A

•Meclizine (Antivert)
•ondansetron (Zofran)
•Metoclopramide (Reglan)

26
Q

Nursing management of N/V problems

A

•medication (IV push reglan, zofran for n/v)
•nutrition (oral is the best way to rehydrate a Pt if able, then IV fluid)
•treat underlying cause
•Alternative Tx (Elevated rest to avoid GERD, BRAT diet, no spicy food, ginger OIL & peppermint OIL helps with upset, acupuncture)
•gerontological considerations (higher risk for dehydration/F&E imbalance)

  • be careful in renal Pt’s with sports drinks they can’t filter the electrolytes and end up with an imbalance)
    •BRAT = Bananas, rice, applesauce, toast
27
Q

What is GERD?

A

Gastroesophageal Reflux Disease:
GERD/heartburn
■Chronic condition
■Usually due to a weak or damaged LES (lower esophageal sphincter)
■causes (meds/NSAIDs, spicy/fatty food, caffeine/alcohol, aging/sphincter weakness, nicotine, obese Pt’s, overeating, laying down after meals)
■Dx: (try meds 1st then if they don’t work do these)
Upper GI endoscopy, barium swallow, ph monitoring, gastric emptying study.

28
Q

Manifestations of GERD?

A

■Persistent mild symptoms or mod-severe
■Heartburn is the most common symptom (mild epigastric pain)
■Chest pain (angina)
■Dyspepsia & regurgitation (pain centered in upper abdomen, big problem in the elderly because of delayed gastric emptying)
■Other symptoms:
abnormal pain/bloating, coughing, wheezing/dyspnea, sore throat/feeling of lump in your throat
■always do least-most invasive. Try meds before procedures

29
Q

Drug therapy for GERD (3 classes!)

A

•PPIs (1st line for esophagitis, prevents movement of hydrogen ions (protons) out of the parietal cell into the stomach, thereby blocks gastric acid secretion.)
•protonix (PPI)

•Histamine (H2) Receptor Blockers: block the action of histamine on the H2 receptors to “decrease acid secretion.”
•Famotidine (Pepcid) take 30 mins before meals

Risks: osteoporosis, risk for possible c-diff

•Antacids: used with or without PPI’s/H2.
–Magnesium hydroxide (watch in renal Pt’s or with elevated mag level)
–Aluminum hydroxide
–Be cautious with elderly( kidney/liver problems, polypharmacy)
–Check interactions with other home meds**

30
Q

Nursing management of GERD

A

■Teach patient about diet and eating small frequent meals
■Tell patient not to lay down for 2-3 hours after eating
■Elevate HOB to sleep (promote gastric emptying)
■Medication education
■Caregiver education (they might do the shopping/cooking they need to know!)

31
Q

Surgical Therapy for GERD, complications?

A

■Antireflux surgery: to reduce reflux by enhancing integrity of the LES
–Nissan and Toupet fundoplication
■Complications: splenic injury, infection
■Linx Reflux Management System
■Endoscopic therapy: mucosal resection and ablation
*edema of mouth/esophagus after surgery is normal for days-month. If longer then call HCP

32
Q

What is a hiatal hernia?

A

Two types: sliding and paraesophageal (rolling- medical emergency)
■A herniation of part of the stomach into the esophagus through and opening (hiatus) in the diaphragm
■Common in older adults and more common in women
■Causes:
–structural changes
–factors increasing intraabdominal pressure (weightlifters, obesity, pregnancy, tumor, ascites)

33
Q

What are the different types of hiatal hernias?

A

■Sliding
■Paraoesophageal or rolling: Medical emergency tissue gets cut off from blood/oxygen supply and necrosis can happen

34
Q

Clinical manifestations of Hiatal Hernias? Diagnostics?

A

■Symptoms are similar to GERD

■complications: GERD, esophagitis, hemorrhage from erosion, stenosis, ulcerations of herniated part, strangulation of hernia, regurgitation with tracheal aspirations

Diagnostic Studies:
■Barium swallow
■Endoscopy

35
Q

Nursing management of Hiatal Hernias?

A

Also Similar to GERD- goal is to reduce intraabdominal pressure
■Surgical approaches (not tested on different ones)
■Gerontological Considerations: kyphosis, girdles, may develop before they know what’s going on because their symptoms are less noticeable)

36
Q

What medications create extra acidity and weakening of LES? test

A

•NSAIDs
•K+ (potassium)
•Antidepressants
•calcium channel blockers

37
Q

What is PUD? (Overview of slide!)

A

Peptic ulcer Disease: Characterized by erosion of the GI mucosa caused by digestive action of HCL acid and pepsin. Can be acute or chronic * (chronic can burn through esophageal wall)
■Gastric and duodenal present differently
–Gastric more common in women, 50-60 y.o., increased cancer risk, pain 1-2 hours after food. (Shorter time to get to irritated portion)

–Duodenal more common in men, 34-45 y.o., no increased cancer risk, pain 2-5 hours after (longer time to get to this point for s/s)

38
Q

What are the causes of Peptic Ulcer Disease?

A

■Helicobacter Pylori (H.pylori)
-however just because a Pt has the bacteria doesn’t mean they automatically also have PUD
-Transmitted possibly by fecal-oral or oral-oral from family
■Medication induced (NSAIDs)
■Lifestyle (alcohol, caffeine, smoking, stress, spicy food)
■Comorbidities(mainly for duodenal ulcers): COPD, cirrhosis, pancreatitis, hyperparathyroidism, CKD

39
Q

What are the clinical manifestations of PUD?

A

■Gastric Ulcers: pain 1-2 hrs after eating (geriatric risk “silent PUD”)
–Sometimes goes unnoticed until ulcer has eroded through mucosa and pain is present with all ingestion.
■Duodenal Ulcers: 2-5hrs after eating
–Described as “burning” or “cramping”.
■Both types may cause bloating, n&V, and early fullness

40
Q

What are the diagnostic studies for PUD?

A

■Barium swallow
■Endoscopy (most accurate/can take biopsy /test secretions for H.pylori)(looks at stomach, esophagus, duodenum)
■Biopsy of mucosa to test for urease (Urea is a biproduct of H.pylori)
■Lab tests (elevated gastrin, CBC:H&H/WBC, liver enzyme:ast/alt, kidney panel/amylase/Lipase, stool study dark color)

41
Q

Drug therapy for PUD? Test

A

•Reduce secretions AND tx H.pylori
•always treat the cause (h.pylori is causing the ulcers!)
•2 rounds of 14 day regimen of triple med therapy :
-amoxicillin
-clarithromycin (biaxin)
-metronidazole (Flagyl)
-tetracycline
-PPI
•H2 receptor blockers, antacids, misoprostol, tricyclic antidepressants

42
Q

Complications of PUD: Hemorrhage

A

Most common complication
■S&S:

1. Increased HR/BP
2. BP drop d/t hypovolemia
3. Weak, thready pulse, increased RR

43
Q

Complications of PUD: Perforation (hole)

A

Highest risk with large penetrating duodenal ulcers
■S&S: sudden severe upper abdominal pain that quickly spreads throughout abdomen
–Radiates to back and shoulders
–Abdomen is rigid and board-like (painful)
–Bowel sounds absent (sympathetic response)
-antacids will no longer help, problem is too advanced. Bile, stomach acid, food, saliva is all leaking out into peritoneal cavity**

44
Q

Complications of PUD: Gastric outlet Obstruction

A

medical emergency

■Causes from acute or chronic issues
■S&S: edema, pylo spasms, pain relieved by burping or vomiting, constipation
■Tx: decompress stomach (NG tube) for days
–Correct F&E imbalances (K+ low)
–Balloon dilation/stent/scar tissue removal
–Pain management
–Possible PPI (block secretions) or h2 receptor blocker

45
Q

Nutritional Therapy for PUD?

A

■No caffeine
■No alcohol
■**Eliminate foods that cause symptoms! **(specific for each Pt)
■Hot and spicy foods (may irritate some but not others)
■Carbonated drinks
■Acidy foods such as tomatoes
■Meat extract (broth)
■Supplement with vitamin B-12

46
Q

Surgical Therapy for PUD?

A

■Try meds and lifestyle changes first surgery is last resort **
■Vagotomy: cutting a branch of the vagus nerve
■Pyloroplasty: surgical incision into the pyloris or sphincter where stomach empties to duodenum
■Same post-op tx for perioperative
NPO, (to decrease gastric secretions)
PPI (protonix)
Slowly increase food (ice chips, then clear liquid diet etc)

47
Q

Nursing considerations for PUD?

A

■Overall goals:
–Adhere to the prescribed therapeutic regimen (antibiotic regimen)
–Reduce pain
–Prevent complications
–Nutritional therapy (teach caregiver!)
–Lifestyle change education
■Labs (H&H- bleeding important for post-op. WBC-infection)
■Tx complications: h.pylori, medications (specifically NSAIDs)

48
Q

What is dumping syndrome?

A

Complication after surgical removal of a large part of the stomach and pyloric sphincter
■Symptoms: Generalized weakness, dizziness, diaphoresis, tachycardia, abdominal cramping, self-limiting, epigastric fullness
-occurs 15 min after eating

■Tell patient to rest after eating, may reduce the incidence

49
