A nurse is preparing to administer hydroxyzine 60 mg PO every 8 hr to a client who has generalized anxiety disorder. Available is hydroxyzine 10 mg/5 mL solution. How many mL should the nurse administer for the total daily dose? (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 ["90ml"]
To find out how many mL the nurse should administer for the total daily dose, we need to calculate the total daily dose and then convert it to mL using the available concentration.
The client is prescribed hydroxyzine 60 mg PO every 8 hours. To find the total daily dose, we can first calculate the dose per day and then convert it to mL.
Dose per day = Dose per dose interval x Number of doses per day
Dose per day = 60 mg x 3 (every 8 hours)
Dose per day = 180 mg per day
Now, we need to convert this dose to mL using the available concentration:
Concentration: 10 mg/5 mL
To find out how many mL for 180 mg, we can set up a proportion:
(10 mg / 5 mL) = (180 mg / x mL)
Cross-multiply:
10 mg * x mL = 5 mL * 180 mg
Now, solve for x (the number of mL):
x mL = (5 mL * 180 mg) / 10 mg
x mL = 900 mL / 10 mg
x mL = 90 mL
So, the nurse should administer 90 mL for the total daily dose.

Correct Answer is D
Explanation
A. Magnesium hydroxide:
Magnesium hydroxide is an antacid commonly used to relieve indigestion and heartburn. It does not have any known significant interactions with tranylcypromine. MAOIs typically do not interfere with antacids.
B. Ibuprofen:
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) used to reduce pain and inflammation. It does not have specific interactions with tranylcypromine. However, individuals taking MAOIs should be cautious about using NSAIDs due to the potential risk of bleeding, especially gastrointestinal bleeding. While it's not a direct interaction, it's generally advisable for individuals taking MAOIs to consult their healthcare provider before using NSAIDs.
C. Ranitidine:
Ranitidine is an H2 blocker used to reduce stomach acid production. It does not have any known significant interactions with tranylcypromine. H2 blockers like ranitidine are often used to manage gastrointestinal issues and are generally considered safe when taken with MAOIs.
D. Pseudoephedrine:
Pseudoephedrine is a decongestant commonly found in cold and allergy medications. It can cause a dangerous increase in blood pressure when combined with MAOIs, potentially leading to a hypertensive crisis. Due to this serious interaction, individuals taking MAOIs are strongly advised to avoid medications containing pseudoephedrine.
Correct Answer is A
Explanation
A. "This medication is given to help with extrapyramidal side effects."
Benztropine is an anticholinergic medication used to treat the extrapyramidal side effects (EPS) caused by certain psychiatric drugs, particularly antipsychotics. EPS can include symptoms such as muscle stiffness, restlessness, tremors, and other movement disorders. Benztropine helps to alleviate these symptoms, making it an essential medication for individuals experiencing these side effects from antipsychotic medications.
B. "Benztropine helps alleviate your hallucinations."
This statement is incorrect. Benztropine is not primarily used to treat hallucinations; it is used for movement-related side effects as mentioned above.
C. "This medication is given to help with your depression."
This statement is incorrect. Benztropine is not indicated for the treatment of depression.
D. "Benztropine is used to counteract your tachycardia."
This statement is incorrect. Benztropine is not used to treat tachycardia (fast heart rate). It is specifically used for extrapyramidal side effects related to antipsychotic medications.
