signs of symptoms: GNAWING epigastric pain

2

signs/symptoms of perforated ulcers:

severe epigastric pain

rigid boardlike abd

quiet bowel sounds

3

What are three causes of a perfed bowel?

peptic ulcer disease

ruptured diverticulum

appendicitis (rare)

4

This is tested by a urea breath test, can be present with duodenal or gastric ulcers

H. pylori

5

What is the step-wise approach for outpatient management of peptic ulcer disease?

1st line, everybody gets this: H2 blockers

-tidine

ranitidince (zantac) famotidine (pepcid)

2nd line: PPIs

-azole

lansoprazole (prevacid) omeprazole (prilosec) esomeprazole (nexmium)

6

What musosal protective agent is used for traveler's diarrhea and has direct action against H. pylori?

bismuth subsalicylate (peptobismal)

7

What mucosal protective agent is used for NSAID induced ulcer prophylaxis and it therefore given to patients with RA who take chronic NSAIDS?

Misopristol (cytotec)

8

H. pylori eradication therapy includes five possible 3 drug combinations.  What three combinations use 2 abx + PPI?

AOC

MOC

MOA

          A            *amoxicillin+omeprazole+clarithromycin

          O            *Metronidazole + omeprazole + clarithromycin

M  O  C            *Metronidazole + omeprazole + amoxicillin

O

A

9

H. pylori eradication therapy includes five possible 3 drug combinations. What are the two regimens that include 2 abx + 1 bismuth?

THE BMT BMTO is not as popular due to qid dosing

BMT: bismuth+metronidazole+tetracycline

 

BMTO: bismuth+metronidazole+tetracycline+omeprazole

10

If you suspect a bowel perf, what imaging would you order and what would it show?

upright or decubitus abd xray show in about 75% of cases

you would expect it to show free air under the abd

11

1)  When the normal tissue lining the esophagus changes to tissue that resembles the lining of the intestine.

2)  this is a serious complication of GERD.

3) this finding increases the risk of developing esophageal adenocarcinoma, which is a serious, potentially fatal cancer of the esophagus.

 

Barrett's esophagus

12

What are normal platelet count?

150-400

13

With hepatitis A, the blood and stool are infectious during the _______ week incubation period:

2-6 week incubation period

14

Hep B is transmitted through:

blood

sexual activity

mother-fetus

15

Which two types of hepatitis have a vaccine?

 A and B

16

Why do patients in the icteric phase have jaundice?

from unconjugated bilirubin

17

What is the Normal AST ALT lab values?

35-50

18

Your patients hepatitis serology shows Anti-HAV, IgM.  What does that mean?

anti-HAV means their body has produced an antibody for hepatitis A

 

IgM means iMMEDIATE or Miserable, they are actively infected

so 

they have active hep A infection

19

You patients hepatitis serology shows anti-HAV, IgG.  How do you interpret that?

recovered hepatitis A

(G=Gone)

20

In hepatitis serology, HBeAg signifies what?

It indicates viral replication and infectivity of Hep B.

 

It means they can transmit hep B

21

If your patient's hepatitis serology shows HBsAg, HBeAg, Anti-HBc, IgM, what does that mean?

They have active transmittable hep B

HBeAg (antigen is the bad guy) = transmittable

IgM=miserable, iMediate

 

22

Your patients hepatitis serology shows: HBsAg, Anti-HBc, anti-HBe, IgM, IgG.  What is the diagnosis?

Chronic hep B

IgM and IgG

23

Your patients hepatitis serology shows: Anti-HBc, Anti-HBsAg.

What is the diagnosis?

recovered Hep B

anti- the body has developed antibodies

24

Your patients hepatitis serology shows: 

anti-HCV, HCV RNA

What are the TWO possible diagnoses and how would you further differentiate the diagnosis?

acute or chronic Hep C

 

PCR is used to differentiate prior exposure (chronic hep C) from current viremia (acute hep C)

25

Diverticulitis is inflammation of diverticula with abscess formation.  What are two physical findings?

low grade fever

LLQ abd tenderness to palpation

 

 

26

A female patient with a low fiber diet is diagnosed with diverticulitis.  You admit her to the hospital.  What is the diet order for a patient with diverticulitis?

A patient with diverticulitis should be made NPO

27

All patients diagnosed with diverticulitis should have plain abdominal films done to look for evidence of:

free air under the diaghragm which would indicate bowel perforation

28

You have a fat fair forty and female patient with a positive Murphy's sign and c/o RUQ abd pain after eating fatty foods.  You suspect what?

29

What labs are typically elevated in cholecystitis?

ALT 

AST

LDH

alk phos

*possible amylase

30

What is the most common cause of pancreatitis?

gallbladder disease/cholecystitis

31

What are three common causes of pancreatitis?

cholecystitis

hyperlipidemia

HEAVY alcohol use

If a patient had a paralytic ileus, what would their bowel sounds be?

absent bowel sounds
