Answer:
If a patient is unconscious and requires immediate attention, the medical records data that would best help a physician determine what to prescribe is the patient's allergies (option D).
Explanation:
An unconscious patient cannot provide data to the attending physician. One of the ways to know what medication can be prescribed when treating him is to review his medical history or medical records.
In the medical records there are data related to the health and illness of a person, one of them is the history of allergies that a patient presents. Knowing what medication can cause an allergy, and make health worse, is important in order to administer medication safely.
The other options are not valid because:
A. The history of health exams does not provide data to decide which medications to prescribe.
B. The patient's family contacts may be useful, but he needs to be attended to immediately without loss of time.
C. The patient's family history does not necessarily indicate what medication he is allergic to or what can be prescribed.
