Answer to Question 1

Ans: B
Feedback:
Dysrhythmias range from minor, clinically insignificant abnormalities to life-threatening conditions. Dysrhythmias may be caused by damage to the heart muscle or conduction system, diminished coronary blood flow, decreased blood oxygen levels, medications, alterations in serum electrolytes, stress, or overstretching of the heart muscle.

Answer to Question 2

Ans: C
Feedback:
Exercise protects the cardiovascular system and promotes weight reduction by raising the good HDL cholesterol and reducing triglycerides. Sodium is traditionally restricted in clients with cardiovascular health concerns. Excessive sodium intake will result in fluid retention. Exercise acts to reduce blood glucose.
