Term
Since PKD is one of the MOST COMMON INHERITED DISORDERs, does this mean it is only congenital?
Definition
No, it is imp to know it is one of the most common inherited diseases, but there is 5-10% with PKD who have NO FAMILY HX.
Term
Who is PKD most common in?
Definition
Caucasians
Term
What happens with PKD? Are cysts ONLY ON THE KIDNEYS with this disease??
Definition
PKD causes fluid filled cysts to grow and it will eventually replace the functioning nephron tissue which leads to renal failure. Key to know is: cysts often grow in other parts of the body. About 40% have compromised renal function and in other organs. Cysts can form in other tissue such as the liver, brain, and blood vessels. (the rupture in the last 2 are the most likely to kill you!) Really listen if they have a headache.
Term
What is to know about the 2 forms of PKD?

HYPERTENSION
Term
What are the key features of PKD? What is often the presenting symptom?
Definition
Abd or flank pain is often the presenting symptom of PKD. Other features are: Nocturia (as kidney gets bigger, increased night peeing), have distended abds & increased girth, constipated b/c of the increased size, they have "bloody or cloudy" urine, get kidney stones and HYPERTENSION!
Term
What assessment findings are looked for & found with PKD?
Definition
UA: shows proteinuria and/or hematuria. Serum BUN & creatinine are increased & assesses the kidney fx. A renal sonogram, CT or MRI scan.
Term
During assessment, should you palpate a suspected or diagnosed PKD patient?
Definition
No, do NOT palpate PKD pt's - you could rupture a cyst.
Term
How can we prevent PKD?
Definition
There is no way to prevent PKD, at present. Although early detection and mgmt of HTN may slow the progression of renal impairment. Perhaps genetic counseling if parents have PKD and want kids.

What is done to treat/help patients with PKD? What is avoided too?
Definition
MANAGE PAIN, but avoid NSAIDs! TREAT CONSTIPATION (increase fluids, increase fiber, regular exercise) TREAT HYPERTENSION (ace inhibitors are BEST! the "prils") EDUCATE THE PATIENT on the disease and on renal failure + transplant (PKD most likely ends in renal failure unfortunately)
Term
Client education for PKD:

Definition
Diabetic Nephropathy
Term
50% of diabetics will develop nephropathy after having diabetes for 20 years. The more damage there is over time + more BG is off = more damage done to the kidneys. The point is ...
Definition
Must control blood glucose to save your kidneys. Remember, diabetic nephropathy is the # 1 cause of ESRD. Diabetes is # 1, but it's followed close by HTN. Obesity + diabetes + HTN = renal failure

STAGE 2, 2-3 YEARS AFTER DIAGNOSIS: glomerular & tubular capillary basement membrane changes result in microscopic changes, with loss of filtration surface area and scar formation. glomerular changes are called glomerulosclerosis. STAGE 3, 7-15 YRS AFTER DIAGNOSIS: miroalbuminuria is present. The GFR may still be normal or may be increased. STAGE IV: Albuminuria is detectable by dipstick. GFR is decreased. BP is increased, an retinopathy is present. STAGE V: GFR decreases at an average reate or 10 mL/min/yr.
Term
What kind of substances are very important for diabetics to avoid... to save their kidneys?
Definition
Diabetics need to avoid NEPHROTOXIC SUBSTANCES (such as aminoglycoside antibiotics and contrast dyes). Doses are adjusted for diabetics & renal patients. It's a fine line, do you take care of another problem or hurt their kidneys?
Term
Clients with worsening renal function may have frequent hypoglycemic episodes and reduced need for insulin. Why does this not mean that their diabetes is getting "better"?
Definition
Explain to the client that the kidneys metabolize & excrete insulin. This really just means their renal function is getting worse. When renal function is reduced, the insulin is available for longer amt of time & so less insulin is needed. Unfortunately, many clients believe this means their diabetes is improving. THe result is more rapid progression of ESRD.

What are common nursing diagnoses for clients with acute pancreatitis?
Definition
1. Acute Pain related to biologic and injury agents (pancreatic inflammation and enzyme leakage) 2. Imbalanced Nutrition: Less than body requirements related to the inability to ingest food and absorb nutrients
Term
Abd pain is the prominent symptom of pancreatitis. The main focus of nursing care is aimed at reducing discomfort and pain by the use of interventions that decrease GI tract activity. What are the nonsurgical initial attempts by HC workers to relieve pain? What are the pain medications given to relieve pain associated with Pancreatitis? <-- last is the important one!
Definition
Initially attempts to relieve pancreatitis pain is fasting (to rest the pancreas & reduce pancreatic enzyme secretion), drug therapy, and comfort measures. Drugs given to decrease pain are OPIOIDS by means of a PCA pump. MEPERIDINE (DEMEROL) is the traditional drug of choice for relieving abdominal pain assoc with acute pancreatitis. Other opioids include FENTANYL & MORPHINE>
Term
Why is an NG tube used for patients with Acute Pancreatitis?
Definition
Fasting is done to rest the pancreas and reduce pancreatic enzyme secretion, food and fluids are withheld in the acute period. NG drainage and suction is reserved for clients who have continuous vomiting or biliary obstruction. Gastric decompression prevents gastric digestive juices from flowing into the duodenum. B/c paralytic ileus is a common complication of acute pancreatitis, prolonged NG tube intubation may be necessary. Assess frequently for the presence of bowel sounds, including before the NG tube is removed.
Term
Chronic Pancreatitis patients stool looks like what?
Definition
Steatorrhea (excessive amounts of fat in stool). This is d/t pancreatic enzyme secretion being reduced by more than 80% & the resulting severe malabsorption of fats. These stools are pale, bulky, and frothy & have an offensive odor. There is also increased proteins in stool. If you inspected the stool, the fat content would be visible. In chronic pancreatitis, stool fat output may exceed 40 g/day.

Definition
it's a minimally invasive surgery, is performed much more than open surgery (the other option), complications are not common, death rate is vey low, bile duct injuries are rare, client recovery is faster, postop pain is less severe. There is no special preop prep (besides NPO), very small midline puncture by umbilicus, abd cavity is inflated with 3-4 L of CO2 (promote ambulation d/t this), far less opioids are necessary postop, usually discharges within 1 day. Following laproscopic surgeries, they return to work & normal activities much sooner than an open. Usual activities resume in 1-3 weeks.
Term
Now, contrast the Laparoscopic & discuss the other Open Cholecystemtomy (Gallbladder removal)...
Definition
Use of the traditional/open surgery has declined in the last decade. Hospitalization is required for several days, galbladder is removed through incision in right & then explores bile ducts, the surgeon typically inserts a T-tube to ensure patency of the duct, additionally a JP drain is used to prevent fluid accumulation, postop is Demerol via PCA pump for pain relief, the surg dressing & drain removed w/in 24 hrs, but T-tube may be in for 6 weeks, gradually advance diet from clear liquids to solid foods.
Term
What is a T-tube often used for in an Open Cholecystectomy (gallbladder removal)?
Definition
It ensures patency of the bile duct & may be left in for 6 weeks following surgery. In immediate post-op period expect bloody drainage, which changes to green-brown bile. Bile output is about 400+ mL/day with a gradual decrease in amount. Report excess of 100 mL/day. NEVER irrigate, aspirate or clamp a T-tube without a physician's order. Assess drainage system for pulling, kinking or tangling of tubing. When the client is allowed to eat, clamp the T tube (per physicians orders) before and after meals. assessthe clients response to determine tolerance of food.
Term
What differentiates Crohns & Ulcerative Colitis?
Definition
Crohns: begins in intermittent ileum (lower part of long small intestine) w/ patchy involvement through all layers of bowel. Ulcerative Colitis: begins in Rectum & proceeds toward cecum (reverse way through the bowel). They both have unknown etiology. Crohns occurs in 15-40 yo's. Ulcerative COlitis occurs 15-25 & 55-65 yo's. Crohns stools are 5-6 loose stools/day with NO blood. Ulcerative COlitis is 10-20 liquid & bloody stools/day. They both have complications of fistulas & nutritional deficiencies, but ulcerative colitis additionally has hemorrhage & perforation.
Term
Intestinal/Bowel obstructions are partial or complete & classified as "mechanical" & "non-mechanical." what are each?
Definition
Mechanical obstruction is a physical obstruction (could be hernia, adhesion, tumor, stricture or fecal impaction) Non-Mechanical Obstruction (aka paralytic ileus) does not involve a physical obstruction. Instead, peristalsis is decreased or absent, causing a slowing or a back up of intestinal contents.
Term
What are the signs/symptoms of Mechanical bowel obstructions?
Definition
abdominal pain, cramping. Can be sporadic (if partial) or localized and steady (if complete). Vomiting often acompanies obstruction. When you examine the abd, look for abd distention (common in all forms of intestinal obstruction). Ausculate for high-pitched bowel sounds (occurs proximal to obstruction as intestine tries to push it fwd). Below the obstruction, the bowel sounds will be absent.
Term
What are the signs/symptoms of nonmechanical bowel obstruction?
Definition
Nonmechanical (paralytic ileus) pain is a constant discomfort. Colicky cramping is not characteristic of this type of obstruction. Abd Distention is typically present. Ausculation will have decreased bowel sounds in early obstruction and absent bowel sounds in later stages. Vomiting of gastric contents & bile is frequent.

Definition
Ammonia
Term
____________ is the accumulation of excess free fluid within the peritoneal cavity. Most commonly occurs in cirrhosis of the liver. Can lead to a distended abdomen.
Definition
Ascites
Term
How does Ascites (n excessive amount of fluid built up within the peritoneal cavity) affect the diaphragm?
Definition
Breathing can be affected as the fluid-filled peritoneal cavity presses upon the diaphragm, a very necessary component of respiration. When pressure on the diaphragm from fluid build-up occurs, it lessens the ability of these diaphragm muscular fibers to expand and contract, and results in impaired breathing.
Term
_________ ___________ is a persistent increase in pressure within the portal vein, it is a major complication of cirrhosis. It results from increased resistance to obstruction of the flow of blood through the portal vein and its tributaries. Blood flow backs up into the spleen (causing splenomegaly). Veins in the esophagus, stomach, intestines, abdomen, and rectum become dilated.
Definition
PORTAL HYPERTENSION
Term
What is the relationship between cirrhosis of the liver & bleeding?
Definition
Bleeding esophageal varices occur when veins in the walls of the lower part of the esophagus and sometimes the upper part of the stomach are wider than normal (dilated). Bleeding varices are a life-threatening complication of increased blood pressure in the portal vein caused by liver disease (portal hypertension). The portal vein carries blood from the intestine to the liver. Increased pressure causes the veins to balloon outward. The vessels may break open (rupture). Any cause of chronic liver disease can cause bleeding varices. Signs are vomiting blood & black/tarry stools.
Term
What teaching does a nurse do with cirrhosis patients upon discharge?
Definition
Discharge Planning should include stressing the need to abstain/avoid alcohol & ilicit drugs. Tell them Do not consume any alcohol. Seek support services help if needed. By avoiding alcohol & drugs the client: prevents further scarring of the liver, allows the liver to heal & regenerate, prevents gastric & esophageal irritation, reduces the incidence of bleeding and prevents other life-threatening complications.
Term
The goal that has the highest priority for a client has a massive bleed from esophageal varices is to:
Definition
MAINTAIN A PATENT AIRWAY. The nurse should position the client to prevent aspiration and assess respirations and oxygen saturation. The nurse should assist HC provider in controlling the hemorrhage with a balloon tamponade. Third priority is to restore circulating blood volume with blood & IV fluids.
Term
The client is admitted to the hospital with a diagnosis of acute GI bleeding, which nursing diagnosis takes highest priority for this client?
Definition
deficient fluid volume related to bleeding
Term
Acute GI bleeds are one of the most common medical emergencies encountered today. Although bleeding stops spontaneously in 80% – 90% of cases, patients presenting with sudden blood loss are at risk for...
Definition
decreased tissue perfusion and oxygen-carrying capability, which can affect every organ system in the body. If the patient has active, acute bleeding, begin resuscitation efforts immediately. As always, an assessment of airway, breathing, and circulation is a top priority. Protection of the airway with intubation may be needed to avoid respiratory compromise from aspiration of blood, especially in patients with altered mental status. Provide oxygen as needed, and begin cardiac monitoring. For patients in hypovolemic shock, they will require IV fluid volume replacement. Insert at least two large-bore IV catheters and administer normal saline, the fluid of choice, to maintain mean arterial pressure at 60 mm Hg or higher. Do not use normal saline for patients with liver disease, however, as it may lead to ascites; use Ringer’s lactate solution instead.
Term
a pt with a hx of cirrhosis of the liver has been admitted to the ER with massive, bright red hematemesis. The nurses first priority is to: a) initiate 2 IV lines with 18 gauge catheters b) prepare for endoscopy by performing a gastric lavage with NS c) perform a focused nursing assessment d) draw blood to be sent to the lab for a type & cross match
Definition
c) perform a focused assessment - The nurse must first assess for signs of shock by checking VS, urine output, and signs of decreased peripheral perfusion. Remember, in most situations assessment comes first.
Term
Deep tenderness at ___________ point is a sign of acute appendicitis. Where is this located?
