A nurse is preparing to administer dicloxacillin 6.25 mg/kg PO to a child who weighs 14 lb. Available is dicloxacillin 62.5 mg/5 mL. How many ml should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["3.2"]

To calculate the dosage of dicloxacillin to administer to the child, we need to follow these steps

Convert the child's weight from pounds to kilograms:

1 pound (lb) = 0.453592 kilograms (kg)

Child's weight in kg = 14 lb × 0.453592 = 6.35 kg

Determine the dose in mg:

Dosage required = 6.25 mg/kg

Dose = 6.25 mg/kg × 6.35 kg = 39.6875 mg

Determine how many mL of the medication to administer:

The concentration of dicloxacillin is 62.5 mg/5 mL

Using the formula:

Volume (mL)= Dose (mg)/Concentration (mg/mL)

Concentration (mg/mL) = 62.5 mg / 5 mL = 12.5 mg/mL

Volume (mL) = 39.6875 mg / 12.5 mg/mL = 3.175 mL

Round to the nearest tenth:

Volume to administer = 3.2 mL

The nurse should administer 3.2 mL of dicloxacillin.

Correct Answer is ["1"]

Explanation

Let's break down the problem step-by-step:

Step 1: Convert the weight from pounds to kilograms.

We know that 1 kg is approximately 2.205 pounds.
So, to convert 220 pounds to kilograms, we divide by 2.205:
```
220 lb ÷ 2.205 lb/kg ≈ 100 kg
```

Step 2: Calculate the total dose of enoxaparin in mg.

We need to administer 1 mg of enoxaparin per kilogram of body weight.
The client weighs 100 kg, so the total dose is:
```
1 mg/kg × 100 kg = 100 mg
```

Step 3: Determine the volume to administer.

We have enoxaparin 30 mg/0.3 mL available.
To find the volume needed for 100 mg, we can set up a proportion:
```
(30 mg / 0.3 mL) = (100 mg / x mL)
```
Cross-multiplying, we get:
```
30x = 30
```
Solving for x:
```
x = 30 / 30 = 1 mL
```

Therefore, the nurse should administer 1 mL of enoxaparin.

Correct Answer is ["100"]

Explanation

The label on the vial indicates that the insulin glargine has a concentration of 100 units per milliliter (U-100) and the total volume of the vial is 10 mL.

To calculate the total number of units in the vial, you multiply the volume by the concentration:

Totalunits = Volume × Concentration = 10mL×100units/mL = 1000units

Then, to find out how many doses of 10 units each are in the vial,

you divide the total number of units by the number of units per dose:

Numberofdoses = Totalunits/ Unitsperdose

= 1000units /10units per dose

= 100doses

So, the vial contains 100 doses of this medication when administered at 10 units per dose
