A nurse is preparing to administer diclofenac sodium 200 mg PO daily in equally divided doses every 6 hours. How many mg 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.)
The Correct Answer is ["50"]
If the daily dose is 200 mg and it is to be given in equally divided doses every 6 hours, then we need to
calculate the amount per dose:
200 mg ÷ 4 doses = 50 mg per dose

Correct Answer is C
Explanation
c) Choose the same day of each week to take this medication.
The nurse should interpret the prescription for alendronate 70 mg PO once per week upon waking to be taken 30 min before food, fluids, or medication with a client who has osteoporosis as instructing the client to choose the same day of each week to take the medication. This will help to ensure that the medication is taken consistently and at the appropriate time.
Taking the medication at 1800, 30 min after the evening meal (option A) is not consistent with the prescription, which specifies that the medication should be taken upon waking and before food, fluids, or other medications. Over-the-counter oral preparations can be taken with this medication (option B) is not accurate; the prescription specifies that alendronate should be taken 30 min before other medications. The client can return to bed after taking the medication, but before eating (option D) is not consistent with the prescription, which specifies that the client should remain upright for 30 min after administration.

Correct Answer is ["0.9 mL"]
Explanation
First, you need to convert the client's weight from pounds to kilograms. There are approximately 2.2 pounds in 1 kilogram, so 99 lb / 2.2 = 45 kg. The dose of morphine is 0.2 mg/kg, so for a client who weighs 45 kg, the dose would be 0.2 mg/kg * 45 kg = 9 mg. To calculate the number of mL the nurse should administer, you need to divide the dose of morphine (9 mg) by the concentration of the morphine injection (10 mg/mL). This gives you 9 mg / (10 mg/mL) = 0.9 mL. When rounded to the nearest tenth, this remains
0.9 mL. So, the nurse should administer 0.9 mL of morphine injection.
