The human insulin whose onset of action occurs within ________ minutes is Humalog (Lispro).

A.

60

B.

15

C.

45

D.

30

Answer and Explanation

The Correct Answer is B

A. 60: An onset of action of 60 minutes is characteristic of some types of short-acting insulin (like Regular insulin) but not rapid-acting insulins such as Humalog (Lispro). Rapid-acting insulins are designed to work much faster to cover post-meal glucose excursions.

B. 15: Humalog (insulin lispro) is a rapid-acting insulin analog, with a quick onset of action. Its effects begin within 5 to 15 minutes after subcutaneous injection, making it ideal for administration just before or immediately after a meal to manage the rise in blood glucose.

C. 45: An onset of 45 minutes would be slower than what is expected for a rapid-acting insulin like Humalog. This timeframe is closer to the onset of Regular insulin, which requires administration 30-45 minutes before a meal.

D. 30: While 30 minutes is a common instruction for administering Regular insulin before a meal, it is not the typical onset time for rapid-acting insulins like Humalog (Lispro). Humalog's action begins much sooner, allowing for greater flexibility in meal timing.

Correct Answer is ["200"]

Explanation

Total volume to be infused = 100 mL.

Infusion time in minutes = 30 minutes.

  • Convert the infusion time from minutes to hours.

Infusion time in hours = 30 minutes / 60 minutes/hour

= 0.5 hours.

  • Calculate the flow rate in milliliters per hour (mL/hr).

Flow rate (mL/hr) = Total volume (mL) / Infusion time (hr)

= 100 mL / 0.5 hr

= 200 mL/hr.

Correct Answer is D

Explanation

A. Hyperglycemia occurring on "sick days": Glucagon is not used to treat hyperglycemia. During "sick days," clients with diabetes may experience elevated blood glucose levels, but glucagon is not for managing hyperglycemia. Instead, insulin adjustments are made.

B. Diabetic ketoacidosis: Glucagon is not used to treat diabetic ketoacidosis (DKA). DKA is a severe complication of diabetes often caused by insulin deficiency, and it requires insulin therapy and fluid management to correct the underlying issues.

C. Hyperglycemia from insufficient insulin: Glucagon is not used for hyperglycemia due to insufficient insulin. The treatment for this condition is typically insulin therapy to lower blood glucose levels.

D. Hypoglycemia from insulin overdose: Glucagon is used to treat hypoglycemia caused by an insulin overdose, as it helps to raise blood glucose levels quickly by stimulating the liver to release glucose into the bloodstream. It is essential for managing severe hypoglycemia.
