ESOPHAGEAL VARICES

To detect possible complications in a patient with severe cirrhosis who has bleeding esophageal varices, it is most important for the nurse to monitor a. bilirubin levels. b. ammonia levels. c. potassium levels. d. prothrombin time.

ANS B The protein in the blood in the gastrointestinal (GI) tract will be absorbed and may result in an increase in the ammonia level because the liver cannot metabolize protein very well. The prothrombin time, bilirubin, and potassium levels should also be monitored, but they will not be affected by the bleeding episode.

During the admission assessment of a client with a history of alcohol abuse for diagnosis of ruptured esophageal varices, the client says, "I deserve this. I brought it on myself." Which response is most therapeutic for the nurse to make to the client? 1. "Would you like to talk to the chaplain?" 2. "Is there some reason you feel you deserve this?" 3. "Not all esophageal varices are caused by alcohol." 4. "That is something to think about when you leave the hospital."

ANS: 2 Rationale: Ruptured esophageal varices are often a complication of cirrhosis of the liver, and the most common type of cirrhosis is caused by chronic alcohol abuse. It is important to obtain an accurate history regarding the client's alcohol intake. If the client is ashamed or embarrassed, he or she may not respond accurately. Option 2 is open-ended and allows the client to discuss his or her feelings about drinking. Option 1 blocks the nurse-client communication process. Options 3 and 4 are somewhat judgmental. Priority Nursing Tip: Rupture and resultant hemorrhage of the esophageal varices are primary concerns because this is a life-threatening situation. Test- Taking Strategy: Note the strategic word, most. Use therapeutic communication techniques to direct you to the correct option. Remember that the client's feelings should be addressed first.

A patient is admitted with a gastrointestinal hemorrhage due to esophagogastric varices. The nurse knows that varices are caused by which pathophysiologic mechanism? a. Portal hypertension 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 the mucosal resistance d. Inflammation and ulceration secondary to nonsteroidal antiinflammatory drug use

ANS: 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 with a history of cirrhosis is admitted to the ICU with a diagnosis of bleeding esophageal varices; an attempt to stop the bleeding has been only partially successful. What would the critical care nurse expect the care team to order for this patient? A) Packed red blood cells (PRBCs) B) Vitamin K C) Oral anticoagulants D) Heparin infusion

ANS: A Patients with liver dysfunction may have life-threatening hemorrhage from peptic ulcers or esophageal varices. In these cases, replacement with fresh frozen plasma, PRBCs, and platelets is usually required. Vitamin K may be ordered once the bleeding is stopped, but that is not what is needed to stop the bleeding of the varices. Anticoagulants would exacerbate the patients bleeding.

A patient is admitted with a gastrointestinal hemorrhage due to esophagogastric varices. What medication would the nurse expect the practitioner to order for this patient? a. Histamine2 (H2) antagonists b. Vasopressin c. Heparin d. Antacids

ANS: 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 with a diagnosis of esophageal varices has undergone endoscopy to gauge the progression of this complication of liver disease. Following the completion of this diagnostic test, what nursing intervention should the nurse perform? A) Keep patient NPO until the results of test are known. B) Keep patient NPO until the patients gag reflex returns. C) Administer analgesia until post-procedure tenderness is relieved. D) Give the patient a cold beverage to promote swallowing ability

ANS: B After the examination, fluids are not given until the patients gag reflex returns. Lozenges and gargles may be used to relieve throat discomfort if the patients physical condition and mental status permit. The result of the test is known immediately. Food and fluids are contraindicated until the gag reflex returns

A nurse is caring for a patient who has been admitted for the treatment of advanced cirrhosis. What assessment should the nurse prioritize in this patients plan of care? A) Measurement of abdominal girth and body weight B) Assessment for variceal bleeding C) Assessment for signs and symptoms of jaundice D) Monitoring of results of liver function testing

ANS: B Esophageal varices are a major cause of mortality in patients with uncompensated cirrhosis. Consequently, this should be a focus of the nurses assessments and should be prioritized over the other listed assessments, even though each should be performed.

Which patient should the nurse assess first after receiving change-of-shift report? a. A patient with nausea who has a dose of metoclopramide (Reglan) due b. A patient who is crying after receiving a diagnosis of esophageal cancer c. A patient with esophageal varices who has a blood pressure of 92/58 mm Hg d. A patient admitted yesterday with gastrointestinal (GI) bleeding who has melena

ANS: C The patients history and blood pressure indicate possible hemodynamic instability caused by GI bleeding. The data about the other patients do not indicate acutely life-threatening complications.

The most common single cause of death in patients with cirrhosis is: a. congestive heart failure. b. hepatic encephalopathy. c. hypovolemic shock. d. ruptured esophageal varices.

ANS: D

4. A nurse cares for a client who is hemorrhaging from bleeding esophageal varices and has an esophagogastric tube. Which action should the nurse take first? a. Sedate the client to prevent tube dislodgement. b. Maintain balloon pressure at 15 and 20 mm Hg. c. Irrigate the gastric lumen with normal saline. d. Assess the client for airway patency.

ANS: D Maintaining airway patency is the primary nursing intervention for this client. The nurse suctions oral secretions to prevent aspiration and occlusion of the airway. The client usually is intubated and mechanically ventilated during this treatment. The client should be sedated, balloon pressure should be maintained between 15 and 20 mm Hg, and the lumen can be irrigated with saline or tap water. However, these are not a higher priority than airway patency.

A nurse assesses a client who is prescribed an infusion of vasopressin (Pitressin) for bleeding esophageal varices. Which clinical manifestation should alert the nurse to a serious adverse effect? a. Nausea and vomiting b. Frontal headache c. Vertigo and syncope d. Mid-sternal chest pain

ANS: D Mid-sternal chest pain is indicative of acute angina or myocardial infarction, which can be precipitated by vasopressin. Nausea and vomiting, headache, and vertigo and syncope are not side effects of vasopressin
