Question 1 of 5
Which laboratory finding indicates the resolution of a patient's acute pancreatitis?
Correct Answer: B
Rationale: A decreasing serum amylase level is indicative of the resolution of acute pancreatitis. Amylase is an enzyme that helps digest carbohydrates and is released in large amounts when the pancreas is inflamed. As the inflammation resolves, amylase levels decrease.
Question 2 of 5
Which laboratory finding indicates the resolution of a patient's acute pancreatitis?
Correct Answer: B
Rationale: During an episode of acute pancreatitis, serum concentrations of amylase and lipase rise significantly, often within hours of pancreatic injury. These elevated enzyme levels are key components in diagnosing the condition. As the inflammation subsides and the pancreas begins to heal, the levels of these enzymes typically decrease, returning to normal ranges.
Question 3 of 5
A nurse is caring for a patient diagnosed with peptic ulcer disease. Which complication would result in gastric contents spilling into the patient's peritoneal cavity?
Correct Answer: C
Rationale: Perforation is the correct answer because it describes a hole forming in the wall of the stomach or duodenum, allowing gastric contents to spill into the peritoneal cavity, leading to peritonitis, which is a severe and life-threatening condition.
Question 4 of 5
A nurse is preparing to administer a dose of lactulose to a client who has cirrhosis. The client states, 'I don't need this medication. I am not constipated.' The nurse should explain that in clients who have cirrhosis, lactulose is used to decrease levels of which of the following components in the bloodstream?
Correct Answer: B
Rationale: Ammonia is produced by the breakdown of proteins in the intestines and is normally processed by the liver. In cirrhosis, the liver's ability to convert ammonia to urea is impaired, leading to increased levels in the blood. Lactulose helps reduce blood ammonia levels by converting it into ammonium, which is then excreted.
Question 5 of 5
A nurse is reviewing the laboratory data of a client following a hemodialysis treatment. The nurse should expect to find a decrease in which of the following laboratory values?
Correct Answer: B
Rationale: Potassium levels are often elevated in clients with renal failure due to the kidneys' inability to excrete potassium. Hemodialysis helps to remove excess potassium from the bloodstream, thereby decreasing its levels.
