A 75-year-old patient presents with dyspnea and coughing for the past two days. The patient's physical exam shows jugular venous distention and pitting edema. The patient is admitted, and the physician orders an echocardiogram, diuretics, and a cardiac diet.

A. The general pathogen fighting system people are born with that does not change over time:

Innate immunity is nonspecific, present at birth, and provides immediate defense without adapting to specific pathogens.

B. The process in which endothelial cells are separated away from each other, making the capillaries larger:

This describes vascular permeability, a component of inflammation, not a definition of innate immunity.

C. The process by which the body automatically reacts to tissue injured by trauma or bacteria:

This describes the inflammatory response, which is a mechanism of innate immunity, but not the full definition of innate immunity itself.

D. The set of proteins that enhance the ability of the body to initiate the inflammatory response, attack a pathogen, and remove damaged cell material:

This describes the complement system, which is part of innate immunity, but again, it is not the complete definition of innate immunity.

A. The kidney and a portion of the bladder:

This removal describes procedures like radical cystectomy, not simple nephrectomy.

B. The kidney in its entirety:

A simple nephrectomy involves removing only the kidney (not adrenal gland, bladder, or lymph nodes).

C. Cancer within the kidney and some tissue around the cancer:

This describes a partial nephrectomy.

D. The kidney, the adrenal gland, and some surrounding tissue:

This describes a radical nephrectomy, not a simple nephrectomy.
