b. Lack of knowledge
When considering priority setting of problems, second-level priority problems typically include aspects related to lack of knowledge or education.
Second-level priority problems are those that do not pose an immediate threat to life or risk of serious harm, but they still require attention and intervention within a reasonable timeframe. These problems often involve knowledge deficits, potential complications, or factors that may contribute to further health issues if left unaddressed.
Lack of knowledge is a common example of a second-level priority problem. Patients or individuals who lack knowledge or understanding about their health condition, treatment plan, or self-care management may be at risk of complications or suboptimal outcomes if they are not provided with appropriate education and guidance.
Other examples of second-level priority problems related to lack of knowledge may include:

1. Patient needs education on medication administration or side effects.
2. New parent requires guidance on infant care and feeding.
3. Individual with a chronic condition needs education on lifestyle modifications or disease management.
