Patients who have diabetes mellitus should have dilated eye exams at which of the following frequencies?
Biannually
Every 5 years
Annually
Every 10 years
The Correct Answer is C
A. Biannually: Biannual exams may not be frequent enough to monitor for diabetic retinopathy or other eye complications associated with diabetes. Annual exams are recommended.
B. Every 5 years: Waiting 5 years between exams is too long, as eye complications from diabetes can develop rapidly.
C. Annually: Annual dilated eye exams are recommended for patients with diabetes mellitus to monitor for diabetic retinopathy and other complications, allowing for early detection and treatment.
D. Every 10 years: A 10-year interval is far too long and could result in the progression of untreated eye disease, which could lead to blindness.

Correct Answer is B
Explanation
A. C-reactive protein (CRP): CRP is typically tested using a serum sample collected in a gold or red-top tube, not a light blue tube.
B. Partial thromboplastin time (PTT): PTT is a coagulation test that requires a light blue top tube containing sodium citrate, which acts as an anticoagulant. This tube is specifically used for coagulation studies.
C. Glucose: Glucose levels are commonly measured using a gray-top tube containing sodium fluoride to inhibit glycolysis, not a light blue tube.
D. Lactate: Lactate levels are typically measured using a gray-top tube or green-top tube, depending on the specific protocol, not a light blue tube.
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.
