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

Here's the calculation:

Desired dose: 10 mg

Concentration of available zolpidem oral spray: 5 mg/spray

To find the number of sprays to administer, we can divide the desired dose by the concentration per spray and round to the nearest whole number:

Number of sprays (rounded) = Desired dose / Concentration per spray

= 10 mg / 5 mg/spray

= 2 sprays (rounded to nearest whole number)

Therefore, the nurse should administer 2 sprays of the zolpidem oral spray.

A. The client can return to bed after taking the medication, but before eating B. Take the medication at 1800, 30 min after the evening meal C. Choose the same day of each week to take this medication. D. Over-the-counter oral preparations can be taken with this medication.

Correct Answer is C

Explanation

A) The client can return to bed after taking the medication, but before eating:
Returning to bed after taking alendronate is not recommended. The client needs to remain upright for at least 30 minutes after taking the medication to prevent esophageal irritation or damage.

B) Take the medication at 1800, 30 min after the evening meal:
Alendronate should be taken in the morning upon waking and at least 30 minutes before any food, fluids, or other medications. Taking it in the evening or after a meal would reduce its effectiveness.

C) Choose the same day of each week to take this medication:
The prescription specifies that alendronate should be taken once per week. Choosing the same day each week ensures consistency and helps maintain the correct dosing schedule, which is crucial for the medication's effectiveness in treating osteoporosis.

D) Over-the-counter oral preparations can be taken with this medication:
Alendronate should be taken alone, and other medications, including over-the-counter preparations, should not be taken simultaneously. This is to avoid any potential interactions that could affect the absorption and efficacy of alendronate.
