Draw up one-half of the regular insulin followed by one-half of the NPH insulin and repeat.
The Correct Answer is C
When mixing regular and NPH insulin, it is important to follow the correct steps to ensure proper administration. The general rule is to inject air into the NPH vial, then inject air into the regular vial, draw up the regular insulin, and then draw up the NPH insulin¹.
A. Drawing up the NPH insulin first would be incorrect because it could contaminate the regular insulin with NPH insulin.
B. Drawing up one-half of each insulin at a time would be incorrect because it could result in an inaccurate dosage.

Explanation
Preventing medication errors is a crucial aspect of nursing practice to ensure patient safety. Here are the explanations for the correct options:
b. Know the recommended dose range for the drug: It is essential for nurses to be knowledgeable about the recommended dose range for the medications they administer. Understanding the appropriate dosages helps in identifying any potential errors or discrepancies.
d. Question a drug dose that appears incorrect: If a nurse comes across a drug dose that seems incorrect or questionable, it is important to clarify and verify the dosage with the prescribing healthcare provider or pharmacist. This helps to prevent the administration of potentially harmful doses.
e. Recalculate the drug dosage if in doubt: If a nurse has doubts or uncertainties about the calculated drug dosage, it is crucial to double-check the calculations and recalculate to ensure accuracy. Being cautious and thorough in dosage calculations reduces the risk of medication errors.
a. Ask the charge nurse to administer the medication: While it is always advisable to seek guidance or clarification from senior nurses or charge nurses, the responsibility of administering medications lies with the nurse who has the knowledge and training to do so. Depending solely on the charge nurse to administer medications may not be practical or feasible in all situations.
c. Calculate all drug dosages by body surface area: Calculating drug dosages based on body surface area is necessary for certain medications, especially those with narrow therapeutic ranges or when administering chemotherapy drugs. However, it is not applicable to all medications. The method of dosage calculation varies depending on the medication and prescribed dosage regimen.
Therefore, the correct actions a nurse should take to prevent medication errors are knowing the recommended dose range for the drug, questioning a drug dose that appears incorrect, and recalculating the drug dosage if in doubt.
Correct Answer is B
Explanation
To calculate the rate at which the nurse should set the IV pump to deliver the LR infusion, we need to divide
the total volume (500 ml) by the total time (2 hours).
500 ml / 2 hours = 250 ml/hr
Therefore, the nurse should set the IV pump to deliver the LR infusion at a rate of b. 250 mL/hr.
a. 100 mL/hr: This rate is too low and would result in the infusion taking longer than the prescribed 2 hours.
c. 500 mL/hr: This rate is too high and would result in the infusion being delivered faster than the prescribed 2 hours.
d. 1000 mL/hr: This rate is even higher than the total volume of the infusion divided by the total time. It
would deliver the infusion at a significantly faster rate than intended.
Therefore, the correct rate at which the nurse should set the IV pump to deliver the LR infusion is b. 250 mL/hr, as it ensures that the infusion is delivered over the prescribed 2-hour timeframe
