Which of the following metric prefixes corresponds to '1/1,000th' of the base unit?

A. Increase the insulin dose to compensate for reduced absorption: Increasing the dose without addressing the site problem may lead to unpredictable absorption and risk of hypoglycemia once the site heals.

B. Reassure the patient that this is normal: While minor irritation can occur, redness may indicate inflammation or early infection. Dismissing it without assessment could delay necessary treatment.

C. Change the infusion site and assess for signs of infection: The first priority is to stop using the affected site to prevent further irritation or infection. Assessing the area ensures early detection and management of potential complications.

D. Apply a warm compress to the site: Applying heat without evaluating the cause may worsen inflammation or mask infection. The site should first be assessed and the infusion moved.

A. Insulin glargine: Insulin glargine is a long-acting basal insulin with no pronounced peak, used to maintain baseline glucose control. It is not intended for rapid correction of postprandial glucose elevations or administration immediately before meals.

B. NPH insulin: NPH insulin is an intermediate-acting insulin with an onset of 1 to 2 hours and a pronounced peak several hours later. Its timing does not align with immediate postprandial glucose rises.

C. Insulin lispro: Insulin lispro is a rapid-acting insulin with an onset of approximately 10 to 15 minutes, making it ideal for administration shortly before meals. It effectively controls postprandial glucose spikes by matching insulin action with carbohydrate absorption.

D. Regular insulin: Regular insulin has an onset of 30 to 60 minutes and is typically administered 30 minutes before meals. It does not act quickly enough to optimally manage glucose levels when given 15 minutes prior to eating.
