Step 2 Ck - Classic Labs/findings

Front 1

CSF with elevated protein count, but normal WBC count

Back 1

Guillain-Barre syndrome

(high prot, normal WBC = albuminocutyologic dissociation)

Front 2

Xanthochromia seen in CSF

(yellowish appearance of CSF)

Back 2

Subarachnoid Hemorrhage

Front 3

Classic labs in Obstructive vs Restrictive Lung disease:
-TLC
-FEV1
-FVC

Back 3

Obstructive: ⬆TLC, ⬇FEV1, ⬇ FVC, ⬇ FEV1/FVC

Restrictive: ⬇TLC, ⬇FEV1, ⬇ FVC, Normal or⬆ FEV1/FVC

Front 4

Classic labs in DKA

Back 4

⬆ Glucose (300-800)

⬆ K+ or can be normal (acidosis causes K+ to shift out of cells, but total body K+ is actually decreased)

⬇ Na+ (why--b/c high Glucose spills into the urine, taking water and solutes, like Na+ & K+, along with it in a process known as OSMOTIC DIURESIS)

⬇ Phosphate

High Anion gap metabolic acidosis

(+) Serum & Urine Ketones

Front 5

Lab findings in Hemolytic anemia

Back 5

⬇ serum haptoglobin
⬆ bilirubin
⬆ LDH

Front 6

p-ANCA

Back 6

+ Crohn's dz
+ Allergic granulomatosis with polyangiitis (Churg-Strauss syndrome)
+/- PAN (sometimes)
+/- Primary Sclerosing Cholangitis
+ pauci-immune Crescentic Glomerulonephritis (RPGN)

Front 7

c-ANCA

Back 7

-Granulomatosis with polyangiitis (Wegener's)

Front 8

What are the abnormal values for a 2-hour glucose tolerance test

Back 8

2-hour glucose tolerance test:

> 140 = Insulin resistance

>200 = Diabetes

Front 9

Thyroid cancer than histopathologically demonstrates invasion of the capsule and blood vessels

Back 9

Follicular thyroid cancer....this invasion of capsule and blood vessels is required for differentiating between follicular cancers and follicular adenomas

Follicular cancers have an early hematogenous spread to the lung, brain, and bone.

Front 10

Hurthle cells

Back 10

are seen in both papillary and follicular thyroid cancer, so can't be used to differentiate them

Front 11

Bone scan with increased uptake in several spots in patient with hip pain for several months

Back 11

Paget's disease of bone

labs will also show an increased alkaline phosphatase

Front 12

Cutoff number for having proteinuria to qualify you for preeclampsia: _____/24 hr

Back 12

≥ 300 milligrams / 24 hr for mild preeclampsia
(i.e. ≥ 0.3 grams / 24 hr)

for severe preeclampsia it's ≥ 5,000 milligrams / 24hr (5 grams)

so if 24 hour protein is 1 gram, thats equal to 1,000 milligrams, so she definitely has preeclampsia!!!!

Front 13

A positive pronator drift test indicates:

Back 13

Upper motor neuron lesion

UMN's cause a weakness in supination that results in the pronator muscles becoming dominant...so when they close their eyes and extend their arms with palm up, the affected arm will tend to pronate)

Front 14

Abnormal Romberg (keeping balance with eyes closed) test indicates:

Back 14

Impaired Propioception

Front 15

Lab findings in AntiPhospholipid Antibody syndrome ("Lupus anticoagulant")

Back 15

⬆ or normal PTT
⬆ or normal D-dimer

Normal Bleeding time, platelet count, and vWF

The longer PTT is just due to this IgG or IgM binding the phospholipids used in the laboratory assay--so strictly a lab artifact...

Makes the patient hypercoaguable...in its with Lupus and VTE, APA syndrome must be suspected.
