A client's dose of benazapril is increased from 10 to 20 mg PO daily. The medication is available in 5 mg tablets. The nurse administered 10 mg one hour before the health-care provider revised the prescription. How many additional tablets should the nurse administer now? (Enter numeric value only.)

Answer and Explanation

The Correct Answer is ["2"]

To calculate the number of additional tablets needed, we'll first determine the total number of tablets required for the new dose of 20 mg.

Step 1: Calculate the total number of tablets needed for the new dose:

Total Tablets = Desired Dose (mg) / Tablet Strength (mg)

Total Tablets = 20 mg / 5 mg/tablet

Total Tablets = 4 tablets

Step 2: Determine the number of tablets already administered:

The nurse administered 10 mg, which is equivalent to 2 tablets (since each tablet is 5 mg).

Step 3: Calculate the number of additional tablets needed:

Additional Tablets = Total Tablets - Tablets Already Administered

Additional Tablets = 4 tablets - 2 tablets

Additional Tablets = 2 tablets

Therefore, the nurse should administer 2 additional tablets of benazapril to reach the new prescribed dose of 20 mg.

Correct Answer is C

Explanation

To calculate the infusion time, we'll use the following formula:

Infusion Time (hours) = Total Volume (mL) / Infusion Rate (mL/hour)

Plugging in the given values:

Infusion Time = 1000 mL / 75 mL/hour

Calculating the result:

Infusion Time ≈ 13.33 hours

Converting hours to minutes:

0.33 hours x 60 minutes/hour ≈ 20 minutes

Therefore, the infusion will be completed approximately 13 hours and 20 minutes after it started at 0300.

Adding 13 hours and 20 minutes to 0300:

0300 + 13 hours + 20 minutes = 1620

So, the correct answer is C. 1620.

Correct Answer is ["4.9"]

Explanation

Step 1: Calculate the concentration of dopamine in the IV solution:

400 mg / 250 mL = 1.6 mg/mL

Step 2: Calculate the infusion rate in mL/minute:

12 mL/hour x (1 hour / 60 minutes) = 0.2 mL/minute

Step 3: Calculate the dopamine infusion rate in mg/minute:

0.2 mL/minute x 1.6 mg/mL = 0.32 mg/minute

Step 4: Convert milligrams to micro-grams:

0.32 mg x (1000 mcg / 1 mg) = 320 mcg/minute

Step 5: Calculate the dopamine infusion rate in mcg/kg/minute:

320 mcg/minute / 65 kg ≈ 4.9 mcg/kg/minute

Therefore, the client is receiving approximately 4.9 mcg/kg/minute of dopamine.
