Q

Liver

A
  • Produces bile acids for digestion
  • Processes medications, ETOH, and toxins (most important)
  • Stores vitamins A, B12, D and ferritin
  • Aids in carbohydrate metabolism, blood plasma proteins, protein metabolism
  • Aging causes the liver to have less activity R/T decrease in number of liver cells and liver enzyme activity -> that causes slower or worse processing of medications, ETOH, and toxins; less bile acid for digestion; slower/worse metabolism of carbs and proteins

Q

Abdominal Assessment - Inspection

A
  • Inspect mouth and skin of abdomen for color, lesions, striae, scars, shape and contour

Abnormal findings:
- Teeth damage, bleeding, lesions on the mouth -> can indicate poor nutrition or oral cancer
- Bulging masses on abdomen -> can indicate tumors or hernias
- Bulging, PULSING, masses on abdomen -> can indicate an aortic aneurysm. DO NOT TOUCH, GET DOC QUICKLY
- YELLOW SKIN (jaundice) -> LIVER DISEASE/DAMAGE
- BLUE/PURPLE COLORING AROUND UMBILICUS (Cullen’s sign) -> intraabdominal bleeding

Q

Abdominal Assessment - Auscultate

A
  • Listen to all 4 quadrants
  • Listen for several minutes before concluding “absent” bowel sounds
  • Auscultate prior to percussion and palpation because that can impact bowel sounds, make them more active than they would otherwise be

Abnormal Findings:
- Hypoactive sounds: caused by opioids, anesthetics, anticholinergic meds, constipation
- Absent sounds: BIG PROBLEM. Indicate ileus or bowel obstruction
- Hyperactive sounds: caused by cholinergic medications, inflammatory bowel disorders

Q

Abdominal Assessment - Palpation

A
  • Palpate LIGHTLY
  • Note any masses, tenderness, pain (do not palpate any pulsing masses)
  • Deep palpation and hooking techniques is used to measure patient’s liver for hepatomegaly (DONE BY THE PROVIDER)

ABNORMAL FINDINGS:
-spleen should not be palpable. If it is, it will be in the LUQ*
-Liver shouldn’t be palpable on light palpation- if it is, it will extend past ribs on RUQ, RLQ
- Mass: can be a tumor, aneurysm, or hernia
- Right abdomen: pain, guarding, or peritonitis

Q

Diagnostics / Barium Studies

A
  • X- rays combined with barium, which is radiopaque
  • Taking multiple x-rays allows us to watch the path of the barium through GI tract. *we can note any structural issues throughout (strictures of esophagus, ulceration in stomach, obstructions, polyps)
  • We can also note the speed of movement in the GI tract
    *Barium is a dry, white, chalky powder that is mixed with water

Q

Diagnostics / CT Scans

A

-CTs with contrast use an iodine-based contrast medium *Contrast medium provides better visualization of the area
- Make sure you ask about IODINE, SEAFOOD & SHELLFISH because of potential cross-reactivity
*BUT there is not a high percentage of issues with iodine allergies.

Q

Diagnostic / Endoscopy

A
  • Putting the tube with a camera and equipment up/down the GI tract to visualize the area and do procedures
  • Complications include: risk of perforation
    *S&S of perforation: VS changes to HR and BP related to potential bleeding, high temp related to peritonitis, OBVIOUS RED BLOOD IN STOOLS, TARRU BLACK STOOLS
  • Endoscopic Retrograde Cholangiopancreatograpy (ERCP) visualizes the pancreatic and bile ducts. CAN CAUSE PANCREATITIS IN ADDITION TO RISKS OF PERFORATION

Q

Stomatitis

A
  • Irritation and inflammation of the oral cavity
  • Associated with chemotherapy and radiation for cancer *Can be caused by viral, bacterial, or fungal infections **Can be caused by irritants like alcohol, tobacco, alcohol containing mouthwash
  • Presents as ulcerations and inflammation of the oral cavity
  • Causes problems with nutrition and fluid status
  • Nursing management: monitor I&O, weight, fluid & nutrition status, meds as ordered, keep lips and mouth moist, aspiration precautions if lidocaine is being used: raise head of bed, high protein food choices while discouraging salty, spicy, acidic, sharp-edged foods, mouth care after meals, no alcohol mouth wash, remove dentures, saline mouth rinse q4 hrs, high protein foods, avoid acidic spicy foods.

*PRIMARY: painful ulcers, herpes simplex, and traumatic ulcers
*SECONDARY: Viral, bacterial, or fungal

Q

Hiatal Hernias

A
  • Part of the stomach herniates above the diaphragm
  • 95%= sliding type, 5%= rolling type
  • Risk Factors: obesity, pregnancy, tobacco, western diet (low in fiber)
    -S&S: heartburn, regurgitation, dysphagia, chest pain, belching, GERD; can have very little symptoms
  • Can eventually cause Barrett’s Esophagus- precancerous state
  • Obesity can cause an increase of abdominal pressure
    MANAGEMENT:
    -Medications: Proton Pump Inhibitors (PPIs), Histamine receptor antagonists (H2 blockers), antacid tablets
  • Lifestyle changes: avoid caffeine, spicy food, fatty food, ETOH, smoking, NSAIDs and aspirin *Don’t lie down until >2hrs. past meals and don’t snack at night **Reduce weight (CANNOT BURP)
  • Surgical treatment: Nissen Fundoplication

*Portion of stomach protrudes upward through esophageal hiatus
*Type 1- widened and enlarge just above
*Type 2- pouch to the side

17
Q

Gastroesophageal Reflux Disease (GERD)

A
  • Retrograde “reversed” flow of GI contents into esophagus
    *I.E. stomach acid and digestive juices leave stomach and visit the esophagus
  • Results: inflammation of the esophagus
  • Risk Factors: hiatal hernia, obesity, ETOH, pregnancy, big meals
  • S&S: heartburn, regurgitation, dysphagia, chest pain, belching ** More sever: aspiration pneumonia, hemorrhage
  • Eventually can cause Barrett’s Esophagus - precancerous state
    ~Management:
  • Medications: PPI’s, H2 blockers, antacid tablets
  • Lifestyle changes: avoid caffeine, spicy food, fatty food, ETOH, smoking, NSAIDS, aspirin *Do not lie down until >2hrs. past meals and don’t snack at night, reduce weight
  • Surgical treatment: Nissen Fundoplication
18
Q

Aspiration Pneumonia

A
  • food or liquid is breathed into the airways or lungs, instead of being swallowed
  • Aspiration pneumonia is why we do GI prophylaxis with PPIs or H2 blockers for post-surgical, ICU, and burn patients
19
Q

Oral & Esophageal Cancer

A
  • Development of cancer on the lips, mouth, oral cavity, or esophagus
  • Risk Factors: smoking, ETOH, HPV, poor oral hygiene
  • S&S: few early symptoms -> severe: bleeding, ulcerated areas, dysphagia, mouth odor, weight loss, swallowing issues

MANAGEMENT: treated like any other cancers. Due to location, big risk for AIRWAY COMPROMISE and nutritional issues.

20
Q

Oral & Esophageal Trauma

A
  • Significant sores to the face, mouth, or esophagus
  • Risk Factors: GETTING OLDER AND FALLING DOWN, MVAs, altercations, etc
  • S&S depends on location/severity of injury: lots of bleeding because the areas are highly vascularized
  • Biggest concerns: AIRWAY & BREATHING; stridor, increased RR, SoB, decreased o2 stats, change in LoC

MANAGEMENT:
- Surgical stabilization of broken bones
- Possible for jaw to be wired shut; WIRE CUTTERS W/ PATIENT AT ALL TIMES in case of emergency

21
Q

Tracheostomy

A
  • May be necessary due to oral or esophageal trauma or cancer
    PRIORITY INTERVENTIONS:
  • KEEP HoB ELEVATED, never below 30 degrees
  • Suction frequently
  • Call light with patient
  • Humidify the o2 the patient is receiving
  • Keep emergency tracheostomy kit in room -> losing a fresh trach is a medical emergency - get help immediately
22
Q

GI Prophylaxis

A
  • Surgery, ICU stays, burns, long-term illnesses case stress on patients which can increase stomach acid production and lead to GERD, ulcers, and even aspiration pneumonia
  • To combat this, we provide GI prophylaxis - a PPI like Prilosec, Nexium or Protonix to reduce stomach acid production during hospitalizations
23
Q

CH 57 Terms

A
24
Q

Gastritis

A
  • Acute Gastritis: hours- days of gastric inflammation
    *Causes: irritating foods, ETOH, NSAIDS. aspirin overuse, endotoxins from bacteria, body trauma. like burns or surgery
  • Chronic Gastritis: prolonged, persistent, or intermittent gastric inflammation
    *Causes: H. PYLORI INFECTION, autoimmune gastritis, atrophic gastritis

-S&S: EPIGASTRIC PAIN, N/V/D, weight loss, decreased appetite, ->Sever cases: GI bleeding, dehydration

Treatment: Relieve the symptoms, remove the cause
- GI rest then slowly reintroduce foods
- Medications like PPIs, H2 Blockers, antacids, carafate
- Treat H. Pylori with ABX

25
Q

Gastroenteritis

A
  • Self-limiting illness of the stomach and small intestine “classic stomach flu”
  • Causes: infectious agents/viruses, or bacteria (*salmonella, shigella, camplyobacter, E.Coli, Clostridium
  • S&S: N/V/D, anorexia, abdominal pain, abdominal distention and in severe cases dehydration

~Treatment: relive the symptoms, remove the cause, treat present dehydration
**GI rest then slowly reintroduce foods, medications (PPIs, H2 blockers, antacids, carafate), IV fluids- oral rehydration

26
Q

Peptic Ulcer Disease (PUD)
- Ulcerations of the GI tract

A
  • Gastric (20%), triggered or worsened by eating, alleviated by fasting
  • Duodenal (80%), triggered or worsened by fasting, alleviated by eating
    -Most common cause is H. Pylori -Other causes: NSAIDS, ETOH, smoking, aspirin
    -S&S: EPIGASTRIC PAIN that may radiate to R shoulder or back. Pain noted lasts weeks or months. Many things cause epigastric pain (factors into diagnostics, reoccurrence becomes part of out diagnostic criteria)
    ~Treatment: symptom management, ulcer healing, prevention of ulcer reoccurrence
  • Treat H. Pylori with ABX
  • Medications: PPIs, H2 blockers, antacids, Carafate, CYTOTEC (causes abortions)
  • Diet/lifestyle changes: smaller meals, avoid irritants like ETOH, smoking, caffeine, spicy/acidic foods
  • ## If untreated: GI bleeds that may require surgical intervention
27
Q

Gastric Cancer

A

-Cancer of the GI tract
- S&S: asymptomatic at 1st, symptoms will be nonspecific and vague (indigestion, anorexia, weight loss, vague epigastric pain, vomiting,
** an abnormal mass may be noted when/if tumors get large enough
-Treatment: remove cancer surgically if possible, radiation and chemotherapy to kill remaining cancerous cells. Manage symptoms while doing so
*Surgery to resect the stomach/GI, issues include absorption of nutrients - issues like iron-deficiency anemia, Vitamin B-12 deficiency anemia, poor nutrition status shown by low levels of albumin and pre-albumin

28
Q

MEDICATION REVIEW

A

-PPIs: Omeprazole (Prilosec), Esomeprazole (Nexium), Pantoprazole (Protonix) = blocks acid production in the stomach ( takes hours to days to reach full effect)
-H2 blockers: Famotidine (Pepcid), Cimetidine (Tagamet), Nizatidine (Axid) = blocks acid production in the stomach (works faster bot does not last long)
-Carafate (Sucralfate): forms a physical barrier or coating over the stomach to protect it from acid
-Misoprostol (Cytotec): reduces gastric acid production & physically protects the stomach but…
-NSAIDS, aspirin: not great for stomach, damage stomach lining.
-Antacids: neutralize stomach acid via a chemical reaction (antacids are basic, so neutralize the acids in stomach)
