Give Ceclor 45mg/kg/day p.o. in 3 divided doses for a patient who weighs 66 pounds. A 75mL stock medication is labeled Ceclor 125mg/mL. How many mLs would the nurse administer per dose?
Units in mL. (Please record your exact answer)
The Correct Answer is ["3.6"]
- To calculate the dose of Ceclor in mg, multiply the weight in kg by the dosage in mg/kg/day and divide by the number of doses per day.
- To convert pounds to kg, divide by 2.2.
- To calculate the volume of Ceclor in mL, divide the dose in mg by the concentration in mg/mL.
- Convert 66 pounds to kg: 66 / 2.2 = 30 kg
- Calculate the dose of Ceclor in mg: 30 x 45 / 3 = 450 mg
- Calculate the volume of Ceclor in mL: 450 / 125 = 3.6 mL
- The nurse would administer 3.6 mL per dose.

Correct Answer is D
Explanation
Choice A reason:
Taking metronidazole with food can help reduce stomach upset. It is not typically recommended to take on an entirely empty stomach.
Choice B reason:
Metronidazole can cause drowsiness, but taking it at bedtime specifically for this reason is not a standard recommendation. It's more important to focus on avoiding alcohol.
Choice C reason:
Taking an extra dose without specific medical advice is not recommended. It's important to follow the prescribed dosing regimen.
Choice D reason:
Avoiding alcohol while taking metronidazole is crucial. The combination of metronidazole and alcohol can cause severe reactions, including nausea, vomiting, abdominal cramps, headache, and flushing. This interaction can occur for several days after discontinuing metronidazole, so it's essential to abstain from alcohol throughout the course of treatment.
Correct Answer is B
Explanation
Choice A reason:
While lansoprazole can be taken with or without food, it is generally recommended to take it before a meal for optimal effectiveness in reducing stomach acid.
Choice B reason:
This is the correct answer. Taking lansoprazole 30 minutes before breakfast allows it to be most effective in reducing stomach acid production.
Choice C reason:
Taking lansoprazole after lunch may not provide the same level of effectiveness in reducing stomach acid as taking it before a meal.
Choice D reason:
Taking lansoprazole with a bedtime snack may not be as effective in reducing stomach acid as taking it before a meal. Additionally, it is generally recommended to take it in the morning.
