Final answer:
To determine the etiology of an illness using the explanatory model, a nurse should ask the patient what they call their problem and how the illness works inside their body.
Step-by-step explanation:
When using the explanatory model to determine the etiology of an illness, a nurse should ask the following questions:
- What do you call your problem? This question helps the nurse understand the patient's perception of the illness and its name.
- How does this illness work inside your body? This question helps the nurse understand the patient's understanding of the disease process and its mechanisms.
These questions allow the nurse to gain insight into the patient's beliefs, knowledge, and explanatory model of the illness, which can guide treatment decisions and help develop effective treatments.
