Final answer:
The nurse will point to the upper left quadrant of the abdomen to show where the spleen is located. The spleen is involved in filtering blood and responding to blood-borne pathogens and is situated near the stomach and left kidney.
Step-by-step explanation:
The nurse will point to the upper left quadrant of the abdomen to indicate the location of the spleen when answering the client's question. The spleen is a lymphatic organ located near the stomach and left kidney, and it plays a critical role in filtering pathogens and worn-out red blood cells from the blood. Additionally, it harbors numerous phagocytes and lymphocytes that combat and prevent circulatory infections by killing and removing pathogens from the blood. The spleen is attached to the lateral border of the stomach via the gastrosplenic ligament and is situated just inferior to the diaphragm in the upper-left quadrant of the abdominopelvic cavity.
