Which insulins should never be mixed?
- A.
Rapid-acting insulins
- B.
Short-acting insulins
- C.
Intermediate-acting insulins
- D.
Long-acting insulins
Correct Answer
D. Long-acting insulinsExplanation
Long-acting insulins should never be mixed with any other type of insulin. This is because long-acting insulins are designed to provide a steady release of insulin over an extended period of time, while other types of insulin have different durations of action. Mixing long-acting insulins with other insulins can alter their pharmacokinetics and lead to unpredictable effects on blood sugar control. Therefore, it is important to administer long-acting insulins separately and not mix them with any other type of insulin.Rate this question:

D. Humulin
E. NovolinExplanation
Regular (R), Humulin, and Novolin are short-acting insulins. Lantus and Lente (L) are long-acting insulins. Short-acting insulins have a rapid onset of action and a shorter duration of action, typically lasting for about 2-4 hours. They are used to control blood sugar levels after meals or to correct high blood sugar levels. Long-acting insulins, on the other hand, have a slower onset of action and a longer duration of action, providing a steady release of insulin over a longer period of time to maintain basal insulin levels throughout the day.Rate this question:
