Emergency medical technicians respond to a call to find an 80-year-old man
who is showing S/S of severe shock. Which of the following phenomena is
most likely taking place? - ANS ✅The man's alpha & beta-adrenergic receptors
have been activated, resulting in vasoconstriction and increased HR
Central response to all types of shock
A 3-year-old child with right-sided heart failure has been admitted for
worsening of his condition. Which of the following assessment would be
considered one the earliest signs of venous congestion in this toddler? - ANS
✅Enlargement of the liver
With RV function impaired, systemic venous congestion develops
Which of the following changes associated with aging contributes to heart
failure development in older adults? - ANS ✅Elevated diastolic BP
Increased vascular stiffness
Knowing the high incidence and prevalence of heart failure among the
elderly, the manager of a long term care home has organized a workshop on
the identification of early signs and symptoms of heart failure. Which of the
following teaching points is most accurate? - ANS ✅Displays of aggression,
confusion and restlessness when the resident has no history of such behavior can
be a sign of heart failure

Cognitive changes can often accompany heart failure in the elderly
As part of pre-surgical teaching for patients who are about to undergo a
coronary artery bypass graft, a nurse is performing an education session
with a group of surgical candidates. Which of the following teaching points
best conveys an aspect of human circulatory system? - ANS ✅The blood
pressure varies widely between arteries and veins and between pulmonary and
systemic circulation
In which of the following situations would blood most likely rapidly
relocate from central circulation to the lower extremities? - ANS ✅A client
is helped out of bed and stands up
Which of the following statements most accurately captures a principle of
blood flow? - ANS ✅With constant pressure, a small increase in vessel radius
results in an exponential increase in blood flow
Doubling the radius of a vessel is associated with a fourth-power increase in
flow, provided that pressure remains constant
A 72-year-old female has been told by her physician that she has a new
heart murmur that requires her to go visit a cardiologist. Upon
examination, the cardiologist informs the patient that she has aortic
stenosis. After the cardiologist has left the room, the patient asks, "What
caused this to happen now?" The clinic nurse responds, - ANS ✅"Heart
murmurs result from tumultuous flow through a diseased heart valve that is too
narrow and stiff. This flow causes a vibration called a murmur."
Heart murmur results from turbulent flow through a diseased heart valve
that may be too narrow, too stiff, or too floppy.
During an automobile accident where the patient is bleeding heavily, which
vascular component is the most distensible and can store large quantities of

blood that can be returned to the circulation at this time of need? - ANS
✅Veins
Compliance refers to the total quantity of blood that can be stored in a given
portion of the circulation for each mmHg rise in pressure
An 81-year-old female client of a long-term care facility has a history of
congestive heart failure. The nurse practitioner caring for the client has
positioned her sitting up at an angle in bed and is observing her jugular
venous distention. Why is jugular venous distention a useful indicator for
assessment of the client's condition? - ANS ✅Blood back up into the jugular
vein because there are no valves at the point of entry into the heart
As part of their orientation to a cardiac care unit, a group of recent nursing
graduates is receiving a refresher in cardiac physiology from the unit
educator. Which of the following teaching points best captures a component
of cardiac function? - ANS ✅The diastolic phase is characterized by relaxation
of the ventricles and their filling with blood
A patient is experiencing impaired circulation secondary to increased
systemic arterial pressure. Which of the following statements is the most
relevant phenomenon? - ANS ✅High afterload because of back pressure
against the left ventricle
increased pressure in the aorta and other arteries constitutes a greater
amount of afterload work
In the ICU, the nurse hears an emergency cardiac monitor go off. The nurse
looks at the telemetry and notices the patient has gone into ventricular
tachycardia. The nurse will likely assess for signs/symptoms of: - ANS
✅decreasing cardiac output due to less ventricular filling time
heart does not have the time to fill adequately

A nurse is using a stethoscope and blood pressure cuff to manually measure
a client's blood pressure. The nurse knows that which of the following facts
related to blood flow underlies the ability to hear blood pressure by
auscultation (listening)? - ANS ✅Pressure pulsation that exceeds the velocity
of blood flow is audible and coincides with systolic BP.
The pressure pulsations that accompany intermittent blood ejection from
the ventricles cause sounds that are audible when measuring blood
pressure and palpable at pulse sites
A patient arrived at the emergency department 2 days after the
development of "chest pressure" and "tightness" was treated with antacids
thinking it was indigestion. Hi enzymes show a massive MI. Following
angioplasty, the patient asks why so much muscle was damaged if only one
vessel was blocked, the left circumflex. The nurse responds, - ANS ✅"If a
major artery like the circumflex is occluded, the smaller vessels supplied by that
vessel cannot restore blood flow."
Hyperaemia cannot occur when the arteries that supply the capillary beds
are narrowed.
When explaining to a patient why he only had minimal muscle damaged
following 99% occlusion of the left anterior descending artery, the nurse
will explain this is primarily due to - ANS ✅development of collateral
circulation that builds channel between some of the smaller arteries usually
when the flow is decreased gradually
Which of the following individuals is most likely to be experiencing
vasodilation? - ANS ✅A 51-year-old man with a history of hypertension who is
taking a medication that blocks the effect of the renin-angiotensin-aldosterone
system
Angiotensin is a potent vasoconstrictor, and meds that block this induce
vasodilation
