What type of insulin would the nurse administer if the fastest therapeutic effects are needed?
Aspart.
Glulisine.
Lispro.
Regular.
The Correct Answer is D
Glulisine is a rapid-acting insulin that has an onset of action of 2 to 5 minutes and peaks in 30 to 90 minutes, making it the fastest among the choices. Some possible explanations for the other choices are:
Choice A. Aspart is also a rapid-acting insulin, but it has a slightly longer onset of action (10 to 20 minutes) and peak time (1 to 3 hours) than glulisine.
Choice B. Lispro is another rapid-acting insulin, but it has a similar onset of action (<15 minutes) and peak time (30 to 90 minutes) as glulisine, so it is not the fastest.
Choice C. Regular is a short-acting insulin that has a much longer onset of action (30 to 60 minutes) and peak time (2 to 4 hours) than glulisine, so it is not suitable for fast therapeutic effects.
Normal ranges for blood glucose levels are 70 to 130 mg/dL before meals and less than 180 mg/dL after meals.
Insulin doses are adjusted based on blood glucose monitoring, carbohydrate intake, physical activity, and other factors.

Correct Answer is C
Explanation
This strategy can help the client read the numbers on the syringe and prepare the correct dose of insulin. A magnifying glass is also an affordable and accessible tool for the client.
Choice A is wrong because preparing a week’s supply of syringes and refrigerating them can affect the potency and sterility of insulin.
It can also increase the risk of errors or confusion.
Choice B is wrong because asking a neighbor to come over every day to prepare the medication can compromise the client’s privacy and independence.
It can also be unreliable and inconvenient for both parties.
Choice D is wrong because changing the client to oral antidiabetics is not possible for type 1 diabetes.
People with type 1 diabetes need to take insulin for life because their pancreas cannot make insulin.
Oral antidiabetics are only effective for people with type 2 diabetes who have functioning pancreatic beta cells
Correct Answer is D
Explanation
Oxygen cannot diffuse rapidly across the membrane to tissues in the eye. This is because diabetic retinopathy is a condition that occurs when high blood sugar levels damage the tiny blood vessels that nourish the retina, the light-sensitive tissue at the back of the eye. As a result, the retina becomes ischemic (lacking oxygen) and tries to grow new blood vessels that are fragile and leaky.
Choice A is wrong because inability of cells in the eye to reproduce is not a cause of diabetic retinopathy.
The retina has a high metabolic rate and needs a constant supply of oxygen and nutrients to function properly.
Choice B is wrong because increase of aqueous humor in the eye is not a cause of diabetic retinopathy.
Aqueous humor is the clear fluid that fills the front part of the eye, not the retina.
An increase of aqueous humor can cause glaucoma, which is a different eye disorder that affects the optic nerve.
Choice C is wrong because decrease of nerve innervations throughout the eye is not a cause of diabetic retinopathy.
Nerve innervations are the connections between nerves and other tissues, such as muscles or glands.
Diabetic retinopathy affects the blood vessels, not the nerves, of the retina.
