A nurse is preparing to administer phenytoin 300 mg PO every 12 hr to a client who has a seizure disorder. Available is phenytoin oral suspension 125 mg/5 mL. How many mL should the nurse administer per dose? (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 ["12"]

To calculate the dose of phenytoin oral suspension for a client with a seizure disorder, the nurse needs to use the following formula:

Dose (mL) = Ordered dose (mg) / Concentration (mg/mL)

In this case, the ordered dose is 300 mg and the concentration is 125 mg/5 mL. Therefore, the dose in mL is:

Dose (mL) = 300 mg / (125 mg/5 mL)

Dose (mL) = 300 mg x (5 mL/125 mg)

Dose (mL) = 12 mL

The nurse should round the answer to the nearest whole number, which is 12 mL. The nurse should administer 12 mL of phenytoin oral suspension every 12 hours to the client.

Correct Answer is ["2"]

Explanation

To give a loading dose of ketorolac 30 mg IM, the nurse needs to calculate the volume of the injection solution.

The solution has a concentration of 15 mg/mL, which means that every 1 mL contains 15 mg of ketorolac.

To find the volume, the nurse can use the formula: volume = dose / concentration. Plugging in the values, we get: volume = 30 mg / 15 mg/mL = 2 mL.

Therefore, the nurse should administer 2 mL of ketorolac injection for a loading dose.

A. Administer the medication twice daily. B. Administer the medication as needed for pain. C. Administer the medication 2 hr after meals. D. Administer a loading dose of 100 mg PO. E. Administer the medication with a snack.

Correct Answer is ["D","E"]

Explanation

A. Administer the medication twice daily. - No, the prescription states 50 mg PO TID (three times a day), not twice daily.

B. Administer the medication as needed for pain. - No, the prescription specifies a scheduled regimen, not PRN (as needed).

C. Administer the medication 2 hours after meals. - No, the prescription advises taking it with food, not after meals.

D. Administer a loading dose of 100 mg PO. - Yes, the initial dose is 100 mg PO now.

E. Administer the medication with a snack. - Yes, the prescription advises taking it with food, so administering it with a snack aligns with this instruction.
