Final - Acute GI Disorders / Burns

An 80-kg patient with burns over 30% of total body surface area (TBSA) is admitted to the burn unit. Using the Parkland formula of 4 mL/kg/%TBSA, what is the IV infusion rate (mL/hour) for lactated Ringer's solution that the nurse will give during the first 8 hours?

ANS: 600 mL The Parkland formula states that patients should receive 4 mL/kg/%TBSA burned during the first 24 hours. Half of the total volume is given in the first 8 hours and then the remaining half is given over 16 hours: 4 80 30 = 9600 mL total volume; 9600/2 = 4800 mL in the first 8 hours; 4800 mL/8 hr = 600 mL/hr.

A patient arrives in the emergency department with facial and chest burns caused by a house fire. Which action should the nurse take first? a. Auscultate for breath sounds. b. Determine the extent and depth of the burns. c. Give the prescribed hydromorphone (Dilaudid). d. Infuse the prescribed lactated Ringer's solution.

ANS: A A patient with facial and chest burns is at risk for inhalation injury and assessment of airway and breathing is the priority. The other actions will be completed after airway management is assured

Which laboratory test result will the nurse monitor to evaluate the effects of therapy for a patient who has acute pancreatitis? a. Lipase b. Calcium c. Bilirubin d. Potassium

ANS: A Lipase is elevated in acute pancreatitis. Although changes in the other values may occur, they would not be useful in evaluating whether the prescribed therapies have been effective.

The charge nurse observes the following actions being taken by a new nurse on the burn unit. Which action by the new nurse would require immediate intervention by the charge nurse? a. The new nurse uses clean gloves when applying antibacterial cream to a burn wound. b. The new nurse obtains burn cultures when the patient has a temperature of 95.2° F (35.1° C). c. The new nurse gives PRN fentanyl (Sublimaze) IV to a patient 5 minutes before a dressing change. d. The new nurse calls the health care provider when a nondiabetic patient's serum glucose is elevated.

ANS: A Sterile gloves should be worn when applying medications or dressings to a burn. Hypothermia is an indicator of possible sepsis, and cultures are appropriate. Nondiabetic patients may need insulin because stress and high-calorie intake may lead to temporary hyperglycemia. Fentanyl peaks 5 minutes after IV administration and should be used just before and during dressing changes for pain management.

An employee spills industrial acid on both arms and legs at work. What action should the occupational health nurse take? a. Remove nonadherent clothing and wristwatch. b. Apply an alkaline solution to the affected area. c. Place a cool compress on the area of exposure. d. Cover the affected area with dry, sterile dressings.

ANS: A With chemical burns, the first action is to remove the chemical from contact with the skin as quickly as possible. Remove nonadherent clothing, shoes, watches, jewelry, glasses, or contact lenses (if the face was exposed). Flush the chemical from the wound and surrounding area with copious amounts of saline solution or water. Covering the affected area or placing cool compresses on the area will leave the chemical in contact with the skin. Application of an alkaline solution can cause more injury.

Which patient should the nurse assess first after receiving change-of-shift report? a. A 30-yr-old patient who has a distended abdomen and tachycardia b. A 60-yr-old patient whose ileostomy has drained 800 mL over 8 hours c. A 40-yr-old patient with ulcerative colitis who had six liquid stools in 4 hours d. A 50-yr-old patient with familial adenomatous polyposis who has occult blood in the stool

ANS: A The patient's abdominal distention and tachycardia suggest hypovolemic shock caused by problems such as peritonitis or intestinal obstruction, which will require rapid intervention. The other patients should be assessed as quickly as possible, but the data do not indicate any life-threatening complications associated with their diagnoses

A patient is awaiting surgery for acute peritonitis. Which action will the nurse plan to include in the preoperative care? a. Position patient with the knees flexed. b. Avoid use of opioids or sedative drugs. c. Offer frequent small sips of clear liquids. d. Assist patient to breathe deeply and cough.

ANS: A There is less peritoneal irritation with the knees flexed, which will help decrease pain. Opioids and sedatives are typically given to control pain and anxiety. Preoperative patients with peritonitis are given IV fluids for hydration. Deep breathing and coughing will increase the patient's discomfort.

What risk factor will the nurse specifically ask about when a patient is being admitted with acute pancreatitis? a. Diabetes b. Alcohol use c. High-protein diet d. Cigarette smoking

ANS: B Alcohol use is one of the most common risk factors for pancreatitis in the United States. Cigarette smoking, diabetes, and high-protein diets are not risk factors.

A patient reports gas pains and abdominal distention 2 days after a small bowel resection. Which nursing action should the nurse take? a. Administer morphine sulfate. b. Encourage the patient to ambulate. c. Offer the prescribed promethazine. d. Instill a mineral oil retention enema.

ANS: B Ambulation will improve peristalsis and help the patient eliminate flatus and reduce gas pain. A mineral oil retention enema is helpful for constipation with hard stool. A return-flow enema might be used to relieve persistent gas pains. Morphine will further reduce peristalsis. Promethazine is used as an antiemetic rather than to decrease gas pains or distention.

A patient has just been admitted with a 40% total body surface area (TBSA) burn injury. To maintain adequate nutrition, the nurse should plan to take which action? a. Administer vitamins and minerals intravenously. b. Insert a feeding tube and initiate enteral nutrition. c. Infuse total parenteral nutrition via a central catheter. d. Encourage an oral intake of at least 5000 kcal per day.

ANS: B Enteral nutrition can usually be started during the emergent phase at low rates and increased over 24 to 48 hours to the goal rate. During the emergent phase, the patient will be unable to eat enough calories to meet nutritional needs and may have a paralytic ileus that prevents adequate nutrient absorption. Vitamins and minerals may be given during the emergent phase, but these will not assist in meeting the patient's caloric needs. Parenteral nutrition increases the infection risk, does not help preserve gastrointestinal function, and is not routinely used in burn patients unless the gastrointestinal tract is not available for use.

A 74-yr-old male patient tells the nurse that growing old causes constipation, so he has been using a suppository to prevent constipation every morning. Which action should the nurse take first? a. Encourage the patient to increase oral fluid intake. b. Question the patient about risk factors for constipation. c. Suggest that the patient increase intake of high-fiber foods. d. Teach the patient that a daily bowel movement is unnecessary.

ANS: B The nurse's initial action should be further assessment of the patient for risk factors for constipation and for his usual bowel pattern. The other actions may be appropriate but will be based on the assessment.

Which patient should the nurse assess first? a. A patient with burns who reports a level 8 (0 to 10 scale) pain. b. A patient with smoke inhalation who has wheezes and altered mental status. c. A patient with full-thickness leg burns who is scheduled for a dressing change. d. A patient with partial thickness burns who is receiving IV fluids at 500 mL/hr

ANS: B This patient has evidence of lower airway injury and hypoxemia and should be assessed at once to determine the need for O2 or intubation (or both). The other patients should be assessed as rapidly as possible, but they do not have evidence of life-threatening complications.

A patient with extensive electrical burn injuries is admitted to the emergency department. Which prescribed intervention should the nurse implement first? a. Assess pain level. b. Place on heart monitor. c. Check potassium level. d. Assess oral temperature.

ANS: B After an electrical burn, the patient is at risk for life-threatening dysrhythmias and should be placed on a heart monitor. Assessing the oral temperature and pain is not as important as assessing for dysrhythmias. Checking the potassium level is important, but it will take time before the laboratory results are back. The first intervention is to place the patient on a heart monitor and assess for dysrhythmias so that they can be monitored and treated if necessary.

The nurse is planning care for a patient with acute severe pancreatitis. What is the highest priority patient outcome? a. Having fluid and electrolyte balance b. Maintaining normal respiratory function c. Expressing satisfaction with pain control d. Developing no ongoing pancreatic disease

ANS: B Respiratory failure can occur as a complication of acute pancreatitis and maintenance of adequate respiratory function is the priority goal. The other outcomes would also be appropriate for the patient.

A patient with circumferential burns of both legs develops a decrease in dorsalis pedis pulse strength and numbness in the toes. Which action should the nurse take first? a. Monitor the pulses every hour. b. Notify the health care provider. c. Elevate both legs above heart level with pillows. d. Encourage the patient to flex and extend the toes

ANS: B The decrease in pulse and numbness in a patient with circumferential burns shows decreased circulation to the legs and the need for an escharotomy. Monitoring the pulses is not an adequate response to the decrease in circulation. Elevating the legs or increasing toe movement will not improve the patient's circulation.

A patient is admitted to the burn unit with burns to the head, face, and hands. Initially, wheezes are heard, but an hour later, the lung sounds are decreased, and no wheezes are audible. What action should the nurse take? a. Encourage the patient to cough and auscultate the lungs again. b. Notify the health care provider and prepare for endotracheal intubation. c. Document the results and continue to monitor the patient's respiratory rate. d. Reposition the patient in high-Fowler's position and reassess breath sounds.

ANS: B The patient's history and clinical manifestations suggest airway edema, and the health care provider should be notified at once so that intubation can be done rapidly. Placing the patient in a more upright position or having the patient cough will not address the problem of airway edema. Continuing to monitor is inappropriate because immediate action should occur.

A patient admitted with burns over 30% of the body surface 2 days ago now has dramatically increased urine output. Which action should the nurse plan to support maintaining kidney function? a. Monitoring white blood cells (WBCs). b. Continuing to measure the urine output. c. Assessing that blisters and edema have subsided. d. Encouraging the patient to eat adequate calories.

ANS: B The patient's urine output indicates that the patient is entering the acute phase of the burn injury and moving on from the emergent stage. At the end of the emergent phase, capillary permeability normalizes, and the patient begins to diurese large amounts of urine with a low specific gravity. Although this may occur at about 48 hours, it may be longer in some patients. Blisters and edema begin to resolve, but this process requires more time. WBCs may increase or decrease, based on the patient's immune status and any infectious processes. The WBC count does not indicate kidney function. Although adequate nutrition is important for healing, it does not ensure adequate kidney functioning

Eight hours after a thermal burn covering 50% of a patient's total body surface area (TBSA), the nurse assesses the patient. The patient weighs 92 kg (202.4 lb). Which information would be a priority to communicate to the health care provider? a. Blood pressure is 95/48 per arterial line. b. Urine output of 41 mL over past 2 hours. c. Serous exudate is leaking from the burns. d. Heart monitor shows sinus tachycardia of 108.

ANS: B The urine output should be at least 0.5 to 1.0 mL/kg/hr during the emergent phase, when the patient is at great risk for hypovolemic shock. The nurse should notify the health care provider because a higher IV fluid rate is needed. BP during the emergent phase should be greater than 90 mm Hg systolic and the pulse rate should be less than 120 beats/min. Serous exudate from the burns is expected during the emergent phase.

A young adult patient who is in the rehabilitation phase 6 months after a severe face and neck burn tells the nurse, "I'm sorry that I'm still alive. My life will never be normal again." Which response should the nurse make? a. "Most people recover after a burn and feel satisfied with their lives." b. "It's true that your life may be different. What concerns you the most?" c. "Why do you feel that way? It will get better as your recovery progresses." d. "It is really too early to know how much your life will be changed by the burn."

ANS: B This response acknowledges the patient's feelings and asks for more assessment data that will help in developing an appropriate plan of care to assist the patient with the emotional response to the burn injury. The other statements are accurate but do not acknowledge the anxiety and depression that the patient is expressing.

When assessing a patient who spilled hot oil on the right leg and foot, the nurse notes dry, pale, and hard skin. The patient states that the burn is not painful. What term would the nurse use to document the burn depth? a. First-degree skin destruction b. Full-thickness skin destruction c. Deep partial-thickness skin destruction d. Superficial partial-thickness skin destruction

ANS: B With full-thickness skin destruction, the appearance is pale and dry or leathery, and the area is painless because of the associated nerve destruction. Erythema, swelling, and blisters point to a deep partial-thickness burn. With superficial partial-thickness burns, the area is red, but no blisters are present. First-degree burns exhibit erythema, blanching, and pain.

Which assessment finding would the nurse need to report most quickly to the health care provider regarding a patient who has acute pancreatitis? a. Nausea and vomiting b. Hypotonic bowel sounds c. Muscle twitching and finger numbness d. Upper abdominal tenderness and guarding

ANS: C Muscle twitching and finger numbness indicate hypocalcemia, which may lead to tetany unless calcium gluconate is administered. Although the other findings should also be reported to the health care provider, they do not indicate complications that require rapid action.

When taking the blood pressure (BP) on the right arm of a patient who has severe acute pancreatitis, the nurse notices carpal spasms of the patient's right hand. Which action should the nurse take next? a. Ask the patient about any arm pain. b. Retake the patient's blood pressure. c. Check the calcium level in the chart. d. Notify the health care provider immediately.

ANS: C The patient with acute pancreatitis is at risk for hypocalcemia, and the assessment data indicate a positive Trousseau's sign. The health care provider should be notified after the nurse checks the patient's calcium level. There is no indication that the patient needs to have the BP rechecked or that there is any arm pain.

A patient with burns covering 40% total body surface area (TBSA) is in the acute phase of burn treatment. Which snack would be best for the nurse to offer to this patient? a. Bananas b. Orange gelatin c. Vanilla milkshake d. Whole grain bagel

ANS: C A patient with a burn injury needs high-protein and high-calorie food intake, and the milkshake is the highest in these nutrients. The other choices are not as nutrient dense as the milkshake. Gelatin is likely high in sugar. The bagel is a good carbohydrate choice but low in protein. Bananas are a good source of potassium but are not high in protein and calories

A patient has just arrived in the emergency department after an electrical burn from exposure to a high-voltage current. What is the priority nursing assessment? a. Oral temperature b. Peripheral pulses c. Extremity movement d. Pupil reaction to light

ANS: C All patients with electrical burns should be considered at risk for cervical spine injury, and assessment of extremity movement will provide baseline data. The other assessment data are necessary but not as essential as determining the cervical spine status.

Which nursing action is a priority for a patient who has suffered a burn injury while working on an electrical power line? a. Inspect the contact burns. b. Check the blood pressure. c. Stabilize the cervical spine. d. Assess alertness and orientation.

ANS: C Cervical spine injuries are often associated with electrical burns. Therefore, stabilization of the cervical spine takes precedence after airway management. The other actions are also included in the emergent care after electrical burns, but the most important action is to avoid spinal cord injury.

Esomeprazole is prescribed for a patient who incurred extensive burn injuries 5 days ago. Which nursing assessment would best evaluate the effectiveness of the drug? a. Bowel sounds b. Stool frequency c. Stool occult blood d. Abdominal distention

ANS: C H2 blockers and proton pump inhibitors are given to prevent Curling's ulcer in the patient who has sustained burn injuries. Proton pump inhibitors usually do not affect bowel sounds, stool frequency, or appetite.

A patient with severe burns has crystalloid fluid replacement ordered using the Parkland formula. The initial volume of fluid to be given in the first 24 hours is 30,000 mL. The initial rate of administration is 1875 mL/hr. After the first 8 hours, what rate should the nurse infuse the IV fluids? a. 219 mL/hr b. 625 mL/hr c. 938 mL/hr d. 1875 mL/hr

ANS: C Half of the fluid replacement using the Parkland formula is administered in the first 8 hours and the other half over the next 16 hours. In this case, the patient should receive half of the initial rate, or 938 mL/hr.

The nurse is reviewing laboratory results on a patient who had a large burn 48 hours ago. Which result requires priority action by the nurse? a. Hematocrit of 53% b. Serum sodium of 147 mEq/L c. Serum potassium of 6.1 mEq/L d. Blood urea nitrogen of 37 mg/dL

ANS: C Hyperkalemia can lead to life-threatening dysrhythmias. The patient needs cardiac monitoring and immediate treatment to lower the potassium level. The other laboratory values are also abnormal and require changes in treatment, but they are not as immediately life threatening as the elevated potassium level.

A patient who was found unconscious in a burning house is brought to the emergency department by ambulance. The nurse notes that the patient's skin color is bright red. Which action should the nurse take first? a. Insert two large-bore IV lines. b. Check the patient's orientation. c. Place the patient on 100% O2 using a nonrebreather mask. d. Assess for singed nasal hair and dark oral mucous membranes.

ANS: C The patient's history and skin color suggest carbon monoxide poisoning, which should be treated by rapidly starting O2 at 100%. The other actions can be taken after the action to correct gas exchange.

A patient in the emergency department has just been diagnosed with peritonitis from a ruptured diverticulum. Which prescribed intervention will the nurse implement first? a. Send the patient for a CT scan. b. Insert a urinary catheter to drainage. c. Infuse metronidazole (Flagyl) 500 mg IV. d. Place a nasogastric tube to intermittent low suction.

ANS: C Because peritonitis can be fatal if treatment is delayed, the initial action should be to start antibiotic therapy (after any ordered cultures are obtained). The other actions can be done after antibiotic therapy is initiated.

A patient who has chronic constipation asks the nurse about the use of psyllium (Metamucil). Which information will the nurse include in the response? a. Fiber-containing laxatives may reduce the absorption of fat-soluble vitamins. b. Dietary sources of fiber should be eliminated to prevent excessive gas formation. c. Use of this type of laxative to prevent constipation does not cause adverse effects. d. Large amounts of fluid should be taken to prevent impaction or bowel obstruction.

ANS: D A high fluid intake is needed when patients are using bulk-forming laxatives to avoid worsening constipation. Although bulk-forming laxatives are generally safe, the nurse should emphasize the possibility of constipation or obstipation if inadequate fluid intake occurs. Although increased gas formation is likely to occur with increased dietary fiber, the patient should gradually increase dietary fiber and eventually may not need the psyllium. Fat-soluble vitamin absorption is blocked by stool softeners and lubricants, not by bulk-forming laxatives.

Which prescribed drug is best for the nurse to give before scheduled wound debridement on a patient with partial-thickness burns? a. ketorolac b. lorazepam (Ativan) c. gabapentin (Neurontin) d. hydromorphone (Dilaudid)

ANS: D Opioid pain medications are the best choice for pain control. The other drugs are used as adjuvants to enhance the effects of opioids.

A patient who has burns on the arms, legs, and chest from a house fire has become agitated and restless 8 hours after being admitted to the hospital. Which action should the nurse take first? a. Stay at the bedside and reassure the patient. b. Administer the ordered morphine sulfate IV. c. Assess orientation and level of consciousness. d. Use pulse oximetry to check oxygen saturation

ANS: D Agitation in a patient who may have suffered inhalation injury might indicate hypoxia, and this should be assessed by the nurse first. Administration of morphine may be indicated if the nurse determines that the agitation is caused by pain. Assessing level of consciousness and orientation is appropriate but not as essential as determining whether the patient is hypoxemic. Reassurance is not helpful to reduce agitation in a hypoxemic patient.

Which action will the nurse include in the plan of care for a patient in the rehabilitation phase after a burn injury to the right arm and chest? a. Keep the right arm in a position of comfort. b. Avoid the use of sustained-release narcotics. c. Teach about the purpose of tetanus immunization. d. Apply water-based cream to burned areas frequently

ANS: D Application of water-based emollients will moisturize new skin and decrease flakiness and itching. To avoid contractures, the joints of the right arm should be positioned in an extended position, which is not the position of comfort. Patients may need to continue the use of opioids during rehabilitation. Tetanus immunization would have been given during the emergent phase of the burn injury.

During the emergent phase of burn care, which assessment is most useful in determining whether the patient is receiving adequate fluid infusion? a. Check skin turgor. b. Monitor daily weight. c. Assess mucous membranes. d. Measure hourly urine output.

ANS: D When fluid intake is adequate, the urine output will be at least 0.5 to 1 mL/kg/hr. The patient's weight is not useful in this situation because of the effects of third spacing and evaporative fluid loss. Mucous membrane assessment and skin turgor also may be used, but they are not as adequate in determining that fluid infusions are maintaining adequate perfusion

Which assessment finding is of most concern for a patient with acute pancreatitis? a. Absent bowel sounds b. Abdominal tenderness c. Left upper quadrant pain d. Palpable abdominal mass

ANS: D A palpable abdominal mass may indicate the presence of a pancreatic abscess, which will require rapid surgical drainage to prevent sepsis. Absent bowel sounds, abdominal tenderness, and left upper quadrant pain are common in acute pancreatitis and do not require rapid action to prevent further complications.

What is a likely finding in the nurse's assessment of a patient who has a large bowel obstruction? a. Referred back pain b. Metabolic alkalosis c. Projectile vomiting d. Abdominal distention

ANS: D Abdominal distention is seen in lower intestinal obstruction. Referred back pain is not a common clinical manifestation of intestinal obstruction. Metabolic alkalosis is common in high intestinal obstruction because of the loss of HCl acid from vomiting. Projectile vomiting is associated with higher intestinal obstruction.

A patient with acute pancreatitis is NPO and has a nasogastric (NG) tube to suction. Which information obtained by the nurse indicates that these therapies have been effective? a. Bowel sounds are present. b. Grey Turner sign resolves. c. Electrolyte levels are normal. d. Abdominal pain is decreased.

ANS: D NG suction and NPO status will decrease the release of pancreatic enzymes into the pancreas and decrease pain. Although bowel sounds may be hypotonic with acute pancreatitis, the presence of bowel sounds does not indicate that treatment with NG suction and NPO status has been effective. Electrolyte levels may be abnormal with NG suction and must be replaced by appropriate IV infusion. Although Grey Turner sign will eventually resolve, it would not be appropriate to wait for this to occur to determine whether treatment was effective.

A nurse is considering which patient to admit to the same room as a patient who is hospitalized with acute rejection 3 weeks after a liver transplant. Which patient would be the best choice? a. Patient who is receiving chemotherapy for liver cancer b. Patient who is receiving treatment for acute hepatitis C c. Patient who has a wound infection after cholecystectomy d. Patient who requires pain management for chronic pancreatitis

ANS: D The patient with chronic pancreatitis does not present an infection risk to the immunosuppressed patient who had a liver transplant. The other patients either are at risk for infection or currently have an infection, which will place the immunosuppressed patient at risk for infection.
