Final answer:
The etiology of the problem in a nursing diagnosis statement suggests the nursing interventions to be included in a care plan, as it informs the development of interventions targeted at the underlying causes of the health issue.
Step-by-step explanation:
In the context of a nursing diagnosis statement, the part that suggests the nursing interventions to be included in the plan of care is the etiology of the problem. This component, also known as the related factor, is essential in determining the cause or contributing factors of the health problem and thus informs the development of appropriate nursing interventions.
The problem statement itself identifies what is wrong with the patient, while the defining characteristics support the diagnosis with observable evidence. Outcomes criteria are the goals that reflect the desired patient outcomes and are not specifically suggesting interventions.
Identifying a problem's etiology helps in establishing criteria and constraints for developing a nursing care plan, ensuring that the interventions are targeted at the underlying causes of the patient's problem. Without this focus, the nursing care might not be as effective in addressing the patient's needs.
