A client receives a prescription for amoxicillin 250 mg PO every 8 hours. The client is to take the medication until the bottle is empty. After the nurse reconstitutes the dry powder, how many days will the bottle of medication last? (Enter numerical value only.)
The Correct Answer is ["10"]
First, we need to calculate the total amount of medication that will be administered in a day.
The prescription is for 250 mg every 8 hours, which means three doses per day (since there are 24 hours in a day).
Therefore, the total daily dosage is 250 mg x 3 = 750 mg.
Next, we need to find out how many milligrams are in the entire bottle.
Since each 5 mL contains 250 mg, we can calculate this by setting up a proportion:
(250 mg / 5 mL) = (Total mg / 150 mL)
Solving for Total mg gives us:
Total mg = (250 mg / 5 mL) * 150 mL Total mg = (50 * 150) Total mg = 7500 mg
Now that we know there are a total of 7500 mg in the bottle, we can determine how many days it will last by dividing this number by the total daily dosage:
Days = Total medication in bottle / Daily dosage Days = 7500 mg / (3 doses * 250mg) Days = 7500mg /750mg Days =10
Therefore, the bottle of medication will last for 10 days.

Correct Answer is ["12","000"]
Explanation
Here's the calculation for how many heparin units the client will receive in 12 hours:
Heparin concentration: The concentration of the heparin solution is 20,000 units in 500 mL (given). This translates to 40 units/mL (concentration = total units / volume).
Infusion rate: The client is receiving the solution at a rate of 25 mL/hour (given).
Time: We need to find the total heparin units received over 12 hours.
Calculation:
Find the total volume of the solution infused in 12 hours:
Total volume (mL) = Rate (mL/hour) x Time (hours)
Total volume (mL) = 25 mL/hour x 12 hours
Total volume (mL) = 300 mL
Find the total heparin units delivered in the infused volume:
Total heparin units = Volume of solution (mL) x Concentration (units/mL)
Total heparin units = 300 mL x 40 units/mL
Total heparin units = 12,000 units
Therefore, the client will receive 12,000 units of heparin in 12 hours.
Correct Answer is ["1.20"]
Explanation
First, we need to convert the client’s weight from pounds to kilograms since the dosage is prescribed in mg/kg. We know that 1 kg is approximately 2.20462 pounds. So,
Weightinkg = Weightinpounds / 2.20462 = 132/ 2.20462 ≈ 59.87kg
The prescribed dosage is 1 mg/kg every 12 hours, so the total daily dosage (for 24 hours) in mg would be:
Dailydosageinmg= 2 × (Dosageperkg × Weightinkg) = 2 × (1mg/kg × 59.87kg) ≈ 119.74mg
The medication is available in a concentration of 60 mg/0.6 mL, which simplifies to 100 mg/mL. Therefore, the volume to be administered per day in mL would be:
VolumeinmL=Dailydosageinmg/ Concentrationinmg/mL = 119.74mg / 100mg/mL ≈ 1.20mL
So, the nurse should administer approximately 1.20 mL of enoxaparin per day. Always consult with a healthcare professional for accurate information.
