A .73-year-old .retired .salesman .presents .to .the .Emergency .Department .complaining .of
chest .pain .that .started .about .2 .hours .ago. .Electrocardiogram, .cardiac .enzymes, .and
chest .x-ray .are .normal. .The .nurse .notes .that .his .blood .pressures .in .the .right .arm .are
significantly .lower .than .of .blood .pressures .in .his .left .arm. .Based .on .history .and .physical
examination, .which .of .the .following .will .most .likely .explain .his .signs .and .symptoms? . -
ANSWER- .a. .Dissecting .aortic .aneurysm
Rationale: .Patients .with .dissecting .aortic .aneurysms .typically .present .with .chest .pain,
many .times .described .as .a ."tearing" .type .pain. .They .are .usually .elderly, .and, .due .to .the
dissection .of .the .aorta, .asymmetric .pulses .in .blood .pressures .in .the .extremities .may .be
present. .Coarctation .of .the .aorta .can .also .cause .similar .symptoms; .however, .it .would .be
unlikely .due .to .the .patient's .age .as .this .is .a .congenital .defect. .MI, .PE, .and .pericarditis
are .also .common .causes .of .concerning .chest .pain; .however, .neither .typically .will .cause
asymmetric .blood .pressures .or .pulses .in .the .extremities.
A .19-year-old .carwash .attendant .sustained .a .laceration .to .the .ulnar .aspect .of .his .mid-
forearm .while .at .work .last .week. .He .did .not .have .it .evaluated .at .that .time .and .is .now
noticing .purulent .discharge .and .increasing .pain .from .the .wound .along .with .fever .and
chills. .Where .would .the .clinician .expect .to .find .the .first .signs .of .lymphadenopathy? . -
ANSWER- .a. .Epitrochlear .nodes
,Rationale: .The .epitrochlear .nodes .are .the .first .nodes .in .the .drainage .region .from .the
ulnar .surface .of .the .forearm .and .hand, .little .and .ring .fingers, .and .adjacent .surface .of .the
middle .finger. .Axillary .nodes, .infraclavicular .nodes, .and .cervical .chain .nodes .are .all
distal .to .this .area .and .may .show .evidence .of .lymphadenopathy .as .well; .however, .that
would .be .secondary .after .the .epitrochlear .nodes.
When .assessing .for .the .femoral .pulse, .where .should .the .clinician .begin .deeply
palpating? .- .ANSWER- .C. .Below .the .inguinal .ligament, .midway .between .the .anterior
superior .iliac .spine .and .symphysis .pubis
Rationale: .The .clinician .would .begin .deeply .palpating .below .the .inguinal .ligament,
midway .between .the .anterior .superior .iliac .spine .in .the .symphysis .pubis. .The .external
iliac .artery .transitions .into .the .femoral .artery .at .the .level .of .the .inguinal .ligament.
Therefore, .palpating .above .the .inguinal .ligament .would .be .assessing .the .external .iliac
artery. .The .femoral .artery .is .typically .located .midway .between .the .anterior .superior .iliac
spine .in .the .symphysis .pubis .in .most .patients.
The .clinician .is .palpating .pulses .in .the .foot .of .a .diabetic .patient .while .in .the .clinic. .A
strong .pulse .is .felt .located .on .the .dorsum .of .the .foot, .just .lateral .to .the .extensor .tendon
of .the .big .toe. .Which .artery .is .being .assessed? .- .ANSWER- .C. .Dorsalis .pedis
Rationale: .The .dorsalis .pedis .artery .is .usually .palpable .on .the .dorsum .of .the .foot .just
lateral .to .the .extensor .tendon .of .the .big .toe. .The .arterial .arch .of .the .foot .is .more .distal
and .runs .transversely .and .is .not .usually .palpable. .The .posterior .tibial .artery .is .found
,behind .the .medial .malleolus .of .the .ankle. .The .popliteal .and .femoral .pulses .are .found
more .proximally .at .the .knee .and .near .the .groin, .respectively.
A .68-year-old .retired .administrative .assistant .complains .of .a .3-month .history .of
recurring .pain .after .ambulating .that .radiates .from .her .back .in .the .upper .lumbar .region
into .both .buttocks, .bilateral .thighs, .and .mid-calf .regions. .Her .pain .is .typically .improved
by .sitting .or .by .leaning .forward. .The .origin .of .her .pain .is .likely .secondary .to .which .of .the
following? .- .ANSWER- .d. .Neurogenic .claudication
Rationale: .Neurogenic .claudication .can .mimic .PAD .by .causing .pain .related .to .walking;
however, .it .is .typically .relieved .simply .by .sitting .or .by .leaning .forward. .Many .patients
with .spinal .stenosis .of .the .lumbar .spine .have .pain .that .originates .in .the .spinal .region
and .radiates .into .the .areas .noted. .PAD .is .not .typically .relieved .just .by .sitting .alone .and
usually .will .take .some .time. .PAD .also .does .not .typically .improve .with .bending .over.
Acute .arterial .occlusion .does .not .cause .recurring .symptoms .and .is .not .usually .bilateral.
Abdominal .aortic .aneurysms .may .cause .similar .pain .as .well; .however, .they .typically .do
not .have .the .same .palliating .factors.
A .patient .that .has .a .known .history .of .cardiovascular .disease .including .a .myocardial
infarction .and .positive .ankle-brachial .index .indicating .peripheral .arterial .disease .in .his
left .leg .is .now .having .some .issues .with .erectile .dysfunction .(ED). .The .clinician .suspects
it .may .be .due .to .medications .or .further .vascular .disease. .He .does .not .complain .of .any
other .symptoms. .If .his .symptoms .are .related .to .vascular .disease, .where .would .the
lesion .likely .be .located? .- .ANSWER- .b. .Iliac .pudendal
, A .61-year-old .retired .librarian .was .recently .diagnosed .with .ovarian .cancer. .She .was
otherwise .healthy .until .her .recent .cancer .diagnosis. .She .has .not .been .feeling .well .lately
and .has .had .a .cough .and .some .mild .shortness .of .breath .for .the .past .couple .of .days.
She .now .presents .to .the .clinic .complaining .of .pain .and .swelling .in .her .right .groin .and
leg, .which .she .says .is .been .there .for .about .a .week .but .is .worsening. .On .physical
examination, .2+ .edema .of .the .right .leg .up .to .the .thigh; .1+ .femoral, .popliteal, .dorsalis
pedis, .and .posterior .tibial .pulses; .and .no .significant .erythema .are .noted. .What .is .the
chief .concern .with .this .patient? .- .ANSWER- .d. .Pulmonary .embolism .(PE)
Rationale: .Cancer .patients .are .at .high .risk .of .deep .venous .thrombosis .(DVT), .and, .with
the .presenting .symptoms .of .swelling .and .pain .in .her .groin, .along .with .recent .history .of
cough .and .shortness .of .breath, .this .patient's .presentation .is .suspicious .for .PE. .Patients
with .DVT .in .the .proximal .leg .veins .are .at .high .risk .of .thromboembolism. .Acute .arterial
occlusion .should .not .cause .significant .edema, .and .pulses .would .likely .be .absent. .The
constellation .of .symptoms .and .history .in .this .patient .also .does .not .suggest .an .acute
arterial .occlusion. .Superficial .thrombophlebitis .typically .only .causes .mild .local .swelling,
redness, .and .warmth .along .with .a .subcutaneous .cord. .Acute .lymphangitis .typically
presents .with .red .streaks .from .an .infection .passing .through .lymph .channels.
A .32-year-old .cabdriver .complains .of .pain .in .his .left .leg. .He .has .a .history .of .type .2
diabetes, .is .a .smoker, .and .recently .was .diagnosed .with .hypertension. .He .does .not
remember .injuring .his .leg; .however, .he .notes .that .there .is .a .small .wound .on .the .lateral
