Module 5 Upper GI Flashcards
How long does the GI tract extend? What are the main functions?
•30 feet
•The main function is to supply nutrients to body cells by:
–Ingestion
-digestion
-absorption
-elimination
How much cardiac output does the G.I. tract and accessory organs receive during rest and during eating?
GI tract and accessory organs receive 25-30% of cardiac output at rest, and 35% or more after eating.
What changes occur related to the G.I. system as people age?
•LES delayed emptying /muscle weakness (sphincter problems/Gerd)
• slower peristalsis (constipation)
•slowed metabolism with food & medication
• decreased hunger and thirst
• incontinence (dysfunction of anal sphincter)
• difficulty chewing (no teeth or dentures)
• lose taste buds or sense of smell
• can’t shop or cook for themselves
• liver enzymes change
What subjective data can you gather from a patient about the G.I. system?
•PMH (pertinent history how it’s affecting them (constipation, diarrhea)
•Medications (are the meds they’re on causing these problems? Polypharmacy?) 
•Health Management (Active? Fiber? Stool softeners? Past procedures? Lactose intolerance? Gerd with spicy food? Have they traveled lately?- stomach bug)
What objective data can you gather from a patient about the G.I. system?
Physical exam:
•inspect
•auscultate (normal: 5-35 bowel sounds a minute, soft, non-tender)
• palpation (have pt as flat as tolerable, empty bladder, assess for hemorrhoids and anal sphincter tone)
What would be considered abnormal findings during your assessment of the G.I. system?
•Firm tender abdomen
•discoloration, lesions, scars, masses, not symmetrical
• assessed for hemorrhoids, bleeding, assessed for anal sphincter tone
What is the correct way to auscultate the patient’s abdomen?
RLQ, RUQ, LUQ, LLQ
What are the 8 Diagnostic studies we can perform for upper GI problems?
■EGD
■Ultrasound
■CT Scan
■MRI
■ERCP- Endoscopic retrograde cholangiopancreatography)
■Upper GI/Barium Swallow
■Capsule endoscopy
■Biopsy
Which diagnostic would be run 1st, 2nd?
- Ultrasound (size, condition, and configuration of organs)
- MRI (can see lesions, where the bleed is, cancers, may or may not use contrast)
What is a Barium Swallow?
The Pt will be NPO, given contrast and then x-rays are taken
What is a ERCP?
Endoscopic retrograde cholangiopancreatography
Fiber optic camera scope sent into the duodenum and can look/place a stent into the bile duct of liver/pancreas
What is a capsule endoscopy?
The Pt will swallow and digest a capsule that has a camera in it. Through it’s way out of the body it can take up to 50,000 pictures to try to determine where to problem is in the GI tract.
What is in a CBC?
•RBC
• H & H (levels important for bleed!)
•WBC (levels important for infection!)
•platelets
What is in a metabolic panel?
•Glucose
•electrolytes (levels important to see absorption)
• Albumin (levels important for nutritional status. Keeps fluid in the bloodstream instead of tissues)
•BUN/ Creatinine (levels important for kidney function & hydration status)
What are liver function tests? (LFTs)
AST (1-36)
ALT (12-78)
What is Bilirubin?
A waste product to be excreted.
It’s A molecule formed from the breakdown of RBC. Bilirubin has a yellow pigment and when it builds up, Pt’s present jaundice (yellow)
What are the two pancreatic studies?
Amylase
Lipase
What are clotting factors studies?
Pt
PTT
Vitamin K
All help with coagulation of blood to form clots to stop a bleed.
What to triglycerides look at?
Cholesterol levels
What is an occult study and how
Is it done?
A stool study is a diagnostic that determines if there is blood in the stool sample.
A Dr. will perform a digital anal exam and do a stool smear on a specialized paper that reacts when blood in the stool is confirmed.
When the sympathetic/parasympathetic systems of the GI get activated, What are the S/S of gastroenteritis?
•infection*
•MI (back pain, nausea)*
•motion sickness*
•migraines
•chemo/medications
•acid reflux
•pregnancy
•food poisoning
•stress/fear
•Alcohol
Can all cause N/V
Where is the control for vomiting?
Located in the medulla portion of the brain activates the signal to throw up.
