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 A
Explanation
A. Albuterol is a bronchodilator that provides quick relief by relaxing the muscles around the airways, making it essential to use before a corticosteroid like beclomethasone, which reduces inflammation. Using albuterol first allows for better delivery of the beclomethasone to the airways.
B. I will use both medications immediately after exercising. Albuterol may be used as a rescue inhaler before exercise to prevent exercise-induced bronchospasm, but beclomethasone is a maintenance medication and should not be used immediately after exercising unless prescribed.
C. "If my breathing begins to feel tight, I will use the beclomethasone inhaler immediately.” Beclomethasone is a long-term control medication, not a rescue inhaler. If breathing feels tight or there is an asthma attack, the client should use the albuterol inhaler for immediate relief.
D. I will administer the medications 10 minutes apart.While there is no strict rule about the timing between inhaler uses, the albuterol should be used first to open the airways, and while waiting a few minutes is acceptable, the emphasis should be on using albuterol before beclomethasone rather than a specific time frame.
Correct Answer is C
Explanation
This response demonstrates that the patient understands the dosing frequency (twice a day) and the importance of taking it with a full glass of water, which aligns with the instructions provided by the nurse.
The other choices are incorrect because:
A. "Taking this medication can cause me to develop a non-productive cough.": This response is about a potential side effect of the medication, rather than showing an understanding of the dosing instructions.
B. "I will take my medication Daily with a full glass of water.": This response indicates a misunderstanding of the dosing frequency, as the prescription specifically states "BID" (twice a day) rather than "daily."
D. "The medication will have to be given by my Home Health Nurse twice a day.": This response suggests a reliance on the home health nurse to administer the medication, which contradicts the instructions for the patient to take it themselves. It shows a misunderstanding of the patient's responsibility in self-administering the medication.
