Final answer:
Nursing diagnoses focus on the patient's response to health problems, while medical diagnoses focus on the identification of diseases or conditions.
Step-by-step explanation:
The primary difference between nursing diagnoses and medical diagnoses is that nursing diagnoses focus on the patient's response to health problems, while medical diagnoses focus on the identification of diseases or conditions. Nursing diagnoses take into account the physical, emotional, sociocultural, and spiritual factors that influence a patient's response to a health issue. On the other hand, medical diagnoses are based on objective data such as laboratory tests, imaging studies, and physical examinations.
