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 ["2"]

Explanation

To calculate the dosage of diazepam, 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 10 mg, H is 5 mg/mL, and Q is 1 mL.

Plugging these values into the formula, we get:

10 mg / 5 mg/mL x 1 mL = 2 mL

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

Correct Answer is ["100"]

Explanation

To determine the number of doses in the vial, we can use the information provided on the label. The vial contains 10 mL of insulin glargine, and each mL has a concentration of 100 units.

Number of units in the vial = Concentration * Volume

Number of units in the vial = 100 units/mL * 10 mL

Number of units in the vial = 1000 units

Therefore, the vial contains 1000 units of insulin glargine. Since the client is to receive 10 units per dose, we can calculate the number of doses:

Number of doses = Total units in the vial / Units per dose

Number of doses = 1000 units / 10 units/dose

Number of doses = 100 doses

So, the vial contains 100 doses of insulin glargine.
