A, B, E, F Clinical manifestations of acute pancreatitis include pain, vomiting, nausea, fever, abdominal distention, abdominal guarding, abdominal tympany, hypoactive or absent bowel sounds, severe disease, peritoneal signs, ascites, jaundice, palpable abdominal mass, Grey-Turner sign, Cullen sign, and signs of hypovolemic shock. There may be peritonitis involved with pancreatitis and percussion will reveal a tympanic abdomen; bowel sounds will be decreased or absent.

A patient has been admitted with pancreatitis. Which clinical manifestations would the nurse expect to observe in support of this diagnosis? (Select all that apply.) a. epigastric and abdominal pain b. N/V c. diaphoresis d. hyperactive bowel sounds e. fever f. jaundice

D -- The results of physical assessment of a patient with pancreatitis usually reveal hypoactive bowel sounds and abdominal tenderness, guarding, distention, and tympany. Findings that may indicate pancreatic hemorrhage include Grey Turner sign (gray-blue discoloration of the flanks) and Cullen sign (discoloration of the umbilical region); however, they are rare and usually seen several days into the illness.

A patient has been admitted with severe abdominal pain. When examining the patient, the nurse notes hypoactive bowel sounds, abdominal guarding, and a discoloration around the umbilicus. The nurse suspects the patient may have which condition? a. PUD b. esophageal varices c. acute liver failure d. acute pancreatitis

A -- Esophagogastric varices are engorged and distended blood vessels of the esophagus and proximal stomach that develop as a result of portal hypertension secondary to hepatic cirrhosis, a chronic disease of the liver that results in damage to the liver sinusoids. Without adequate sinusoid function, resistance to portal blood flow is increased, and pressures within the liver are elevated. This leads to a rise in portal venous pressure (portal hypertension), causing collateral circulation to divert portal blood from areas of high pressure within the liver to adjacent areas of low pressure outside the liver, such as into the veins of the esophagus, spleen, intestines, and stomach.

A patient is admitted with a GI hemorrhage due to esophageal varices. The nurse knows that varices are caused by which pathophysiologic mechanism? a. portal HTN resulting in diversion of blood from a high-pressure area to a low-pressure area b. superficial mucosal erosions as a result of increased stress levels c. loss of protective mechanisms resulting in the breakdown of mucosa d. inflammation and ulceration secondary to NSAID use

B -- In acute variceal hemorrhage, control of bleeding can be accomplished through the use of pharmacologic agents. Intravenous vasopressin, somatostatin, and octreotide have been shown to reduce portal venous pressure and slow variceal hemorrhaging by constricting the splanchnic arteriolar bed.

A patient is admitted with a GI hemorrhage due to esophageal varices. What medication would the nurse expect the PCP to order for this patient? a. H2 antagonist b. vasopressin c. heparin d. antacids

C -- A major side effect of the medication is systemic vasoconstriction, which can result in cardiac ischemia, chest pain, hypertension, acute heart failure, dysrhythmias, phlebitis, bowel ischemia, and cerebrovascular accident. These side effects can be offset with concurrent administration of nitroglycerin. Other complications include bradycardia and fluid retention.

A patient is admitted with a gastrointestinal hemorrhage due to esophagogastric varices. The patient has been started on a vasopressin drip. The nurse would monitor the patient for which side effect of the medication? a. constipation b. diarrrhea c. chest pain d. bleeding

D -- The initial clinical presentation of the patient with acute GI hemorrhage is that of a patient in hypovolemic shock; the clinical presentation depends on the amount of blood lost. Hematemesis (bright red or brown, coffee ground emesis), hematochezia (bright red stools), and melena (black, tarry, or dark red stools) are the hallmarks of GI hemorrhage.

A patient is admitted with a severe head injury. The nurse knows that critically ill patients are at risk for GI hemorrhage due to stress-related mucosal disease. The nurse should monitor the patient for which signs and symptoms? a. metabolic acidosis and hypovolemia b. decreasing hemoglobin and hematocrit c. hyperkalemia and hypernatremia d. hematemesis and melena

C -- Bariatric procedures are divided into three broad types: (1) restrictive, (2) malabsorptive, and (3) combined restrictive and malabsorptive. The Roux-en-Y gastric bypass combines both strategies by creating a small gastric pouch and anastomosing the jejunum to the pouch. Food then bypasses the lower stomach and duodenum, resulting in decreased absorption of digestive materials. The standard operation for pancreatic cancer is a pancreaticoduodenectomy, also called the Whipple procedure.

A patient was admitted after a Roux-en-Y gastric bypass. A nursing student asks the nurse what type of surgery this is. What would be an appropriate response? a. "It is an esophagectomy performed using a transthoracic approach." b. "It is an esophagectomy performed using a transhiatal approach." c. "It is a combination of restrictive and malabsorption types of bariatric surgery." d. "It is a standard operation for pancreatic cancer."

C -- In acute pancreatitis, the normally inactive digestive enzymes become prematurely activated within the pancreas itself, creating the central pathophysiologic mechanism of acute pancreatitis, namely autodigestion.

A patient was admitted with acute pancreatitis. The nurse understands that pancreatitis occurs as a result of what pathophysiologic mechanism? a. Uncontrolled hypoglycemia caused by an increased released of insulin b. Loss of storage capacity for senescent RBCs c. premature activation of inactive digestive enzymes, resulting in autodigestion d. release of glycogen into the serum, resulting in hyperglycemia

B -- Esophagectomy is usually performed for cancer of the distal esophagus and gastroesophageal junction.

A patient was admitted with severe epigastric pain and has been diagnosed with cancer. The patient is scheduled for an esophagectomy. The patient asks about the procedure. What would be an appropriate response from the nurse? a. "This procedure is usually performed for cancer of the proximal esophagus and gastroesophageal junction." b. "This procedure is usually performed for cancer of the distal esophagus and gastroesophageal junction." c. "This procedure is usually performed for cancer of the pancreatic head." d. "The procedure is usually performed for varices of the distal esophagus and gastroesophageal junction."

B -- As the patient moves toward discharge, teaching should focus on the interventions necessary for preventing the recurrence of the precipitating disorder. If an alcohol abuser, the patient should be encouraged to stop drinking and be referred to an alcohol cessation program.

A patient with a history of chronic alcoholism was admitted with acute pancreatitis. The nurse is developing a patient education plan. Which topic would the nurse include in the plan? a. diabetes management b. alcohol cessation c. occult blood testing d. anticoagulation management

A -- Because pancreatitis is often associated with massive fluid shifts, intravenous crystalloids and colloids are administered immediately to prevent hypovolemic shock and maintain hemodynamic stability. Electrolytes are monitored closely, and abnormalities such as hypocalcemia, hypokalemia, and hypomagnesemia are corrected. If hyperglycemia develops, exogenous insulin may be required.

A patient with a history of chronic alcoholism was admitted with acute pancreatitis. What intervention would the nurse include in the patient's plan of care? a. monitor the patient for hypovolemic shock from plasma volume depletion b. observe the patient for hypoglycemia and hypercalcemia c. initiate enteral feedings after the NG tube is placed d. place the patient on a fluid restriction to avoid the fluid sequestration

B -- Pain management is a major priority in acute pancreatitis. Administration of around-the-clock analgesics to achieve pain relief is essential. Morphine, fentanyl, and hydromorphone are the commonly used narcotics for pain control. Relaxation techniques and the knee-chest position can also assist in pain control. However, the patient's pain needs to be addressed first.

A patient with acute pancreatitis is complaining of a pain in the left upper quadrant. Using a 1-10 pain scale, the patient states the current level is at an 8. What intervention would the nurse include in the plan of care? a. administer analgesics only as needed b. administer analgesics around the clock c. educate the patient and family on lifestyle changes d. teach relaxation and distraction techniques

C -- Side effects of histamine antagonists include central nervous system (CNS) toxicity (confusion or delirium) and thrombocytopenia.

C -- Lactulose, a synthetic ketoanalogue of lactose split into lactic acid and acetic acid in the intestine, is given orally through a nasogastric tube or as a retention enema. The result is the creation of an acidic environment that results in ammonia being drawn out of the portal circulation. Lactulose has a laxative effect that promotes expulsion. Vitamin K is used to help control bleeding. Insulin would be given to control hyperglycemia. Use of benzodiazepines and other sedatives is discouraged in a patient with acute liver failure because pertinent neurologic changes may be masked, and hepatic encephalopathy may be exacerbated.
