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: 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.

The correct answer is choice C. Apply gentle pressure with a finger to the tragus of the ear.

Choice A rationale:

Chilling the medication prior to administration is not recommended. Cold ear drops can cause dizziness or discomfort when instilled into the ear. It is generally advised to warm the drops to body temperature by holding the bottle in your hands for a few minutes before administration.

Choice B rationale:

Holding the dropper against the ear canal while instilling the medication is incorrect. The dropper should be held above the ear canal to avoid contamination and injury. Touching the dropper to the ear canal can introduce bacteria and cause infection.

Choice C rationale:

Applying gentle pressure with a finger to the tragus of the ear helps to facilitate the flow of the medication into the ear canal. This action helps to ensure that the medication reaches the affected area effectively.

Choice D rationale:

Straightening the external auditory canal by pulling it down and back is incorrect for adults. For adults, the correct method is to pull the ear up and back to straighten the ear canal. Pulling it down and back is the method used for children.
