A patient has been reading on the Internet that light to moderate intake of alcohol is cardiopro-tective
When the patient asks the nurse what this means, the nurse should respond that the heart is pro-tected by which of the following mechanisms? (select all that apply)
a. Increased levels of high-density lipopro-tein cholesterol
b. Prevention of clot formation
c. Reduction in platelet aggregation
d. Decrease in blood pressure
e. Increased collateral circulation
f. Decreased folate absorption
ANS: A, B, C, D
The suggested mechanisms for cardioprotection by low to moderate alcohol intake include in-creased levels of high-density lipoprotein cholesterol (HDL-c), prevention of clot formation, re-duction in platelet aggregation, and decrease in blood pressure. Increased collateral circulation is not a benefit of alcohol. Alcohol consumption can decrease folate absorption, which can lead to a nutritional deficient.
