The nurse receives an order for regular insulin IV at 12 units/hour for a client with diabetic ketoacidosis. The concentration is insulin 100 units in 250 mL of 0.9% NS. How many milliliters per hour should the IV pump be programmed for? Round your answer to the nearest whole number. Enter numeric value only

Answer and Explanation

The Correct Answer is ["30"]

12 units of insulin should be delivered every hour.
In 250 mL of the IV solution, there are 100 units of insulin.
If 100 units are in 250 mL, then to find the volume for 1 unit, we divide the total volume by the total units: 250 mL ÷ 100 units = 2.5 mL/unit
Since we need to deliver 12 units per hour, and each unit is in 2.5 mL, we multiply the desired units per hour by the volume per unit: 12 units/hour × 2.5 mL/unit = 30 mL/hour
Rounding to the nearest whole number, the IV pump should be programmed to deliver 30 mL per hour.

Correct Answer is B

Explanation

A. Bedtime snacks are often recommended for clients using insulin to help prevent nighttime hypoglycemia, especially if they are taking insulin that has a peak action during the night (e.g., NPH insulin).
B. The timing of food intake should not necessarily coincide with the peak action of the insulin. For example, rapid-acting insulins should be given around meal times, but the timing of food isn't strictly tied to the insulin peak. It's more important to match the insulin to meal timing to help with glucose control.
C. When mixing NPH (a longer-acting insulin) and regular insulin (a shorter-acting insulin), the correct technique is to draw up the regular insulin first to avoid contamination of the regular insulin with the NPH insulin, which is cloudy.
D. Educating clients about the signs, symptoms, and management of hypoglycemia is essential to safe insulin therapy.

A. "I will use the first drop of blood for my sample" B. "I will poke in the center of the pad of my finger to obtain a sample for testing" C. "I will apply a cold compress on my fingers if I cannot collect any blood" D. "I will make sure I have clean hands prior to testing"

Correct Answer is D

Explanation

A. It is generally recommended to discard the first drop of blood when testing with a glucometer because it may be diluted with tissue fluid, leading to inaccurate results. The second drop should be used for the sample.
B. The center of the fingertip should be avoided for testing because it contains more nerve endings and can be more painful. It is better to poke the sides of the fingertip for a less painful experience.
C. A cold compress may cause blood vessels to constrict, making it even harder to obtain a blood sample. Gentle massaging of the finger or warming the hands may help with blood flow.
D. It is important to wash hands before testing to ensure that the blood sample is not contaminated with food residues, dirt, or other substances that could affect the accuracy of the glucose reading.
