A nurse is preparing to administer amoxicillin 300 mg PO. The amount lable is amoxicillin oral solution 250 mg/5 mL. How many mL should the nurse administer? (Hound the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
10 mL
6 mL
5 ml
7 mL
The Correct Answer is B
Given:
Ordered dose of amoxicillin: 300 mg
Concentration of amoxicillin oral solution: 250 mg/5 mL
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
300 mg / Volume = 250 mg/5 mL
Step 3: Solve for the unknown volume:
Volume = 300 mg / (250 mg/5 mL)
Volume = 300 mg x (5 mL / 250 mg)
Volume = 6 mL

Correct Answer is A
Explanation
Given:
Volume of fluid: 100 mL
Infusion time: 45 minutes
Step 1: Convert infusion time to hours:
Infusion time (hr) = 45 min / 60 min/hr
Infusion time (hr) = 0.75 hr
Step 2: Calculate the infusion rate in mL/hr:
Flow rate (mL/hr) = Volume (mL) / Infusion time (hr)
Flow rate (mL/hr) = 100 mL / 0.75 hr
Flow rate (mL/hr) = 133.3333333 mL/hr
Step 3: Round to the nearest whole number:
Flow rate (mL/hr) ≈ 133 mL/hr
Correct Answer is C
Explanation
Given:
Volume of fluid: 100 mL
Infusion time: 30 minutes
Drop factor: 60 gtt/mL
Formula:
Flow rate (gtt/min) = (Volume (mL) / Time (min) x Drop factor (gtt/mL)
Step 1: Calculate the infusion rate in mL/min:
Infusion rate (mL/min) = Volume (mL) / Time (min)
Infusion rate (mL/min) = 100 mL / 30 min
Infusion rate (mL/min) = 3.33 mL/min
Step 2: Calculate the flow rate in gtt/min:
Flow rate (gtt/min) = Infusion rate (mL/min) x Drop factor (gtt/mL)
Flow rate (gtt/min) = 3.33 mL/min x 60 gtt/mL
Flow rate (gtt/min) = 200 gtt/min
