A nurse admits a client to the emergency department who reports nausea and vomiting that worsens when he lies down. Antacids do not help. The provider suspects acute pancreatitis. Which of the following laboratory test results should the nurse expect to see?
Increased serum amylase
Increased serum calcium
Decreased WBC
Decreased serum lipase
The Correct Answer is A
Choice A Reason:
Increased serum amylase is a key indicator of acute pancreatitis. Amylase is an enzyme produced by the pancreas to help digest carbohydrates. In cases of acute pancreatitis, the pancreas becomes inflamed, leading to the release of amylase into the bloodstream. Elevated levels of serum amylase, typically more than three times the upper limit of normal, are a strong indication of acute pancreatitis. This enzyme level usually rises within a few hours of the onset of pancreatitis and can remain elevated for several days.

Choice B Reason:
Increased serum calcium is not typically associated with acute pancreatitis. In fact, acute pancreatitis can often lead to hypocalcemia (low calcium levels) due to fat saponification in the pancreas, where calcium binds with fatty acids. Therefore, an increase in serum calcium would not be expected in a patient with acute pancreatitis. Monitoring calcium levels is important, but an increase is not a diagnostic marker for this condition.
Choice C Reason:
Decreased WBC (white blood cell count) is not a characteristic finding in acute pancreatitis. On the contrary, acute pancreatitis often leads to an elevated WBC count due to the inflammatory response in the body. Leukocytosis (increased WBC) is a common finding in many inflammatory and infectious conditions, including acute pancreatitis. Therefore, a decreased WBC count would not be expected and does not support the diagnosis of acute pancreatitis.
Choice D Reason:
Decreased serum lipase is incorrect. Similar to amylase, lipase is another enzyme produced by the pancreas, which helps in the digestion of fats. In acute pancreatitis, serum lipase levels also increase significantly, often more than three times the upper limit of normal. Lipase levels tend to rise slightly later than amylase but remain elevated for a longer period, making it a useful marker for diagnosing acute pancreatitis. Therefore, decreased serum lipase would not be expected in this condition.

Correct Answer is A
Explanation
Choice A: Ammonia
Lactulose is administered to patients with hepatic encephalopathy to reduce the levels of ammonia in the blood. Hepatic encephalopathy occurs due to the liver’s inability to detoxify ammonia, a byproduct of protein metabolism. Lactulose works by converting ammonia into ammonium, which is then excreted in the stool. This helps to lower blood ammonia levels and alleviate the symptoms of hepatic encephalopathy.
Choice B: Dysarthria
Dysarthria, or difficulty in articulating words, is a common symptom of Parkinson’s disease. It results from the muscle rigidity and bradykinesia (slowness of movement) that affect the muscles involved in speech. Patients with Parkinson’s often have a soft, monotone voice and may struggle with the clarity of their speech.
Choice C: Muscle Rigidity
Muscle rigidity is one of the hallmark symptoms of Parkinson’s disease. It refers to the stiffness and inflexibility of the muscles, which can affect any part of the body. This rigidity can lead to discomfort and pain, and it contributes to the characteristic stooped posture and shuffling gait seen in Parkinson’s patients.
Choice D: Seizures
Seizures are not typically associated with Parkinson’s disease. While Parkinson’s affects the central nervous system, it primarily impacts motor function rather than causing seizure activity. Therefore, this is not a common finding in Parkinson’s patients.
Choice E: Drooling at Times
Drooling, or sialorrhea, is a common symptom in Parkinson’s disease. It occurs due to the decreased ability to swallow saliva, which can result from muscle rigidity and bradykinesia affecting the muscles involved in swallowing. This can be particularly bothersome for patients and may require management strategies.
Choice F: Mask-like Facial Expression
A mask-like facial expression, also known as hypomimia, is a common feature of Parkinson’s disease. It results from the rigidity and bradykinesia affecting the facial muscles, leading to reduced facial expressions and a fixed, staring appearance.
Choice G: Shuffled Gait
A shuffled gait is a characteristic feature of Parkinson’s disease. Patients often take small, shuffling steps and may have difficulty initiating movement. This gait pattern is due to the combination of muscle rigidity, bradykinesia, and postural instability.
Choice H: Stooped Posture
Stooped posture is another common symptom of Parkinson’s disease. It results from the muscle rigidity and postural instability that affect the patient’s ability to maintain an upright position. This can lead to a forward-leaning posture and balance issues.
Correct Answer is D
Explanation
Order a high-fiber diet
Choice A Reason:
Encourage dietary intake
Encouraging dietary intake is generally important for maintaining nutritional status, but it is not specific to the preparation for a barium enema. The preparation for a barium enema typically involves dietary restrictions to ensure the colon is clear for the procedure. Therefore, this choice is not correct.
Choice B Reason:
Encourage plenty of fat
Encouraging plenty of fat is not appropriate for the preparation of a barium enema. High-fat foods can slow down the digestive process and may interfere with the clarity of the images obtained during the procedure. Therefore, this choice is not correct.
Choice C Reason:
Serve dairy products
Serving dairy products is not recommended before a barium enema. Dairy products can cause gas and bloating, which can interfere with the procedure. Additionally, some patients may be lactose intolerant, which can further complicate the preparation. Therefore, this choice is not correct.
Choice D Reason:
Order a high-fiber diet
Ordering a high-fiber diet is the correct choice. A high-fiber diet helps to clear the intestines by promoting bowel movements. This is important for ensuring that the colon is empty and clear for the barium enema, which allows for better imaging and more accurate results.
