier to breathe.
Choice D rationale
Montelukast does not directly repair damaged tissue in the base of the lungs. Its primary function is to prevent and manage symptoms of asthma and allergies by reducing inflammation in the airways.

Correct Answer is C
Explanation
Choice A rationale
Involuntary movements of the lips and tongue are typically associated with antipsychotic medications, not nonsteroidal anti-inflammatory drugs (NSAIDs) like ketorolac15. Therefore, observing the client for these symptoms would not be a relevant intervention for a client taking ketorolac15.
Choice B rationale
Administering the medication at least 30 minutes before meals is not a specific requirement for ketorolac15. Therefore, this would not be a necessary intervention for a client taking this medication15.
Choice C rationale
Ketorolac, like other NSAIDs, can increase the risk of bleeding15. This can manifest as areas of ecchymosis (bruising) or other signs of bleeding on the skin15. Therefore, assessing the skin daily for these signs would be an important intervention for a client taking ketorolac15.
Choice D rationale
Peak and trough serum levels are typically monitored for medications with a narrow therapeutic index, such as certain antibiotics15. Ketorolac does not typically require
monitoring of serum levels15. Therefore, ensuring peak and trough serum levels are collected would not be a necessary intervention for a client taking this medication15.
Correct Answer is C
Explanation
Choice A rationale
Diminished urinary urgency is an expected outcome of oxybutynin treatment, as the
medication works by relaxing the muscles of the bladder.
Choice B rationale
Reduced urinary frequency is another expected outcome of oxybutynin treatment.
Choice C rationale
Decreased urinary output is not a typical effect of oxybutynin. In fact, oxybutynin is used to
manage symptoms of an overactive bladder, which include frequent urination. Therefore, if the
PN observes decreased urinary output, it could indicate a problem such as urinary retention,
which should be reported to the charge nurse.
Choice D rationale
Less frequent urinary incontinence is an expected outcome of oxybutynin treatment.
