BIOD 152 MODULE 4 EXAM
1. The ....... sends deoxygenated blood to the lungs to be oxygensted
Answer: Right,pulmonary circuit
2. Oxygenated blood is pumped from the heart through the to
the restof the body:
A. Answer Left, systemic circuit
B. Right, pulmonary circuit
C. Left, pulmonary circuit
D. Right, systemic circuit
3. the pacemaker of the heart is the:
Answer: SA node
4. you are reviewing your patients results from an EKG. the findings indicatea problem with
ventricular depolarization. where should you look on the EKGto find the abnormal rythm?
Answer: QRS complex
5. Your patient's EKG results indicate difficulty with left and right ventricularsystole. What
part of the conduction system is not functioning properly?
Answer: - purkinje fibers
6. Which statement is true concerning the cardiac cycle
Answer: A and B, the dub sound is heard when the semilunar valves close and the lub sound
is heard whenthe atrioventricular valves close/
OR
the ventricular contraction time is longer than the atrial contraction time
The Ventricular cleared of contraction time is longer than actual contraction time
7. a patient is suspected to have pulmonary edema due to congestive heartfailure. Which
side of the heart would be in failure?
Answer: the left side of the heart would be in failure. if the left side of the heart cannot pump
blood out to the body tissues efficiently, blood and fluid will back up into the lungs
left sided heart failure because pulmonary edema occurs by fluid backup into thelungs when
the left sided heart is not able to pump blood property to the body
, 8. a patient has a diagnosis of right sided CHF. which of the following signs/symptoms
would they most likely present with?
Answer: swollen ankles
9. a patient is admitted to the ER with a myocardial infarction. what signssymptoms would
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 dx of atherosclerosis. would you expect them to alsohave
hypertension? why or why not
Answer: Yes. 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. as plaque continuesto build up it
tends to protrude into the vessel, interfering with normal blood flow
Yes because atherosclerosis occurs when the plaque buildup in the arteries and causes
narrowing of the arteries which can lead to increased pressure within thevessel(hypertension)
11. your patient is admitted to the hospital for coronary artery bypass. explainwhat is going to
happen in this surgery for your patience
Answer: A surgeon will take a section of the vessel for one area, then attach one end at the
aorta and the otherend to a coronary artery past the point of obstruction resuming the blood
flow.
12. the heart is contained in the cavity:
A. Answer Pericardial
B. Pleural
C. Septal
D. Rectoperineal
13. the aortic arch turns to become the ?:
A. Superior vena cava
B. Pulmonary trunk
C. Ascending aorta
D. Answer Descending aorta
14. what is the name of the artery in the figure below (in blue also indicatedby the arrow?
Answer: anterior communicating artery
