1A 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 give a patient cetirizine 5 mg PO, the nurse needs to measure the correct amount of liquid medicine. The medicine has a concentration of cetirizine 2.5 mg/5 mL, which means that every 5 mL of liquid contains 2.5 mg of cetirizine.

To find out how many mL of liquid are equivalent to 5 mg of cetirizine, the nurse can use a proportion:

2.5 mg / 5 mL = 5 mg / x mL

Cross-multiplying and solving for x, the nurse gets:

x = (5 mL x 5 mg) / 2.5 mg

x = 10 mL

Therefore, the nurse should administer 10 mL of liquid medicine to give the patient cetirizine 5 mg PO.

Correct Answer is ["1.1"]

Explanation

To calculate the dosage of cefazolin, the nurse needs to use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity.

In this case, D is 250 mg, H is 225 mg/mL, and Q is 1 mL.

Plugging these values into the formula, we get:

250 mg / 225 mg/mL x 1 mL = 1.11 mL

Therefore, the nurse should administer 1.1 mL of cefazolin IM to the client.

Correct Answer is ["8"]

Explanation

To give the client the correct dose of phenytoin, the nurse needs to calculate the volume of the oral suspension that contains 200 mg of the drug. The formula for this calculation is:

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

The concentration of the oral suspension is 125 mg/5 mL, which means that 1 mL contains 25 mg of phenytoin. Therefore, the nurse can substitute these values into the formula:

Volume (mL) = 200 mg / 25 mg/mL

Volume (mL) = 8 mL

Therefore, the nurse should administer 8 mL of the oral suspension to the client.
