Final answer:
The nurse must first consider the client's physiological and psychological needs when developing nurse-initiated interventions for abdominal pain.
Step-by-step explanation:
When developing appropriate nurse-initiated interventions for a client admitted to an acute care facility for abdominal pain, the nurse must first consider the client's physiological and psychological needs. This is because the nurse's interventions should be based on the specific needs of the client and their presenting symptoms.
While the institution's policies and procedures are important, they should be used as a guide rather than the sole basis for nursing interventions. The state's defined scope of nursing practice is also relevant, but it does not take precedence over the client's needs and the scientific rationale for the proposed nursing action.
For example, if a client with abdominal pain is experiencing severe nausea and vomiting, the nurse may consider administering antiemetic medications to address their physiological needs and alleviate discomfort.
