Flashcards in UWorld_7.28 Deck (30):
1

Labs to check before starting Li

creatinine

2

Peripheral smear in lead poisoning

basophilic stippling

3

Risk factor for clear cell adenocarcinoma of cervix/vagina

DES exposure in utero

4

DES exposure in utero consequences

-clear cell adenocarcinoma of cervix/vagina
-structural anomalies of reproductive tract: hooded cervix, T-shaped uterus, small uterine cavity, vaginal septae
-pregnancy problems
-infertility

5

Amox-clav coverage

-gram +
-gram -
-anearobes

6

Abx for human bite

amox-clav; also for dog bites

7

First line tx of idiopathic intracranial HTN

acetazolamide (inhibits choriod plexus carbonic anhydrase) +/- furosemide

8

Evaluation of renal colic in pregnant patients

-US = first line
-low dose CT urography can be considered in 2nd/3rd trimesters

9

Management of kidney stones in pregnancy

1. conservative measures
2. uterocsopy or nephrostomy if refractory
3. shockwave lithotripsy is contraindicated

10

HCM inheritance

autosomal dominant

11

Dx of carpal tunnel syndrome

nerve conduction study

12

Main cause of acute interstitial nephritis

drugs: PCNs, TMP-SMX, cephalosporins, NSAIDs

13

Presentation of acute interstitial nephritis

-maculopapular rash
-fever
-new drug exposure
-+/- arthralgias
-AKI
-pyuria, hematuria, WBC casts
-eosinophils @ urine

14

Best long-term tx of graves

radioactive iodine therapy

15

Anion gap =

Na - (Cl + HCO3) > 16

16

DDx of AGMA w/elevated serum lactic acid

lactic acidosis/hypoperfusion

17

DDx of AGMA w/hx of drug ingestion

-salicylates (early resp. alkalosis)
-isoniazid
-iron

18

DDx of AGMA w/osmolal gap

-ethylene glycol ==> urinary calcium oxalate crystals (rectangular, envelope-shaped)
-methanol ==> blindness
-propylene glycol

19

AGMA + urine calcium oxalate crystals ==> dx?

ethylene glycol ingestion

20

AGMA + blindness ==> dx?

methanol ingestion

21

Osmolal gap calculation

OG = measured - calculated (normal

22

Patellofemoral pain presentation

-young female athletes
-subacute pain; increased w/squatting, running, stairs, prolonged sitting
- + patellofemoral compression test

23

Patellar tendonitis presentation

-athletes ("jumpers knee")
-episodic
-tenderness @ inferior patella

24

CHF impact on renal physiology

-CHF ==> decreased effective arterial volume ==> activation of RAAS ==> increased AgII ==> vasoconstriction of efferent renal arterioles (in order to maintain adequate intraglomerular pressure/GFR)

25

Characteristics of leukemoid reaction

-response to severe infection ==> WBCs > 50,000
-high alk phos
-greater metamyelocytes vs. myelocytes (Myelocytes > metamyelocytes @ CML)
-no absolute basophilia (vs. + @ CML)

26

Milk-alkali pathophysiology and sx

-excess intake of Ca & absorbable alkali
-renal vasoconstriction ==> decreased GFR
-renal loss of sodium/H2O; reabsorption of HCO3

-N/V, constipation
-polyuria, polydipsia
-neuropsych sx

27

Lab findings in milk-alkali syndrome

-hypercalcemia
-metabolic alkalosis
-AKI
-suppressed PTH

28

-isotonic saline + furosemide

29

Vitamin A toxicity presentation

-abdominal pain
-dry skin, H/A, blurred vision
-hypercalcemia

30
