A nurse is preparing to administer amantadine 150 mg PO for a client who is experiencing parkinsonism due to an antipsychotic medication.
Available is amantadine 50 mg/5 mL oral solution.
How many mL should the nurse administer? (Round the answer to the nearest whole number.
Use a leading zero if it applies.
Do not use a trailing zero
The Correct Answer is ["15 mL."]
Step 1 is to determine the amount of amantadine needed. The prescription is for 150 mg and the available solution is 50 mg/5 mL. Step 2 is to set up a proportion to find the volume needed: (150 mg ÷ 50 mg) × 5 mL. This gives us 15 mL.
So, the correct answer is 15 mL.

Correct Answer is ["answer is 2 tablets."]
Explanation
Step 1 is: Identify the prescribed dose, which is 150 mg. Step 2 is: Identify the available dose, which is 75 mg per tablet. Step 3 is: Divide the prescribed dose by the available dose. So, 150 mg ÷ 75 mg/tablet. Step 4 is: The result is 2 tablets.
So, the correct answer is 2 tablets.
Correct Answer is C
Explanation
The correct answer is: C. Avocados.
Choice A reason: Milk, especially when fresh and not aged, is generally low in tyramine. The tyramine content in milk does not significantly increase unless the milk is fermented or nearing expiration. Therefore, 2 % milk is considered a safe option for individuals taking MAOIs.
Choice B reason: Fresh fruits like apples are typically low in tyramine. However, as fruits ripen or become overripe, their tyramine content can increase. Since the question specifies “sliced apples,” which are likely to be fresh, they would not have a high tyramine content and are considered safe for someone on MAOIs.
Choice C reason: Avocados, particularly if they are overripe, contain higher levels of tyramine compared to other foods listed. Overripe avocados can have a tyramine content that is high enough to be of concern for individuals taking MAOIs, making them the food choice with the highest tyramine content among the options provided.
Choice D reason: Celery is a low-tyramine food and is safe for consumption by individuals on MAOI therapy. There is no significant increase in tyramine content in celery, even as it ages, making it a suitable option for those with dietary restrictions related to MAOIs.
