A nurse is preparing to administer haloperidol lactate 12 mg PO for a client who has schizophrenia and who cannot swallow tablets.

Available is haloperidol 2 mg/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.)

Answer and Explanation

The Correct Answer is ["6"]

Step 1 is to determine the amount of haloperidol lactate that needs to be administered, which is 12 mg.

Step 2 is to calculate the volume of the haloperidol oral solution needed to deliver this dose. This is done using the formula:

Dose (mg) ÷ Concentration (mg/mL)

Given that the available concentration is 2 mg/mL, we calculate:

12 mg ÷ 2 mg/mL = 6 mL

Therefore, the nurse should administer 6 mL of the haloperidol oral solution.

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.

Correct Answer is ["3"]

Explanation

Step 1: Identify Given Information

Prescribed dose: 7.5 mg
Available tablet strength: 2.5 mg per tablet

Step 2: Calculate the Number of Tablets

To determine how many tablets to administer, divide the prescribed dose by the strength of each tablet:

7.5 mg ÷ 2.5 mg/tablet = 3 tablets

The nurse should administer 3 tablets of olanzapine.
