Metabolism Rapid Reasoning NURS 2900 10 Points III. Developing Nurse Thinking by Identifying Clinical RELATIONSHIPS What is the RELATIONSHIP of the past medical history and current illness? 1 Point Past Medical History: Current Illness: Patient is a 27-year-old male who immigrated to America from Somalia and is currently living in New York. His past medical history relates to his current illness for several reasons. Patient is unable to identify his medical history or treatment, He states he had a liver problem where he was hospitalized, and it was viral in nature. He does not recall the treatment. He chews khat which is a caffeinated chew that could be related to the poor dentition as well as poor nutrition and limited access to resources. He denies the use of alcohol or other drugs. He has a history of taking ibuprofen and Tylenol for joint paint. He was previously healthy with no other symptoms. He has a history of smoking 1 pack per day since he was a teenager It should be noted there is a potential that the patient has been walking around with a hepatitis virus and because he has been asymptomatic as evidenced by previous statement of healthy until recently, he has not been aware that he is still carrying the virus. © 2014 Keith Rischer/www.KeithRN.com 1. He grew up and immigrated he from a country that is underdeveloped and lacking in resources especially for health care. Hepatitis vaccination rates are lower in other countries that have poor medical care. 2. He does not have a good understanding of his medical history. He is unable to identify whether he had treatment or not or what his illness is even called. This is relevant currently because it indicates he still has significant barriers to accessing medicine for one reason or another. His inability to recall information could also potentially be correlated to a decrease in level of awareness. Knowing that he was hospitalized one year ago helps indicate a level of chronicity of the disease etiology. 3. If he had received treatment and continued education about his illness, he could have potentially mitigated his disease progression and lived a more full and normal life. if the patient has hepatitis b he could have been walking around with it from the time of birth unaware minus the one prior sickness from it. 4. He does not have a history of alcohol or drug use which indicates that again this is not necessarily caused by needles although he could have been nicked or scraped by someone infected. It is more liable that he contracted it either through birth or blood contamination through poor sanitary living conditions. Metabolism Rapid Reasoning NURS 2900 10 Points What is the RELATIONSHIP between each physician order and Abdi’s problem? 2.5 Points Care Provider Orders: 1. Seizure precautions 2. Esophagogastroduodenoscopy (EGD) with Biopsy 3. Neurological assessment Q2 hours 4. Daily Weight 5. Paracentesis 6. Bed rest 7. Dietician consult List 3 best practice screenings that you will implement and why Rationale for why the primary care provider ordered this? 1.Seizure precautions are put into place because the patient is developing hepatic encephalopathy. Studies vary on the proportion of patients that develop seizures due to hepatic encephalopathy some studies suggest it is an uncommon event and others suggest approximately 1/3 of patients with liver failure and hepatic encephalopathy will develop seizures. The development of seizure due to hepatic encephalopathy is increased poor outcomes. because little is known about this patient’s medical history and because of the severity of his cirrhosis/liver failure he should be put on seizure precautions as a standard safety protocol. 2. Esophagogastroduodenoscopy (EGD) is a diagnostic endoscopic procedure used to visualize the oropharynx, esophagus, stomach, and proximal duodenum. The purpose of this procedure is to detect the presence of esophageal varices, ulcerations of the stomach, duodenal ulcers and bleeding. The EDG is considered a lower risk procedure for patients with liver failure. 3. Neuro checks every two hours are indicated for patients displaying signs of hepatic encephalopathy. The patient is exhibiting signs of lowered consciousness, as well as asterixis, coupled with high levels of ammonia in the blood. Excess ammonia in the blod stream results in increased glutamine production and accumulation in astrocytes. This creates an osmotic gradient that promotes (brain cells) astrocytic swelling Elevated glutamine levels also result in a process that contributes to the neuronal dysfunction in hepatic encephalopathy. These processes facilitated ammonia crossing the blood brain barrier and cause cerebral edema. Neuro checks are required to monitor for progression because without monitoring neurological function in the presence of excess ammonia the patient will ultimately end up in a coma and die, through organ failure. 4. daily weights are necessary currently because the patient is retaining fluid. He has peripheral edema, he has ascites in his abdomen, his sodium levels are elevated, potassium levels are low and he is oliguric, and displaying all indications of hepatorenal syndrome. 5.Paracentesis is indicated in patients with later stages of cirrhosis, liver failure, the goal is to remove fluid off the belly and relieve the ascites, the fluid removed can also be measures, and sent to the lab to look for infection. With ascites © 2014 Keith Rischer/www.KeithRN.com Metabolism Rapid Reasoning NURS 2900 10 Points 6.Bed rest should be prescribed for him due to the increasing cerebral edema, or hepatic encephalopathy. He is hypotensive and has lowered level of consciousness so the safest thing for him to do is just rest and not try to get up. 7.needs a dietary consult to determine what he should be eating and discuss how to get nutrients adequately. He is now having issues with both his liver and his kidneys and will need a low sodium diet, with the appropriate amount of protein for where his liver and kidney function are at. Three best practice screenings for him would be Fall risk: he should be on falls precautions due to hypotension and increased icp. Nursing Delirium scale or Neecham confusion scale to measure Delirium is considered as an altered mental state, which is somewhere between between coma and stupor at one end and normal wakefulness and alertness at the other. This is indicated for patients with hepatic encephalopathy. Pain scale : he should be on a pain scale because elevated pain increases blood pressure which can elevate intracranial pressure. Glasgow coma scale: he should have the Glasgow comas scale being utilized each shift or assessment due to the hepatic encephalopathy. This will allow them to monitor his level or consciousness and neurological functioning and correlate to other findings. What is the rationale for why each of the medications are being administered? 1.5 Points © 2014 Keith Rischer/www.KeithRN.com Metabolism Rapid Reasoning NURS 2900 10 Points Medication Orders: Lactulose 10 g/15 mL Solution- Administer 30 mL orally TID Lansoprazole 30 mg tablet- Administer 1 tablet orally AC BID Potassium Replacement Protocol Lasix 20 mg tablet- Administer 1 tablet orally BID Spironolactone 12.5 mg tablet- Administer orally Daily Propranolol 20 mg tablet- Administer 1 tablet orally TID Rationale: Lactulose is used to prevent and treat clinical portalsystemic encephalopathy it acts to decrease the intestinal production and absorption of ammonia. Lactulose catalyzes increases in uptake of ammonia by bacteria found in the colon. The bacteria utilize the trapped ammonia as a nitrogen source for protein synthesis. This causes a decrease in the intestinal ph. which allows the conversion of NH3 to NH4+ the ionized form of ammonium is unable to cross the blood brain barrier thereby inhibiting the continued development of hepatic encephalopathy. Lactulose also decreases the production of ammonia in the intestines by destroying the bacteria responsible for the production of ammonia. Lansoprazole selectively inhibits membrane enzymes in gastric parietal cells and reducing gastric acid secretion. It is effective at treating acid secretions in the stomach and esophagus. This is important because the patient has coagulation problems currently and is at an increased risk of esophageal varices or bleeding. Potassium replacement protocol the potassium replacement protocol is indicated because he has a low potassium level currently at 2.9 and he is going to be taking Lasix and undergoing a paracentesis. All of these factors are going to put his fluid and electrolyte status at greater risk. He is also having little urine output and hepatorenal syndrome. when he beings to urinate the fluid out he will need to have his potassium levels monitored closely Lasix: the furosemide is high ceiling loop diuretic that acts at the distal loops of Henle to block the absorption of sodium and water from the filtered fluid in the kidneys. Water follows sodium and to potassium follows sodium. Spironolactone is prescribed in combination with Lasix to diurese the patient more effectively this is a common prescription for causing an increased diuretic effect and it is potassium sparing to hopefully preserve some of the potassium that will be lost due to the Lasix. Propranolol is a non-selective beta blocker that is readily prescribed for the treatment of esophageal varices and portal hypertension. propranolol works by reducing the hepatic venous pressure and decreasing it to below 12mmHG leads to a reduction in the risk of variceal bleeding. © 2014 Keith Rischer/www.KeithRN.com Metabolism Rapid Reasoning NURS 2900 10 Points What is the priority problem (Diagnosis) that your patient is most likely presenting with? 0.5 Point Acute liver failure which could be leading to cirrhosis or end stage liver disease. This is most likely secondary to a hepatitis infection that remained in the body latent and had an acute onset. It would be difficult to conclude that he does in fact have end stage liver disease without a biopsy and several other diagnostic labs used to verify cirrhosis. What is the underlying cause/pathophysiology of this primary problem? 0.5 Point Viral hepatitis------- infection causes the host to mount a response against viral proteins that are expressed by infected hepatocytes. This process proliferates and creates a cascade where pro- apoptosis (death) t cells recognize antigen on hepatocytes and triggers an inflammatory necrotizing disease pathway. This can be chronic or acute depending on the type and the bodies immune response. In the case of this patient, he developed acute potentially on chronic liver failure (some people can have hepatitis chronically and be asymptomatic unaware). Viral Hepatitis especially B in this patients case can leave a patient asymptomatic for years and then develop fulminant liver failure or acute liver failure. ---Acute liver failure: - this is caused by proinflammatory viral response that destroys a significant number of hepatocytes. The hepatocytes are replaced by a fibrous tissue which are then unable to function and serve the purposes of a functioning liver. – this leads to cirrhosis which is end stage liver failure. There are several system issues that occur to facilitate acute liver failure and make it worse. A significant amount of blood is being circulated through the liver at any given time for detoxification and other processes. The destruction of hepatocytes leads to fibrosis of the liver. The changes in structure of the liver caused by the destruction of hepatocytes cause an increase in the vascular resistance in the liver which causes portal hypertension. The increase in portal pressure decreases the blood flow in the portal system causing blood to shunted and enter into the splenic circulation overall (gi circulation). The body tries to compensate by and dilating the blood vessels which leads to pooling of platelets being sequestered into the spleen. (splenomegaly). This with poor protein blood levels (low albumin) leads to poor © 2014 Keith Rischer/www.KeithRN.com Metabolism Rapid Reasoning NURS 2900 10 Points perfusion of renal system and the RASS system activates and fluid is retained. This process leads to thrombocytopenia, anemia, leukopenia, as well as initiates the hepatorenal syndrome. The vasodilation that occurs in gi or splanchnic circulation along with the decreased blood flow the portal system causes the blood to pool which creates a hypovolemic effect in the central circulatory system. This causes the sympathetic nervous system to respond inappropriately to angiotensin II leading to worsened blood pressures. The complexity of the circulatory dysregulation leads to a prerenal injury of the kidney. This process is proliferated by the continuous shunting of blood due to portal hypertension. Increased intra-abdominal pressure can cause venous congestion and a decline in GFR. In addition, organ compression can stimulate the RAAS system as well. Bilirubin which is the end product of heme is converted i to urobilinogen and excreted from the body when this process is disrupted patients develop jaundice. Ammonia is another ion that builds up in the body, ammonia is the byproduct of gluconeogenesis in protein synthesis. However, ammonia builds up due to the shunting that occurs in the liver and is not converted appropriately to urea and removed from the body. The result of a build up in ammonia levels lead to an increase in cerebral edema, or hepatic encephalopathy. What nursing priority will guide your plan of care? Provide rationale. 1 Point The major priority currently for this patient will be decreasing intracranial pressure. Decreasing the level of ammonia in the body will undo the cerebral edema he is developing the rationale behind this is that increases in ICP will ultimately lead to coma and death for the patient and without treatment that is the trajectory his disease will take. What THREE interventions will you initiate based on this priority? 3 Points Nursing Interventions: © 2014 Keith Rischer/www.KeithRN.com Rationale: Metabolism Rapid Reasoning NURS 2900 10 Points Evaluate serum ammonia levels daily and administer lactulose as Administer lactulose and monitor prescribed. Lactulose converts ammonia to ammonium which inhibits it from crossing the blood brain barrier thereby decreasing the patient’s ammonia levels via labs hepatic encephalopathy it also decreases the overall production of ammonia by the gut. Monitor neurologic status for Monitoring for neurologic status changes is necessary because as changes ammonia levels improve or worse so will the patients neurological functioning. The patient currently has decreased level of consciousness and asterixis which are associated with stage two hepatic encephalopathy. Monitor protein levels in hepatic encephalopathy patients Patients with hepatic encephalopathy should have low to moderate amounts of protein especially if they are headed towards coma due to the production of ammonia as a byproduct in cellular respiration. Lowered levels of protein lead to lowered amounts of ammonia production but this is a catch 22 in patients because cellular processes require added amounts of protein to heal in the presence of injury. Maintain bedrest Reduce metabolic and hepatic demands on the body which decreases the risk of increased ammonia build up. Have the patient write there name each day Monitor fluid and electrolyte balance. © 2014 Keith Rischer/www.KeithRN.com Decreases in ability to write ones name or increases in the ability of patient to write clearly can be an indicator of neurological function Monitoring fluid and electrolyte balance will decrease excess energy expenditure which will result in worsened ammonia levels.
