The nurse is assessing the medication record of a newly admitted client. Which of the following medications directly interacts with oxymetazoline (Afrin)?
CNS Depressants
Short acting Beta Agonist
Monoamine oxidase inhibits
Mast Cell inhibitors
The Correct Answer is C
A. CNS Depressants: While there may be general concerns about using multiple medications that affect the central nervous system, CNS depressants do not have a direct interaction with oxymetazoline. Oxymetazoline is primarily a nasal decongestant and its interactions are more specific to other classes of medications.
B. Short Acting Beta Agonist: Short-acting beta agonists (SABAs) are bronchodilators used in asthma management. There is no direct interaction with oxymetazoline; they are used for different purposes and act on different receptors.
C. Monoamine oxidase inhibitors (MAOIs): This option is correct. MAOIs can potentially interact with oxymetazoline, leading to increased blood pressure and other cardiovascular effects. The combination can cause vasoconstriction due to the stimulant effects of both oxymetazoline and the increased levels of norepinephrine resulting from MAOI inhibition.
D. Mast Cell Inhibitors: Mast cell stabilizers do not interact directly with oxymetazoline. These medications are used primarily to manage allergic responses and asthma symptoms and do not have a significant effect on the actions of oxymetazoline.

Correct Answer is A
Explanation
A. Tachycardia: Theophylline can stimulate the heart, leading to an increase in heart rate. Tachycardia is a common adverse effect associated with theophylline use, and it is essential for the client to be aware of this potential side effect, especially if they have underlying heart conditions.
B. Constipation: While gastrointestinal side effects can occur with theophylline, constipation is not a primary or common adverse effect. Theophylline may actually lead to gastrointestinal upset or increased gastric acid production rather than causing constipation.
C. Drowsiness: Theophylline typically does not cause drowsiness. In fact, it is more likely to
cause restlessness or insomnia, as it is a stimulant. Thus, advising the client about drowsiness is not relevant in this case.
D. Oliguria: Oliguria (reduced urine output) is not a common adverse effect of theophylline. Theophylline can affect kidney function indirectly but does not typically present as oliguria. Monitoring for any renal changes is essential, but oliguria is not a primary concern.
Correct Answer is A
Explanation
A. This medication is for long-term treatment for asthma: This statement indicates an accurate understanding of montelukast. It is a leukotriene receptor antagonist used for long-term control and management of asthma symptoms and to prevent exercise-induced bronchoconstriction.
B. This medication has a tendency to produce anaphylaxis: This statement is incorrect. While allergic reactions can occur with montelukast, it is not commonly associated with anaphylaxis. Clients should be aware of potential side effects, but anaphylaxis is not a common risk.
C. I can repeat this medication twice prior to seeking medical attention: This statement is misleading. Montelukast is taken once daily for asthma management, and it is not meant to be repeated or used as a rescue medication in acute situations. Clients should seek medical attention for worsening symptoms instead of relying on repeating doses.
D. Bloodwork is required regularly to monitor the therapeutic levels of this medication: This statement is incorrect. Montelukast does not require routine blood monitoring for therapeutic levels, unlike some other medications used for asthma management. It is generally well-tolerated without the need for regular blood tests.
