A nurse is preparing to administer dobutamine 5mcg/kg/min by continuous IV infusion to client who weigh 250 lb. Available is dobutamine 250 mg in dextrose 5% in water 250 mL. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to nearest whole number. Use a leading zero if it applies, do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["34"]

Convert the Client's Weight from Pounds to Kilograms:

1 kg = 2.205 lbs

Weight in kg = 250 lbs / 2.205 lbs/kg

Weight in kg ≈ 113.38 kg

Calculate the Dobutamine Dose in mcg/min:

Dose = 5 mcg/kg/min x 113.38 kg

Dose ≈ 566.9 mcg/min

Convert the Dobutamine Dose from mcg/min to mg/min:

1 mg = 1000 mcg

Dose in mg/min = 566.9 mcg/min / 1000 mcg/mg

Dose in mg/min ≈ 0.5669 mg/min

Calculate the Dobutamine Dose in mg/hr:

Dose in mg/hr = 0.5669 mg/min x 60 min/hr

Dose in mg/hr ≈ 34.014 mg/hr

Calculate the Infusion Rate in mL/hr:

Available concentration = 250 mg / 250 mL = 1 mg/mL

Infusion Rate (mL/hr) = Dose in mg/hr / Concentration (mg/mL)

Infusion Rate (mL/hr) = 34.014 mg/hr / 1 mg/mL

Infusion Rate (mL/hr) ≈ 34.014 mL/hr

Round to the Nearest Whole Number:

34 mL/hr

Correct Answer is ["0.2"]

Explanation

Convert the Client's Weight from Pounds to Kilograms:

1 kg = 2.205 lbs

Weight in kg = 138 lbs / 2.205 lbs/kg

Weight in kg ≈ 62.585 kg

Calculate the Total Dose of Darbepoetin Needed:

Dose = 0.75 mcg/kg x 62.585 kg

Dose ≈ 46.93875 mcg

Calculate the Volume of Darbepoetin to Administer:

Available concentration = 60 mcg/0.3 mL

To simplify, find the concentration per 1 mL: 60 mcg / 0.3 mL = 200 mcg/mL

Volume (mL) = Desired dose (mcg) / Available concentration (mcg/mL)

Volume (mL) = 46.93875 mcg / 200 mcg/mL

Volume (mL) ≈ 0.23469 mL

Round to the Nearest Tenth:

0.2 mL

A. A total 62.5 mL is available in this dose B. This medication can be administered IM only C. This medication should be protected from light D. The medication is effective for 7 days after reconstitution

Correct Answer is C

Explanation

A. A total 62.5 mL is available in this dose: The label states that each mL of the reconstituted solution contains 62.5 mg of methylprednisolone. However, the total volume available depends on the reconstitution process, and this option does not directly match the provided information.

B. This medication can be administered IM only: The label clearly states that the medication can be given both intramuscularly (IM) and intravenously (IV), making this option incorrect.

C. This medication should be protected from light: The label explicitly instructs to protect the medication from light, confirming this as the correct answer.

D. The medication is effective for 7 days after reconstitution: The label specifies that the medication should be used within 48 hours after reconstitution, not 7 days.
