STEP 2

Question 1

The normal range for Cardiac Index is

Answer 1

2.5 to 4 L/min/m2

Cardiac Index (CI) The cardiac index is an assessment of the cardiac output value based on the patient’s size. To find the cardiac index, divide the cardiac output by the person’s body surface area

Question 2

Clinical use(s) of fenoldopam

Answer 2

Fenoldopam is indicated for in-hospital, short-term (up to 48 hours) management of severe hypertension when rapid, but quickly reversible, emergency reduction of blood pressure is clinically indicated,

Has particular utility in pts with CKD, can prevent AKI

Question 3

emergent pharmacologic management of Torsades de Pointes?

Answer 3

mag sulfate

Temporary transvenous overdrive pacing to 100 beats per minutes is a second line management option if
intravenous magnesium sulfate proves ineffective.

Question 4

Timeframes that differentiates brief psychotic disorder vs schizophreniform vs schizophrenia

Answer 4

<1 mo = brief schizophreniform disorder

>6 months = schizophrenia

Question 5

do you use a viral sputum culture or a sputum viral panel by PCR to diagnose viral URTI

Answer 5

viral culture

PCR is faster, but lass sensitive and specific

Question 6

Which of the following findings most likely increases the risk of mortality for a pt with acute pancreatitis?

Leukocyte count: 19,000/mm3 (nml 4500-11,000)
Glucose concentration: 160 mg/dL
Serum amylase: 6900 IU/L (25x upper limit of normal)
Lipase: 350 IU/L (2x upper limit of normal)

Answer 6

leukocyte count

Question 7

Indications for emergency thoracotomy in patients with

blunt penetrating thoracic trauma

Answer 7

rapid exsanguination from
chest tube (>1,500 mL immediately return)
or
unresponsive hypotension (SBP <70 mmHg) despite vigorous resuscitation

this procedure can be used to gain control of hemorrhaging, release a cardiac tamponade, facilitate internal or open cardiac massage, and allow for cross clamping of the aorta.

Question 8

diagnostic test of choice for suspected bacterial respiratory infection

Answer 8

Urinary antigen tests (UATs) for S. pneumoniae and L. pneumophila (or less commonly Histoplasma capsulatum) have emerged as powerful tools for improving the diagnosis of bacterial respiratory infections
