A nurse is teaching a client who is newly diagnosed with type 2 diabetes mellitus about insulin therapy. Which of the following insulin combinations should the nurse instruct the client to mix?

Insulin aspart and NPH insulin

Insulin degludec and NPH insulin.

Insulin glargine and insulin detemir

Insulin lispro and regular insulin

Answer and Explanation

The Correct Answer is A

A. Insulin aspart and NPH insulin: Insulin aspart is a rapid-acting insulin, and NPH is an intermediate-acting insulin. These can be mixed in the same syringe to provide both immediate and prolonged glucose control, with aspart covering postprandial spikes and NPH maintaining basal levels.

B. Insulin degludec and NPH insulin: Insulin degludec is an ultra-long-acting insulin and should not be mixed with any other insulin, as mixing can alter its absorption and effectiveness.

C. Insulin glargine and insulin detemir: Both glargine and detemir are long-acting insulins and should not be mixed with any other insulin, as this can interfere with their mechanism of providing a steady release.

D. Insulin lispro and regular insulin: Insulin lispro is a rapid-acting insulin, and regular insulin is short-acting. These insulins should not be mixed because they have different onset and peak times, which can lead to unpredictable glucose control.

Correct Answer is A

Explanation

A. Glucagon 1 mg IM: Glucagon is used to treat severe hypoglycemia when the client is unconscious, having seizures, or unable to take oral glucose. It stimulates glycogen breakdown in the liver, raising blood glucose levels. IM administration is appropriate for rapid effect in an emergency.

B. Continuous IV infusion of regular insulin: Insulin lowers blood glucose levels, which would worsen hypoglycemia. Administering insulin in this situation is inappropriate and could exacerbate the client’s condition.

C. 10 g of oral glucose gel: Oral glucose is suitable for mild to moderate hypoglycemia in a conscious client. However, since the client is experiencing a seizure, they are unable to swallow safely, making this option unsafe.

D. 1 L bolus of 0.45% sodium chloride over 1 hr: Hypoglycemia is not primarily treated with IV fluids unless the client is severely dehydrated. The priority in this case is to correct the low blood glucose level rather than administering hypotonic fluids.

A. "Your provider would not prescribe this treatment if it weren't necessary." B. "Chemotherapy is your best chance for survival." C. "It is your decision whether to continue chemotherapy." D. "Why don't you want to continue treatment?"

Correct Answer is C

Explanation

A. "Your provider would not prescribe this treatment if it weren't necessary.": While the provider recommends treatment based on medical necessity, the decision to continue or discontinue chemotherapy ultimately lies with the client. This response does not acknowledge the client’s autonomy.

B. "Chemotherapy is your best chance for survival.": This response focuses on treatment efficacy rather than addressing the client's emotional and personal concerns. It may also create pressure rather than supporting the client’s decision-making process.

C. "It is your decision whether to continue chemotherapy.": This response is appropriate as it acknowledges the client’s autonomy and right to make healthcare decisions. It validates the client’s concerns while offering support without imposing an opinion.

D. "Why don't you want to continue treatment?": Asking "why" may make the client feel defensive or pressured to justify their decision. A more open-ended approach, such as "Can you tell me more about your concerns?" would be a better way to explore the client’s feelings.
