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 C

Explanation

A. Methimazole (Tapazole) 15 mg, PO, now and every 4 hours is an appropriate treatment for thyroid storm. Methimazole is an antithyroid medication that inhibits the synthesis of thyroid hormones and helps control the symptoms of thyroid storm.
B. Applying humidified oxygen as needed is appropriate because clients in thyroid storm can develop respiratory distress due to high metabolic demands. Providing humidified oxygen can help maintain adequate oxygenation.
C. Aspirin is contraindicated in thyroid storm. It can increase the release of thyroid hormones from the thyroid gland and may also increase the risk of severe complications like bleeding. Furthermore, aspirin can interfere with the binding of thyroid hormones to proteins, exacerbating the condition. Instead, acetaminophen (Tylenol) should be used to reduce fever in thyroid storm.
D. This is an appropriate intervention to manage hyperthermia, which is a common symptom of thyroid storm. A hypothermia mattress can help reduce the client's elevated body temperature in a controlled manner

A. 30 minutes before meals B. 10 minutes before meals C. 2 hours before meals D. 1 hour before meals

Correct Answer is B

Explanation

A. Lispro (Humalog) is a rapid-acting insulin, and it should typically be administered about 15 minutes before or right after a meal. Administering it 30 minutes before a meal would be too early for optimal control of blood sugar levels.
B. Lispro is a rapid-acting insulin, and it is generally administered 10 to 15 minutes before a meal. This timing allows the insulin to start working quickly to manage the rise in blood glucose after eating.
C. Administering lispro 2 hours before a meal would not align with the expected timing of its action and could result in suboptimal blood glucose control.
D. While rapid-acting insulin like lispro works quickly, administering it 1 hour before a meal is not ideal. It’s best to administer it closer to the time of the meal to match the peak of insulin activity with the rise in blood sugar from the meal.
