HSS 3305 MODULE 5 PRACTICE EXAM
QUESTIONS WITH VERIFIED ANSWERS
What is the primary function of the right side of the heart?
To receive oxygen-poor blood from the body and pump it to the lungs.
What is the primary function of the left side of the heart?
To receive oxygenated blood from the lungs and pump it throughout the body.
What is the average weight of a healthy heart?
250-350 grams.
What are the two main types of circuits in the cardiovascular system?
Pulmonary circuit and systemic circuit.
What is the pericardium?
A protective membrane surrounding the heart.
What are the two layers of the serous pericardium?
Outer parietal layer and inner visceral layer (epicardium).
What is pericarditis?
Inflammation of the pericardium, often causing chest pain.
What is pericardial effusion?
The accumulation of blood or fluid in the pericardium.
What is cardiac tamponade?
A condition where fluid in the pericardium puts pressure on the heart, preventing it from fully
expanding.
What are the three clinical signs of Beck's triad associated with cardiac tamponade?
Low blood pressure, muffled heart sounds, and jugular vein distension.
What is pericardiocentesis?
A procedure to aspirate fluid from the pericardial cavity in patients with cardiac tamponade.
What is the size of the heart in relation to the human fist?
About the size of a closed fist.
Where is the heart located in the thoracic cavity?
, In the mediastinum, medially between the lungs.
What is the apex of the heart?
The pointed end of the heart that lies to the left of the midline.
What is the base of the heart?
The broad posterior surface of the heart.
What is the role of pericardial fluid?
To prevent friction between the parietal and visceral pericardium.
What can cause pericarditis?
Infections (e.g., viruses or bacteria), post-infarct conditions, or Dressler's syndrome.
What is the significance of the left ventricular free-wall rupture case study?
It illustrates the critical nature of cardiac complications and the need for immediate intervention.
What happens during cardiac tamponade?
Excess pressure from fluid prevents the heart from pumping effectively, leading to hypotension.
What anatomical landmarks are used to locate the heart?
Costal cartilages of the ribs and the midclavicular line.
What are the two main types of heart chambers?
Atria and ventricles.
What is the function of the atria?
To receive blood from the pulmonary and systemic circuits.
What is the function of the ventricles?
To pump blood out of the heart.
What is the role of researchers in the context of heart transplants?
To develop synthetic organs from patients' own cells to reduce rejection risks.
What is the main risk associated with heart transplants?
The body's rejection of the new heart due to immune reactions.
What is the purpose of creating donor hearts from a patient's own cells?
To eliminate the chance of rejection.
What is the significance of the heart's location in the thorax?
