STEP 2 part 2 Flashcards
What is the next best diagnostic test for Mesenteric ischemia?
CT Angiography
What is the management of myocarditis?
Supportive with use of diuretics, ACE inhibitors, and nitroglycerin.
What are the major differences between Progressive Supranuclear Palsy and Parkinsonian sndrome?
in PSP tremor is less common, rigidity tends to be more axial than peripheral.
When is a CT scan indicated prior to performing a lumbar puncture? (6)
- Immunocompromised state
- Prior CNS disease
- New onset seizure within one week of presentation
- papilledema
- decreased level of consciousness
- focal neurological deficits
What does legionella look like on microscopic examination?
Intracellular organisms when stained with silver stain.
What is the most common test used to confirm measles infection?
Measurement of acute and convalescent serum IgM and IgG antibodies.
What likely mechanism should be suspected in a patient who presents with apparent overdose with eye examination shows afferent pupillary defect, mydriasis, retinal sheen from edema, and hyperemia of the optic disk?
Methanol overdose
If a patient with recent liver transplant starts presenting with liver failure, and causes of organ failure such as Obstructive biliary process/ portal vein thrombosis have been ruled out, what should be done next?
Biopsy of the liver is necessary for definitive diagnosis.
What is the currently recommended antibiotic therapy for a hospitalized patient with community-acquired pneumonia?
Second or third generation cephalosporin, plus a macrolide or doxycycline or monotherapy with a fluoroquinolone for 5-7 days.
What is the treatment for patients with Alport syndrome?
Focus on control of hypertension – often accomplished with ACE inhibitors/ARBS
What is the rate and depth that ACLS should be provided?
Chest compression at 100 compressions/ minute and a depth of at least 2 inches.
What is the immediate treatment for patients suspected of having testicular torsion?
Immediate surgical exploration and detorsion.
What is the appropriate treatment for TTN?
Conservative management, maintaining appropriate thermal environment, bulb suction, blow-by oxygen if needed.
What is an endodermal sinus tumor and what tumor marker is commonly associated with it?
Yolk Sac Tumor
Alpha Fetoprotein (AFP) is associated.
What is the next step in management of a patient who presents with a clear diagnosis of Graves’ disease?
Atenolol
What is the first step in the process of hemodialysis?
Vein mapping.
What is the next best step in a patient who presents with symptoms of achalasia?
Esophageal manometry.
What are the EKG findings in a patient who has pulmonary hypertension?
- Right axis deviation
- Increased P wave amplitude
- Right ventricular hypertrophy.
What is the immediate treatment of a patient who presents with possible ALL and is febrile?
Antibiotics while diagnosis diagnosis is being confirmed.
What medication can prevent infection by RSV in infants?
Palivizumab
What type of murmur presents with a click and a late systolic crescendo, and what maneuver will increase the intensity of the murmur?
Mitral valve prolapse
Valsalva maneuver decreases venous return to the heart, results in decreased blood in the left ventricle, the prolapse occurs earlier and to a greater extent, augmenting the murmur.
What is the preferred initial test for a patient who presents with high pretest probability of DVT?
Compression ultrasonography.
What blood conditions can occur with patients who present with Infectious Mononucleosis?
- Autoimmune hemolytic anemia
2. Thrombocytopenia
What findings are found in Tricuspid valve atresia?
- Left Axis deviation on EKG
2. Decreased pulmonary markings on chest radiograph
