A nurse is preparing to administer amoxicillin 30 mg/kg/day divided doses every 12 hr to a toddler who weighs 33 lb. Available is amoxicillin 200 mg/5 mL suspension. How many mL should the nurse administer every 12 hr? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
5 mL
5.6 mL
0.5 mL
6 mL
The Correct Answer is B
Given:
Ordered dose of amoxicillin: 30 mg/kg/day divided every 12 hours
Toddler's weight: 33 lbs
Concentration of amoxicillin suspension: 200 mg/5 mL
Step 1: Convert the toddler's weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Weight in kg = 33 lbs x 0.453592 kg/lb = 14.968 kg
Step 2: Calculate the total daily dose of amoxicillin:
Total daily dose (mg) = Ordered dose (mg/kg/day) x Weight (kg)
Total daily dose (mg) = 30 mg/kg/day x 14.968 kg
Total daily dose (mg) = 449.04 mg/day
Step 3: Calculate the dose per administration:
Since the medication is given every 12 hours, there are 2 administrations per day.
Dose per administration (mg) = Total daily dose (mg) / Number of administrations per day
Dose per administration (mg) = 449.04 mg/day / 2 administrations/day
Dose per administration (mg) = 224.52 mg
Step 4: Calculate the volume to be administered:
Volume (mL) = Dose per administration (mg) / Concentration (mg/mL)
Volume (mL) = 224.52 mg / (200 mg/5 mL)
Volume (mL) = 224.52 mg x (5 mL / 200 mg)
Volume (mL) = 5.613 mL
Step 5: Round to the nearest tenth:
Volume (mL) ≈ 5.6 mL

Correct Answer is D
Explanation
Given:
Ordered dose of Lithium: 300 mg
Available Lithium capsules: 150 mg/capsule
Step 1: Calculate the number of capsules required:
Number of capsules = Desired dose (mg) / Strength of each capsule (mg/capsule)
Number of capsules = 300 mg / 150 mg/capsule
Number of capsules = 2 capsules
Correct Answer is B
Explanation
Given:
Ordered volume of Isomil: 12 oz
Step 1: Determine the volume of Isomil needed for 1/4 strength:
Volume of Isomil for 1/4 strength = Original volume x (1/4)
Volume of Isomil for 1/4 strength = 12 oz x (1/4)
Volume of Isomil for 1/4 strength = 3 oz
Step 2: Calculate the volume of solvent (water) needed:
Solvent volume = Original volume - Volume of Isomil for 1/4 strength
Solvent volume = 12 oz - 3 oz
Solvent volume = 9 oz
Step 3: Convert ounces to milliliters:
1 oz = 29.5735 mL
Solvent volume (mL) = 9 oz x 29.5735 mL/oz
Solvent volume (mL) = 266.1615 mL
Step 4: Round to the nearest whole number:
Solvent volume (mL) ≈ 270 mL
