Questions and Answers

A patient with type 2 diabetes mellitus is prescribed regular insulin (Humulin R) as part of a basal-bolus regimen. The patient's HbA1c is currently 7.9%. Following the initial dose adjustment protocol, the patient experiences an episode of nocturnal hypoglycemia. Which of the following is the MOST appropriate next step, considering the outlined dosage adjustment guidelines?

Increase the regular insulin dose by 1 to 2 units or 10% to 15% twice weekly to achieve further glycemic control, as the HbA1c target has not yet been reached.

Reduce the basal insulin dose by 4 units or 10% of basal dose, as the initial HbA1c is less than 8%, and the patient is experiencing hypoglycemia.

Maintain the current regular insulin dose and administer a supplementary dose of long-acting insulin at bedtime to stabilize nocturnal glucose levels.

Reduce both the regular insulin and basal insulin doses by 10% to 20% due to the occurrence of hypoglycemia while closely monitoring blood glucose levels. (correct)

A hospital pharmacist is preparing an intravenous infusion of Novolin R for a patient experiencing severe hyperglycemia. The pharmacist needs to prepare a solution containing a specific concentration of insulin in a compatible infusion fluid. Which of the following infusion fluids is LEAST suitable for preparing this IV insulin infusion, considering the stability guidelines for Novolin R?

Lactated Ringer's solution (correct)

10% dextrose with 40 mmol/L potassium chloride

0.9% sodium chloride

5% dextrose

A diabetes educator is instructing a patient on the proper technique for mixing Humulin R and Humulin N insulin. Which of the following statements BEST reflects the correct procedure that should be emphasized to the patient?

To ensure accurate dosing, it is acceptable to draw Humulin N into the syringe first, followed by Humulin R, without any specific time constraints for the injection.

Vigorously shake the mixture of Humulin R and Humulin N to ensure uniform distribution before injecting subcutaneously into the abdomen.

Humulin R and Humulin N can be mixed in any order, provided the injection is administered within one hour of mixing to maintain insulin stability.

Always draw Humulin R (clear) into the syringe first, followed by Humulin N (cloudy), and inject the mixture immediately to prevent alterations in insulin activity. (correct)

A healthcare provider is reviewing a patient's insulin administration technique. The patient reports consistently using the same abdominal site for subcutaneous injections of Novolin R. What potential complication is MOST associated with repeated injections at the same site, and how should the healthcare provider advise the patient to mitigate this risk?

<p>Increased risk of lipohypertrophy; advise the patient to rotate injection sites within the same region or different regions to maintain consistent absorption. (D)</p> Signup and view all the answers

A patient is prescribed both Novolin R and Novolin N. They ask how to draw up the dose correctly. Assuming a dose of 5 units of Novolin R and 10 units of Novolin N is required, what is the correct procedure?

<p>Inject 10 units of air into the Novolin N vial, then 5 units of air into the Novolin R vial. Withdraw 5 units of Novolin R, then withdraw 10 units of Novolin N. (B)</p> Signup and view all the answers
