Question 25

HDL (high - density lipoprotein) cholesterol is known as "good" cholesterol. Lower levels of HDL are associated with a higher risk of arterial plaque deposits. A level of less than 45 mg/dL (for men, less than 50 for women) is considered low and increases the risk of plaque. Option a (8 - 20) is too low and not the typical range for HDL - related plaque risk. Option b (50 - 100) is a healthy range. Option d (greater than 100) is a very high, healthy range. So the correct answer is based on the knowledge of HDL cholesterol levels and their association with arterial plaque.

Urine specimens, if not tested within an hour, need to be refrigerated to prevent bacterial growth and changes in the chemical composition of the urine. Option a is incorrect as there's no need to dispose and replace unless the specimen is contaminated. Options b and c are incorrect as reheating is not the correct procedure for storing untested urine.

For a midstream clean - catch urine specimen, patients should cleanse the genital area from front to back in a single motion (for females, to prevent introducing bacteria from the anal area to the urethra; for males, it's also the proper direction). Option a (back to front) can introduce bacteria. Option c (side to side) and d (back and forth) are not the correct cleansing motions.

Answer:

c. less than 45
