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","D"]
Explanation
The nurse should make the following responses regarding how albuterol helps the client's breathing:
- The medication will open the airways.
- The medication will prevent wheezing.
Albuterol is a bronchodilator medication commonly used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). It works by relaxing the smooth muscles in the airways, leading to the dilation of the bronchial tubes and increased airflow. This mechanism helps open up the airways and prevent or relieve symptoms such as wheezing, shortness of breath, and chest tightness.
The other options are incorrect because:
The medication will decrease coughing episodes: While albuterol may indirectly reduce coughing episodes by opening up the airways and improving airflow, its primary effect is on bronchodilation rather than directly targeting coughing.
The medication will stimulate the flow of mucus: Albuterol is not known to stimulate mucus flow. Instead, it focuses on bronchodilation to improve airflow in the lungs.
The medication will reduce inflammation: Albuterol is primarily a bronchodilator and does not have a significant anti-inflammatory effect. Other medications, such as corticosteroids, are typically used to address inflammation in respiratory conditions.

Correct Answer is C
Explanation
Benzonatate is available in capsule form (such as Tessalon Pearls), and it should be swallowed whole. It is important not to chew, crush, or break the capsules as this can cause adverse effects, including local anesthesia in the oral cavity, which can lead to choking or difficulty swallowing. Swallowing the capsule whole ensures that the medication is released properly in the stomach for the desired effect.
The other options mentioned are incorrect:
A. Eating a high-fat meal prior to taking medication: There is no specific requirement to eat a high-fat meal before taking Benzonatate. However, taking it with food or a glass of water may help with ease of swallowing.
B. Taking medication often and whenever a cough is starting: Benzonatate should be taken as directed by the healthcare provider. It is not recommended to take it more frequently or as needed, as it can lead to an overdose or unwanted side effects.
D. Taking medication with orange juice: There is no specific requirement to take Benzonatate with orange juice. It can be taken with water or other non-alcoholic beverages as directed by the healthcare provider.
