Why do you drink cranberry juice to treat UTIs?
to decrease the ability of bacteria to adhere to the epithelial cells lining the urinary tract.
What is the purpose of ureteral stents?
Small tube placed in ureter.
Dilates the ureter and enlarges the passageway for the stone or stone fragments.
Prevents the passaging stone from coming in contact with the ureteral mucosa and so it reduces pain, bleeding and infection risk.
Foley catheter is places to facilitate passage of stone through urethra.

A catheter you can do yourself. Insert a a thin, hollow tube through the urethra into the bladder and allow the urine to drain out. Not permanent.
Benign Prostate Hypertrophy BPH
With aging. The prostrate gland enlarges and extends upward into the bladder and inward, causing bladder obstruction. The detrusor muscle thickens and cannot contract effectively.
Prostate will be enlarged, non tender.
Patient will have increased statis or acute or chronic retention.

Side effects: decreased libido and ED
What is TURP and what are the disadvantages?
Transurethral resection of the prostate. Closed surgery (using the bodies openings)
enlarged portion of the prostate is removed endoscopically.
Disadvantage: since only a few pieces are removed, remaining tissue may continue to grow and cause urinary obstruction, requiring additional TURPs.
High risk for hemorrhage and severe bleeding
Tell me about prostate cancer.
Most common type of cancer. Slow growing and metastasizes in nearby lymph nodes, bones, lungs and liver.

Painful uterine cramping with spasmodic lower abdominal. Pain often travels to lower back and thighs.
What causes dysmenorrhea?
increased production and release of uterine prostaglandins which cause spasms in myometrium, which constrict uterine blood flow, resulting in ischemia and pain.
What is Dysfunctional Uterine Bleeding and when does it occur?
Bleeding in excessive amount- more than 21 mL or more than 21 days.
Occurs the the beginning or end of productive years.
a hormone imbalance because ovaries fail to ovulate. This decreases progesterone production which is needed to mature the uterine lining and prevent growth. Without progesterone, the estrogen stimulation causes the endometrium past its hormonal support, causing uterine bleeding.
Management for DUB
- Estrogen therapy
- Hormonal contraceptives
- Progestin Pills
- IUD (nuvaring)
Endometrial Ablation-removal of a buildup of endometrial lining through a laser, roller ball or balloon.
Downward displacement of the uterus through the pelvic floor.

What is a peptic ulcer?
a mucosal lesion of the stomach or duodenum. Results when mucosal defenses become impaired and can no longer protect the epithelium from effects of acid and pepsin.
What happens to form a gastric ulcer and what plays an important role in the formation?
Acid, pepsin and H. Pylori
When the pyloric sphincter dysfunctions, the bile backs up into the stomach. This reflux breaks the integrity of the mucosal barrier and produced hydrogen ion back-diffsion which results in mucosal inflammation. Toxic agents and bile destroy the membrane of gastric mucosa.
What is a duodenal ulcer?
Most occur in upper part of abdomen.
Deep, sharply demarcated lesions that penetrate into the muscle layer.
pH levels are low.

What is the difference between mild and severe inflammation in ulcerative colitis?
Mild- intestinal mucose is hyperemic (increased blood flow), edematous and reddened.
Severe- lining can bleed and small erosions, or ulcers occur. Abscesses can form and result in tissue necrosis (cell death).

Total Colectomy with Continent (Kock's) Ileostomy- internal ileal reservoir, intra-abdominal pouch, monitor drainage
Total Colectomy with Ileoanal Anastomosis (J-pouch) - J-pouch is an ileoanal reservoir that spares the renal sphincter and the need for an ostomy
Chrohn's disease. What is it and what does it result in?
- an inflammatory disease in the small intestine (most often), colon or both.
- Can affect GI tract from mouth to anus but usually the terminal ileum.
- causes a thickened bowel wall.
- Strictures and deep ulcerations (cobblestone) appearance which predispose the patient to fistulas. Result is severe diarrhea and malabsorption of nutrients.
- Cancer of the bowel may develop after the disease has been present for 15-20 years.
Surgical Management for Chrohn's disease
MIS via Laparoscopy
Small bowel resection and ileocecal resections
Stricturoplasty which increases the bowel diameter.
What is a mechanical obstruction?
the bowel is physically blocked by problems outside the intestine (adhesions) in the bowel wall (crohn's disease), or in the intestinal lumen (tumors)
The intestinal contents accumulate at and above the area of obstruction. Distention results from the intestines inability to absorb the contents and move them down the intestinal tract. Peristalsis increases to try to move the contents forward. This increase stimulates more secretions which leads to additional distention.
What is a non-mechanical obstruction?
also known as paralytic ileus. does not involve a physical obstruction in or outside the intestine. Peristalsis is decreased or absent as a result of neuromuscular disturbance, resulting in a slowing of the movement or a backup of intestinal contents.
most common cause is the handling of intestines during abdominal surgery.
What are some problems that occur from intestinal obstructions?
- Reduced circulatory blood volume (hypovolemia)
- electrolyte imbalances
- Obstruction high in the small intestine
- causes a loss of gastric hydrochloride
- makes more basic
- Obstruction at the end of the small intestine and lower in the intestinal tract that causes a loss of alkaline fluids.
- makes more acidic
- bacteria that lies stagnant in the obstructed intestine.
- closed-loop obstruction (blockage in two areas).
- obstruction with compromised blood flow.
twisting of the intestine
telescoping of a segment of the intestine within itself
Nonsurgical management for intestinal obstructions.
- NG tube- to decompress the bowel by draining fluid and air.
- Question about passage of flatus.
- Flatus or stool means that peristalsis has returned.
- IV fluid replacement and management.
Surgical Management for Intestinal Obstruction
Exploratory laparotomy- a surgical opening of the abdominal cavity to investigate the cause of the obstruction. If adhesions are found, they are lysed (cut and released)
Rapid emptying of food contents into the small intestine, which shifts fluid into the gut causing abdominal distention. Symptoms include vertigo, tachycardia, syncope, sweating, pallor, palpitations, desire to lay down.
Management for dumping syndrome
- nutrition changes that include decreasing the amount of food taken at one time, and eliminating liquids ingested with meals.
- Eat a high-protein, high-fat, low to moderate carb diet.
- are sacs resulting from herniation of esophageal mucosa. Patients report dysphagia, regurgitation, nocturnal cough, halitosis (bad breath).
- Diagnosed with EGD.
- Major interventions are nutrition therapy and positioning. Avoid vigorous exercise after meals. Elevate HOB. No restrictive clothing. NO frequent bending.
Surgical Management for esophageal diverticula
aimed at removing diverticula. NPO for several days to promote healing.
IV fluid for pain-relief measures
monitor for bleeding or perforation.
NG tube is placed during surgery for decompression and is not irrigated or repositioned unless requested by surgeon.

- are a life-threatening medical emergency.
Greater than the normal amount of fat in the feces
Protrusion of the stomach through the esophageal hiatus into the diaphragm.
What are the two types of hiatal hernias?
Sliding- most common. stomach slides upward through the esophageal hiatus into the chest, usually as a result of a weakened diaphragm. Major concern is the development of esophageal reflux.
Paraesophageal (rolling) reflux- fundus rolls into the thorax beside the esophagus. Reflux is not usually present. High risk for volvulus, obstruction and strangulation.
Surgical management of hiatal hernias
Laproscopic Nissen Fundoplication- surgeon wraps a portion of the stomach fundus around the distal esophagus to anchor and reinforce the LES
preop care for a patient with hiatal hernias
teach PT about chest tubes

splint during coughing.
Have a NG tube to prevent the fundoplication wrap from becoming too tight around the esophagus.
Common complication of LNF (Laprascopic Nissen Fundoplication)
Gas bloat syndrome, where the patients are unable to voluntarily burp. Avoid carbonated beverages and eating gas-producing foods, chewing gum and drinking through a straw.
Other complication is aerophagia (air swallowing) from attempting to reverse or clear acid reflux. Frequent position changes and ambulation.
Total Proctocolectomy with a permanent ileostomy
Removal of colon, rectum and anus.
for patients undergoing a colectomy.
bring the ileum out through the abdominal wall and forms a stoma.
- After surgery, output is a lose, dark green liquid that may contain blood. Ileostomy adaptation will occur.
- Small intestine will begin to perform previous colon functions, like absorption of water and sodium.
- Effluent fluid material will have little or sweet odor. Any foul or unpleasant odor may be a sign of blockage or infection.
ileostomy (location, care, and what you would expect)
loop of the ilieum is placed through the abdominal wall for drainage of fecal material into a pouching system worn on the abdomen
care: empty when 1/3 to 1/2 full, change entire pouch every 3-7 days

what is decompensated cirrhosis?
the livers function is impaired with obvious manifestations of liver failure
Complications of cirrhosis:
increased in pressure within the portal vein from increased resistance or obstruction of blood flow. blood flows back to spleen, veins in esophagus, stomach, intestines, abdomen, and rectum become dilated.
free fluid in peritoneal cavity from increased hydrostatic pressure from portal hypertension.
results from fluid shift into abdomen.
esophageal veins become distended from increased pressure. Emergency!
production of bile in liver is decreased, preventing absorption of vitamin K
bleeding and easy bruising
enlargement of spleen from backflow of blood into the spleen
platelets are destroyed
high risk for bleeding
yellow coloration of skin. liver cells cannot effectively excrete bilirubin.

what is the most common type of cholecystitis
when chemical irritation and inflammation results from gallstones that obstruct the cystic duct, gallbladder neck, or common bile duct
what happens in cholecystitis?
since the gallbladder is inflamed the bile is trapped and reabsorbed and is irritating to the gallbladder wall. causes ischemia and infection when combined with impaired circulation, edema, and gallbladder distention.
results in tissue sloughing with necrosis and gangrene
inflammation of gallbladder without gallstones, associated with biliary stasis caused by any condition that affects the regular filling or emptying or the gallbladder
What is chronic cholecysitis and what are some signs and symptoms?
results from repeated episodes of cystic duct obstruction that cause inflammation.

Gallbladder becomes fibrotic and contracted. Decreased motility and efficient absorption.
Patient will have clay colored stool and dark, foamy urine.
Jaundice and icterus (yellowing of the sclera) occur.
What is the difference between extrahepatic intrahepatic jaundice?
Extrahepatic- occurs from obstructed bile flow from edema of the ducts or gallstones.
Intrahepatic- results from inflammation of the livers bile channels or ducts.
In both, normal flow of bile is blocked and bile salt accumulates in the skin which causes pruritis.
Signs and symptoms for cholecysitis?
Abdominal pain varies. Flatulence, dyspepsia, eructation, anorexia, nausea, vomiting or abdominal pains after fatty foods are eaten.
Pain may radiate to right shoulder or scapula.
Biliary Colic- severe pain that happens when a stone is moving through or lodged in a duct and tissue spasm occurs in order to mobilize the stone through the duct.
What are the diagnostic assessments for cholecystitis?
no tests that are specific.
Increased WBC count can mean inflammation.
Elevated serum levels.
Calcified gallstones can be viewed in x-rays.
Ultrasound in RUQ is the best diagnostic test.
Nonsurgical Management for cholecystitis
- Avoid fatty foods to prevent biliary colic.
- Opioid analgesics for acute biliary pain.
- Anticholinergenic drugs used to relax smooth muscle and decrease ductal tone and spasm.
- Antiemetics- control nausea and vomiting.
- Lithotripsy- break up large stones into small ones.
What is the difference between laprascopic and traditional cholecystectomy?
- surgical removal of the gallbladder.
- Laprascopic- dissect gallbladder for liber bed and cystic artery and duct are closed. Gallbladder is removed through umbilical port. Discharged within a day.
- Traditional- chronic lung disease or heart failure. Large incision to remove gallbladder and locate stones. T-tube is inserted to prevent fluid accumulation (400+ mL qday) Teach pt that feces will pass much more quickly.
Tell me crap about the T-Tube
- main priority for care is to keep drain system below gallbladder.
- semi-fowler position
- Bloody drainage to green/brown bile.
- 400mL qday excreted
- assess for foul odor or purulent drainage.
- Inspect skin around T-tube and insertion site.
- Keep dressing dry.
- NEVER IRRIGATE, ASPIRATE OR CLAMP A T-TUBE. (unless given an order)
- Can clamp when pt is allowed to eat 1-2 hours before and after meals.
- stool will return brown after 7-10 days.
- serious. life-threatening.
- Pancreatic enzymes should be inactive until they reach the small intestine. There is an early activation of the enzymes which results in auto digestion and fibrosis of the pancreas.
What are 4 major processes that occur with acute pancreatitis?
Lipolysis- fatty acids are released and combined with calcium. Body cannot use this combination. Must have calcium by itself. Low calcium levels.
Proteolysis-splitting of proteins by hydrolysis by peptide bonds. May lead to thrombosis or gangrene.
Necrosis of blood vessels-results in bleeding. Can lead to hemorrhaging.
Inflammatory stage- leukocytes have clustered around the necrotic areas in the pancreas.
What are the complications for acute pancreatitis?
Jaundice, Intermittent hyperglycemia.
Cullens sign-turners sign
- Multisystem organ failure.
- Coagulation defects.

Nausea and vomiting resulting in weight loss.
Diagnostic assessments for actue pancreatitis
Serum amylase levels are increased and remain high for 3-4 days.
Trypsin is the most accurate indicator for pain.
Elevated WBC count, ESR and serum glucose levels.
Nonsurgical management for acute pancreatitis
Fasting and rest- NPO durring actue period. IV fluids to maintain hydration. NG tube . Assess for return of peristalsis.
Drug Therapy- PCA pump.
Comfort measures- side-lying position may decrease pain. oxygen for easy breathing. oral hygiene to keep membranes moist.

- assess for unintentional weight loss, muscle wasting, jaundice, dark urine, polyuria.
Diagnosing Chronic Pancreatitis
- based on manifestation, lab and imaging assessment
- CT, MRI, Ultrasounds are done.
- Slightly elevated serum bilirubin and alkaline phosphate levels.
Drug and Nutrition Therapy for Chronic Pancreatitis
- Opioid analgesics
- Pancreatic enzymes are given with meals or snacks to aid in digestion and absorption of fat and protein.
- Drugs to decrease gastric acid.
Surgical Management for Chronic Pancreatitis
If the pancreatic duct sphincter is fibrotic, the surgeon performs a sphincterotomy (incision of the sphincter)
Laparoscopic cholecystectomy- done if biliary tract disease is the cause of pancreatitis.
Done to manage pain
What is the primary surgery for pancreatic cancer?
- Whipple procedure
- removal of the head of the pancreas, duodenum, a portion of the jejunum, stomach and gallbladder.
Pre-op care- catheter into jejunum for feedings. TPN. No bowel prep. NPO 6-8 hours.
Post-op- NPO/ NG tube. Monitor NG drainage. It should be serosanguineous. Semi-fowlers position to reduce tension on suture line. Monitor H&H levels.
What is cataracts what what is it related to?
a opacity of the lens that distorts the image projected onto the retina. Maybe age related or caused by trauma or exposure to toxic agents.
S/S of Cataracts
- Blurred vision, decreased color perception
- lens cloudiness
- double vision that gets worse
- No pain or eye redness associated with age
What is the only cure for Cataracts?
- Extracapsular removal- front capsule is opened with a small incision.
- Phacoemulsification- probe is inserted through the capsule and high-frequency sound waves break up the cataractous lens into small pieces and removed by suction.
After the lens will be replaced because without it, the eye has lost most of its refractive ability and has no accommodative power.
What is post-op care for patients with cataracts?
- Antibiotics immediately.
- Mild itching and bloodshot appearance are normal.
- Avoid aspirin.
- Pain early after surgery is not good. can indicate increase in IOP or hemorrhage.
- Creamy, white, dry, crusty drainage is normal.
Primary open-angle glaucoma
most common. affects both eyes. outflow of aqueous humor through the chamber angle is reduced. IOP increases because fluid cannot leave the eye at the same rate as it is reduced.
S/S- foggy vision, reduced accommodation, mild aching in eyes, headaches.
late symptoms include halos around light, losing peripheral vision, decreased visual acuity. Not correctable with glasses.
- less common. sudden onset. emergency.
- Narrowed angle and forward displacement of the iris. Movement of the iris against the cornea narrows and closes the chamber angle, obstructing the flow of aqueous humor.
What are 4 diagnostic tests for glaucoma?
- Tonometry- shows elevated IOP. 10-21 mmHg. puff of air
- Perimetry- used to test visual fields
- Gonioscopy- when high IOP is found. Determines whether it is an open or closed angle.
- Optic Nerve Imaging- pts with ocular hypertension. assess nerve thickness and contours.
Nonsurgical treatment for patients with glaucoma
- Drug therapy that reduce IOP.
- Eyedrops to prevent an increase in IOP.
Surgical Treatment for glaucoma
Laser trabeculoplasty- burns the meshwork, scarring it and causing the fibers to tighten which improves the outflow of aqueous humor and reduces IOP.
Filtering microsurgery- creates a drainage hole in the iris between the posterior and anterior chamber. If it wont stay open, a shunt can be put in place.
What is the most serious complication from surgery for patients with glaucoma?
Choroidal hemorrhage. If IOP is too low, fluid may enter the suprachoroid space and cause a choroidal detachment. Extra fluid may break blood vessels located there.
S/S- acute pain deep in the eye, decreased vision and vital sign changes.
What happens when you have a ruptured tympanic membrane?
It ruptures and pus or blood drains from the ear.
Can heal ny themselves.
What are the three main symptoms of meniere's disease?
Tinnitus, one-sided sensoineural hearing loss and vertigo
What is Meniere's disease and what are the signs and symptoms of it?
an excess of endolymphatic fluid that distorts the entire canal system. Cause is known but it often occurs with infections, allergic reactions and fluid imbalances.
vertigo, headaches, increasing tinnitus, hearing loss, nausea, vomiting, feeling fullness in affected ear, rapid eye movements.
Nonsurgical Intervention for Meniere's disease
Teach patient to move slowly to prevent worsening of vertigo. Stop smoking. Avoid high salt foods and caffeine.
Meniett device- applies a low-pressure micropulse to the inner ear for 5 minutes three times daily. It displaces the fluid from the inner ear and this relieves manifestations.
What does drug therapy do for Meniere's disease?
aims to control the vertigo and vomiting and restore normal balance.
Mild diuretics to decrease endolymph volume.
Nicotonic acid to vasodilate.
Antihistamines to reduce the severity or stop an acute attack.
What surgical intervention is for Meniere's disease?
Last resort. Labyrinthectomy. involves resection of the vestibular nerve or total removal of the labyrinth. Endolymphatic sac is drained and a small tube is inserted to improve fluid damage.
- Use-laxative, decreases constipation, and blood ammonia level.
- Administration- orally. full glass of fruit juice, water or mild. Rectally with a retention enema
- Teaching- Do not take if you have abdominal pain, nausea, vomiting. Repot electrolyte imbalances. Do not take at bedtime.
- Use- useful in treating Meniere's disease because of its vasodilatory effects. Decreases cholesterol and LDL levels.
- Admin- orally. Dont break, crush, chew or give with meals or milk. IV, give after diluting.
- Teaching- side effects should discontinue after 2 weeks. No alcohol. No sunlight. Report clay colored stool, anorexia, jaundice, sclera.
- Target tissue: Kidney
- Actions: Promotes water reabsorption
- given to relax smooth muscle and decrease ductal tone and spasm
inhibition of Hep C

Four complications of hepatic dysfunction
Hypertension, esophageal varices, ascites and hepatic encephalopathy
Describe skin care for patients with jaundice
Patients nails cut short to prevent excorciation due to pruritis. apply medicated creams and lotions to relieve itching. inspect skin for breakdown and provide support to edematous areas. turn every 2 hours. refrain from using alkaline soap on skin
Home care for patients with ascites
Important to continue health care and seek medical attention if symptoms of complications occur. Discuss proper diet, rest and avoidance of hepatotoxic drugs like acetaminophen, and abstinence of alcohol.
Provide info regarding community support programs
Provide written info about diet, skin care, medications, avoid coughing to prevent hemorrhage
What type of diet should a pt with hepatic failure follow?
foods high in calories, high protein, low fat, low sodium
What are symptoms of hepatic encephalopathy?
neurologic and mental unresponsiveness, sleep disturbances to lethargy and deep coma. Monitor function involving tremors called ASTERIXIS
What are the early and later stages of hepatic encephalopathy?
Early- euphoria, depression, apathy, irritability, memory loss, confusion, yawning, drowsiness, insomnia, agitation
Later- slow slurred speech, emotional lability, impaired judgement, hiccups, slow and deep respirations, hyperactive reflexes. disorientation to time, place and person. As condition worsens, so does the patients mental status. Fetor Hepaticus- musty, sweet odor to breath.
Medications to help control the ammonia in the system
Lactulose, Flagyl, Vancomycin, rifaximin. cathartics and enemas for constipation
Nursing interventions for a patient who is bleeding or has a tendency to bleed easily.
- Avoid aspirin, alcohol and irritating foods. Upper respiratory infections should be treated promptly. Coughing should be controlled.
- Treated with Sondostatin, Vasopressin, Nitroglycerine, inderal, sclerotherapy, ligation of varices and shunt therapy.
What is the most common cause of cirrhosis in the liver?
Characteristics of cirrhosis
Early signs- anorexia, dyspepsia, flatulence, nausea, vomiting, diarrhea, constipation, fever, slight weight loss, enlarged liver and spleen.
Late signs- jaundice, skin lesions, palmar erythema, thrombocytopenia, leukopenia, anemia, coagulation disorders, gynecomastia, loss of axillary and pubic hair, testicular atrophy, impotence

What are the purposes of all three lumens of the Sengstaken-Blakemore tube?
One for each of the two balloons and one for gastric aspiration
Nursing care for a patient with Sengstaken-Blakemore tube
Explain the use of the tube and how it will be inserted. Balloons are checked for patency, lumens should be labeled to prevent confusion. Nursing care includes monitoring for complications of rupture or erosion of the esophagus, regurgitation and aspiration of gastric contents and occlusion of the airway by the balloon. Nursing needs to encourage the patient to expectorate the saliva, frequent oral and nasal care provides relief from the taste of blood and irritation from mouth breathing.
