Explanation
Step 1: Identify the given information:
Volume of the solution: 125 mL
Infusion time: 15 minutes
Step 2: Convert the infusion time to hours:
15 minutes = 15/60 hours = 0.25 hours
Step 3: Calculate the infusion rate in mL/hr:
Infusion rate = Volume / Time
Step 4: Substitute the values:
Infusion rate = 125 mL / 0.25 hr
Step 5: Calculate the result:
Infusion rate = 500 mL/hr
Correct Answer is ["2.5"]
Explanation
Identify the given information:
Dose of cefazolin: 835 mg
Concentration of cefazolin: 330 mg/mL
Calculate the volume of cefazolin to be administered:
Volume = Dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume = 835 mg / 330 mg/mL
Calculate the result:
Volume ≈ 2.53 mL
Round the answer to the nearest tenth:
Volume ≈ 2.5 mL
