A contraindication for the use of Acetaminophen (Tylenol) in a patient is:
Hypertension
Gallbladder Disease
Severe hepatic impairment
Tachyarrhythmias
The Correct Answer is C
Acetaminophen is generally considered safe and well-tolerated when used appropriately. However, it is primarily metabolized by the liver, and in cases of severe hepatic impairment or liver failure, the metabolism of acetaminophen can be significantly impaired. This can lead to the accumulation of toxic metabolites, which can cause further liver damage and potentially result in hepatotoxicity.
Hypertension, gallbladder disease, and tachyarrhythmias are not typically considered contraindications for the use of acetaminophen. However, it is important to consider any potential interactions or precautions when using acetaminophen in patients with these conditions, and consulting with a healthcare provider is recommended to ensure the safe and appropriate use of the medication.

Correct Answer is C
Explanation
When using an albuterol inhaler, it is important for the client to take a slow and deep inhalation while releasing the medication from the inhaler. After inhaling the medication, holding the breath for about 10 seconds allows the medication to reach deep into the airways and maximize its effectiveness.
The other actions mentioned are not correct:
A. Waiting 10 minutes between inhalations: Albuterol inhalers are typically used as a quick-relief medication for acute symptoms, and waiting 10 minutes between inhalations may not provide immediate relief when needed. The specific instructions on the frequency of inhalations should be provided by the healthcare provider.
B. Taking a quick inhalation while releasing the medication from the inhaler: It is important to take a slow and deep inhalation while releasing the medication to ensure that the medication reaches the lungs effectively. Taking a quick inhalation may result in less effective delivery of the medication.
D. Exhaling as the medication is released from the inhaler: It is important to exhale fully before using the inhaler to ensure that the medication is inhaled deeply into the lungs. Exhaling while releasing the medication can interfere with the proper inhalation technique.
Correct Answer is C
Explanation
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.
