  a. Experiences chest pain after eating a heavy meal
  b. Experiences adequate oxygen saturation during exercise
  c. Experiences crushing chest pain for more than 20 minutes
  d. Experiences tingling in the left arm that lasts throughout the morning

Question 2

  b. Increased heart rate
  c. Decreased afterload
  d. Decreased tissue perfusion

Answer to Question 1

ANS: A
Angina pectoris is chest pain that results from limited oxygen supply. Often pain is precipitated by activities such as exercise, stress, and eating a heavy meal and lasts 3 to 5 minutes. Symptoms of angina pectoris are relieved by rest and/or nitroglycerin. Adequate oxygen saturation occurs with rest; inadequate oxygen saturation occurs during exercise. Pain lasting longer than 20 minutes or arm tingling that persists could be a sign of myocardial infarction.

Answer to Question 2

ANS: A
Preload refers to the amount of blood in the left ventricle at the end of diastole; an increase in circulating volume would increase the preload of the heart. Afterload refers to resistance; increased pressure would lead to increased resistance, and afterload would increase. A decrease in tissue perfusion would be seen with hypovolemia. A decrease in fluid volume would cause an increase in heart rate as the body is attempting to increase cardiac output.
