What is the pathophysiology of type 1 diabetes mellitus (DM)?
Loss of insulin receptors on the target cell, resulting in insulin resistance
Overproduction of insulin from the beta cells of the pancreas
A pituitary tumor in the brain, resulting in increased antidiuretic hormone production
Destruction of the beta cells within the pancreas, resulting in an inability to produce insulin
The Correct Answer is D
Choice A rationale
Loss of insulin receptors on the target cell, resulting in insulin resistance, is a characteristic of type 2 diabetes mellitus, not type 15.
Choice B rationale
Overproduction of insulin from the beta cells of the pancreas is not a characteristic of type 1 diabetes mellitus. In fact, type 1 diabetes involves a lack of insulin due to the destruction of beta cells.
Choice C rationale
A pituitary tumor in the brain, resulting in increased antidiuretic hormone production, is not related to the pathophysiology of type 1 diabetes mellitus.
Choice D rationale
Type 1 diabetes mellitus is indeed caused by the destruction of the beta cells within the pancreas, which results in an inability to produce insulin.

Correct Answer is D
Explanation
Choice D rationale
Fluid retention is a factor that leads to electrolyte imbalance in a client with Syndrome of Inappropriate Antidiuretic Hormone (SIADH). SIADH is a condition where the body makes too much antidiuretic hormone (ADH), leading to water retention. This retention dilutes the blood, leading to low levels of sodium, a condition known as hyponatremia.
Correct Answer is D
Explanation
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.
