Chapter 42: Introduction to the Cardiovascular System
Questions With Complete Solutions
A heart transplantation patient has no nerve connections to the
transplanted heart. In such an individual, one would expect to
find:
A) A slower than normal resting heart rate
B) Atria that contract at a different rate than ventricles
C) An increase in heart rate during emotional stress
D) Inability to exercise because there is no way to increase heart
rate Correct Answers C
A nurse is caring for a pt whose BP is 148/89. This will affect
the pt's cardiac oxygen consumption by:
A) Increasing afterload
B) Increasing heart rate
C) Inhibiting conduction
D) Increasing preload Correct Answers A
A nurse is describing an action of the heart, likening it to that of
stretching a rubber band. What is the nurse describing?
A) Automaticity
B) Conductivity
C) Starling's Law of the Heart
D) Capacitance system Correct Answers C
A pt is believed to be experiencing an increase in the release of
natriuretic peptides. What assessment finding would best
confirm this?
A) The pt's BP is trending downward
B) The pt has a "bounding" brachial pulse
, C) Adventitious lung sound is audible on auscultation
D) The pt has developed a sinus arrhythmia Correct Answers
A
A pt is brought to the ER with a suspected myocardial
infarction. The pt is very upset because he had just had an ECG
in his doctor's office and it was fine. The explanation of this
common phenomenon would include the fact that:
A) The ECG only reflects changes in cardiac output
B) The ECG is not a very accurate test
C) The ECG only measure the flow of electrical current through
the heart
D) The ECG is not related to the heart problems Correct
Answers C
A pt's ECG reveals the presence of atrial fibrillation. The nurse
should recognize what implication of this?
A) Cardiopulmonary resuscitation will likely be necessary
B) Several sites apart from the SA node are producing electrical
impulses
C) The clientonary resuscitation will likely be necessary
D) The pt has a heart block Correct Answers B
An intensive care pt's ECG indicates ventricular fibrillation.
What is the nurse's best action?
A) Administer diuretics as prescribed to reduce afterload
B) Assess the pt's BP
C) Initiate cardiopulmonary resuscitation
D) Facilitate a referral to cardiology Correct Answers C
