USMLE step 3 CCS cases list
Other step 3 CCS resources
Usmle step 3 CCS (clinical case study) is part of the USMLE Step 3 exam. While it is half a day in a 2 day exam, it causes most of the anxiety associated with Step 3 exam for most test takers. A good understanding of the cases and the software used is essential to aid in the proper understanding of the exam. Here is a comprehensive list of CCS cases that can be edited and improved by Test takers. The are some appreviations: (yom = year-old male, yof = year old femal). If you find any mistakes, you can go ahead and edit the page! Part 2
Tasks for this page
Please make each case a separate page and add additional wiki and external links. (To add a wiki link all you need to do is enclose the word or word combination in parenthesis [[like this]] and it will be like this
Add additional cases, improve the existing cases.
The best way to learn is to to teach. If you are seriously preparing for step 3, post a case you are having some doubts with and we would collectively solve it.

Schedule office appointment 2. If patient continues to have panic attacks at a later time/date, consider drug treatment with Benzodiazepines, SSRI, TCA, MOAIs, Treat for 8-12 months. Consider adding cognitive and behavior therapies as combination is superior than either one alone. SSRI are considered the initial drug of choice i.e sertraline.Step V: Educate patient and family:Avoid caffeine and medications that can cause panic attack including: yocon, pondimin, flumazenil, cholecystokinin, and isuprel.STEP VI: Final DiagnosisPanic Attack
This case is from a CD that is being sold at http://www.passfirst.com the CD claim to have all 5 cases of usmle sample solved like this one and multiple questions. I don't know how good this CD is. If anyone has used it please let us know if is worth the price.NOTE: FOR COPYRIGHT REASONS, WE ARE NOT ALLOWED TO REPRODUCE THE QUESTIONS. YOU MAY HAVE TO DOWNLOAD THE TEST FROM THE USMLE'S WEBSITE, AND INSTALL THEM ON YOUR PC BEFORE YOU REVIEW THIS SOLUTIONCASE #1: 65-year-old white man with chest painCase Introduction: Essential Facts• Patient is white, in mid-sixties• Has sharp, right-sided chest pain, accompanied by respiratory distress• He was brought to the emergency departmentCommentsThere is nothing that connects being white with having chest pain. This patient could have been of any racial origin and still present with these clinical features. However, the patient’s age will affect our choice of differential diagnoses. Chest pain in an older man is more likely to be of cardiac origin than the same pain in young patients.Possible differential diagnoses at this stage include• Pulmonary embolism (PE) because of chest pain, respiratory distress• Lobar pneumonia (chest pain, respiratory distress)• Tension pneumothorax (chest pain, respiratory distress)• Musculoskeletal chest pain (pain in a specific location)• Pleuritic chest pain• Cardiac pain (this is less likely, though possible. A patient with dextrocardia who develops myocardial infarction may have right-sided chest pain. However, since this test is based on clinical conditions commonly seen in practice, we are not going to be too concerned with this differential)Initial Vital Signs: Essential Facts• There is tachypnoea and tachycardia• Blood pressure is low• Temperature is normal• The patient is obese (BMI of 29)CommentsPneumonia as a cause of this patient’s chest pain is effectively ruled out because of the normal temperature. Still high on our list are PE, pneumothorax, and the other differentials listed above. Patient’s obesity will be addressed at a later timeInitial History: Essential Facts• Chest pain began 10 minutes before arrival at the ER• This is the first episode of chest pain• Patient has had chronic lung diseases that may predispose to pneumothorax• Chest pain increases with respiration• He was not involved in strenuous activities immediately before the onset of chest pain CommentsAlthough, this pain increases with respiration, a musculoskeletal cause is unlikely, going by the patient’s recent history. He is an accountant who suddenly developed an excruciating chest pain while at work. There is no recent history of chest trauma.Because of his long-standing history of asthma and emphysema, we will add emphysema to his differentials, since the latter can cause a measure of chest discomfort, especially if there is associated chronic obstructive pulmonary disease (COPD). However, uncomplicated emphysema does not cause sudden sharp chest pain.It is time to perform the physical examination. Click the button labeled Interval History or PE and select • General Appearance• Chest/Lungs and • Heart/CardiovascularWe are interested in the general appearance (this is standard when interacting with most patients. You should always examine the patient’s general appearance). Moreover, because the primary complaint is in the chest region, we would naturally want to examine that area. Also, considering the patient’s age and the possibility that his heart might be the cause of his problems, we want to examine the heart as well. We cannot do more detailed examination of other systems because this is an emergency. Press OK to confirm your choice.History and Physical: Essential Facts• Patient is cyanotic and in marked respiratory distress• There is chest asymmetry, with hyper-resonance on right side. Breath sounds are also absent on that side• Cardiac examination essentially normal• Peripheral pulses present but weak• No pulsus paradoxus (a fall in pulse amplitude with quiet inspiration)CommentsNotice the results of physical examination. We seem to have enough reason here to believe that this patient has tension pneumothorax. However, we would still like to confirm this with further tests.FAQ: Since this patient is in severe pain, and his vital signs are abnormal, why can’t we just go ahead and treat?Answer: Although this is a relative emergency, it is clear that we have enough reason to investigate the cause of the patient’s problems further before we initiate treatment. First, we can still measure his blood pressure (although this is low). There is no pulsus paradoxus. We are not going to waste time on nonessential investigations however. It is important to try and establish the cause of patient’s problems, if possible, before we initiate treatments.Now, let us write orders. If the result of the History and Physical is still visible, click OK to close it. Next, click the button labeled Write Orders or Review Chart.Next, click Order button at the bottom of the screen, and enter the following orders (one on each line):• Chest x-ray• Oxygen• Morphine• ECGConfirm the orders by clicking the Confirm Order button. For chest x-ray order verification, choose Chest x-ray, portable. Click OK. Urgency: stat.Note: Although, Chest X-ray PA/lateral may give you more detailed information, it takes more time. Moreover, the patient has to be wheeled to the X-ray department before the films can be taken. Portable chest x-ray can be done right there at the ER, and it takes very little time.For oxygen, choose Inhalation for route and Continuous for frequency. For morphine, choose Intravenous for route and Continuous for frequency. Note: morphine is almost always given through the intravenous route for most conditions. In any situation where you have need to use morphine, consider this fact. Don’t let the frequency that we chose mislead you. Continuous administration here means that it is given at fixed times (e.g. 6 hourly, 8-hourly, etc).For ECG order verification, choose ECG 12-lead; Urgency: stat. Now that we have initiated treatment, it is time to review that patient with the next available result. From our Order Sheet, we can determine that the result of the portable chest x-ray will be ready within 10 minutes. So let us advance the clock to that time.Click the button Obtain Results or See Patient Later at the top of the screen, and choose Review Patient with Next Available Result. The test result is displayed.Chest X-ray findings: Right tension pneumothoraxNext, we are going to write more orders for this patient. Click the Order button at the bottom of your screen and type thoracentesis. Scroll to the bottom of the form and choose Thoracostomy tube. Confirm your choice. The result of this procedure is immediately displayed. When you click OK, the result of the 12-lead ECG will be displayed, showing essentially normal findings.It is now time to advance the clock, so we can re-evaluate our patient in 15 minutes. Click on the clock at the top of the screen and choose • Re-evaluate case In, then • type 15 in the Minutes box (you may also use the upward pointing arrow to do this). Click OKNow that our patient has been stabilized, we would like to perform an interval follow up before we admit him for further management.Towards the left side of the screen, click Interval History button, and choose • Interval Follow Up, • Chest/Lungs under the Physical Examination sectionThe important findings this time are:• Patient is a smoker (for 45 years)• He has a positive family history of cardiac disease, hypertension, obesity, and stroke. • As noted earlier, the patient is obese (he has a body mass index of 29)• Patient does not engage in regular exercise (dyspneic after 1 minute of brisk walk)• The chest is now symmetricalSome of this information will come in handy when it is time to address the patient’s health maintenance issues. For now, we would like to send him to the intensive care unit. FAQ: Since the patient has been stabilized, why can’t we just admit him to the ward instead of the ICU?Answer: Under the British medical care system (and, incidentally, this is also true of many third world countries), we would have sent the patient to the ward. However, in the United States, patients like these are sent to the Intensive Care Unit. FAQ: Why can’t this patient be discharged home right away, since he has been relieved of his problems?Answer: he has a chest tube in place. The general consensus is that the chest tube should remain in place until we are sure it is no longer needed (i.e it does not show any bubbles in the water seal.) Even then, some hospitals prefer to clamp the tube and observe for some more time, before they remove the tube entirely. Click the Change Location button, and select Intensive Care Unit (ICU). Confirm move. Recorded vital signs are displayed (much better this time around). Click OK.We must now add more treatment for the patient. Click Order Sheet on the left side of the screen, and Order button at the bottom. Enter the following orders (one per line):• Albuterol (inhalation, continuous)• Atrovent (inhalation, continuous)• Advise patient, smoking cessation (routine, start now)• Advise patient exercise program (routine, start later)• Advise patient, weight reduction (routine, start later)Next, we are going to re-evaluate the patient in 1 day. Click the clock, and advance the next evaluation to 1 day. The dialog appears telling you you have five minutes more, and asking for the final diagnosis.Final diagnosis: Tension pneumothoraxEnd of case
History of present illness:A 59 year old man involved in MVA, chest impacts the steering wheel, comes in with distant heart sounds, dyspnea, obtundation.Vital signs- BP. Pulse, RR, Temp.This patient requires Step I with ABCD.With Steering wheel injuries one should be concern about fracture of sternum, ribs, trauma to lungs, spleen, Liver, and myocardial contusion. This patient with distant heart sound give you the clue to possible pericardial effusion. Signs of cardiac tamponade include, the following: distended neck veins, decreasing blood pressure, narrowing pulse pressure, muffled heart sounds, pulses paradoxus, and equalization of hemodynamic pressures (CVP).Step I : Emergent management: A, B, C, D- Supplemental oxygen , Cardiac monitoring, Intravenous access Step II : Physical Examination General appearance HEET/Neck- check for distended neck JVDHeart/CV- Distant heart soundChest/Lung, Abdomen, Extremities, Neuro.Step III : Diagnostic Investigations: 1.

CBC2. Chem-73. Type and cross match4. Continueous monitoring of vital signs, oximetry, EKG2. Order CT SCAN of head without contrast. 3. Move the clock and get results. 4. If CT Scan shows epidural or subdural hematoma and patient is stable get Neurosurgical consult for Emergent Evacuation of the Hematoma.5. If patient is unstable due to increased inracranial pressure do #4 and start IV mannitol. If not effective then #66. Intubate the pt. and hyperventilate to pCO2 of 35mm Hg Step IV: Decision about changing patients location 1. Patient with Neurologic signs should have emergent surgery. 2. Neurological check up every 1 hrs . 3. Repeat CT afetr 24 hrs. If CT is Normal and patient is stable move home with office follow up in 5-7 days.STEP V: Educate patient and family:Patient with head trauma and initial normal CT should be informed to return to hospital Immediately if he develops Neurologic signs which requires Emergent CT.STEP VI: Final Diagnosis.Epidural Hematoma
History of present illness:40 year old homosexual female, cough and fever, vaginal itching . Note where the patient is on presentation, if she is in your office after initial work up, patient should be transferred to Ward or ICU (depending on presentation but most likely to ward). Unless the symptom are mild in that case treat patient in the office. VITAL SIGNS- will help you to determine if patient is stable or unstable. BP (N= 90-140/60-90), Pulse (N= 60-90, Mean- 72), RR (N= 12-20, Mean- 16), Temp.( N= 37C, 98.6F)Allergy: NKADDX- Pneumocystis pneumonia- Top of your list because of risk factor and OI at presentation.CytomegalovirusKaposi Sarcoma Legionellosis Lymphocytic Interstitial Pneumonia Mycoplasma Infections Nocardiosis Bacterial Pneumonia Fungal Pneumonia Viral Pneumonia Pulmonary Embolism Tuberculosis Step I : Emergent management: A, B, C, D- depending on presentation and assessment of O2 sat. if O2 sat is low. Start with one litter O2 and get IV access.Step II : Physical Examination Any suspect HIV/AIDS patient should have a complete physical exam. General appearance, Skin, Lymph Nodes, HEET/Neck, Chest/Lung, Heart/CV, Abdomen, Genitalia, Extremities, Neuro.Step III : Diagnostic Investigations: 1. O2 sat.- Pulse oximetry is obtained as part of the initial workup2. ABG- with signs of respiratory distress.(hypoxemia)3. LDH- Levels are noted to reflect disease progression. High levels during treatment indicate therapy failure and worse prognosis.4. CBC/D- 5. Chem-126. CXR- The classic finding is diffuse central (perihilar) alveolar or interstitial infiltrates. Normal CXR is found in 5-10% of cases.7. Sputum- by-sputum induction for Wright-Giemsa stain or direct fluorescent antibody (DFA) for Pneumocystis if PCP is strongly suspected. If negative and PCP suspicion is high next step is bronchoalveolar levage.8. HIV test- when you order a test like HIV that requires patient consent, it will tell you that patient consented to the test and result will be available in 7 days.9. CD4 count10. PCR assay11. Saline or KOH Vaginal secretion (wet mount).12. LFTs13. VDRL, Toxoplasma IGG, and hepatitis B and C serologies.14. Cervical papanicolaou Smear15. TB skin test.Treatment: 1. IV fluid –NS (In moderate- severe cases). 2. If suspicions is high for PCP start treatment with Bactrim-DS po bid for 14-21 days. If patient is hypoxic, start with Bactrim IV.3. Report positive result to Department of Health and Human services.Step IV: Decision about changing patients location 1. Mild-to-moderate disease refers to patients with milder symptoms and a nontoxic clinical appearance. They generally are not hypoxic and may even have a normal CXR. Outpatient oral therapy can be considered for these patients.2. Moderate-to-severe disease describes patients with severe respiratory distress, hypoxemia, and, often, a markedly abnormal CXR. Inpatient management with rapid diagnosis and treatment is essential.3. Admit patient to ward for moderate to severe disease. (ICU if patient unstable). Mild cases should be managed outpatient. 4. Discontinue IV fluid if patient is taking po and is not dehydrated.5. Continue Bactrim - 6. Treat Vaginal candidiasis with antifungal such as nystatin, clotrimazole, miconazole vaginally. 7. When diagnosis of AIDS is established start Antiviral therapy with: A. 2 NRTIs + 1 or 2 PIs. B. 2 NRTIs + an NNRTI8. Vaccines: Influenza, Hepatitis A and B, Pneumococcal vaccine.9. when patient is stabilized cancel IV fluid, move patient to home with follow-up in your office in 5-7 days.10. Continue Bactrim and antifungal- discontinue antifungal when patient returns for follow –up unless symptoms still persist in that case consider changing antifungal.Step V: Educate patient and family:1. Educate patient on safe sex. 2. Educate patient on Medication compliance.3. Console patient on HIV support group. When you request this option it tells you arrangements for follow-up has been make.Step VI: Final Diagnosis:Pneumocystis Carinii Pneumonia (PCP) with Candida Viginitis
History of present illness:63 years old man brought to Emergency Room complaining of colicky abdominal pain.When reading HPI note following:VITAL SIGNS- make sure patient is stable- BP (N= 90-140/60-90), Pulse (N= 60-90, Mean- 72), RR (N= 12-20, Mean- 16), Temp.( N= 37C, 98.6F)Allergy: NKADDX- Bowel obstruction, -carcinoma Pseudo-obstruction (ileus)Giant sigmoid diverticulumConstipationStep I : Emergent management: ABCD- Not neededStep II : Physical Examination General appearance Abdomen- Examination reveals a tympanitic/distended abdomen, and a palpable mass may be present. Severe pain and tenderness suggests ischemia/perforation. Bowel sounds are usually absent.Rectal exam- Rectal examination shows only an empty rectal ampulla. Skin, Chest/Lung, Heart/CV, Extremities, Neuro.Step III : Diagnostic Investigations: 1. CBC- Leukocytosis (in some cases Leukocytosis may be absent)2. Chem 7- to evaluate any electrolyte abnormality3. X-ray of Abdomen- Diagnosis of sigmoid volvulus can be made by using plain abdominal radiographic findings Plain radiographs show a markedly distended sigmoid loop, which assumes a bent inner tube or inverted U-shaped appearance, with the limbs of the sigmoid loop directed towards the pelvis. Also dilated gas-filled lumen, can result in a coffee bean–shaped structure; this is the coffee bean sign. 4. If diagnosis is questionable Barium Enema will confirm diagnosis but is contraindicated in suspected perforation.Treatment: 1. IV access- IV Fluid with LR2. GI consult- reason for consult, evaluation and decompression of possible sigmoid Volvulus.3. Sigmoidoscopy- decompression and untwisting of the sigmoid loop with placement of long soft tubeStep IV: Decision about changing patients location 1. Admit to ward2. Continue IV fluid3. Monitor patient for 2-3 days after decompression for persistent abdominal pain and bloodstained stools, signs that may herald ischemia and indicate the need for surgical intervention.4. Consult General surgery- Surgery is reserved for patients in whom tube decompression fails or for those in whom signs of ischemia are suggested. Surgery also has a role in an elective situation when the volvulus repeatedly recurs.5. After patient is stabilized, move patient home with office follow-up in 5-7 days. Step V: Educate patient and family:Console patient to seek medical care if Nausea, Vomiting , Rectal bleeding or abdominal pain reoccur.Console on low fat, high fiber diet.STEP VI: Final DiagnosisSigmoid Volvulus

History of present illness:A 14 yr AAF girl with profuse vaginal bleeding comes to ER. She had her menarche 3 months ago and had irregular bleeding since then.1. Note vital signs: BP, Pulse, Resp. Rate, Temp. 2. Check vitals to make sure pt is hemodynamically stable. If patient unstable do step I.For any female with abnormal vaginal bleeding you should check:1. age of the patient2. Family history of bleeding disorder3. history of irregular cycles4. evidence of bleeding problem on physical exam i.e. petechiaDifferential diagnosis of vaginal bleeding 1. dysfunctional uterine bleeding secondary to anovulation2. endometrial neoplasia3. endogenous source of estrogen i.e. granulosa cell tumor4. uterine myomas with submucous myomas5. hematologic disorders such as leukemia and idiopathic thrombocytopenia6. endometritis and endometrial polypsIn this 14 year old female with h/o irregular cycles and no other signs on physical exam you should think of DUB secondary to anovulation which usually occurs in extremes of reproductive age, menarch and perimenoposal women. Step I : Emergent management: A, B, C, D- if patient stable move to stepIIStep II : Physical Examination Do a focus PE: general, skin, chest/lung, heart, abd, genitalia, extremitiesStep III : Diagnostic Investigations: 1. Pregnancy test2. CBC- will show Hgb 7.0 – do cross and match if patient is hypotensive or symptomatic start IV access and consider NS3. Chem 12 (glucose included), coagulation profile, TSH, ESRMost likely in this case all test will be neg. except abnormal CBC. Treatment: This patient is bleeding profusely and her Hgb is 7.0 so start estrogen IV 25mg q4h x3. And Ferrous sulfate 325 mg. Po tidBleeding should stop. Recheck CBC.Step IV: Decision about changing patients location 1. Move patient to ward because her Hgb is low.2. Repeat CBC following day and start OCP3. MVI one daily 4. Continue ferrous sulfate 325 po tidIf patients Hgb is stable discharge patient home with office follow up in one weekConsult on safe sex.In office repeat CBC if has improved follow up in 3 weeks at that time you may D/C OCP and iron pills if you want to. ( 3 weeks of treatment is recommended with OCP). If patient desires you can continue OCP.Final diagnosis:DYSFUNCTIONAL UTERINE BLEEDING
History of present illness:A 79 year old female comes to your office complaining of forgetfulness. The first and most important initial evaluation of patient with dementia is History and Physical examination. Important clues such as onset, duration, etc.. will narrow your diagnosis and required investigating labs.Note vital signs- BP (N= 90-140/60-90), Pulse (N= 60-90, Mean- 72), RR (N= 12-20, Mean- 16), Temp.( N= 37C, 98.6F)Allergy: NKADDX:Alzheimer’s dementia- Most common.Vascular dementia- 2nd Most common.Pick’s disease –3rd most common.Lewy body diseaseHuntington’s diseaseParkinson’s diseaseHIV- Related dementiaHead trauma related dementiaStep I : Emergent management: A, B, C, D- Not needed.Step II : Physical Examination General appearance, Skin, Lymph Nodes, HEET/Neck, Chest/Lung, Heart/CV, Abdomen, Extremities, Neuro/Psych.Step III : Diagnostic Investigations: There are several diagnostic investigations for workup of dementia but H&P exam will narrow the list.1.
