A client with rheumatoid arthritis receives a prescription for etanercept 25 mg. The medication is available in a prefilled syringe labeled, 50 mg/2 ml. How many ml should the nurse administer? (Enter the numerical value only.)

Answer and Explanation

The Correct Answer is ["1.0"]

To calculate the volume of etanercept to be administered, we can use the following formula:

Volume (mL) = Desired Dose (mg) / Concentration (mg/mL)

Plugging in the given values:

Volume (mL) = 25 mg / 50 mg/mL

Volume (mL) = 0.5 mL

Since the medication is available in a prefilled syringe labeled 50 mg/2 mL, we need to administer 2 mL to obtain the desired dose of 25 mg.

Therefore, the nurse should administer 1.0 mL of etanercept.

Correct Answer is ["2"]

Explanation

First, let's convert grams to milligrams:

0.1 grams x 1000 mg/gram = 100 mg

Then, set up a proportion:

x tablets / 150 mg = 1 tablet / 100 mg

Cross-multiply:

100x = 150

Solve for x:

x = 150 / 100

x = 1.5

Since we cannot administer a fraction of a tablet, we round up to the nearest whole number.

Therefore, the nurse should administer 2 tablets of secobarbital.

Correct Answer is ["40"]

Explanation

Calculating the Inamrinone Infusion Rate

Step 1: Convert weight to kilograms:

183 lbs x (1 kg / 2.20462 lbs) ≈ 83.0 kg

Step 2: Calculate the desired dose rate in mcg/minute:

8 mcg/kg/minute x 83.0 kg ≈ 664 mcg/minute

Step 3: Calculate the concentration of inamrinone in the IV solution:

0.1 grams/100 mL = 100 mg/100 mL = 1 mg/mL

Step 4: Calculate the infusion rate in mL/hour:

First, convert mcg to mg:

664 mcg x (1 mg / 1000 mcg) = 0.664 mg/minute

Then, set up a proportion:

x mL/hour / 0.664 mg/minute = 60 minutes/hour / 1 mg/mL

Cross-multiply and solve for x:

x mL/hour = 0.664 mg/minute x 60 minutes/hour / 1 mg/mL

x mL/hour ≈ 40 mL/hour

Therefore, the nurse should program the infusion pump to deliver approximately 40 mL/hour.
