What is a thrill in cardiovascular assessment?
ANS: A thrill is a palpable vibration caused by turbulent blood flow. It may be felt
over areas of significant valvular stenosis or certain vascular abnormalities.
What is jugular venous pressure (JVP) used to assess?
ANS: JVP provides an indirect estimate of right atrial pressure and systemic
venous pressure. Elevated JVP can indicate right-sided heart failure, fluid
overload, or other conditions causing increased right-sided filling pressures.
A patient has bilateral neck-vein distention that increases when lying flat. What
should the nurse assess next?
ANS: Assess for other manifestations of elevated right-sided filling pressure,
including peripheral edema, hepatomegaly, weight gain, pulmonary symptoms, and
overall hemodynamic status.
What is hepatojugular reflux?
ANS: Hepatojugular reflux is a sustained increase in JVP when firm pressure is
applied over the abdomen. A positive response can support the presence of
elevated right-sided filling pressures.
What is peripheral edema in cardiovascular disease?
ANS: Peripheral edema is abnormal accumulation of interstitial fluid, commonly
resulting from increased venous hydrostatic pressure, sodium and water retention,
or reduced plasma oncotic pressure.
Why is unilateral leg edema different from bilateral dependent edema?
ANS: Unilateral edema raises concern for a localized process such as DVT,
venous obstruction, or inflammation, whereas bilateral dependent edema is more
commonly associated with systemic fluid retention or venous insufficiency.
What is chronic venous insufficiency?
ANS: Chronic venous insufficiency occurs when impaired venous return, often
,involving incompetent venous valves, causes venous hypertension and lower-
extremity swelling, aching, and skin changes.
What skin finding is commonly associated with chronic venous insufficiency?
ANS: Venous disease can cause hyperpigmentation, stasis dermatitis, edema, and,
in advanced cases, venous ulceration, commonly near the medial ankle.
How does an arterial ulcer typically differ from a venous ulcer?
ANS: Arterial ulcers are often painful, sharply demarcated, and located on distal
areas such as toes or feet, whereas venous ulcers commonly occur near the medial
ankle and are associated with edema and venous skin changes.
A patient with PAD reports foot pain that worsens when the leg is elevated and
improves when it is placed in a dependent position. Why?
ANS: Dependency can increase arterial perfusion through gravity, whereas
elevation may further reduce blood flow to an ischemic extremity.
What is critical limb ischemia?
ANS: Critical limb ischemia is severe peripheral arterial insufficiency associated
with chronic ischemic rest pain, nonhealing wounds, or gangrene and represents
advanced arterial disease requiring urgent evaluation.
What are the classic "6 Ps" associated with acute limb ischemia?
ANS: Pain, pallor, pulselessness, paresthesia, paralysis, and poikilothermia. Their
presence can indicate an acute vascular emergency.
A patient suddenly develops a cold, pale, painful leg with absent pulses. What
should be suspected?
ANS: Acute limb ischemia should be suspected. This is a vascular emergency
because prolonged loss of arterial perfusion can result in irreversible tissue injury.
What is a venous stasis ulcer?
ANS: A venous stasis ulcer is a chronic lower-extremity wound associated with
venous hypertension and impaired venous return, commonly occurring around the
medial ankle.
What is the purpose of compression therapy in chronic venous insufficiency?
ANS: Compression helps reduce venous pooling, improve venous return, decrease
edema, and support healing of appropriate venous ulcers when significant arterial
insufficiency has been excluded.
,Critical-thinking trap: Should compression stockings automatically be applied to
every patient with leg edema?
ANS: No. Significant arterial insufficiency must be considered because
compression can worsen perfusion in patients with severe PAD.
What is a venous thromboembolism (VTE)?
ANS: VTE is a collective term for thrombotic disease involving the venous
circulation, primarily deep vein thrombosis and pulmonary embolism.
What is Virchow's triad used to explain?
ANS: It describes the three major contributors to venous thrombosis: venous
stasis, endothelial injury, and hypercoagulability.
Why does prolonged immobility increase DVT risk?
ANS: Immobility reduces the skeletal-muscle pump that normally promotes
venous return, producing venous stasis and increasing thrombus formation risk.
What is the purpose of intermittent pneumatic compression devices?
ANS: They intermittently compress the lower extremities to promote venous
return and reduce venous stasis, particularly in patients at risk for VTE.
A postoperative patient refuses to ambulate because of discomfort. What
cardiovascular complication should the nurse consider preventing?
ANS: Prolonged immobility increases the risk of venous thromboembolism.
Appropriate pain control and early mobilization, when permitted, can reduce this
risk.
What is an embolus?
ANS: An embolus is material traveling through the bloodstream that can lodge in
a vessel and obstruct circulation. It may consist of thrombus, fat, air, or other
material.
What is an arterial embolism?
ANS: An arterial embolism occurs when an embolic material obstructs an artery,
abruptly reducing blood flow to the tissues supplied by that vessel.
A patient with atrial fibrillation suddenly develops a cold, painful foot with absent
pulses. What complication should be considered?
ANS: An arterial embolus originating from the heart should be considered because
, atrial fibrillation can promote intracardiac thrombus formation and systemic
embolization.
What is the purpose of anticoagulant therapy?
ANS: Anticoagulants reduce the formation or extension of thrombi by interfering
with the coagulation cascade. They do not directly dissolve an existing clot.
What is the key distinction between anticoagulants and thrombolytics?
ANS: Anticoagulants primarily prevent clot formation or extension, whereas
thrombolytic drugs actively promote breakdown of an existing thrombus in
selected emergency situations.
What is heparin-induced thrombocytopenia (HIT)?
ANS: HIT is an immune-mediated adverse reaction to heparin characterized by a
significant platelet decline and increased risk of thrombosis.
A patient receiving heparin has a substantial platelet decline and develops a new
thrombosis. What should be suspected?
ANS: HIT should be considered. Heparin exposure with thrombocytopenia and
new thrombosis requires urgent evaluation and appropriate management.
True or False: HIT is primarily a bleeding disorder because the platelet count
decreases. Explain.
ANS: False. HIT is primarily a prothrombotic disorder. Despite
thrombocytopenia, patients are at increased risk for potentially serious arterial and
venous thrombosis.
What is the International Normalized Ratio (INR) used to monitor?
ANS: INR standardizes the prothrombin time and is commonly used to monitor
the anticoagulant effect of warfarin.
Why is consistent vitamin K intake important for a patient taking warfarin?
ANS: Large fluctuations in dietary vitamin K can alter warfarin effectiveness.
Consistency helps maintain a more stable anticoagulant response.
A patient taking warfarin reports black, tarry stools. What should the nurse
recognize?
ANS: Melena may indicate gastrointestinal bleeding and requires prompt
evaluation, particularly in a patient receiving anticoagulant therapy.
