◉ When a nursing student wants to know where the primary
cardiovascular control center is located, what is the nurse's best
response? In the:
A. Cerebral cortex

D. Cervical spinal cord. Answer: Medulla
,◉ A nurse is discussing the pressure generated at the end of
diastole. Which term is the nurse describing?
A. Preload
B. Afterload
C. Systemic vascular resistance
D. Total peripheral resistance. Answer: Preload
◉ A cardiologist is teaching about myocardial cells. Which
information should the cardiologist include? _____ are thickened
areas of the sarcolemma of myocardial cells that enable electrical
impulses to travel in a continuous cell-to-cell fashion.
A. Myosins
B. Intercalated disks
C. Troponin Ts
D. I bands. Answer: Intercalated disks
◉ A cardiologist is discussing valves with the staff. Which
information should the cardiologist include? _____ are the anchors of
the atrioventricular valves.
A. Chordae tendineae cordis
,B. Great vessels
C. Coronary ostia

◉ When a student nurse asks the nurse how the cardiac electrical
impulse normally begins, what is the most correct response? The
cardiac electrical impulse normally begins spontaneously in the
sinoatrial (SA) node because it:
A. Has a superior location in the right atrium
B. Is the only area of the heart capable of spontaneous
depolarization
C. Has rich sympathetic innervation via the vagus nerve
D. Depolarizes more rapidly than other automatic cells of the heart.
Answer: Depolarizes more rapidly than other automatic cells of the
heart
◉ The nurse is reviewing a normal electrocardiogram. The nurse
assesses
the PR interval because it represents:
A. Atrial depolarization
B. Ventricular depolarization
C. Onset of atrial activation to onset of ventricular activity
, D. "Electrical systole" of the ventricles. Answer: Onset of atrial
activation to onset of ventricular activity
◉ A 75-year-old male has severe chest pain and dials 911. Lab tests
at the hospital reveal elevated levels of cardiac troponins I and T.
Based upon the lab findings, the nurse suspects which of the
following has occurred?
A. Orthostatic hypotension
B. Varicose veins
C. Myocardial infarction (MI)
D. Raynaud disease. Answer: Myocardial infarction (MI)
◉ A nurse is teaching staff about endocarditis. Which information
should the nurse include? Inflammatory cells have difficulty limiting
the colonization of microorganisms in infective endocarditis because
the:
A. Colonies overwhelm the phagocytes.
B. Microorganisms are resistant.
C. Valves are avascular.
D. Microorganisms are sequestered in a fibrin clot.. Answer:
Microorganisms are sequestered in a fibrin clot
