NBME 12 Flashcards
CARDIAC amyloidosis
only restrictive type will only hear s4
vs
chronic htn leading to CHF can have both S3 AND S4 d/t htn causing hypertrophy
pt with NG tube and cloudy fluid draining from it
next step?
CT scan of sinuses
IV abx, remove NG tube d/t bacterial sinus infection
pt gets surgery, given hydromorphone then becomes hypotensive, low resp rate, miosis (3mm pupils)
opiod (hydromorphone) intoxication
causing hypercarbia
check ABG anlaysis
acetaminophen:
ibuprofen:
colchicine:
acetaminophen: given FIRST initially to pts with osteoarthritis
ibuprofen: given Next to osteoarthritis (as well as topical diclofenac)
Colchicine: given in GOUT! or arthritis
NSAIDS(ibuprofen or colchicine): pseudo gout
prego on lithium, what next?
continue taking lithium
fetal cardiac ultrasound (ebsteins: R ventricular atrialization)
Neurofibromatosis 1
AD ch17
cutaneous neurofibroma (derived from neural crest cells)
cafe au lait spots (hypo-pigmented)
inguinal/axillary freckling
Lisch nodules – pigmented iris hamartomas
optic gliomas
pheochromoctyoma
**annual: Opthalmic, neurologic, dermatologic, blood pressure monitoring, bone/growth monitoring
7yo girl with precocious puberty and left ovarian mass
next step?
surgical resection: left oophorectomy
precocious puberty can be central vs peripheral (this is peripheral)
5yo with recurrent sinusitis, pneumonia, and on imaging:
primary ciliary dyskinesia (sinusitis, brochiectasis (bronchitis), inferitiliy, situs invertus)
kartagener
bronchiectasis in image
not able to mucus clearance
vs
wiskot aldrich will see WATER
VS
LAD: will see ELEVATED leekocytes since porblem is adhesion not making it
Repeated neisseria infections
compliment deficiency furhter down cascade
Slipped capital femoral epiphysis (ages 10-15) and overweight: painful limp, limited ABDuction and internal rotaitn of hiop
can cause avascular necrosis, premature osteoarthritis, gait impairments
tx: surgical stabilization of femoral head
normal S1 but diminished S2
harsh, systolic murmur
weak and delayed peripheral pulses
aortic stenosis
pulsus parvus et tardus
S2 from weakened closing of the valve
early onset 40 to 60: congential bicuspid valve or chronic rheumatic heart disease
older than 60: calcification and fibrosis
anal fissures longer than 8 weeks treatment:
chronic fissures: surgical repair
acute: topical analgesics, vasodilators, sitz bath
HTN, tachycardia, pupillary dilation, restlessness, euphoria (hallucinations, paranoia)
vs
”” “” + yawning, lacrimation, rhinorrhea, piloerection
cocaine intoxicaiton
vs
opioid withdrawal
prego 36 weeks, in labor, moderate blood, mom is A Rh-Negative
serum anti-D antibody titer is positive
fetal heart montior: SINUSOIDAL wave forms
what is most likely causing fetal heart rate pattern?
Rh isoimmunization
Rh(D)-negative moms are at high risk of forming anti-Rh(D) antibodies (Rh isoimmunization) – if exposed to blood from a Rh(D)-Positive fetus
it can cause hemolytic anemia – erythroblastosis fetalis (sinusoidal wave forms) 2/2 to Rh isoimmunization
next baby will die
Prevent it by giving RhoGAM at 28 weeks in Rh(D)-negative mothers
Pt who is able to sleep at night totally fine, (might see cataplexy or hallucinations hypno-gogic/pompic) but has daytime somnolence
dx?
Narcolepsy: loss of orexin-A/B (found in hypothalamus that promote wakefulness and inhibit REM sleep)
dx:** multiple sleep latency tests **will see shorter time from wakefulness to initiation of REM sleep
can also do lumbar puncture to measure orexin A in CSF
pt with bipolar on lithium, gets hypothyroid sxms with elvated TSH, anti-thryoid peroxidase antibody is negative
lithium induced (ae)
do not stop lithium, just treat hypothyroidism
kidney stones in a kid
dx
size/tx
do ultrasound/xray since CT is more radiation
if larger than 6mm –> needs more intervention (lithiotripsy)
if smaller: oral hydration and analgesia
50s with muscle weakness fatigue, bilateral ptosis, cxr: mediastinal mass
Dx?
myasthenia gravis
anitbody against nicotinic acetylcholine receptors at neuromuscular junction
thymoma
dx: nerve conduction studies with reptitive stimulation (like lambert eaton)
tx: complete thymectomy, ach-inhibtors with immune modulating therapies
acute chest pain, SOB, hypoxemia
ABG: acute resp alkalosis, hypoxemia, increased A-a gradient
next step?
Pulmonary embolism
increased A-a gradient d/t ventilation-perfusion mismatch
dx: CT-A,
thrombolytis and anticoagulants
bone, pain, anemia, hypercalcemia, renal dysfunction
dx?
roloux formation RBC aggregation
Multiple myeloma: neoplastic proliferation of plasma cells (overporduce monoclonal immunoglobulin light or heavy chains)
serum protein/urine electrophoresis
diagnosis confirmed with: **bone marrow biopsy
triad: digital clubbing, periostosis (inflamed periosteum of long bones), and severe arthralgia
Hypertrophic Pulmonary osteoarthropathy
abnormal fibrovascular proliferation
hypoxemic changes
unilateral lung mass with perihilar lymphadenopathy (malignancy cause but can be d/t anything)
adolescent with high BMI, what can improve mortality next 10 years?
weight loss
firm tender erythematous edematous mass on angle of mandible
acute suppurative parotitis
mixed oral flora or Staph Aureus
elderly dehydration, poor dentition, low saliva
dx: cliinical, lor with u/s or CT scan further evlauate for complicaitons: abscess/tumor
1 hr after transfucion of PRBC’s pt becomes flushed with fever, but normotensive and normal heart rythm&rate
next step?
Febrile nonhemolytic transfusion reaction
release of cytokines from leukocytes during blood product storage (long time storage of blood proudcts)
prevent: prestorage luekoreduction
tx: stop transfusion
give** oral acetaminophen** *pyretics
vs
ibuprofren: can cause gastritric/duodenal ulcers especially if pt already has ulcers
vs
epinephrine, diphenhydramine, methylprednisone – given in anaphylaxis with blood product transfusion in IgA deficiency: wheezing, uritcaria, hypotension, tachy
pulsatile nontender mass in inguinal region
when to do surgery?
femoral artery aneurysm
dx: duplex ultrasound of groin or CT-angio
symptomatic or larger than >3cm – surgical artery repair
ct scan: intertitial lung pattern
FVC: 48%
DLCO: 55%
dx?
Intersitital lung disease
lung biopsy
vs
sarcoidosis can cause ILD: but measuring ACE would not be specific/sensitive enough for diagnosis
IgA deficiency
next step? tx
can be asymptomatic, recurrent sinopulmonary infections or otitis media, or anaphylactic reaction to Plasma blood
tx: only for symptomatic infection or anaphylaxis
no intervention indicated at this time
partial or complete small bowel obstruction
next step?
abdominal x ray : dilated loops with multiple air fluid levels
managment: bowel rest, IV hydration,
complete obstruction “ “ + if it does not resolve on its own – ex lap
