A client with a history of seizures is scheduled for an electroencephalogram (EEG). Which instruction does the nurse give the client before the test?

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:

Thirst is a common and expected symptom after an EGD, especially if the client has been fasting before the procedure. It does not typically indicate a complication and can be managed by gradually reintroducing fluids as tolerated. Therefore, thirst does not require further nursing assessment beyond routine post-procedure care.

Choice B Reason:

A sore throat is also a common symptom following an EGD. The procedure involves passing an endoscope through the throat, which can cause temporary irritation and discomfort. This symptom usually resolves on its own within a few days and does not indicate a serious complication. Therefore, a sore throat does not require further nursing assessment beyond providing comfort measures such as lozenges or warm saltwater gargles.

Choice C Reason:

Abdominal distention is a concerning symptom that requires further nursing assessment. It can indicate complications such as perforation, bleeding, or infection following the EGD. Perforation of the gastrointestinal tract is a rare but serious complication that can lead to peritonitis and sepsis if not promptly addressed. Therefore, any signs of abdominal distention should be reported to the provider immediately for further evaluation and intervention.

Choice D Reason:

Drowsiness is a common side effect of the sedatives used during the EGD procedure. It is expected that the client may feel drowsy or sleepy for a few hours after the procedure as the sedative wears off. This symptom does not typically require further nursing assessment unless it persists for an unusually long time or is accompanied by other concerning symptoms such as difficulty breathing or altered mental status.
