Which of the following tests can be run using a light blue collection tube?
C-reactive protein (CRP)
Partial thromboplastin time (PTT)
Glucose
Lactate
The Correct Answer is B
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 A
Explanation
A. Pull the lower eyelid down. Pulling the lower eyelid down creates a pocket for the drops, making it easier to administer them without contacting the eye’s surface directly.
B. Have the patient open their eye using both hands: Using both hands to open the eye may be uncomfortable and unnecessary; the assistant should guide the patient gently.
C. Use a retractor on the eye before administering the drops: Retractors are not typically used for eye drop administration; this can cause discomfort and is not standard practice.
D. Hold the dropper 1 inch away from the surface of the eye: The dropper should be held close enough to the eye to avoid contaminating the eye surface or the dropper, but not so close as to touch the eye.
