ABSITE 2025 QUESTIONS AND
ANSWERS 100% CORRECT!
Nerve implicated in Frey syndrome — parasympathetic postganglionic fibers to parotid -
ANSWERSAuriculotemporal nerve
Management recommendations for BRCA and don't want children or any more -
ANSWERSBSO, bilateral mastectomy, HRT until 50
Next step for spontaneous skin ulceration in arm in post modified radical mastectomy
patient - ANSWERSIncisional biopsy because likely lymphangiosarcoma/Stewart-
Treves syndrome and therapy will be WLE +/- isolated limb perfusion
First line treatment for acute limb ischemia of the lower extremity -
ANSWERSPercutaneous transluminal angioplasty unless long segment or multiple
segments, then open approach
Technique for SMA embolectomy - ANSWERSTransverse incision of proximal SMA,
just distal to middle colic, 2-3 fogarty proximal and distal, close with interrupted prolene
Is BRCA1 or 2 higher risk for breast cancer? For ovarian cancer - ANSWERSBRCA 1
for both
Organism associated with human bites - ANSWERSEikenella corrodens
Organism associated with lymphangitis - ANSWERSStrep pyrogenes
Management for rhabdomyolysis - ANSWERSIV fluids and alkalinization of the urine
How is vitamin K synthesized in the body? - ANSWERSColonic bacteria
Anticoagulation recommendations for mechanical and bioprosthetic valves -
ANSWERSMechanical must be on vit K anticoagulant w/target INR for aortic and high
risk mitral 3 and 2.5 for others, and add low dose asa if low bleeding risk. Surgical
aortic: asa for 3 mo, and surgical mitral or tricuspid vit K anticoagulant x3 mo, and low
dose asa indefinitely for these if low bleeding risk. Transcatheter aortic: dual anti-plt
therapy 3-6 mo and low dose asa indefinitely
Pathophysiology of gynecomastia - ANSWERSDecreased androgen production and
either increased estrogen production or estrogen precursors are the main cause. Also
can have decreased androgen to receptor binding and increased androgen binding to
sex hormone binding globulin
, Octreotide mechanism of action for varices treatment - ANSWERSSplanchnic
vasoconstriction and decreases portal htn
Liver abscess treated with flagyl - ANSWERSAmoebic liver abscesses from entamoeba
histolytica
Liver abscess treated with albendazole - ANSWERSHydratid liver cysts
Treatment for resectable gallbladder carcinoma - ANSWERSTis and T1a (invasion of
lamina propria) chole is sufficient. T1b-T3 chole + 4b/5 hepatectomy, and regional
lymphadenectomy
pH changes by how much with a change in PaCO2 of 10 mmHg - ANSWERS0.08
Contraindications for ketamine - ANSWERSAngina/ischemic heart disease because it
increases sympathetic nervous system increasing myocardial O2 consumption. Also
contraindicated in space-occupying brain lesions and increased IOP
MOA of desmopressin - ANSWERSStimulates endothelial release of factor viii and vWF
MOA of propranolol for asymptomatic prophylactic treatment of esophageal varices -
ANSWERSNon-selective beta blockers inhibit beta2 receptors inhibiting vasodilation is
splanchnic circulation, and they decrease cardiac output with beta 1 blockade
Pager-schroetter syndrome - ANSWERSExercise induced thrombosis of the subclavian
and axillary veins
Pathway of beta 2 stimulation - ANSWERSGPCR that activates cAMP
Receptors that dobutamine activates - ANSWERSBeta1 with low dose and beta2 higher
doses
SMA site of occlusion for embolic vs thrombotic etiology and pattern of ischemia -
ANSWERSEmbolic usually distal SMA and causes ischemia from mid-jejunum through
transverse colon. Thrombotic is usually proximal SMA and causes ischemia from
proximal jejunum through transverse colon. Embolic spares proximal jejunal branches
Management of mediastinitis - ANSWERSOpen debridement and pectoral muscle flaps
What do you give for beta blocker overdose? - ANSWERSglucagon
What is first line treatment for diltiazem overdose? - ANSWERSInsulin -- those
refractory can be treated with lipid emulsion therapy or transcutaneous pacing
Most common organism cultured from septic thrombophlebitis 2/2 contiguous severe
pharyngitis or peritonsillar abscess - ANSWERSFusibacterium necrophorum (gram
