Answer to Question 1

B
A decreased incidence of coronary heart disease is associated with high HDL cholesterol, low LDL cholesterol, and low triglyceride levels (response B). Response A is incorrect in all parameters. Although total cholesterol levels are valuable tools, they should be combined with a measure of HDL and LDL cholesterol. Older people may have a total cholesterol level within normal range but have low HDL and elevated LDL levels and be at increased risk for coronary heart disease (response C). Triglyceride levels should be low to guard against coronary heart disease (response D).

Answer to Question 2

B
Patients receiving digoxin are at high risk from arrhythmias secondary to low potassium levels. Res-ponses A, C, and D are normal values. Response B is low and would be a concern for the nurse.
