Answer and Explanation

The Correct Answer is ["3"]

tep-by-Step Solution

Understanding the Problem

The client needs risperidone 1.5 mg every 12 hours.

We have risperidone solution 1 mg/mL.

We need to find the total daily dose in mL.

Step 1: Calculate the total daily dose in mg

The client receives 1.5 mg every 12 hours.

There are 2 doses in a day (every 12 hours).

So, the total daily dose in mg is 1.5 mg/dose X 2 doses = 3 mg.

Step 2: Convert mg to mL

We know that 1 mg of risperidone is in 1 mL of solution.

We have a total daily dose of 3 mg.

So, to find the volume in mL, we can set up a proportion:

1 mg / 1 mL = 3 mg / x mL

Step 3: Solve for x

Cross-multiply: 1 mg X x mL = 1 mL X 3 mg

Simplify: x mL = 3 mL

Therefore, the nurse should administer a total daily dose of 3 mL.

Correct Answer is B

Explanation

A. Dose:
The dose of 2 mg is clearly specified in the prescription and does not need further clarification. It is the correct amount to administer based on the provided information.

B. Route:
The route of administration for haloperidol should be specified if it is not included in the prescription. Haloperidol can be administered orally, intramuscularly, or intravenously, and knowing the correct route is crucial to ensure proper and effective administration of the medication.

C. Frequency:
The frequency is indicated as "every 4 hr PRN" (as needed), which specifies how often the medication can be given. There is no need for further clarification regarding the frequency.

D. Medication:
The medication, haloperidol, is already identified in the prescription. There is no need to ask for clarification regarding the medication itself, as it is clearly stated.

Correct Answer is A

Explanation

A. Sertraline 125 mg daily:
Sertraline, a selective serotonin reuptake inhibitor (SSRI), is typically started at doses such as 50 mg or 100 mg daily for depression or anxiety, with adjustments based on response and tolerability. A dose of 125 mg daily is unusual and not a standard dose, so clarification is needed to ensure it is appropriate for the client and within the recommended dosing range.

B. Pantoprazole 40 mg PO BID:
Pantoprazole, a proton pump inhibitor, is commonly prescribed at 40 mg twice daily (BID) for conditions such as severe gastroesophageal reflux disease (GERD). This dosing is within the usual range for treating more severe acid-related conditions.

C. Propranolol extended release 80 mg PO daily:
Propranolol extended release 80 mg daily is a standard dose for managing conditions such as hypertension or anxiety. This dosage is appropriate and does not require clarification.

D. Clonidine transdermal 0.1 mg/24 hr apply every 7 days:
Clonidine transdermal patches are typically applied every 7 days, with doses of 0.1 mg/24 hr being a standard starting dose. This prescription aligns with common dosing guidelines and does not need clarification.
