Patho Exam 2 Friday Flashcards
Peritonitis: Describe, manifestations, acute vs. Chronic
Inflammation of the peritoneum activates several protective mechanisms
A thick, sticky exudate that bonds nearby structures and temporarily seals them off
Abscesses may form in an attempt to wall off the infections
Peristalsis may slow down in a response to the inflammation, decreasing spread of toxins/bacteria
Causes: chemical irritation (e.g., ruptured gallbladder or spleen) or direct organism invasion (e.g., appendicitis and peritoneal dialysis)
Manifestations usually sudden and severe; classical manifestation is abdominal rigidity
Abdominal tenderness and pain, decreased peristalsis, intestinal obstruction, nausea/vomiting
Large volumes of fluid leak into the peritoneal cavity
Indicators of infection, sepsis, or shock
MEDICAL EMERGENCY
Rigid abdomen, severe pain, anorexia
Bowel obstructions: describe, manifestations, most common
Manifestations: abdominal distension, abdominal cramping, colicky pain, nausea, vomiting, constipation, diarrhea, borborygmi, intestinal rushes, decreased or absent bowel sounds, restlessness, diaphoresis, tachycardia progressing to weakness, confusion, and shock/MOST COMMON CAUSE OF BOWEL OBSTRUCTIONS ARE ADHESIONS
Hiatal hernia: describe manifestations, how does it feel
A stomach section protrudes upward through an opening in the diaphragm toward the lung
Causes: weakening of the diaphragm muscle, frequently resulting from increased intrathoracic pressure or increased intra-abdominal pressure; trauma; congenital defects
Risk factors: advanced age and smoking
Manifestations include indigestion, heartburn, frequent belching, nausea, chest pain, strictures, dysphagia, and soft upper abdominal mass (protruding stomach pouch)
Worsen with recumbent positioning, eating (especially after large meals), bending over, coughing
Intra abdominal pressure
Diarrhea and antibiotics use: what can it lead to?
antibiotic: destruction of the normal gut flora!
PUD: describe, manifestations
Peptic ulcer disease (PUD): lesions affecting stomach lining or duodenum
Leads to heartburn
H Pylori: associated with ?
PUD
Intussusception: describe, manifestations, what could this lead to?

Can lead to bowel obstructions
Viral hepatitis : Review all
A—Fecal-Oral Route
B—Sexual Contact/ Needles/Tears and Saliva
C—Blood-to-Blood
D—Only if you already have Hep B
E—Fecal-Oral Route
Viral hepatitis is contagious but most will recover with sufficient time
Advancing age and comorbidity increase the likelihood that liver failure, liver cancer, or cirrhosis will develop
Cleft palate: describe
Associated with genetic mutations
Appendicitis: describe, manifestations, where is the pain usually?
Inflammation of the vermiform appendix, most often caused by an infection
Triggers local tissue edema, which obstructs the small structure
As fluid builds inside the appendix, microorganisms proliferate
Appendix fills with purulent exudate and area blood vessels become compressed
Ischemia and necrosis develop; pressure inside the appendix escalates, forcing bacteria and toxins out to surrounding structures
–Manifestations vary from asymptomatic to sudden and severe
Sharp abdominal pain develops, gradually intensifies (over about 12–24 hours), and becomes localized to the lower right quadrant of the abdomen (McBurney point)
Pain may occur anywhere in abdomen; will temporarily subside if the appendix ruptures, and then the pain will return and escalate
—Manifestations
Nausea, vomiting, abdominal distension, and bowel pattern changes
Indications of inflammation and infection (e.g., fever, chills, and leukocytosis)
Indications of peritonitis (e.g., abdominal rigidity, tachycardia, and hypotension)
–Urgent diagnosis and treatment are crucial
–RLQ pain, fever, nausea, diarrhea, rebound tenderness
GERD: describe, manifestations, what can chronic GERD lead to?
Gastroesophageal reflux disease (GERD): chyme or bile periodically backs up from the stomach into the esophagus, irritating the esophageal mucosa
Causes: certain foods (e.g., chocolate, caffeine, carbonated beverages, citrus fruit, tomatoes, spicy or fatty foods, and peppermint), alcohol consumption, nicotine, hiatal hernia, obesity, pregnancy, certain medications (e.g., corticosteroids, beta blockers, calcium-channel blockers, and anticholinergics), nasogastric intubation, and delayed gastric emptying
Manifestations: heartburn, epigastric pain (usually after a meal or when recombinant), dysphagia, dry cough, laryngitis, pharyngitis, regurgitation of food, and sensation of a lump in the throat
—esophageal cancer
Gastroenteritis-left untreated leads to?

May be congenital or acquired
Thought to be caused by a low-fiber diet and poor bowel habits that result in chronic constipation
–Diverticulitis: diverticula become inflamed, usually because of retained fecal matter (often asymptomatic until it becomes serious)
Potential for fatal obstruction, infection, abscess, perforation, peritonitis, hemorrhage, and shock

Blood is irritating to the gastric mucosa
Can occur from any conditions that cause upper GI bleeding
Pyelonephritis: describe, manifestations : Pre, Intra, Post ? major organism
Acute or chronic infection that has reached one or both kidneys
Kidneys become grossly edematous and fill with exudate, compressing renal artery and potentially developing abscesses or necrosis
Complications: renal failure, recurrent UTIs, and sepsis
Manifestations: severe UTI symptoms, flank pain, and increased blood pressure
—Most common organism: Ecoli-Acute
At risk: ascending urinary tract (going back up)
Intrarenal injury
Dialysis : what is it for? What major electrolyte should we watch out for if a patient skipped dialysis and why?
To remove excess fluid and waste
—When your kidneys are damaged, they produce less erythropoietin (EPO), a hormone that signals your bone marrow—the spongy tissue inside most of your bones—to make red blood cells. With less EPO,your body makes fewer red blood cells, and less oxygen is delivered to your organs and tissues.
Obstruction in the renal system: Pre, Intra, Post: KNOW ALL THREE-REMEMBER TOP, MIDDLE BOTTOM
Prerenal–Sudden and severe drop in blood pressure(shock) or interruption of blood flow to the kidneys from severe injury or illness.
Intrarenal–Direct damage to the kidneys, by inflammation, toxins, drugs, infection, or reduced blood supply
Postrenal–Sudden obstruction of urine flow due to enlarged prostate, kidney stones, bladder tumor, or injury
Oliguric phase of AKI
Oliguric (daily urine output <400 mL): electrolyte disturbances, fluid volume excess, azotemia, and metabolic acidosis
Diruretic phase of AKI
Diuretic phase (daily urine output >5 L): electrolyte disturbances, dehydration, and hypotension
Recovery phase of AKI
Recovery phase: glomerular function gradually returns to normal
CKD-HTN/DM
Hypertension
Diabetes
Glomerulonephritis : describe, manifestations: Nephritic syndrome
Acute or chronic bilateral inflammatory disorder of the glomeruli that typically follows a streptococcal infection; leading cause of renal failure
Inflammatory changes impair the kidneys’ ability to excrete waste and excess fluid
Nephrotic and nephritic syndromes are the most prevalent forms
—Results in increased glomerular capillary permeability, leading to marked proteinuria, lipiduria, hypoalbuminemia, and anasarca
Other manifestations: hypoalbuminemia, dark and cloudy urine, immunoglobulins in the urine
—-Manifestations: gross hematuria, urinary casts and leukocytes, low GFR, azotemia, oliguria, and high blood pressure
Flow of filtration through the kidneys
Each nephron contains multiple sections responsible for filtering specific substances
Bowman’s capsule: double membrane that surrounds the glomerulus
Glomerulus: cluster of capillaries
Blood enters glomerulus through an afferent arteriole, leaves it through efferent
Nephrolithiasis: describe, manifestations: Pre, Intra, Post ?
Presence of renal calculi, hard crystals composed of minerals that the kidneys normally excrete, in renal pelvis, ureters, or bladder
—-Manifestations: colicky pain in the flank area that radiates to the lower abdomen and groin; bloody, cloudy, or foul-smelling urine; dysuria; frequency; genital discharge; nausea; vomiting; fever; and chills
——–Post renal injury

BPH: describe, manifestations: Pre, Intra, Post ? Risks ?
A common, nonmalignant enlargement of the prostate gland that occurs as men age; the exact cause is unknown but it may result in urinary stasis and UTIs
—As the prostate expands, it presses against the urethra and obstructs urine flow
Manifestations: frequency, urgency, retention, difficulty initiating urination, weak urinary stream, dribbling urine, nocturia, bladder distension, overflow incontinence, and erectile dysfunction
—Weak stream, nocturia, difficulty initiating stream
Men over 50 with BPH are at risks for UTIs.

UTI/cystitis: describe, manifestations, major organism/why are women at risks?
Major organism Ecoli
Women more at risk due to shorter urethra
Highest risks for UTI, sexually active women
#1 sign: dysuria
—-Inflammation of the bladder
The bladder and urethra walls become red and swollen
Causes: infection and irritants
Manifestations: UTI symptoms, abdominal pain, and pelvic pressure
Diagnosis and treatment follow those usually seen for UTIs
