How many tablets should the nurse administer in each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing, zero.)

Answer and Explanation

The Correct Answer is ["2"]

Calculate the dose per administration:

The total daily dose is 300 mg, divided equally every 12 hours.

There are 24 hours in a day, so there are 24 hours / 12 hours = 2 doses per day.

Each dose is 300 mg / 2 doses = 150 mg.

Calculate the number of tablets per dose:

Each tablet contains 75 mg of amitriptyline.

The required dose is 150 mg.

150 mg / 75 mg per tablet = 2 tablets per dose

Correct Answer is ["1.6"]

Explanation

Identify the desired dose:

The doctor has ordered 40 mg of chlorpromazine hydrochloride.

Identify the concentration of the available medication:

The available chlorpromazine hydrochloride injection is 25 mg/mL.

Set up the calculation:

We need to find out how many mL are needed to administer 40 mg of the medication. We can use the following formula:

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

Plug in the values and calculate:

(40 mg) / (25 mg/mL) = 1.6 mL

A. Propranolol extended release 80 mg PO daily B. Sertraline 125 mg daily C. Clonidine transdermal 0.1 mg/24 hr apply every 7 days D. Pantoprazole 40 mg PO BID

Correct Answer is B

Explanation

A) Propranolol extended release 80 mg PO daily: This prescription is appropriate. Propranolol is a beta-blocker used for various conditions, such as hypertension, anxiety, and arrhythmias. The prescribed dose of 80 mg daily is within the standard dosage range for extended-release propranolol and is commonly prescribed for these conditions.

B) Sertraline 125 mg daily: This prescription should be clarified. The typical dosage for sertraline (a selective serotonin reuptake inhibitor, or SSRI) is 50–100 mg daily for most adults, with 125 mg being above the usual starting dose. While higher doses (up to 200 mg daily) are sometimes used, 125 mg daily is not typical and should be clarified with the provider to ensure it is correct.

C) Clonidine transdermal 0.1 mg/24 hr apply every 7 days: This prescription is appropriate. Clonidine is used to treat hypertension, and the 0.1 mg/24 hr transdermal patch is commonly prescribed, applied every 7 days. This is a standard dosing regimen for the transdermal formulation.

D) Pantoprazole 40 mg PO BID: This prescription is appropriate. Pantoprazole, a proton pump inhibitor (PPI), is typically dosed at 40 mg twice daily (BID) for conditions like gastroesophageal reflux disease (GERD) or peptic ulcers. The prescribed dose and frequency are consistent with common clinical practice for more severe cases.
