A.
scalp .hematoma.
.B.
subdural .hematoma.
.C.
epidural .hematoma.
.D.
intracerebral .hematoma. .- .correct .answer.C. .epidural .hematoma.
Linear .fractures .of .the .temporal .bone .frequently .disrupt .the .middle .meningeal .artery .and
.cause .epidural .hematoma. .Patients .with .an .epidural .hematoma .classically .present .with .a
.short .period .of .unconsciousness .followed .by .a .lucid .interval .and .then .rapid .deterioration.
.An .epidural .hematoma .is .usually .caused .by .arterial .bleeding.
A .patient .is .admitted .to .the .ICU .after .sustaining .a .concussion .and .blunt .abdominal
.trauma .to .the .right .upper .quadrant .in .a .domestic .dispute. .The .patient's .vital .signs .are .BP
.145/86 .mm .Hg, .pulse .86 .beats/min, .respiration .15 .breaths/min, .and .temperature .98.8° .F.
.The .nurse .is .monitoring .the .patient's .bowel .sounds, .abdominal .tenderness, .and
.abdominal .girth .frequently. .Which .of .the .following .laboratory .parameters .is .especially
.important .for .the .nurse .to .closely .monitor .for .bleeding .in .this .patient?
A.
Platelet .count
,.B.
Protime
.C.
Hematocrit
.D.
Mean .corpuscular .volume .- .correct .answer.C. .Hematocrit
Common .injuries .resulting .from .blunt .abdominal .trauma .can .include .injury .to .the .liver,
.spleen, .mesenteric .vessels, .pancreas, .or .kidneys. .In .a .nonoperative .approach .to .blunt
.abdominal .trauma, .observation .and .monitoring .include .serial .hematocrits .to .evaluate .for
.intra-abdominal .bleeding. .The .platelet .count .does .not .fluctuate .unless .there .is .a .disease
.process .(e.g. .cirrhosis, .leukemia) .or .significant .blood .loss. .Protime .is .a .monitor .of
.coagulation .status .and .can .be .prolonged .without .active .bleeding. .Mean .corpuscular
.volume .measures .the .average .volume .or .size .of .a .single .RBC .and .is .used .in .classifying
.anemias.
Which .of .the .following .is .associated .with .chest .pain, .confusion, .and .petechiae?
A.
Dissecting .aneurysm
.B.
Fat .embolism
.C.
Pneumothorax
.D.
Myocardial .infarction .- .correct .answer.B. .Fat .embolism
Chest .pain, .confusion, .and .petechiae .are .suggestive .of .a .fat .embolism, .especially .within
.the .first .48 .to .72 .hours .after .a .long-bone .fracture.
The .clincher .is .the .petechiae. .None .of .the .other .choices .would .cause .petechiae.
Which .type .of .shock .is .most .likely .to .be .iatrogenic?
A.
Hypovolemic
.B.
Cardiogenic
.C.
Septic
.D.
Neurogenic .- .correct .answer.C. .Septic
Iatrogenic .means .caused .by .treatment .or .diagnostic .procedures .or .medically .induced.
.Septic .shock .is .the .type .of .shock .most .likely .to .be .iatrogenic. .Significant .contributors
.include .immunosuppressive .medications .and .therapies .and .invasive .procedures.
, A .patient .had .a .craniotomy .2 .days .ago .for .removal .of .a .tumor. .He .is .awake .and .talking .to
.the .nurse .and .demonstrates .no .neurologic .deficit. .Blood .pressure .is .110/80 .mm .Hg,
.pulse .is .92 .beats/min, .and .respiratory .rate .is .22 .breaths/min. .Urine .outputs .have .been
.approximately .60 .ml/hr .over .the .last .2 .days, .but .he .has .had .a .recent .change. .He .has .had
.300 .to .400 .ml/hr .of .urine .output .over .the .last .several .hours. .The .urine .has .a .specific
.gravity .of .1.002. .The .nurse .checks .his .serum .glucose .and .finds .that .it .is .100 .mg/dl. .The
.cause .of .hypernatremia .in .this .patient .is:
A.
sodium .retention.
B.
water .loss.
.C.
water .gain.
.D.
aldosterone .excess. .- .correct .answer.B. .water .loss
This .case .is .an .example .of .diabetes .insipidus, .which .is .caused .by .a .lack .of .antidiuretic
.hormone .(ADH). .ADH .causes .water .retention .in .the .renal .tubules .but .not .sodium
.retention, .so .eliminate .sodium .retention. .A .lack .of .ADH .causes .water .loss .not .water .gain,
.so .eliminate .water .gain. .Diabetes .insipidus .does .not .have .anything .to .do .with
.aldosterone. .The .hypernatremia .is .a .concentration .effect .caused .by .water .loss. .This
.sometimes .is .called .hypovolemic .hypernatremia.
A .patient .is .admitted .with .unstable .angina. .He .has .a .long .history .of .hypertension .and
.coronary .artery .disease. .The .nurse .notes .a .split .S2on .expiration .and .a .single .S2 .on
.inspiration .during .cardiac .auscultation. .Blood .pressure .is .150/88 .mm .Hg, .and .heart .rate
.is .88 .beats/min. .On .the .electrocardiogram, .there .is .a .normal-appearing .P .wave .in .front .of
.each .QRS .complex, .the .PR .interval .measures .0.2 .second .consistently, .and .the .QRS
.complexes .measure .0.14 .second. .They .are .positive .in .V5 .and .V6 .and .negative .in .V1 .and
.V2. .These .findings .most .likely .indicate .which .of .the .following?
A.
Left .bundle .branch .block .(LBBB)
.B.
Right .bundle .branch .block .(RBBB)
.C.
Third-degree .atrioventricular .block
.D.
Ventricular .tachycardia .- .correct .answer.A. .Left .bundle .branch .block .(LBBB)
Features .of .LBBB .described .here .are .a .QRS .complex .greater .than .0.12 .second .in
.duration .and .a .QRS .complex .that .is .positive .in .leads .V5 .and .V6 .(consider .these .left
.ventricular .leads) .and .negative .in .leads .V1 .and .V2 .(consider .these .right .ventricular
