The nurse is preparing a 50 mL dose of 50% dextrose IV for a patient with insulin shock. What is the appropriate method for administering the medication?
Explanation & Rationale
Choice A rationale Mixing the dextrose in a 50 mL piggyback for a total volume of 100 mL is not the appropriate method for administering the medication. This would dilute the dextrose, reducing its concentration and potentially making it less effective. Choice B rationale Diluting the dextrose in one liter of 0.9% normal saline solution is not the appropriate method for administering the medication. This would significantly dilute the dextrose, reducing its concentration and potentially making it less effective. Choice C rationale Requesting the pharmacist to add the dextrose to a total parenteral nutrition (TPN) solution is not the appropriate method for administering the medication. While dextrose is often a component of TPN solutions, in this case, the patient requires a concentrated dose of dextrose to treat insulin shock. Choice D rationale This is the correct answer. Administering the undiluted dextrose slowly through the currently infusing IV is the appropriate method for administering the medication. This allows for the rapid administration of a concentrated dose of glucose, which is necessary to quickly raise the patient’s blood glucose level in the case of insulin shock.
