Which of the following symptoms might indicate that the patient is now experiencing a thyrotoxic crisis following the diagnosis of Graves' disease?
Decreased respirations and CO2 retention
Seizures and extreme tachycardia
Constipation and a swollen abdomen
Hypotension and bradycardia
The Correct Answer is B
A. Decreased respirations and CO2 retention: A thyrotoxic crisis (thyroid storm) typically involves increased, not decreased, respiratory rates and CO2 retention due to increased metabolic activity.
B. Seizures and extreme tachycardia: Thyrotoxic crisis is characterized by severe symptoms including extreme tachycardia, fever, and potentially seizures due to excessive thyroid hormone levels.
C. Constipation and a swollen abdomen: Constipation and abdominal swelling are more typical of hypothyroidism rather than a thyrotoxic crisis.
D. Hypotension and bradycardia: Thyrotoxic crisis usually causes tachycardia and hypertension rather than bradycardia and hypotension.

Correct Answer is D
Explanation
A. Obesity, age over 40, and female gender: While obesity and age can be risk factors for GERD, gender alone is not a significant factor. Excessive alcohol consumption, as indicated in option D, is a stronger link to GERD.
B. Accelerated gastric emptying: This is incorrect. GERD is more commonly associated with delayed gastric emptying or increased acid production rather than accelerated gastric emptying.
C. Incompetent rectal sphincter: This is incorrect. GERD is associated with an incompetent lower esophageal sphincter, not the rectal sphincter.
D. Drinking 12 cans of beer per day: Excessive alcohol consumption can relax the lower esophageal sphincter and increase the risk of GERD by allowing stomach acid to flow back into the esophagus.
