CCS for USMLE Step 3

The following is a general outline of several concepts that are discussed in CCS workshops. This is just for

quick review. Comprehensive explanation and demonstrations are available in CCS Workshops.

EMERGENCY ROOM GENERAL PROTOCOL:

Check follow-up Hx often in ER to monitor subjective improvement in the complaints.

Use control button on an ORDER screen to pick up several options. Always check report time of the order

after placing the order - this allow seeing how long the procedure or order will take

Algorithm for ER: ( Refer Powerpoint Slides)

Initial orders + pain management

Focused PE

Additional orders

Full exam once stable

Orders:

Oxy – oxygen – several options

IVA – IV access

Vitals – q1hr

Card – cardiac monitor,

Bmp – basic metabolic panel

Counsel: seat belt, safe sex, weight loss, exercise, contraception, breast exam, smoking cessation, low Na (for

HTN), diet, calorie – restricted (for HTN, obesity) – In ER Cases, reserve this routine counseling to 5 min

screen.

Algorithm for office:

Full Physical Exam

Treat the Symptom

Order labs and Send patient home (unless there are criteria for admission or unstable vitals or severe pain)

Schedules follow up appointment when diagnosis is likely to be available

Treat the diagnosis during follow up visit, check follow up history and focused physical during follow up

visit.

The following are several sample CCS cases subject-wise which were practiced in several previous

CCS Workshops at the request of the attendees. A selection of the sample CCS cases will be practiced

in the CCS Workshop. In addition, most of the Cases that are requested by the attendees will be

practiced during CCS Workshops. Discussion of NBME copyrighted cases is strictly prohibited.

Students are advised to kindly not discuss exam cases or kindly not disclose NBME or USMLE Step 3

exam questions during the CCS Workshops.

Pediatrics1. Newborn Down's baby. Get chromosomal analysis2. Duodenal Atresia: 1 day old Down syndrome baby presents with vomiting – ultrasound with duodenal

atresia. Get abdominal US, then General surgery consult.3. Ventricular Septal Defect. The child presents with CHF. Hx of Down syndrome. PE: pansystolic murmur.

Initial mngt: furosemide, CXR, echoKG, Cardiology consult to get cardiac catheterization to rule out

pulmonary hypertension even it is not read on echo report (because if you will close VSD there will be

no blood coming to the LV). If pulmonary hypertension is present you cannot close VSD, than the only

option is lung transplant.4. Constitutional growth delay in african american kid. Check bone age, genitalia to rule out cryptorchidism,

chromosome analysis to rule out Klinefelter syndrome and Turner syndrome.5. CHILD ABUSE: 3 y/o African American boy presents with lethargy, CXR reveals multiple posterior rib

OBGYN1. Pregnancy2. Pregnancy in a 44 yof. Check at first visit Pap smear, UA, CBC, blood type, Rh type and antibody screen,

RPR or VDRL (if positive confirm with FTA-ABS or MHA-TP), rubella titer (if unclear vaccination Hx),

HIV, glucose (if the pt has risk factors). Repeat at every visit UA. “Triple” screen (AFP + estriol + HCG)

the clock. Interval Hx: vitals are more stable, but the pt is still dizzy. Transfuse blood (acute anemia

<8 or symptomatic pt, e.g. SOB). Conjugated estrogen IV (work as a hemostatic agent). BT 9, PTT 44

(vWD: woman, prolonged BT and PTT, positive FHx). Give DDAVP, if the first dose did not work,

then give cryoprecipitate (it has more factor 8 than FFP). Check CBC q4hrs (should improve after

blood transfusion). Interval Hx: the pt continue to bleed, transfer to ICU. Pelvic US normal (no fibroid,

if positive needs Tx with uterine artery embolization or if the pt >45 yo - hysterectomy). Eventually

bleeding decreases, the pt feels better.

Postmenopausal woman with vaginal bleeding. If she is on HRT, she can have bleeding in first 6 months.

Get US, if hyperplasia >5 mm get endometrial biopsy. If it comes back negative, then progestin. If it

shown atypical hyperplasia do D&C or hysterectomy. If endometrial CA proceed with hysterectomy.8. Acute PID. Check ESR, CBC, vaginal Cx. Start cefoxitin + doxycycline for 2 wks outpatient or

for possible metastases). Abdominal US can help with abdominal aneurysm but not show dissection;

get abdominal CT with contrast (check creatinine before): shows AAA dissection. Start metoprolol. Get

lumbar spine x-ray. Complete PE: now back pain is better, but the pt has abdominal pain and dropped

BP (shock). Surgical consult for aneurysm repair, BPM, cardiac monitor, IVF. After OR transfer to ICU,

Cholesterol

Smoking

Alcohol

Obesety1. Obese man with essential HTN – evaluate for Sleep apnea, if positive nocturnal CPAP2. Obesity in a teenager. Check lipid profile. Low calorie diet.

DVT, PE1. Pulmonary embolism2. Septic pulmonary emboli in IVD abuser.

Acid base / electrolyte disorder1. Dehydration/ Hypernatremia - 70 y/o man with altered mental status, no urine output sent from NH

to ER. No fever. (BMP comes back shows NA + 160, BUN high, Crea normal) --> two things here ,

this patient has confusion which could be secondary to dehydration or hypernatremia. If euvolemic

hypernatremia with CNS symptoms --> you would use D5W IV. However, in this case there is a clue

that the urine output is low --> indicating hypovolemic hypernatremia --> so, would hydrate first with

NS , NG tube, free water orally, R/o sepsis ( if CBC showed leucocytosis or if there is fever - please

be sure to r/o sepsis , get CXR, blood cx, urinalysis and urine cx, if any source of infection seen start

empirical antibiotics pending cultures), get head CT, Foley catheter ( r/o obstructive uropathy since

there is no urine output), and next put orders to monitor pts response to your therapy ( I/O monitoring,

neurochecks q4hrs and BMP q4hrs - check if Na and BUN are improving, don’t drop Na too fast due to

risk of cerebral edema) 2. Hypercalcemia/ renal mass (likely RCC) - Elderly man presenting with fatigue, do physical, make sure he

is not dehydrated (if he is dehydrated, needs admission and IV fluids) - office visit - routine tests - BMP

reveals hypercalcemia - stop clock and start w/u on order sheet, i.e., PTH, Serum phos, ionized calcium,

LFTs (check alkaline phosphatase - increased level may indicate bone lesions), vitamin D level, SPEP,

U/A, UPEP, 24 Hr urinary calcium excretion ( to r/o familial hypocalciuric hypercalcemia. 24 hr urine

calcium is increased in primary hyperparathyroidism where as decreased in hypocalciuria), CXR (R/o

sarcoidosis - hilar adenopathy, R/O LUNG MASS, Cancer) . R/O metastatic cancer ( back pain, breast

mass etc) from the history itself - All come normal, so remember to r/o ectopic PTH secretion that is

seen as PTH related peptides (PTHrP is not picked up by the software) --> so, next do w/u for r/o occult

malignancies that can lead to hypercalcemia by ectopic PTH secretion (SQUAMOUS CELL LUNG

CANCER, SQUAMOUS CELL HEAD AND NECK CANCERS, BREAST CANCER, MULTIPLE

MYELOMA [UPEP/SPEP], T-CELL LYMPHOMAS, RENAL CELL CANCER, AND OVARIAN

CANCER ) -- > do a CT chest and abdomen (will help to r/o lung ca, lymphoma and renal cell ca) -

CT abdomen reveals a 10 cm renal mass ( make sure they say complex renal mass) - call nephrologist,

oncologist and surgeon - rx is nephrectomy which will resolve hypercalcemia ( but remember, if the

presentation revealed dehydration or coma or calcium > 13 gm% - suspect hypercalcemic crisis, admit

patient and hydrate first and then work up everything as inpatient! Give bisphosphonates for all cancer

related hypercalcemia)

Shock

Cardiology1. Acute pericarditis - rx (make sure to do echo, don’t do unnecessary pericardiocentesis if there is mild to

moderate pericarditis without clinical or echocardiographic evidence of tamponade) 2. Acute MI. ER: 65 yom, c/o severe left chest pain 10/10 which started at rest and radiates to the left

shoulder. Vitals are stable. PMH; HTN, PAD, AAA. Start with pain mngt: MONA = morphine IV x1,

oxygen, nitroglycerine sublingual x1, aspirin and tests: vitals, pulse oxymeter, IVA, cardiac monitor,

BMP, CXR, EKG 12 lead (the most important test), cardiac enzymes x3. Then get focused PE => normal

=> get full PE including rectal (the pt will probably need heparin). Advance the clock for EKG result,

shows STEMI (if it is negative, then you need to rule out non-STEMI with cardiac enzymes). Start

BBL (metaprolol; decrease mortality), clopidogrel, heparin x24 hrs, abciximab (Reopro; continue for

1 yr if there is a stent, if not then just for 1 wk), statin, cardiology consult for cardiac catheterization

(do thrombolysis with tPA only if cannot get cardiac catheterization promptly). It will give you EF

(if EF is low start ACEI) and show a blood clot. Check PT/PTT. Follow CBC for possible HIT, BMP

for possible contrast nephropathy, check lipid panel, check diet. Counsel for sex activitiy, exercise,

education, smoking. Get cardiac rehab. Get submaximal stress test in 1 wk after STEMI for exercise

recommendations (not used that often now). For non-STEMI (without cardiac catheterization) proceed

with full stress test in 1 wk if there is ongoing ischemia. If the pt cannot walk on the treadmill get

pharmacological persantine or depyridamole test.3. DM w/ MI4. Stable Angina5. atrial fib 6. Congestive heart failure in a post-op patient (make sure they are not giving too much IV fluids in post

op setting, I/O monitoring, daily weights, lasix, 2d echo, r/o MI, EKG, CXR, BNP - Lasix, if flash pulm

edema, give morphine) 7. complete heart block (MVA) – actually, MVA secondary to syncope from 3rd degree heart block.

Bradycardia / heart block mngt. Stabilizing orders before Dx: monitor cardiac, oxygen, pulse oxymetry,

check monitor cardiac, EKG 12 lead, ABG, blood pressure monitor (BPM), IV access. Check TSH,

cardiac enzymes, give midozalam to sedate the pt for transcutaneous pacer; consult cardiology, place

pacemaker transthoracic (transcutaneous). Then transfer the pt to the ICU, change the pacemaker to

transvenous (more stable); d/c any meds that decrease cardiac conduction (BBLs, ACEIs), then change

transvenous pacemaker to permanent (get cardiothoracic consult). Diet: normal. Counsel family/pt, seat

belt, medic alert button. Vaccine: influenza, pneumo. TEE to look for possible clots.

Endocrinology1. Secondary Hypertension, Hypokalemia – adrenal mass 2. Constipation, hypercalcemia, primary hyperparathyroidism 3. Hypothyroidism in a man. Office: 33 yom, c/o extreme tiredness and constipation for several wks.

yo]): delayed reflexes, obese, mild brady (may be normal in young person). DDx: hypothyroidism,

anemia, colon CA, hypercalcemia. Tests: TSH, CBC, LFT, EKG, UA, BMP, FOBT. Respond to sxs for

constipation: docusate, bisacodily, diet with high fiber. Send the pt home, schedule appt when results are

back. TSH 35 (you start with screening test, if it is positive, then do confirmatory tests; stop the clock,

order T3/T4). Order levothyroxin, thyroid peroxidase antibodies (antimicrosomal antibodies), lipid

profile (if LDL is elevated it might be caused by hypothyroidism, so don’t need to treat it right away, it

may improve on levothyroxine). Counsel: smoking cessation, side effects of medications, seat belt, safe

sex practice. Later check TSH and lipid profile in 1 month. Follow thyroglobin for effectiveness of Tx.

oxygen and pulse oxymeter, suction airway q1hr, vitals, IVA, cardiac monitor, BMP, thiamine IV,

accucheck, Tylenol level, CBC, UA, CXR, LFT, ammonia = 82, coags. Do paracentesis for cell count,

culture, cytology, Gram stain, protein (if WBC>250 the pt has SBP). Lactulose per rectum (the pt can

start responding after 1-2 bowel movements, so try not to intubate but secure airway. Levofloxacin for

SBP prophylaxis (ceftriaxone for SBP treatment). Neurochecks q1hr. BMP and CBC negative. PTT

prolonged, INR 1.5. After lactulose the pt is more awake, opens eyes. Very low AST, ALT, albumin

(means advanced cirrhosis). Don’t give albumin, it will not stay in the vessels and make edema worse.

Get EGD to look for varices, check AFP q6 months and US q6 months for future hepatocellular

carcinoma screening. SCDs for DVT prophylaxis.5. Acute cholecystitis 6. Inflammatory bowel syndrome (ulcerative colitis and Crohn disease). Office: 25 yom, c/o abdominal

antigen is more sensitive but takes more time), WBCs, Gram stain; CBC, ESR, BMP. Tx: loperamide

(but not for infectious diarrhea caused by Shigella or Clostridium difficele), check orthostatic, oral

electrolyte mixture, dicyclomine for abdominal cramps. Send the pt home, follow in 3 days. Gram stain

shows GNRs – normal bacteria in bowels (don’t be fooled; follow culture which will show normal flora).

WBCs elevated – an important sign of inflammation. ESR elevated, CBC normal. Follow-up: check

interval Hx, get focused PE: the pt still has diarrhea. Get colonoscopy, GI consult, low residue diet (less

fiber). Colonoscopy shows pseudopolyps. Tx: meselamine (later add steroids) or sulfasalazine.7. Erosive esophagitis/ GERD8. Acute pancreatitis9. 53 y.o.

hemolysis (r/o sickle cell at this time), do stool guaic (rectal exam in the beginning itself r/o blood loss

as a cause of Fe def) --> Fe defeciency diagnosed which is most common in children during growth

spurts if nutrition is not adequate ( remember you already ruled out other causes of Fe deficiency i.e;

lead poisoning, GI blood loss, ongoing hemolysis) . Order iron rich diet (very important to order this

diet since lack of balanced diet is the reason for Fe def in children during growth spurts) , iron oral

pills ( FERROUS SULFATE)- check cbc in 1 month/ schedule follow up visit - usually blood counts

return to normal in 2 months --> so, schedule follow up CBC and Ferritin level for "LATER" date i.e; 2

months later on 5 minute screen ( continue ferrous sulfate for at least 6 months even when blood count

normalized)
