Which of the following statements concerning the flow of blood to and through the right side of the heart is correct?
A) Blood reaches the right atrium from the aorta, is pumped through the mitral valve into the right ventricle, and is then pumped through the pulmonary veins to the lungs.
B) Poorly oxygenated blood reaches the right ventricle from the venae cavae, is pumped through the pulmonic valve into the pulmonary artery, and then enters the right atrium and is pumped into the lungs.
C) Oxygenated blood reaches the right atrium from the pulmonary veins, is pumped through the tricuspid valve into the right ventricle, and is then pumped into the aorta and throughout the body.
D) Poorly oxygenated blood reaches the right atrium from the venae cavae, is pumped through the tricuspid valve into the right ventricle, and is then pumped through the pulmonic valve and on to the lungs through the pulmonary arteries.

After jogging with your friend for about 30 minutes, she stops and asks why your heart rate increases and your heart feels like it is pumping harder after you exercise for a while. Based on your understanding of the cardiovascular system, your best response would be which of the following statements?
A) “You’re out of shape. Those things wouldn’t happen if you exercised more.”
B) “Exercise makes your body need more nutrients and oxygen. Your heart pumps harder and faster to deliver more blood containing those things to your muscles.”
C) “When you exercise, your blood pressure increases, so your heart has to work harder to overcome the higher blood pressure.”
D) “Exercise pushes more blood into your heart, so your heart has to work harder and faster to pump the blood out so you don’t go into heart failure.”

Your neighbor tells you that he is concerned about his 70-year-old wife. She is at home recovering from a heart attack that occurred about 3 weeks ago. He explains that over the last few days, her ankles and lower legs have been gradually swelling and are painful to touch. Today, she seems to be a little short of breath. You recommend that your neighbor seek immediate medical attention because these findings are suggestive of:
A) congestive heart failure.
B) tension pneumothorax.
C) an acute myocardial infarction.
D) pericarditis.

Which of the following statements indicates that the speaker has an understanding of chest pain and acute myocardial infarction?
A) “If the chest pain started during activity, it is most likely cardiac in origin. If the pain started while the patient was at rest, it is most likely not cardiac in origin.”
B) “If the patient’s chest pain does not go away with nitroglycerin, you can assume that the medication has expired and is no longer effective.”
C) “If the patient experiences chest pain that radiates into the left arm, it is most likely a heart attack. If the pain radiates anywhere else, it is most likely not cardiac in origin.”
D) “Some patients experiencing acute myocardial infarction do not have actual chest pain. Instead, they may experience a sensation of ‘severe heartburn.’ ”
