1500 to 3000 mL/day
The nurse should monitor blood glucose levels for a patient diagnosed with hyperinsulinism. What blood value does the nurse recognize as inadequate to sustain normal brain function?
30 mg/dL Hyperinsulinism is caused by overproduction of insulin by the pancreatic islets. Occasionally, tumors of nonpancreatic origin produce an insulinlike material that can cause severe hypoglycemia and may be responsible for seizures coinciding with blood glucose levels that are too low to sustain normal brain function. (lower than 30)
Acute pancreatitis
80% result from cholelithiasis or sustained alcohol abuse Two main types: interstitial edematous pancreatitis and necrotizing pancreatitis Interstitial pancreatitis affects the majority of patients and is characterized by lack of pancreatic or peripancreatic parenchymal necrosis with diffuse enlargement of the gland due to inflammatory edema; inflammation and edema confined to pancreas; minimal organ dysfunction; return to normal usually within 6 months Necrotizing pancreatitis- there is presence of tissue necrosis in either the pancreatic parenchyma or the tissue surrounding the gland; if parenchyma is involved this is marker for more severe disease; this disease is characterized by widespread and complete enzymatic digestion of the gland; systemic complications from this disease include organ failure, pulmonary insufficiency, hypoxia, shock, kidney disease, GI bleeding; also characterized as having severe acute pancreatitis

Full liquid diet as tolerated Nasogastric tube to intermittent suction for removal of gastric secretions Initiate parenteral feedings first and advance to enteral feedings as tolerated. The nurse should question any order for clear liquid diet because oral intake should be held to inhibit pancreatic enzyme secretion. However, enteral feedings should be initiated as soon as possible, as the client tolerates them. The placement of an NG tube to wall suction is recommended for N/V and abdominal distention only; routine use of an NG tube for removal of gastric secretions in order to limit pancreatic enzymes is not recommended.

Biliary colic is caused by
contraction of the gallbladder which can not release bile due to obstruction by stones; when distended, the fundus of the gallbladder comes in contact with the abdominal wall in the region of the 9th and 10th costal cartilages producing marked tenderness in the RUQ on deep inspiration and prevents full inspiratory excursion

Urinary amylase concentrations also become elevated and remain elevated longer than serum amylase concentrations.
Clinical manifestations of pancreatitis
severe abdominal pain abdominal pain and tenderness and back pain pain often in midepigastrium pain is acute onset, 24-48 hr after heavy meal or alcohol consumption abdominal distention poorly defined, palpable abdominal mass decreased peristalsis vomiting that fails to relieve pain or nausea abdominal guarding rigid or boardlike abdomen may occur indicating peritonitis ecchymosis in the flank or umbilicus may indicate severe pancreatitis N/V fever, jaundice, mental confusion, agitation hypotension is typical and reflects hypovolemia and shock tachycardia, cyanosis, cold, clammy skin acute kidney injury is common respiratory distress and hypoxia diffuse pumlonary infiltrates dyspnea, tachypnea, abnormal blood gas values myocardial depression, hypocalcemia, hyperglycemia, disseminated intervascular coagulation
Mortality rate of patients with acute pancreatitis is 2-10% because of
shock, anoxia, hypotension, or fluid and electrolyte imbalance. This mortality rate may also be related to the 10-30% of patients with severe acute disease characterized by pancreatic and peripancreatic necrosis.
Secretion of GH is increased by _______, _______, and _______.
stress exercise low blood glucose
There are four categories of hormones classified by their _____. They are ________, ________, ________, and ________.
structure amines / amino acids peptides, polypeptides, proteins, glycoproteins steroids fatty acid derivatives
Endocrine glands release hormones into
the bloodstream
The major exocrine function of the pancreas is
to facilitate digestion through secretion of enzymes into the proximal duodenum
The nurse is caring for a patient with acute pancreatitis. The patient has an order for an anticholinergic medication. The nurse explains that the patient will be receiving that medication for what reason?
to reduce gastric and pancreatic secretions
Self digestion of the pancreas by its own proteolytic enzymes, mainly _____, cause acute pancreatitis
trypsin Gallstones obstruct flow of pancreatic juice or cause reflux of bile into the pancreatic duct activating enzymes within the pancreas. Normally, these enzymes would remain inactive until reaching the lumen of the duodenum. Activation of the enzymes can lead to vasodilation, increased vascular permeability, necrosis, erosion, and hemorrhage. Less common causes of pancreatitis- bacterial or viral infection, complication of mumps
Dissolution therapy
use of medication to break up or dissolve gallstones
The _____ nerve also influences exocrine pancreatic secretion
vagus
Diabetes insipidus is caused by a deficiency of _______.
vasopressin (ADH)
