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.)
Answer and Explanation

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 ["0.1"]

Explanation

The nurse is to administer 100 mcg of cyanocobalamin.

Please note that 1 mg is equivalent to 1000 mcg,

so the concentration of the medication is 1000 mcg/mL.

Therefore, the volume of medication to administer is:

100mcg / 1000mcg/mL ​= 0.1mL

So, the nurse should administer 0.1 mL of cyanocobalamin

Correct Answer is ["1.5"]

Explanation

Here's how to calculate the number of levothyroxine tablets the nurse should administer:

1. We know:

Prescribed dose: 0.075 mg of levothyroxine (given)

Tablet strength: 50 mcg per tablet (given on the medication label)

2. We need to find:

Number of tablets to administer

3. Calculation:

To find the number of tablets, divide the prescribed dose (in milligrams) by the strength of each tablet (in milligrams).

Number of tablets = Prescribed dose (mg) / Tablet strength (mg/tablet)

Number of tablets = 0.075 mg / 50 mcg/tablet

Important note: We need to convert the tablet strength from mcg to mg for consistency in units. Remember, 1 mg is equal to 1000 mcg.

Tablet strength (mg/tablet) = 50 mcg/tablet / 1000 mcg/mg

Tablet strength (mg/tablet) = 0.05 mg/tablet

Now, plug in the converted values:

Number of tablets = 0.075 mg / 0.05 mg/tablet

Number of tablets = 1.5 (round to nearest tenth as requested)

Therefore, the nurse should administer 1.5 tablets.
