Final answer:
In the scenario described, you have established a working diagnosis of asthma for the 5-year-old girl. This is based on her symptoms of wheezing when exposed to cats and a positive family history of asthma.
Step-by-step explanation:
In the given scenario, you have accomplished option C, you have established a working diagnosis. This term refers to a preliminary diagnosis made by a doctor based on the observed symptoms and patient history while waiting for more conclusive test results. In this case, the 5-year old girl's wheezing triggered by exposure to cats, along with the positive family history for asthma, strongly suggests she may have asthma.
A working diagnosis helps medical professionals manage a patient's symptoms and treatment without being 100% certain of the full diagnosis. It does not represent a tested and verified hypothesis which could be option A. The working diagnosis is also not a developed plan (option B) which would include a comprehensive approach to treating and managing the patient's condition. Finally, although a hypothesis has been made that the girl might have asthma, the observations in this instance extend beyond forming a basic hypothesis (option D) to forming a working diagnosis based on the available evidence.
