You may be talking about change from rapid-acting insulin to intermediate-acting insulin. Rapid acting insulin, as it implies, has onset of 10 to 30 minutes and peaks in 3 hours. Meanwhile, the intermediate-acting insulin takes 1 hour and 30 minutes to 4 hours to take effect, and it peaks in 4 to 12 hours. If changing from rapid-acting to intermediate-acting, there is a big space where there might be no insulin in the body to control blood sugar levels. As a nurse, you should carefully monitor blood glucose levels every 30 minutes and watch out for symptoms of hypeglycemia.
The correct answer is co-adaptation.
Co-adaptation in biology refers to the procedure by which two or more species, phenotypic traits or genes go through adaptation as a group or pair. This takes place when two or more associating features go through natural selection together in response to the similar selective pressure or when selective pressures change one feature and simultaneously changes the interactive feature. These associating features are only beneficial when together, in certain cases resulting in increased interdependence.
