The nurse is caring for a client immediately following a cardioversion. What nursing actions are appropriate? (Select all that apply.)

Choice A reason:

Hypertension is not typically associated with myxedema coma. Myxedema coma is characterized by severe hypothyroidism, which usually leads to low blood pressure (hypotension) rather than high blood pressure (hypertension). Therefore, hypertension is not a clinical manifestation that indicates progression to myxedema coma.

Choice B reason:

Restlessness is not a common symptom of myxedema coma. Patients with myxedema coma often present with lethargy, confusion, or even coma due to the severe slowing of metabolic processes. Restlessness is more commonly associated with hyperthyroidism or other conditions that increase metabolic activity.

Choice C reason:

An increased level of alertness is contrary to the symptoms of myxedema coma. Myxedema coma typically presents with decreased mental status, including confusion, stupor, or coma. Therefore, an increased level of alertness would not be indicative of progression to myxedema coma.

Choice D reason:

Tachycardia (rapid heart rate) is not a typical symptom of myxedema coma. Instead, myxedema coma is associated with bradycardia (slow heart rate) due to the severe hypothyroid state. Tachycardia is more commonly seen in hyperthyroid conditions.

Choice E reason:

Hypotension (low blood pressure) is a key clinical manifestation of myxedema coma. The severe hypothyroid state leads to decreased cardiac output and vascular resistance, resulting in hypotension. This is a critical sign that the nurse should recognize as indicative of progression to myxedema coma.

Choice F reason:

Bradycardia (slow heart rate) is another hallmark of myxedema coma. The decreased metabolic rate in severe hypothyroidism leads to a reduced heart rate. Recognizing bradycardia is essential in identifying the progression to myxedema coma.

Choice G reason:

Hypoventilation (reduced breathing rate) is a significant symptom of myxedema coma. The severe hypothyroid state can lead to respiratory depression, resulting in hypoventilation. This can further exacerbate the patient’s condition and requires immediate medical attention.

Choice H reason:

Hyperventilation (increased breathing rate) is not associated with myxedema coma. Patients with myxedema coma typically experience hypoventilation due to the severe slowing of metabolic processes. Hyperventilation would be more indicative of conditions that increase metabolic activity or respiratory drive.

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.
