A nurse is preparing to administer heparin 8,000 units subcutaneous to a client. Available is heparin injection 10,000 units/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["0.8 "]

Given:

  • Desired dose of heparin: 8,000 units
  • Available strength of heparin injection: 10,000 units/mL

First, find out how many milliliters of heparin correspond to the desired dose: Volume (mL) = Desired dose / Concentration

Volume (mL) = 8,000 units / 10,000 units/mL Volume (mL) = 0.8 mL

So, the nurse should administer 0.8 mL of heparin.

Correct Answer is ["1.8 "]

Explanation

Given:

  • Desired dose of ceftriaxone: 75 mg/kg/day
  • Child's weight: 37 lb
  • Available strength of ceftriaxone after reconstitution: 350 mg/mL

First, convert the child's weight from pounds to kilograms: 37 lb ÷ 2.20462 = 16.78 kg (rounded to the nearest hundredth)

The total daily dose of ceftriaxone:

Total daily dose = Desired dose × Child's weight

Total daily dose = 75 mg/kg/day × 16.78 kg Total daily dose ≈ 1258.5 mg

Since the total daily dose is to be divided into two equal doses, each dose would be:

Each dose = Total daily dose / Number of doses per day Each dose = 1258.5 mg / 2

Each dose = 629.25 mg

The milliliters of ceftriaxone correspond to each dose:

Volume (mL) = Dose / Concentration

Volume (mL) = 629.25 mg / 350 mg/mL Volume (mL) ≈ 1.8 mL

So, the nurse should administer approximately 1.8 mL of ceftriaxone per dose.
