Correct Answer is D
Explanation
A. "Controlling my blood pressure will decrease my risk of having a heart attack to some degree." This statement is accurate. Controlling blood pressure reduces the risk of developing ACS.
B. "Because I'm over 80, even a 20 mm Hg drop in my blood pressure can reduce my risk." Research indicates that even modest reductions in blood pressure can significantly lower the risk of cardiovascular events, especially in older adults.
C. "High blood pressure will increase my body's need for oxygen and increase my heart's workload." High blood pressure increases myocardial oxygen demand and can lead to ischemia, which is a precursor to ACS.
D. "My high blood pressure has no relationship to the severity of heart disease or its outcomes." This statement is false. High blood pressure is a major risk factor for heart disease, including ACS, and it directly affects the severity and outcomes of heart disease.
Correct Answer is B
Explanation
A. Dark colored urine: Dark urine can be a sign of bilirubin buildup in the body due to liver dysfunction, commonly seen in cirrhosis.
B. Dark colored stool: This is not typically associated with cirrhosis. Dark stools can indicate gastrointestinal bleeding, but in cirrhosis, stools are more likely to be pale or clay-colored due to a lack of bile.
C. Jaundice: Jaundice occurs due to the liver's inability to process bilirubin, leading to yellowing of the skin and eyes.
D. Pruritus: Pruritus, or itching, is common in cirrhosis due to bile salt deposition in the skin.
E. Ascites: Ascites, the accumulation of fluid in the abdomen, is a common complication of cirrhosis due to portal hypertension and low albumin levels.
