Question

Calculate the dosage of insulin where necessary, and shade the dosage on the syringe provided. Labels have been provided for some problems. Order: Novolin Regular U-100 5 units subcut and Novolin N U-100 35 units subcut 7:30 \(\mathrm{AM}\).

Short answer

Combine 5 units and 35 units of insulin for a total of 40 units.

Step-by-step solution

Understanding the Medication Order

The medication order specifies administering two types of insulin: Novolin Regular U-100 and Novolin N U-100. The dosages are 5 units and 35 units, respectively, to be given subcutaneously at 7:30 AM.

Calculating the Total Insulin Dosage

Add the dosages of the two insulins to find the total amount of units to be administered. This totals to 5 units (Novolin Regular) + 35 units (Novolin N) = 40 units of insulin.

Preparing the Insulin Syringe

With a U-100 insulin syringe, calculate where to draw the plunger back to administer the correct dosage of insulin. For this order, the syringe needs to be filled to the 40-unit mark, as we have to administer 40 units total.

Shading the Syringe Dosage

On the provided syringe, shade from the bottom up to the 40-unit line to indicate the volume of insulin to be drawn up for the dose as per the order. This visual helps ensure that the correct volume is administered.

Key concepts

Medication Order Interpretation

The first step in administering medication effectively is understanding the medication order. This process involves deciphering instructions from a healthcare provider, ensuring correct dosage and administration.

• The medication order identifies what medication to give, how much to administer, and how it should be given.
• In our exercise, the order is for two types of insulin: Novolin Regular U-100 and Novolin N U-100. These need to be administered subcutaneously, meaning under the skin, at a specific time — 7:30 AM.
• Careful interpretation prevents errors: incorrectly administering insulin can lead to health complications, especially since insulin directly affects blood sugar levels.

Understanding each part of the order is crucial, from the type of insulin to the dosage and time, ensuring safe and effective patient care.

Insulin Types and Administration

Insulin, a hormone crucial in regulating blood sugar, comes in different types that vary in how quickly and how long they work. Understanding these characteristics ensures effective diabetes management.

• Novolin Regular U-100: This is a form of short-acting insulin. It starts working within 30 minutes and lasts around 5-8 hours. It’s used to control blood sugar spikes during meals.
• Novolin N U-100: This is an intermediate-acting insulin. It takes a couple of hours to start working and continues to work for about 12-18 hours, providing a baseline level of insulin.

To administer insulin:

• Use a syringe designed for insulin, often marked with units specific to insulin.
• In the exercise, we're instructed to give both insulins as one dose, which requires accurate measurement and mixing techniques.

Correct administration minimizes risks of hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar), crucial for those managing diabetes.

Syringe Measurement for Medications

Administering the exact dosage of insulin requires precise measurement using a syringe. Insulin syringes come calibrated in units, simplifying the measurement process for consistent dosing.

• A U-100 syringe means 100 units per milliliter. It's specifically designed for insulin administration, marked so that each line represents a specific increment.
• For our exercise, calculate the cumulative dosage of both insulins, which totals to 40 units.
• To measure, draw the insulin into the syringe until the plunger aligns with the 40-unit marking. This ensures all required units are administered accurately.
• Shading the syringe up to the required line can also serve as a double-checking system for the correct dosage.

Using the syringe correctly is critical for effective diabetes management, ensuring patients receive the correct dosage every time.
