Acetylcysteine (Mucomyst) is a mucolytic that can also be used in the treatment of overdosage of which drug?
Ibuprofen
Diphenhydramine
Acetaminophen
Amoxicillin
The Correct Answer is C
Acetaminophen overdose can cause liver damage, and acetylcysteine is used as an antidote to prevent or minimize the liver injury caused by acetaminophen toxicity. Acetylcysteine works by replenishing glutathione, a substance that helps neutralize the toxic byproducts of acetaminophen metabolism in the liver.
It is important to note that acetylcysteine is specifically indicated for acetaminophen overdose and may not be effective or appropriate for overdosage of other drugs, such as ibuprofen, diphenhydramine, or amoxicillin.

Correct Answer is D
Explanation
Diphenhydramine is an antihistamine medication that can cause sedation as a side effect. Taking most of the daily dose at bedtime can help minimize daytime sedation. By taking the medication closer to bedtime, the sedative effects are more likely to occur during sleep, reducing the impact of sedation during waking hours.
The other options mentioned are not effective strategies to minimize daytime sedation caused by diphenhydramine:
A. "Distribute the doses evenly throughout the day": This approach may lead to a consistent level of sedation throughout the day and may not effectively minimize daytime sedation.
B. "Gradually decrease the dose once tolerance to the effect is reached": Gradually decreasing the dose of diphenhydramine is not a recommended strategy for minimizing daytime sedation. It is important to follow the prescribed dose and consult with a healthcare provider before making any changes to the medication regimen.
C. "Take the medication with meals": Taking diphenhydramine with meals may help reduce the risk of stomach upset but does not directly address the issue of daytime sedation.
Correct Answer is D
Explanation
Leukotriene receptor antagonists (LTRAs) like Montelukast are commonly used in the treatment of asthma. They work by blocking the action of leukotrienes, which are inflammatory substances that can cause narrowing and inflammation of the airways in individuals with asthma. By preventing this inflammation, LTRAs help to reduce asthma symptoms and prevent asthma attacks.
The other options mentioned in the statements are not accurate or appropriate for teaching about Montelukast. Taking the medication only when experiencing symptoms is not the recommended approach, as LTRAs are typically taken regularly as part of ongoing asthma management. The statement about the therapeutic effect taking several weeks to notice is not accurate, as Montelukast can start to provide symptom relief within a shorter timeframe.
Additionally, the statement about increasing fiber and fluid intake to prevent constipation is unrelated to the use of Montelukast and may not apply to this medication specifically.
