Correct Answer is A
Explanation
A. Ensure the otoscope is in the room. Ensuring that the otoscope and other necessary equipment are in the room is an important step in preparing the room for a physical examination.
B. Replace the half-full sharps containers. Sharps containers should be replaced when they are three-quarters full, not necessarily when they are half-full. This action, while important, is not specific to preparing for a general physical examination.
C. Obtain preauthorization from insurance. Preauthorization is an administrative task that is not directly related to preparing an examination room.
D. Sterilize counter surfaces in the room. Cleaning and disinfecting counter surfaces is important for infection control but typically would have been done after the last patient. This action is less directly related to preparing for a general physical exam compared to ensuring the necessary equipment is present.
Correct Answer is C
Explanation
A. Gluteus maximus: The gluteus maximus is not a commonly used site for body fat measurement.
B. Biceps: The biceps are not typically used for body fat measurement. Measurements are usually taken at sites with more subcutaneous fat.
C. Infrailiac region: The infrailiac region, located just above the iliac crest (hip bone), is a common site for measuring body fat, along with other areas such as the triceps and subscapular region.
D. Triceps: While the triceps can be used for body fat measurement, the infrailiac region is another standard site used for accuracy in some methods.
