Dosage
Route
Medication
Time/frequency
The Correct Answer is C
Choice A reason: This is incorrect because the dosage is given in the prescription as 500 mg, which indicates the amount of the drug to be administered.
Choice B reason: This is incorrect because the route is given in the prescription as PO, which stands for per os or by mouth, which indicates how the drug is to be administered.
Choice C reason: This is correct because the medication is not given in the prescription, which is the name of the drug to be administered. The nurse should ask the provider to clarify the medication name and spell it out if necessary.

Correct Answer is B
Explanation
Choice A reason: This is incorrect because the nurse should inject air into the NPH insulin vial after injecting air into the regular insulin vial. This prevents contamination of the regular insulin with the NPH insulin.
Choice B reason: This is correct because the nurse should inject air into the regular insulin vial first, then into the NPH insulin vial, before withdrawing the regular insulin. This equalizes the pressure in the vials and facilitates the withdrawal of the insulin.
Choice C reason: This is incorrect because the nurse should not replace the needle for withdrawal with a safety needle. The same needle should be used for injecting air and withdrawing insulin from both vials.
Choice D reason: This is incorrect because the nurse should withdraw 10 units of insulin from the regular insulin vial after injecting air into both vials. This prevents mixing of the NPH insulin with the regular insulin in the vial.
Correct Answer is B
Explanation
Choice A reason: Insulin glargine is not the type of insulin to use for diabetic ketoacidosis, as it is a long-acting insulin that has a duration of 24 hours and no peak effect. It is used to provide basal insulin coverage and prevent hyperglycemia.
Choice B reason: Regular insulin is the type of insulin to use for diabetic ketoacidosis, as it is a short-acting insulin that has an onset of 30 to 60 minutes and a peak of 2 to 4 hours. It is used to lower the blood glucose level rapidly and correct the acidosis.
Choice C reason: Insulin detemir is also not the type of insulin to use for diabetic ketoacidosis, as it is a long-acting insulin that has a duration of 12 to 24 hours and no peak effect. It is also used to provide basal insulin coverage and prevent hyperglycemia.
Choice D reason: NPH insulin is also not the type of insulin to use for diabetic ketoacidosis, as it is an intermediate-acting insulin that has an onset of 2 to 4 hours and a peak of 4 to 12 hours. It is used to provide intermediate insulin coverage and prevent hyperglycemia.
