A nurse is preparing to administer midazolam 7 mg IM 30 min prior to a procedure. Available is midazolam injection 5 mg/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 ["1.4 "]

Given:

Desired dose of midazolam: 7 mg
Available strength of midazolam injection: 5 mg/mL

The milliliters of midazolam correspond to the desired dose: Volume (mL) = Desired dose / Concentration

Volume (mL) = 7 mg / 5 mg/mL

Volume (mL) = 1.4 mL

So, the nurse should administer approximately 1.4 mL of midazolam.

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.

Correct Answer is ["1"]

Explanation

Client's weight: 220 lb

Desired dose of enoxaparin: 1 mg/kg

Available strength of enoxaparin: 30 mg/0.3 mL

First, convert the client's weight from pounds to kilograms:

220 lb ÷ 2.20462 ≈ 99.79 kg

Now, calculate the desired dose of enoxaparin:

Desired dose = Dosage per kg × Weight Desired dose = 1 mg/kg × 99.79 kg ≈ 99.79 mg 30mg = 0.3ml

Therefore, 99.79mg = 99.79 * 0.3/30

=0.9979

Rounded off to the nearest whole number= 1ml
