Final answer:
The laser commonly used to coagulate bleeders during laparoscopic procedures is the D. Argon laser.
Step-by-step explanation:
The Argon laser is a gas laser that produces a blue-green light with a wavelength of 488-514 nm. It is well-suited for coagulating blood vessels because its wavelength is selectively absorbed by hemoglobin in red blood cells, causing the vessels to coagulate and stop bleeding.
In a laparoscopic procedure, the Argon laser can be delivered through a thin fiber optic cable, allowing the surgeon to precisely target and coagulate bleeders without the need for open surgery. This minimally invasive approach helps reduce patient discomfort, shorten recovery time, and minimize scarring.
In conclusion, the correct answer is D. Argon laser, the laser commonly used to coagulate bleeders during laparoscopic procedures. Its blue-green light is selectively absorbed by hemoglobin, allowing the laser to effectively coagulate blood vessels and stop bleeding.
