The nurse is caring for a client with a serum blood glucose of 855 mg/dL who is to receive a continuous infusion of prescribed regular insulin 15 units/hr, IV. The pharmacy delivers regular insulin as 100 units in 100 ml of normal saline. How many milliliters per hour should the nurse administer to the client? Enter numeric value only.

Answer and Explanation

The Correct Answer is ["15"]

The desired insulin infusion rate is 15 units per hour.
The concentration of the insulin solution is 100 units in 100 mL.
This means there is 1 unit of insulin in every 1 mL of the solution (100 units ÷ 100 mL = 1 unit/mL).
To find the milliliters per hour to administer, we need to deliver 15 units per hour, and since there is 1 unit per mL, the flow rate will be: 15 units/hr ÷ 1 unit/mL = 15 mL/hr

Correct Answer is A

Explanation

A. In type 1 diabetes, the pancreas either does not produce any insulin or produces very little insulin. Insulin is necessary to help regulate blood sugar levels by allowing glucose to enter cells. In type 2 diabetes, the body may not respond to insulin effectively (insulin resistance), or the pancreas may not produce enough insulin to meet the body's needs. Either way, insulin production or function is impaired, leading to elevated blood sugar levels.
B. The pancreas does not break down glycogen. Instead, the liver breaks down glycogen into glucose when blood sugar is low. The pancreas's role in diabetes is primarily related to insulin production or secretion, not the breakdown of glycogen.
C. Glucagon is a hormone produced by the pancreas that signals the liver to release glucose when blood sugar is low. In diabetes, the issue is typically with insulin production or the body’s response to insulin, not an overproduction of glucagon.
D. This statement is confusing. The liver does not absorb insulin. In type 2 diabetes, the problem is typically insulin resistance, meaning the body’s cells, including those in the liver, do not respond properly to insulin. In type 1 diabetes, the issue is a lack of insulin production.

Correct Answer is ["0.5"]

Explanation

First, determine how many milligrams are in 1 mL. We can do this by dividing the total milligrams by the total milliliters: 24 mg ÷ 2 mL = 12 mg/mL

Now we know that each milliliter of the solution contains 12 mg of sumatriptan.

To find the volume needed for a 6 mg dose, we need to figure out how many times 12 mg goes into 6 mg: 6 mg ÷ 12 mg/mL = 0.5 mL
