BIOD 152 EXAM 4 QUESTIONS
1. Oxygenated blood is pumped from heart through the to the
rest of the body.:
A. Answer Left, systemic circuit
B. Right, pulmonary circuit
C. Left, pulmonary circuit
D. Right, systemic circuit
2. The sends deoxygenated blood to the lungs to be oxygenated
Answer: Right, pulmonary circuit
3. The "pacemaker of the heart" is in what location?:
A. Answer Right atrium
B. Left atrium
C. Left ventricle
D. Right ventricle
4. You are reviewing your patient's results from an EKG. The findings indicatea problem with
ventricular repolarization. Where should you look on the EKG to find this abnormal rhythm?:
A. Answer T-wave
B. QRS complex
C. P-wave
D. The electrical activity cannot be read on an EKG
5. Your patient's EKG results indicate difficulty with left and right atrial systole. What part
of the conduction system is not functioning properly?
: A.Atrioventricular node.
B. Answer SA node causes contraction of the left and right atria
C. Bundle of His
D. Purkinje fibers
6. Which statement is true concerning the cardiac cycle?:
A.The atrial contraction time is longer than the ventricle contraction time.
Answer B.The ventricular contraction time is longer than the atrial contraction time.
C. Systole refers to the relaxation of the heart chambers.
D. Diastole refers to the contraction of the heart chambers.
E. C & D are true
7. A patient is suspected to have peripheral edema due to heart failure.Whichside of the heart
would be in failure? Explain your answer.
Answer: The right side of theheart would be in failure. If the right side of the heart cannot
, pump blood into the heart efficiently, blood and fluid will back up into the veins, causing
swelling in bodytissues.
8. A patient has a diagnosis of left sided heart failure. Which of the following
signs/symptoms would they most likely present with?
Answer:
A. Shortness of breathat rest
B. Swollen ankles
C. All the above
9. A patient is admitted to the ER with a myocardial infarction. Whatsigns/symptoms could
they display?:
A. Shortness of breath
B. Angina pectoris
C. Heartburn
D. Pressure over the chest
E. Answer All the above
10. Your patient has a diagnosis of atherosclerosis. Is your patient at a higheror lower risk for
a thromboembolism? Explain your reasoning.
Answer: Higher risk. Thromboembolism is an embolus that becomes lodged in a vessel as it
travels. Atherosclerosis is an accumulation of soft masses of fatty materials, often cholesterol,
inside arteries. These deposits called plaque accumulate beneath the inner linings
of arteries. Plaque can cause a clot to form on the irregular arterial wall. If the clotbecomes
dislodged it can travel and clog a smaller artery in its path.
11. Which body system supplies cells with oxygen and nutrients and carriesaway waste?:
A. Nervous system
B. Respiratory system
C. Urinary System
D. Answer Circulatory System
12. The heart is contained in the
cavity.
Answer: pericardial
13. Which layer of heart anchors it to the diaphragm?:
A. Endocardium
B. Mediastinal
C. Myocardium
D. Answer Pericardium
14. What is the purpose of the mitral valve?
Answer: The mitral valve controls the flow ofblood from the left atrium into the left ventricle.
