A nurse is preparing to administer metronidazole 7.5 mg/kg via intermittent IV bolus to a client who weighs 212 lb. Available is metronidazole 500 mg/100 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["145"]
To calculate the dose of metronidazole for a client who weighs 212 lb, the nurse needs to convert the weight to kilograms and multiply it by the prescribed dose of 7.5 mg/kg.
One kilogram is equal to 2.2 lb, so the client's weight in kilograms is 212/2.2 = 96.36 kg. The dose of metronidazole in milligrams is 96.36 x 7.5 = 722.7 mg.
The nurse needs to find out how many mL of the available solution contain this amount of metronidazole.
The available solution has a concentration of 500 mg/100 mL, so the nurse can use a proportion to solve for the volume: 500/100 = 722.7/x.
Cross-multiplying and solving for x gives x = 722.7 x 100 / 500 = 144.54 mL.
The nurse should round the answer to the nearest whole number, so the final answer is 145 mL.
The nurse should administer 145 mL of metronidazole via intermittent IV bolus to the client.

Correct Answer is ["1.5"]
Explanation
To calculate the number of tablets to administer, you can use the following calculation:
Number of tablets = Desired dose (mg) / Tablet strength (mg per tablet)
Number of tablets = 15 mg / 10 mg per tablet
Number of tablets = 1.5 tablets
Correct Answer is ["48"]
Explanation
To calculate how many milliliters (ml) of gentamicin to administer, follow these steps:
Calculate the client's weight in kilograms: Weight in kilograms = Weight in pounds / 2.2
Weight in kilograms = 210 lb / 2.2 Weight in kilograms ≈ 95.45 kg
Determine the dose based on the weight: Dose = 5 mg/kg × Weight in kilograms Dose = 5 mg/kg × 95.45 kg Dose ≈ 477.25 mg
Check the concentration of the available gentamicin: Concentration = 10 mg/mL
Calculate the volume (ml) to administer: Volume (ml) = Dose (mg) / Concentration (mg/ml) Volume (ml) = 477.25 mg / 10 mg/ml Volume (ml) ≈ 47.73 ml
Rounded to the nearest whole number, the nurse should administer approximately 48 ml of gentamicin.
