In what sequence should the nurse prepare the dose of insulin for a client whose finger stick glucose is 210 mg/dl and is receiving a sliding scale dose of short-acting insulin before breakfast?

  • A. Clean the vial's rubber stopper with an alcohol swab, withdraw the correct dose of insulin, and then inject air equal to the insulin dose into the vial.
  • B. Inject air equal to the insulin dose into the vial, withdraw the correct dose of insulin, and then clean the vial's rubber stopper with an alcohol swab.
  • C. Withdraw the correct dose of insulin, inject air equal to the insulin dose into the vial, and then clean the vial's rubber stopper with an alcohol swab.
  • D. Clean the vial's rubber stopper with an alcohol swab, inject air equal to the insulin dose into the vial, and then withdraw the correct dose of insulin.
Correct Answer: A

Rationale: The correct sequence for preparing a dose of insulin involves ensuring proper aseptic technique. First, clean the vial's rubber stopper with an alcohol swab to prevent contamination. Second, withdraw the correct dose of insulin to be administered. Lastly, inject air equal to the insulin dose into the vial to maintain proper pressure for withdrawing the medication. This sequence ensures the medication is prepared safely and accurately. Choice A is correct as it follows this sequence. Choices B, C, and D present incorrect sequences that may compromise patient safety by not following the correct aseptic technique. Choice B injects air into the vial before withdrawing insulin, which is incorrect. Choice C reverses the order of withdrawing insulin and injecting air. Choice D withdraws the insulin before injecting air, which can affect the pressure inside the vial and lead to inaccurate dosing.
