Essay Questions
1) Charlie has a blood test that shows a normal level of LDLs but an elevated level of HDLs in his
blood. Since his family has a history of cardiovascular disease, he wonders if he should modify his
lifestyle. What would you tell him?
Answer: Based just on the information given, Charlie would appear to be in good health, at least
relative to his diet and probable exercise. Problems are associated with elevated levels of LDLs,
which carry cholesterol to peripheral tissues and make it available for the formation of
