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 ["B","C","E","F"]
Explanation
Choice A Reason:
Weight gain is not typically associated with tuberculosis (TB). In fact, weight loss is a common symptom of TB due to the chronic nature of the infection and the body’s increased metabolic demands to fight the disease. Patients with TB often experience a loss of appetite and significant weight loss as the disease progresses.
Choice B Reason:
Low-grade fever is a common symptom of TB. The body’s immune response to the infection often results in a persistent low-grade fever, which can be one of the early signs of the disease. This fever is usually accompanied by other systemic symptoms such as night sweats and fatigue.
Choice C Reason:
Dyspnea, or difficulty breathing, can occur in patients with TB, especially if the infection has caused significant lung damage or if there is a large amount of fluid in the pleural space (pleural effusion). Dyspnea is a concerning symptom that indicates the need for further evaluation and treatment.
Choice D Reason:
Contusion, or bruising, is not a symptom associated with TB. TB primarily affects the lungs and can cause systemic symptoms, but it does not typically cause bruising. Contusions are more commonly associated with trauma or conditions that affect blood clotting.
Choice E Reason:
Lethargy, or a general sense of fatigue and weakness, is a common symptom of TB. The chronic nature of the infection and the body’s ongoing immune response can lead to significant fatigue. Patients with TB often feel tired and may have difficulty performing daily activities.
Choice F Reason:
Night sweats are a hallmark symptom of TB. Patients often experience drenching night sweats that can be quite severe. This symptom, along with fever and weight loss, is part of the classic triad of TB symptoms and is an important indicator for healthcare providers to consider TB in the differential diagnosis.
Correct Answer is ["A","C","E"]
Explanation
Choice A Reason:
Weight loss.
Weight loss is a common symptom of hyperthyroidism. This condition speeds up the body’s metabolism, causing the body to burn calories more quickly than usual. Despite an increased appetite, individuals with hyperthyroidism often experience significant weight loss. This symptom is a direct result of the overproduction of thyroid hormones, which increases the metabolic rate.
Choice B Reason:
Intolerance to cold.
Intolerance to cold is not typically associated with hyperthyroidism; it is more commonly a symptom of hypothyroidism. Hyperthyroidism usually causes heat intolerance due to the increased metabolic rate, which raises the body’s temperature. Therefore, this choice is not relevant to hyperthyroidism.
Choice C Reason:
An elevated systolic blood pressure.
An elevated systolic blood pressure can be a symptom of hyperthyroidism. The increased levels of thyroid hormones can cause the heart to work harder, leading to higher blood pressure. This symptom is important to monitor as it can lead to further cardiovascular complications if left untreated.
Choice D Reason:
A heart rate of 90 bpm.
A heart rate of 90 bpm is within the normal range for adults and is not specifically indicative of hyperthyroidism. Hyperthyroidism typically causes a rapid or irregular heartbeat, often exceeding 100 bpm. Therefore, this choice does not accurately reflect a clinical manifestation of hyperthyroidism.
Choice E Reason:
Increased fatigability.
Increased fatigability is a common symptom of hyperthyroidism. Despite the increased metabolic rate, individuals with hyperthyroidism often feel tired and weak. This paradoxical symptom occurs because the body’s systems are overworked and cannot sustain the heightened activity levels, leading to fatigue.
