Which statement describes a rare, potentially life-threatening complication of myxedema?
The pituitary hormones release antidiuretic hormone in response to hypothyroid signaling, resulting in extensive diuresis.
A trigger such as illness or trauma results in an exaggeration of hypothyroidism that may include severe hypotension, seizures, and/or coma.
Over secretion of thyroid-stimulating hormones (TSH) leads to increased excretion of T3 and T4 with dangerous cardiac symptoms.
The heart does not allow proper flow of fluid throughout the body due to the elevated levels of circulating thyroid hormone.
The Correct Answer is B
Choice A rationale
The pituitary hormones releasing antidiuretic hormone in response to hypothyroid signaling, resulting in extensive diuresis, is not a known complication of myxedema. Myxedema is a severe form of hypothyroidism characterized by an underactive thyroid, not an overactive pituitary gland.
Choice B rationale
Myxedema coma, a rare but life-threatening complication of myxedema, can indeed be triggered by illness or trauma, leading to an exaggeration of hypothyroid symptoms. This can include severe hypotension, seizures, and/or coma. This condition is considered a medical emergency and requires immediate treatment.
Choice C rationale
Over secretion of thyroid-stimulating hormones (TSH) leading to increased excretion of T3 and T4 with dangerous cardiac symptoms is not associated with myxedema. Instead, this scenario is more likely to occur in hyperthyroidism, a condition characterized by an overactive thyroid, not an underactive one.
Choice D rationale
The heart not allowing proper flow of fluid throughout the body due to elevated levels of circulating thyroid hormone is not a characteristic of myxedema. In myxedema, the levels of thyroid hormones are low, not high.

Correct Answer is D
Explanation
Choice A rationale
Urethrocele refers to the prolapse of the urethra, which is the tube that carries urine from the bladder out of the body. It does not refer to the prolapse of the bladder.
Choice B rationale
Rectocele refers to the prolapse of the rectum into the vagina. It does not refer to the prolapse of the bladder.
Choice C rationale
Uterine prolapse refers to the descent of the uterus into the vagina. It does not refer to the prolapse of the bladder.
Choice D rationale
Cystocele, also known as a prolapsed bladder, is the term for when the bladder drops from its usual position in the pelvis and pushes on the wall of the vagina.
