| Question | Answer |
|---|---|
| How specifically are nutrients absorbed? | The inner surface of the small intestine contains millions of tiny fingerlike projections called villi, which are clustered over the entire mucous surface. They are responsible for absorbing the products of digestion into the blood stream. |
| What problem do we observe for and prevent post surgically on ileostomy patients? | Bowel and urinary elimination; fluid and electrolyte balance; tissue perfusion; comfort/pain, nutrition; gas exchange; infection; and in the case of ostomy construction, assessment of the ileostomy and peristomal skin integrity. |
| What do we assess for in patients receiving radiation therapy of the esophagus? | Special problems associated with radiation therapy include the development of an esophagotracheal fistula (an abnormal passage between two internal organs). Aspiration from the fistula and edema from the radiation must be anticipated. |
| What is esophagogastroduodenoscopy? | EGD, enables evaluation of the esophagus, stomach, and duodenum |
| What is achalasia? | Inability of a muscle to relax, particularly the cardiac sphincter of the stomach. |
| What kind of diet will be encouraged for patients with acuyte diverticulitis? | Low fat, hgh fiber |
| How do you plan meals to prevent dumping syndrome? | Treatment includes eating six small meals daily that are high in protein and fat and low in carbohydrates, eating slowly, and avoiding fluids during meals. |
| What precautions do we take with patients with suspected appendicitis? | No pain medications, no heat pack, no enema or laxative |
| What do you do with a stool specimen obtained for ova and parasite? | The specimen should be taken to the laboratory within 30 minutes of collection in specified container. |
| What is strangulated hernia? | The hernia is strangulated when the blood supply and intestinal flow are occluded. Immediate surgical intervention is performed when a hernia strangulates, to prevent anaerobic infection in this affected area. |
| What nursing interventions are implemented s/p a liver biopsy? | Keep the patient lying on the right side for a minimum of 2 hours to splint the puncture site. In this position, the liver capsule is compressed against the chest wall, thereby decreasing the risk of hemorrhage or bile leak. |
| What procedure is performed to reduce ascites? | Paracentesis is a temporary method of removing fluid by withdrawing fluid from the abdominal cavity by either gravity or vacuum. |
| What patient teaching is done for patients to have an esophagoscopy? | After the procedure, keep the patient NPO until gag reflex returns; assess for abdominal pain, tenderness, and guarding. |
| Flapping tremors (asterixis) is seen in patient suffering from what? | Hepatic encephalopathy is a type of brain damage caused by liver disease and consequent ammonia intoxication. |
| Explain what esophagus varices are: | Esophageal varices (a complex of longitudinal, tortuous veins at the lower end of the esophagus) enlarge and become edematous as the result of portal hypertension. |
| What chemical accumulates in patients with cirrhosis? | Ammonia |
| What meds relieve toxic blood levels of ammonia? | Lactulose and Neomycin |

| How is Hepatitis A transmitted? | Oral-fecal route |
| What is an ERCP and what complications do we assess after this procedure? | Dye is injected for radiographic visualization of the common bile duct and pancreatic duct. ERCP of the pancreas is a sensitive and reliable procedure for detecting clinically significant degrees of pancreatic dysfunction -- assess for pancreatitis |
| Why are patients with cirrhosis placed on low-protein or no protein diets? | Proteinis a breaksown product of ammonia and the liver cannot metabolize the ammonia |
| What is Cyclosporine and when is it prescribed? | Cyclosporine is an effective immunosuppressant drug. The use of cyclosporine has been a major factor in the success rates of liver transplantation. It does not cause bone marrow suppression and does not impede wound healing. |
| What complications should you assess for with the patient on Cyclosporine? | Infection |
| What is jaundice and what serum tests are ordered? | Jaundice is the discoloration of body tissues caused by abnormally high blood levels of bilirubin (bilirubin exceeds 2.5 mg/dL). Tests ordered are AST, ALT and LDH |
| What are the common causes of pancreatitis? | Acute or chronic pancreatitis is generally the result of damage to the biliary tract, as by alcohol, trauma, infectious disease, or certain drugs. |
| Why are patients with pancreatitis often NPO? | To avoid stimulating pancreatic activity, and IV fluids are administered. The patient is on NPO status, and an NG tube is inserted to decrease pancreatic stimulation, treat or prevent nausea and vomiting, and decrease abdominal distention. |
| What is the process by which bacteria, cellular debris, and solid particles are destroyed and removed? | Phagocytosis |
| What does differential indicate? | A differential white blood cell count is an examination in which the different kinds of WBCs are counted and reported as percentages of the total examined. They can indicate severe infection |
| Plasma make us what percentage of blood? | 55% |
| What does "shift to the left" indicate? | Severe Infection |
| Where are the erythrocytes produced? | Bone Marrow |
| What is the spleen and what is stored there? | Large lymph organ, stores 500ml (1 pint) of blood which can be released during emergencies, such as hemorrhage, in less than 60 seconds. |
| What is Pernicious Anemia? | Autoimmune disease, inadequate absorption of vit B12 |
| What nursing care is implemented for patients with multiple myeloma? | Pain relief, prevent infection, increase fluids 3-4L to dilute calcium and prevent trauma/injury |
| What side effects occur with iron supplements? | Green or black stools, constipation, teeth discoloration |
| What is the occurrence of sickle cell anemia? | 1:500 of African Americans |
| What is the normal platelet count? | 150,000-400,000 |
