A nurse is preparing to administer cetirizine 5 mg PO. Available is cetirizine 2.5 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["10"]

To administer 5mg of cetirizine with a concentration of 2.5mg/mL, the nurse should indeed administer 10 mL.

Here's the corrected calculation:

Desired dose: 5 mg

Concentration of available cetirizine: 2.5 mg/mL

We can find the volume to administer by dividing the desired dose by the concentration

Volume to administer = Dose / Concentration

= 5 mg / (2.5 mg/mL)

= 2 mL

However, since each milliliter only contains 2.5mg, we need to administer more than 2mL to reach the desired dose of 5mg.

To get to 5mg, we need to administer twice the amount (2 x 2.5mg = 5mg). This translates to:

Total volume to administer = 2 mL/dose x 2 doses

= 10 mL

Therefore, the nurse should administer 10 mL of the cetirizine solution.

Correct Answer is ["2"]

Explanation

The nurse should administer 2 mL of diazepam injection

Here's the calculation:

Desired dose: 10 mg

Concentration of available diazepam: 5 mg/mL

We can find the volume to administer by dividing the desired dose by the concentration and rounding to the nearest whole number:

Volume to administer (rounded) = Dose / Concentration

= 10 mg / (5 mg/mL)

= 2 mL (rounded to nearest whole number)

Therefore, the nurse should administer 2 mL of the diazepam injection.

Correct Answer is ["2"]

Explanation

Here's the breakdown:

Desired dose: 0.5 g (grams)

Conversion:

1 gram (g) is equal to 1000 milligrams (mg).

Therefore, we need to convert the desired dose from grams to milligrams:

Desired dose (mg) = 0.5 g x 1000 mg/g = 500 mg

Available dosage:

Each capsule contains 250 mg of cefaclor.

Calculation of capsules needed:

To find the number of capsules needed, we can divide the desired dose (in milligrams) by the amount of medication in each capsule (rounding to the nearest whole number):

Number of capsules (rounded) = Desired dose (mg) / Medication per capsule

= 500 mg / 250 mg/capsule

= 2 capsules (rounded to nearest whole number)
