The nursing student has just reviewed material in the course textbook regarding pancreatitis. The student knows that a major symptom of pancreatitis that causes the client to seek medical care is:

Severe abdominal pain

Gynecomastia is a common side effect of which of the following diuretics?

Spironolactone Rationale: Gynecomastia is a common side effect caused by spironolactone. Vasopressin is used for bleeding esophageal varices and is not a diuretic. Nitroglycerin (IV) may be used with vasopressin to counteract the effects of vasoconstriction from the vasopressin.

The nurse understands that a client with diabetes mellitus is at greater risk for developing which of the following complications?

Urinary tract infections

A client is being evaluated for hypothyroidism. During assessment, the nurse should stay alert for:

decreased body temperature and cold intolerance. Rationale: Hypothyroidism markedly decreases the metabolic rate, causing a reduced body temperature and cold intolerance. Other signs and symptoms include dyspnea, hypoventilation, bradycardia, hypotension, anorexia, constipation, decreased intellectual function, and depression. Exophthalmos; conjunctival redness; flushed, warm, moist skin; and a systolic murmur at the left sternal border are typical findings in a client with hyperthyroidism.

Although not designated as endocrine glands, several organs within the body secrete hormones as part of their normal function. Which organ secretes hormones involved in increasing blood pressure and volume and maturation of red blood cells?

kidneys

A nurse is caring for a patient with cancer of the liver whose condition has required the insertion of a percutaneous biliary drainage system.

Document the presence of normal bile output.

Which feature(s) indicates a carpopedal spasm in a client with hypoparathyroidism?

Hand flexing inward Rationale: Carpopedal spasm is evidenced by the hand flexing inward. Cardiac dysrhythmia is a symptom of hyperparathyroidism. Moon face and buffalo hump are the symptoms of Cushing syndrome. A bulging forehead is a symptom of acromegaly.

Ammonia, the major etiologic factor in the development of encephalopathy, inhibits neurotransmission. Increased levels of ammonia are damaging to the body. The largest source of ammonia is from:

The digestion of dietary and blood proteins.

Which combination of adverse effects should a nurse monitor for when administering IV insulin to a client with diabetic ketoacidosis?

Hypokalemia and hypoglycemia

A patient who is diagnosed with type 1 diabetes would be expected to:

Need exogenous insulin.

Which of the following factors would a nurse identify as a most likely cause of diabetic ketoacidosis (DKA) in a client with diabetes?

The client has eaten and has not taken or received insulin. Rationale: If the client has eaten and has not taken or received insulin, DKA is more likely to develop. Hypoglycemia is more likely to develop if the client has not consumed food and continues to take insulin or oral antidiabetic medications, if the client has not consumed sufficient calories, or if client has been exercising more than usual.

A client has undergone a liver biopsy. After the procedure, the nurse should place the client in which position?

On the right side

The nurse is preparing a care plan for a client with hepatic cirrhosis. Which nursing diagnoses are appropriate? Select all that apply.

Sensitive to heat

When describing the difference between endocrine and exocrine glands, which of the following would the instructor include as characteristic of endocrine glands?

The secretions are released directly into the blood stream.

While conducting a physical examination of a client, which of the following skin findings would alert the nurse to the liklihood of liver problems? Select all that apply.

Jaundice Petechiae Ecchymosis

A client with liver and renal failure has severe ascites. On initial shift rounds, his primary nurse finds his indwelling urinary catheter collection bag too full to store more urine. The nurse empties more than 2,000 ml from the collection bag. One hour later, she finds the collection bag full again. The nurse notifies the physician, who suspects that a bladder rupture is allowing the drainage of peritoneal fluid. The physician orders a urinalysis to be obtained immediately. The presence of which substance is considered abnormal?

Albumin Rationale: Albumin is an abnormal finding in a routine urine specimen. Ascites present in liver failure contain albumin; therefore, if the bladder ruptured, ascites containing albumin would drain from the indwelling urinary catheter because the catheter is no longer contained in the bladder. Creatinine, urobilinogen, and chloride are normally found in urine.

A nurse is preparing a client with type 1 diabetes for discharge. The client can care for himself; however, he's had a problem with unstable blood glucose levels in the past. Based on the client's history, he should be referred to which health care worker?

Dietitian

A client is actively bleeding from esophageal varices. Which medication would the nurse most expect to be administered to this client?

Octreotide Rationale: In an actively bleeding client, medications are administered initially because they can be obtained and administered quicker than other therapies. Octreotide (Sandostatin) causes selective splanchnic vasoconstriction by inhibiting glucagon release and is used mainly in the management of active hemorrhage. Propranolol (Inderal) and nadolol (Corgard), beta-blocking agents that decrease portal pressure, are the most common medications used both to prevent a first bleeding episode in clients with known varices and to prevent rebleeding. Beta-blockers should not be used in acute variceal hemorrhage, but they are effective prophylaxis against such an episode. Spironolactone (Aldactone), an aldosterone-blocking agent, is most often the first-line therapy in clients with ascites from cirrhosis. Lactulose (Cephulac) is administered to reduce serum ammonia levels in clients with hepatic encephalopathy.

A client is admitted to the healthcare facility suspected of having acute pancreatitis and undergoes laboratory testing. Which of the following would the nurse expect to find?

Elevated urine amylase levels

A nurse should perform which intervention for a client with Cushing's syndrome?

Explain that the client's physical changes are a result of excessive corticosteroids.

A client has received a diagnosis of portal hypertension. What does portal hypertension treatment aim to reduce? Select all that apply.

Fluid accumulation Venous pressure

Which condition in a client with pancreatitis makes it necessary for the nurse to check fluid intake and output, check hourly urine output, and monitor electrolyte levels?

Frequent vomiting, leading to loss of fluid volume

A client is being tested to determine the presence of an insulinoma. Which symptoms will the nurse expect to assess in this client? Select all that apply.

Seizure activity Generalized weakness Mental confusion Blood glucose level of 46 mg/dl

A client with cirrhosis has portal hypertension, which is causing esophageal varices. What is the goal of the interventions that the nurse will provide?

Reduce fluid accumulation and venous pressure.

A nurse should perform which intervention for a client with Cushing's syndrome?

Explain that the client's physical changes are a result of excessive corticosteroids. Rationale: The nurse should explain to the client that Cushing's syndrome causes physical changes related to excessive corticosteroids. Clients with hyperthyroidism, not Cushing's syndrome, are heat intolerant and must have cool clothing and bedding. Clients with Cushing's syndrome should have a high-protein, not low-protein, diet. Clients with Addison's disease must increase sodium intake and fluid intake in times of stress of prevent hypotension.

The nurse is administering medications to a client that has elevated ammonia due to cirrhosis of the liver. What medication will the nurse give to detoxify ammonium and to act as an osmotic agent?

Lactulose

A client was admitted to a critical care unit with esophageal varices and a precarious physical condition. What predisposes the client to have bleeding varices? Select all that apply.

Little protective tissue to protect fragile veins Chemical irritation Straining at stool Rough food

A client seeks medical attention for new onset of weight loss and heat intolerance. Which additional statements indicate to the nurse that the client is experiencing hyperthyroidism? Select all that apply.

"I switched from knitting to glue projects since I have developed tremors in my hands." "Even sitting still, sometimes it feels like my heart is racing." "My children tell me that my eyes appear to be bigger, almost buldging, particularly when I tell them to do the dishes."

A client discharged after a laparoscopic cholecystectomy calls the surgeon's office reporting severe right shoulder pain 24 hours after surgery. Which statement is the correct information for the nurse to provide to this client?

"This pain is caused from the gas used to inflate your abdominal area during surgery. Sitting upright in a chair, walking, or using a heating pad may ease the discomfort."

A student accepted into a nursing program must begin receiving the hepatitis B series of injections. The student asks when the next two injections should be administered. What is the best response by the instructor?

"You must have the second one in 1 month and the third in 6 months."

A patient who is 6 months' pregnant was evaluated for gestational diabetes mellitus. The doctor considered prescribing insulin based on the serum glucose result of:

138 mg/dL, 2 hours postprandial.

Glycosylated hemoglobin reflects blood glucose concentrations over which period of time?

3 months

Pharmacologic therapy frequently is used to dissolve small gallstones. It takes about how many months of medication with UDCA or CDCA for stones to dissolve?

6 to 12

The nurse is aware that the best time of day for the total large corticosteroid dose is between:

7:00 AM and 8:00 AM Rationale: The best time of day for the total large corticosteroid dose is in the early morning, between 7:00 AM and 8:00 AM, when the adrenal gland is most active. Therefore, dosage at this time of day will result in the maximum suppression of the adrenal gland.

The nurse is reviewing a client's laboratory studies and determines that the client has an elevated calcium level. What does the nurse know will occur as a result of the rise in the serum calcium level?

A rise in serum calcium stimulates the release of calcitonin from the thyroid gland.

A client is evaluated for severe pain in the right upper abdominal quadrant, which is accompanied by nausea and vomiting. The physician diagnoses acute cholecystitis and cholelithiasis. For this client, which nursing diagnosis takes top priority?

Acute pain related to biliary spasms

A client newly diagnosed with type 1 diabetes has an unusual increase in blood glucose from bedtime to morning. The physician suspects the client is experiencing insulin waning. Based on this diagnosis, the nurse expects which change to the client's medication regimen?

Administering a dose of intermediate-acting insulin before the evening meal

A nurse is caring for a diabetic patient with a diagnosis of nephropathy. What would the nurse expect the urinalysis report to indicate?

Albumin

A client reporting shortness of breath is admitted with a diagnosis of cirrhosis. A nursing assessment reveals an enlarged abdomen with striae, an umbilical hernia, and 4+ pitting edema of the feet and legs. What is the most important data for the nurse to monitor?

Albumin Rationale: With the movement of albumin from the serum to the peritoneal cavity, the osmotic pressure of the serum decreases. This, combined with increased portal pressure, results in movement of fluid into the peritoneal cavity. The low oncotic pressure caused by hypoalbuminemia is a major pathophysiologic factor in the development of ascites and edema.

Which of the following terms describes the involuntary flapping movements of the hands associated with metabolic liver dysfunction?

Asterixis

Which foods should be avoided following acute gallbladder inflammation?

Cheese

A client with calculi in the gallbladder is said to have

A nurse is caring for a client with cholelithiasis. Which sign indicates obstructive jaundice?

Clay-colored stools

The nurse is caring for a client with a history of recurrent episodes of acute pancreatitis. The nurse will anticipate preparing the client for which diagnostic test?

Computed tomography (CT) scan

A preoperative client scheduled to have an open cholecystectomy says to the nurse, "The doctor said that after surgery, I will have a tube in my nose that goes into my stomach. Why do I need that?" What most common reason for a client having a nasogastric tube in place after abdominal surgery should the nurse include in a response?

Decompression

A nurse is planning care for a client in acute addisonian crisis. Which nursing diagnosis should receive the highest priority?

Decreased cardiac output

The nurse is reviewing the laboratory and diagnostic test findings of a client diagnosed with syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following would the nurse expect to find?

Decreased serum osmolarity

Which of the following conditions is most likely to involve a nursing diagnosis of fluid volume deficit?

Pancreatitis

The nurse is caring for a client with diabetes who developed hypoglycemia. What can the nurse administer to the client to raise the blood sugar level?

Glucagon Rationale: Glucagon, a hormone released by alpha islet cells, raises blood sugar levels by stimulating glycogenolysis, the breakdown of glycogen into glucose, in the liver. Insulin is released to lower the blood sugar levels. Cortisone and estrogen are not released from the pancreas.

A client is having chronic pain from arthritis. What type of hormone is released in response to the stress of this pain that suppresses inflammation and helps the body withstand stress?

Glucocorticoids

A client has an elevated serum ammonia concentration and is exhibiting changes in mental status. The nurse should suspect which condition?

Hepatic encephalopathy

A client with acromegaly has been given the option of a surgical approach or a medical approach. The client decides to have a surgical procedure to remove the pituitary gland. What does the nurse understand this surgical procedure is called?

Hypophysectomy

A nurse is assessing a client who is receiving total parenteral nutrition (TPN). Which finding suggests that the client has developed hyperglycemia?

Increased urine output

The nurse is describing the action of insulin in the body to a client newly diagnosed with type 1 diabetes. Which of the following would the nurse explain as being the primary action?

It carries glucose into body cells.

Clinical manifestations of common bile duct obstruction include all of the following except:

Light-colored urine

Measure blood glucose concentration every 4 to 6 hours

The nurse is caring for a client with acute pancreatitis who is admitted to the intensive care unit to monitor for pulmonary complications. What is the nurse's understanding of the pathophysiology of pulmonary complications related to pancreatitis?

Pancreatitis can elevate the diaphragm and alter the breathing pattern.

Which of the following assessments should the nurse perform to determine the development of peptic ulcers when caring for a patient with Cushing's syndrome?

Observe the color of stool.

A client has a blockage of the passage of bile from a stone in the common bile duct. What type of jaundice does the nurse suspect this client has?

Obstructive jaundice

Which liver function study is used to show the size of the liver and hepatic blood flow and obstruction?

Radioisotope liver scan

The nurse is caring for a client with hepatitis. Which of the following would lead the nurse to suspect that the client is in the prodromal phase?

Rash Rationale: During the prodromal or preicteric phase, the following signs and symptoms would be noted: urticaria; nausea; vomiting; anorexia; fever; malaise; arthralgia; headache; right upper quadrant (RUQ) discomfort; enlargement of the spleen, liver, and lymph nodes; weight loss; and rash. Jaundice and clay-colored stools would be characteristic of the icteric phase. Liver function tests returning to normal would be noted in the posticteric phase.

A client with liver cirrhosis develops ascites. Which medication will the nurse prepare teaching for this client?

Spironolactone Rationale: The use of diuretic agents along with sodium restriction is successful in 90% of clients with ascites. Spironolactone, an aldosterone-blocking agent, is most often the first-line therapy in clients with ascites from cirrhosis. When used with other diuretic agents, spironolactone helps prevent potassium loss. Oral diuretic agents such as furosemide may be added but should be used cautiously because long-term use may induce severe hyponatremia (sodium depletion). Acetazolamide and ammonium chloride are contraindicated because of the possibility of precipitating hepatic encephalopathy and coma.

A nurse is caring for a client with cirrhosis. The nurse assesses the client at noon and discovers that the client is difficult to arouse and has an elevated serum ammonia level. The nurse should suspect which situation?

The client's hepatic function is decreasing. Rationale: The decreased level of consciousness caused by an increased serum ammonia level indicates hepatic disfunction. If the client didn't take his morning dose of lactulose, he wouldn't have elevated ammonia levels and decreased level of consciousness this soon. These assessment findings don't indicate that the client is relaxed or avoiding the nurse.

A patient with acute pancreatitis puts the call bell on to tell the nurse about an increase in pain. The nurse observes the patient guarding; the abdomen is board-like and no bowel sounds are detected. What is the major concern for this patient?

The patient has developed peritonitis.

Which medication is used to decrease portal pressure, halting bleeding of esophageal varices?

Vasopressin Rationale: Vasopressin may be the initial therapy for esophageal varices because it constricts the splanchnic arterial bed and decreases portal hypertension. Nitroglycerin has been used to prevent the side effects of vasopressin. Spironolactone and cimetidine do not decrease portal hypertension.

The nurse is administering Cephulac (lactulose) to decrease the ammonia level in a patient who has hepatic encephalopathy. What should the nurse carefully monitor for that may indicate a medication overdose?

Watery diarrhea

When assessing a client with pheochromocytoma, a tumor of the adrenal medulla that secretes excessive catecholamine, the nurse is most likely to detect:

a blood pressure of 176/88 mm Hg. Rationale: Pheochromocytoma causes hypertension, tachycardia, hyperglycemia, hypermetabolism, and weight loss. It isn't associated with hypotension, hypoglycemia, or bradycardia.

A nurse is reviewing the laboratory order for a client suspected of having an endocrine disorder. The lab slip includes obtaining cortisol levels. What is being tested?

adrenal function

Total parental nutrition (TPN) should be used cautiously in clients with pancreatitis because such clients:

cannot tolerate high-glucose concentration.

Which diagnostic test is done to determine suspected pituitary tumor?

computed tomography scan

A client with a 30-year history of type 2 diabetes is having an annual physical and blood work. Which test result would the physician be most concerned with when monitoring the client's treatment compliance?

glycosylated hemoglobin

A client presents with a huge lower jaw, bulging forehead, large hands and feet, and frequent headaches. What could be causing this client's symptoms?

hyperpituitarism

Which instruction should a nurse give to a client with diabetes mellitus when teaching about "sick day rules"?

"Test your blood glucose every 4 hours."

A client is admitted with hyperosmolar hyperglycemic nonketotic syndrome (HHNS). Which laboratory finding should the nurse expect in this client?

Blood glucose level 1,100 mg/dl Rationale: HHNS occurs most frequently in older clients. It can occur in clients with either type 1 or type 2 diabetes mellitus but occurs most commonly in those with type 2. The blood glucose level rises to above 600 mg/dl in response to illness or infection. As the blood glucose level rises, the body attempts to rid itself of the excess glucose by producing urine. Initially, the client produces large quantities of urine. If fluid intake isn't increased at this time, the client becomes dehydrated, causing BUN levels to rise. Arterial pH and plasma bicarbonate levels typically remain within normal limits.

A client's blood glucose level is 45 mg/dl. The nurse should be alert for which signs and symptoms?

Coma, anxiety, confusion, headache, and cool, moist skin Rationale: Signs and symptoms of hypoglycemia (indicated by a blood glucose level of 45 mg/dl) include anxiety, restlessness, headache, irritability, confusion, diaphoresis, cool skin, tremors, coma, and seizures. Kussmaul respirations, dry skin, hypotension, and bradycardia are signs of diabetic ketoacidosis. Excessive thirst, hunger, hypotension, and hypernatremia are symptoms of diabetes insipidus. Polyuria, polydipsia, polyphagia, and weight loss are classic signs and symptoms of diabetes mellitus.

A 70-year-old client is admitted with acute pancreatitis. The nurse understands that the mortality rate associated with acute pancreatitis increases with advanced age and attributes this to which gerontologic consideration associated with the pancreas?

Decreases in the physiologic function of major organs

A physician orders spironolactone (Aldactone), 50 mg by mouth four times daily, for a client with fluid retention caused by cirrhosis. Which finding indicates that the drug is producing a therapeutic effect?

Loss of 2.2 lb (1 kg) in 24 hours Rationale: Daily weight measurement is the most accurate indicator of fluid status; a loss of 2.2 lb (1 kg) indicates loss of 1 L of fluid. Because spironolactone is a diuretic, weight loss is the best indicator of its effectiveness. This client's serum potassium and sodium levels are normal. A blood pH of 7.25 indicates acidosis, an adverse reaction to spironolactone.

On assessment of a patient with early-stage hypothyroidism, the nurse practitioner assesses for a vague yet significant sign which is:

Paresthesia

A client comes to the ED with severe abdominal pain, nausea, and vomiting. The physician plans to rule out acute pancreatitis. The nurse would expect the diagnosis to be confirmed by an elevated result on which laboratory test?

Serum amylase

A client is diagnosed with diabetes mellitus. The client reports visiting the gym regularly and is a vegetarian. Which of the following factors is important to consider when the nurse assesses the client?

The client's consumption of carbohydrates Rationale: While assessing a client, it is important to ask about consumption of carbohydrates due to the client's high blood sugar. Although other factors such as the client's mental and emotional status, history of tests involving iodine, and exercise routine can be part of data collection, they are not the priority when assessing a client with high blood sugar.

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

A client with severe and chronic liver disease is showing manifestations related to inadequate vitamin intake and metabolism. He reports difficulty driving at night because he cannot see well. Which of the following vitamins is most likely deficient for this client?

Vitamin A Rationale: Problems common to clients with severe chronic liver dysfunction result from inadequate intake of sufficient vitamins. Vitamin A deficiency results in night blindness and eye and skin changes. Thiamine deficiency can lead to beriberi, polyneuritis, and Wernicke-Korsakoff psychosis. Riboflavin deficiency results in characteristic skin and mucous membrane lesions. Vitamin K deficiency can cause hypoprothrombinemia, characterized by spontaneous bleeding and ecchymoses.

A nurse is teaching a client about the types of chronic liver disease. The teaching is determined to be effective when the client correctly identifies which type of cirrhosis as being caused by scar tissue surrounding portal areas?

Alcoholic cirrhosis Rationale: Alcoholic cirrhosis, in which the scar tissue characteristically surrounds the portal areas, is most frequently caused by chronic alcoholism and is the most common type of cirrhosis. In postnecrotic cirrhosis, there are broad bands of scar tissue, which are a late result of a previous acute viral hepatitis. In biliary cirrhosis, scarring occurs in the liver around the bile ducts. Compensated cirrhosis is a general term given to the state of liver disease in which the liver continues to be able to function effectively.

A client with acute liver failure exhibits confusion, a declining level of consciousness, and slowed respirations. The nurse finds him very difficult to arouse. The diagnostic information which best explains the client's behavior is:

subnormal serum glucose and elevated serum ammonia levels.

When caring for a client with diabetes insipidus, the nurse expects to administer:

vasopressin
