Nursing Care for NPH Insulin
Let's evaluate each option carefully by considering the specific properties of NPH insulin.
The first option suggests discarding the NPH solution if it appears cloudy.
- Discard if cloudy
Actually, NPH is an intermediate acting insulin suspension, which means it is naturally cloudy. It should not be discarded for this reason.
The second option suggests shaking the insulin vigorously before loading the syringe.
- Shake vigorously
This is incorrect. Vigorously shaking insulin can create bubbles and damage the protein molecules. Instead, we should gently roll the vial between the palms.
