(Round the answer to the nearest whole number. Use a leading zero it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["2"]

Identify the desired dose:

The doctor has ordered 25 mg of risperidone.

Identify the available medication concentration:

The available risperidone injection is 25 mg in 2 mL. This can be written as 25 mg/2 mL.

Set up the calculation:

We need to find out how many mL are needed to administer 25 mg of the medication. We can use the following formula:

(Desired dose) / (Concentration) = Volume to administer

Plug in the values and calculate:

(25 mg) / (25 mg/2 mL) = 2 mL

Correct Answer is ["1"]

Explanation

Convert milligrams (mg) to micrograms (mcg):

The desired dose is 0.5 mg.

We know that 1 mg = 1000 mcg.

Therefore, 0.5 mg = 0.5 x 1000 mcg = 500 mcg.

Identify the available tablet strength:

Each tablet contains 500 mcg of haloperidol.

Set up the calculation:

We need to find out how many tablets are needed to administer 500 mcg of the medication. We can use the following formula:

(Desired dose) / (Tablet strength) = Number of tablets

Plug in the values and calculate:

(500 mcg) / (500 mcg/tablet) = 1 tablet

A. Route B. Dose C. Time D. Medication

Correct Answer is C

Explanation

A) Route: The route of administration for escitalopram is typically oral, which is the most common and appropriate method for this medication. The prescription does not specify a different or unclear route, so there is no need for clarification in this case regarding the route of administration.

B) Dose: The prescribed dose of escitalopram is 10 mg daily, which falls within the standard therapeutic range for depression treatment. The dose does not appear to be problematic, as it aligns with usual practice for managing depression with escitalopram. Therefore, the dose does not require clarification.

C) Time: The prescription specifies escitalopram 10 mg daily but does not indicate a specific time of day for administration. Clarification of the time is important because certain medications may have different absorption rates or be better tolerated at specific times (e.g., morning or evening). The nurse should ask the provider to clarify if the medication should be taken at a specific time to maximize its effectiveness and minimize potential side effects, such as insomnia or sedation.

D) Medication: Escitalopram is correctly identified in the prescription and is an appropriate medication for the treatment of depression. There is no need to clarify this component, as it is already clearly specified in the prescription.
