Correct Answer is ["200"]
Explanation
Determine the total volume to be infused.
The nurse is preparing to administer 100 mL of ceftriaxone sodium in dextrose 5% in water.
Calculate the infusion rate in mL/hr.
The infusion time is 30 minutes, which is equivalent to 30/60 = 0.5 hours.
Infusion rate = Total volume / Infusion time = 100 mL / 0.5 hr = 200 mL/hr
Correct Answer is ["0.8"]
Explanation
Determine the desired dose.
The nurse needs to administer 150 mg of the antibiotic.
Calculate the available dose per mL.
The available antibiotic is 2 g/10 mL. This means that each mL of the solution contains 2 g / 10 mL = 0.2 g = 200 mg of the antibiotic.
Calculate the volume to be administered.
Volume = Desired dose (mg) / Concentration (mg/mL) = 150 mg / 200 mg/mL = 0.75 mL
Round the volume to the nearest tenth.
Volume = 0.8 mL
