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 D
Explanation
Choice A: Periodic Nystagmus
Nystagmus, which is characterized by involuntary eye movements, can be a symptom of various neurological conditions, including bacterial meningitis. However, it is not typically an immediate concern compared to other symptoms. Nystagmus indicates potential issues with the brainstem or cerebellum, but it does not directly threaten the patient’s life or indicate a rapid deterioration in condition. Therefore, while it is important to monitor, it is not the most urgent finding.
Choice B: Severe Unrelenting Headaches
Severe headaches are a common symptom of bacterial meningitis due to the inflammation of the meninges. While they are extremely painful and distressing for the patient, they are not as immediately life-threatening as a decreased level of consciousness. Headaches indicate increased intracranial pressure, which is serious, but the priority is to address symptoms that indicate a more rapid decline in neurological function.
Choice C: Photophobia During the Day
Photophobia, or sensitivity to light, is another common symptom of meningitis. It results from the irritation of the meninges and is often accompanied by headaches. While photophobia can be very uncomfortable and indicative of meningitis, it is not an immediate concern compared to a decreased level of consciousness. Photophobia does not directly indicate a life-threatening situation.
Choice D: Decreased Level of Consciousness
A decreased level of consciousness is the most immediate concern for a nurse caring for a patient with bacterial meningitis. This symptom indicates a significant and potentially rapid decline in the patient’s neurological status. It can be a sign of increased intracranial pressure, brain swelling, or other severe complications. Immediate medical intervention is required to prevent further deterioration and potential fatality. Monitoring and addressing changes in consciousness are critical in managing bacterial meningitis effectively.
Correct Answer is ["A"]
Explanation
Choice A: Monitor for hypernatremia.
Hypernatremia, or high sodium levels in the blood, is a common complication of diabetes insipidus due to excessive water loss and insufficient water intake. Monitoring for hypernatremia involves regular blood tests to check sodium levels. Symptoms of hypernatremia include extreme thirst, confusion, muscle twitching, and seizures. Early detection and management are crucial to prevent severe complications.
Choice B: Monitor neuro status.
Monitoring neurological status is essential in patients with diabetes insipidus because severe hypernatremia can lead to neurological symptoms such as confusion, irritability, seizures, and even coma. Regular assessments of mental status, level of consciousness, and neurological function help in early detection of complications and timely intervention.
Choice C: Monitor for hyponatremia.
While hyponatremia (low sodium levels) is less common in diabetes insipidus, it can occur if there is excessive water intake without adequate sodium replacement. Symptoms include headache, nausea, vomiting, confusion, and seizures. Monitoring sodium levels helps in maintaining a balance and preventing complications.
Choice D: Monitor urine specific gravity.
Urine specific gravity measures the concentration of solutes in the urine. In diabetes insipidus, urine is typically very dilute, with a specific gravity of less than 1.005. Regular monitoring helps in assessing the effectiveness of treatment and the patient’s hydration status. It also aids in differentiating diabetes insipidus from other conditions with similar symptoms.
Choice E: Monitor strict I&O.
Strict monitoring of intake and output (I&O) is crucial in managing diabetes insipidus. This involves accurately measuring all fluids consumed and excreted to ensure proper hydration and electrolyte balance. It helps in identifying trends in fluid loss and guiding appropriate fluid replacement therapy.
