A client has been diagnosed with myxedema from long-standing hypothyroidism. What clinical manifestations of this disorder does the nurse recognize as progressing to myxedema coma? Select all that apply.
Hypertension
Restlessness
Increased level of alertness
Tachycardia
Hypotension
Bradycardia
Hypoventilation
Hyperventilation
Correct Answer : E,F,G
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.

Correct Answer is B
Explanation
Choice A Reason:
A 42-year-old man with gastroesophageal reflux disease (GERD) is not at the highest risk for obstructive sleep apnea (OSA). While GERD can be associated with OSA, it is not a primary risk factor. The main risk factors for OSA include obesity, age, and anatomical features that can obstruct the airway. Therefore, this individual is not at the greatest risk compared to others.
Choice B Reason:
A 55-year-old woman who is 50 lb (23 kg) overweight is at significant risk for developing OSA. Obesity is one of the most critical risk factors for OSA because excess weight can lead to fat deposits around the upper airway, which can obstruct breathing during sleep. Additionally, being overweight increases the likelihood of other conditions that can exacerbate OSA, such as hypertension and metabolic syndrome.
Choice C Reason:
A 20-year-old woman who is 8 months pregnant may experience temporary sleep disturbances, including snoring and mild sleep apnea, due to hormonal changes and increased abdominal pressure. However, pregnancy-related sleep apnea is usually transient and resolves after childbirth. Therefore, while she may have an increased risk during pregnancy, it is not as significant as the risk posed by obesity.
Choice D Reason:
A 73-year-old man with type 2 diabetes mellitus has an increased risk of OSA, as diabetes is associated with obesity and metabolic syndrome, which are risk factors for OSA. However, the presence of diabetes alone does not pose as high a risk as obesity. Therefore, while this individual is at risk, it is not as high as the risk associated with being significantly overweight.
Correct Answer is A
Explanation
Choice A Reason:
Constant bubbling in the water seal chamber of a chest drainage system typically indicates an air leak. This can occur if there is a break in the system, allowing air to enter. The air leak could be from the chest tube insertion site, the tubing, or the drainage system itself. Identifying and correcting the source of the air leak is crucial to ensure the system functions properly and the patient’s condition does not worsen.
Choice B Reason:
A tension pneumothorax is a life-threatening condition where air accumulates in the pleural space and cannot escape, leading to increased pressure on the lungs and other thoracic structures. While a tension pneumothorax can cause significant respiratory distress, it is not typically indicated by constant bubbling in the water seal chamber. Instead, signs of tension pneumothorax include tracheal deviation, hypotension, and severe respiratory distress.
Choice C Reason:
A kink in the tubing of a chest drainage system can obstruct the flow of air and fluid, but it does not cause constant bubbling in the water seal chamber. Instead, a kink would likely result in a lack of drainage or intermittent bubbling as the obstruction temporarily blocks and then allows passage of air or fluid.
Choice D Reason:
Increased drainage in a chest tube system indicates that more fluid or air is being removed from the pleural space, but it does not cause constant bubbling in the water seal chamber. Increased drainage might be seen in cases of hemothorax or pleural effusion, where large amounts of fluid are present.
Choice E Reason:
Tidaling refers to the normal rise and fall of water in the water seal chamber with the patient’s respiratory cycle. It indicates that the chest tube is patent and functioning correctly. Absence of tidaling could suggest that the lung has fully re-expanded or that there is an obstruction in the system. However, tidaling itself does not cause constant bubbling.
