Module 6 Flashcards
Cellular regulation
any process that controls the series of events by which a cell goes through a cell cycle
Cellular growth
increase in the total mass of a cell, cytoplasmic, nuclear, and organelle volume
Cellular reproduction
cells duplicate their contents and divide to yield multiple cells within a similar if not duplicate content
Types of cancer
benign- noncancerous, grow slowly and doesn’t spread
malignant- cancerous, grow rapidly, it invades and destroys nearby normal tissue, spreads throughout the body
Solid tumors
an abnormal mass of tissue does not usually contain liquid or cysts and could be benign or malignant.
results from an error in DNA replication over time or exposure to carcinogens
Some risk factors- are exposure to viruses, exposure to the sun, poor diet choices, immunocompromise
Palliative surgery
it does not cure only relieves the symptoms
Surgeries (solid tumor)
Diagnostic: sample to confirm the diagnosis (ex. Biopsy) or CT scans
Primary treatment: remove the entire or as much of the tumor as possible (and any involved surrounding tissue)
Palliative: when cure isn’t possible; improves comfort
Ionizing radiation is used to interrupt cellular growth
Chemotherapy
antineoplastic agents are used to destroy tumor cells by interfering with cellular functions (especially replication).
nurse intervention- monitor for hypersensitivity, watch for toxicity (cells with rapid growth rates are most susceptible), and the side effects of the treatment/medication
Benign prostate hypertrophy/hyperplasia
an abnormal mass of tissue that does not contain cysts or liquid areas. Hypertrophied lobes of the prostate may obstruct the urethra, causing incomplete emptying of the bladder and urinary retention.
risk factors: african american race, smoking, alcohol consumption, HTN, diabetes, and dietary factors.
Assessment for BPH
get a urinalysis, and renal function test (ex. Cr and BUN> CMP and BMP is the labs for those), urinary retention (bladder scan) treatment is based on severity, urinary catheterization if retention is emergent such as coude catheter
Meds for BPH
alpha-adrenergic blocker: relaxes the smooth muscle of the bladder» improves urine flow (ex. doxazosin, and flomax)
5 alpha-reductase inhibitor: interferes with the conversion of testosterone to dihydrotestosterone (ex. finasteride)
saw palmetto: herbal product better and tolerable but lots of side effects
Gastroesophageal reflux disease (GERD)
backflow of gastric or duodenal contents into the esophagus. Excessive reflux due to an incompetent lower esophageal sphincter, pyloric stenosis, or a motility disorder.
risk factors: overweight, pregnancy, excess alcohol consumption, smoking
manifestations: pyrosis, dyspepsia, regurgitation, and complication is barrets esophagus
Medications for GERD
histamine 2 antagonists: reduces the amount of stomach acid secreted by glands in the lining of the stomach
Ex: Famotidine (Pepcid), Cimetidine (Tagamet)
Proton-pump inhibitors: irreversibly inhibit proton pumps in the stomach; most potent acid inhibitors available
Ex: Pantoprazole (Protonix), Omeprazole (Prilosec)
Antacids: neutralize the acid in the stomach
Ex: Calcium carbonate (Tums), Sodium bicarbonate (Alka-Seltzer Heartburn)
Endoscopy
Scope of GI tract to assess for motility, abnormalities, inflammation, neoplasm, or infection
ERCP
uses endoscopy with X-ray to view ductal structures of the biliary tract and detect/treat bile duct stones, strictures, pancreatic duct disruption
