A healthcare provider orders atropine sulfate 400 mcg IM as a preoperative medication. The medication is provided as 0.1 mg/mL. How many mL should the nurse administer?
2 mL
3 mL
4 mL
5 mL
The Correct Answer is C
The ordered dose is 400 mcg, which is equal to 0.4 mg..
The medication is provided as 0.1 mg/mL, so to administer 0.4 mg, the nurse needs to give:.
0.4 mg ÷ 0.1 mg/mL = 4 mL.
Therefore, the nurse should administer 4 mL of atropine sulfate.

Correct Answer is A
Explanation
Dextrose 50%, add 1 mL to 4 mL injectable saline. To obtain 5 mL of 10% dextrose, 0.5 mL of the 50% dextrose should be diluted with 4.5 mL of sterile water or normal saline. Therefore, the nurse should add 1 mL of the 50% dextrose to 4 mL of injectable saline to get a final concentration of 10% dextrose in 5 mL. This will give the client the appropriate dose.
Choice B is incorrect because adding 2 mL of the 50% dextrose to 3 mL of saline would give a final concentration of 20%, which is higher than the prescribed concentration of 10%.
Choice C is incorrect because adding 3 mL of the 50% dextrose to 2 mL of saline would give a final concentration of 30%, which is significantly higher than the prescribed concentration of 10%.
Choice D is incorrect because adding 4 mL of the 50% dextrose to 1 mL of saline would give a final concentration of 40%, which is much higher than the prescribed concentration of 10%.
Correct Answer is C
Explanation
The Tylenol 3 medication contains codeine 30 mg and acetaminophen (APAP) 300 mg per tablet.
The physician has ordered Tylenol 3 30 mg every 4-6 hours as needed for pain. Therefore, the nurse should administer 1 tablet (containing 30 mg of codeine and 300 mg of APAP) every 4-6 hours as needed for pain..
It is important to note that the maximum daily dose of acetaminophen is 4,000 mg. Therefore, the nurse should monitor the total daily dose of acetaminophen the patient receives from all sources to ensure it does not exceed 4,000 mg.
