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 C
Explanation
Status asthmaticus is a severe and potentially life-threatening asthma exacerbation that does not respond well to usual treatment measures. The primary goal in managing status asthmaticus is to relieve the bronchospasm and improve airflow. Short-acting 62-agonists, such as albuterol, are bronchodilators that work quickly to relax the smooth muscles of the airways, providing immediate relief of bronchospasm.
While determining the cause of the acute exacerbation and obtaining a peak flow reading are important aspects of asthma management, in the case of status asthmaticus, the immediate priority is to administer a bronchodilator to alleviate the severe symptoms and improve the child's breathing. Once the acute symptoms are addressed, further assessment and interventions can be carried out to identify the cause and monitor the child's condition.
Correct Answer is A
Explanation
Robitussin A-C contains codeine, which is an opioid antitussive that can have sedating effects. One of the major disadvantages of using this medication is the potential for drowsiness as a side effect. This can impair the client's ability to perform tasks that require alertness and can interfere with daily activities.
The other options listed are not the major disadvantage of antitussive therapy with Robitussin A-C:
The medication is irritating to the bronchial tree: Robitussin A-C is primarily used as an antitussive (cough suppressant) rather than for its effects on the bronchial tree. While it may have some mild irritant properties due to certain ingredients, it is not considered a major disadvantage of this medication.
The client may use the medication for 14 days: The duration of use for Robitussin A-C is typically determined by the healthcare provider based on the client's condition. While prolonged use of antitussives is generally not recommended without medical supervision, the duration of use is not considered the major disadvantage of this medication.
The medication is very expensive: The cost of medication can vary, and while cost may be a consideration for some individuals, it is not considered the major disadvantage of Robitussin
A-C specifically. The major disadvantage relates more to the potential for drowsiness caused by the medication.
