Which of the following describes a congenital defect resulting in an incomplete formation of the esophagus?

Choice A rationale

The urethra is a tube that carries urine from the bladder out of the body. It is not typically the location of a pyelonephritis infection.

Choice B rationale

The bladder is part of the lower urinary tract and is typically not the location of a pyelonephritis infection.

Choice C rationale

The ureters are tubes that carry urine from the kidneys to the bladder. While they can be affected by urinary tract infections, they are not typically the primary location of a pyelonephritis infection.

Choice D rationale

Pyelonephritis is an infection that occurs in the kidneys. It typically starts in the lower urinary tract, such as the bladder, and then spreads to one or both kidneys.

Choice A rationale

While facial puffiness, bradycardia, and lethargy can be symptoms of many conditions, they are not typically signs of Graves’ disease.

Choice B rationale

Exophthalmos (bulging eyes) and tachycardia (rapid heart rate) are typical signs of Graves’ disease.

Choice C rationale

Delayed physical and intellectual development is not typically a sign of Graves’ disease.

Choice D rationale

While a goiter (enlarged thyroid gland) is a common sign of Graves’ disease, a decreased basal metabolic rate (MBR) is not typically associated with this condition.
