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
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.
Correct Answer is C
Explanation
The sympathetic nervous system postganglionic neurons primarily release norepinephrine as their neurotransmitter. These neurons are part of the autonomic nervous system and are responsible for coordinating the body's "fight or flight" response to stress or danger.
Norepinephrine acts as a neurotransmitter at the postganglionic synapses and binds to adrenergic receptors in the target tissues, mediating the physiological responses associated with sympathetic activation.
While acetylcholine is the primary neurotransmitter released by the preganglionic neurons of the sympathetic nervous system, it is not the neurotransmitter released by postganglionic neurons. Epinephrine (also known as adrenaline) is released into the bloodstream by the adrenal medulla and acts as a hormone, not a neurotransmitter. Arginine is an amino acid and is not directly involved in the neurotransmission of the sympathetic nervous system.
