3. The insulin order reads, "Check blood glucose levels before meals and at bedtime. For every 5 mg/dL over 150, give one unit of Regular Humulin insulin, subcutaneously." The patient's blood glucose level at 11:30, before lunch, was 203 mg/dL. In units, how much insulin will the nurse will give?

203 mg/dL is 53 mg/dL more than 150 mg/dL (203 – 150)
53 / 5 units = 10.6
One cannot administer “0.6” of a unit, so the answer is 10 units.

Explanation

203 mg/dL is 53 mg/dL more than 150 mg/dL (203 – 150)
53 / 5 units = 10.6
One cannot administer “0.6” of a unit, so the answer is 10 units.

During times of illness, patients should increase their insulin dosage by 25%.

When mixing insulins, the cloudy (such as NPH) insulin should be drawn up into the syringe first.

When mixing insulins, the clear (such as Regular) insulin should be drawn up into the syringe first.

If mixing insulins in one syringe, the clear (Regular) insulin should always be drawn up in to the syringe first. Patients should always rotate injection sites and should notify their physician if they become ill. Patients should never adjust their own insulin doses!

Explanation

If mixing insulins in one syringe, the clear (Regular) insulin should always be drawn up in to the syringe first. Patients should always rotate injection sites and should notify their physician if they become ill. Patients should never adjust their own insulin doses!

19. When starting a patient's drug therapy with corticosteroids, the nurse is aware that some drug classes can have adverse interactions with corticosteroids, such as

Nonsteroidal antiinflammatory drugs.

Antibiotics.
