Answer to Question 1

B
Herniation of intracerebral contents results in the shifting of tissue from one compartment of the brain to another and places pressure on cerebral vessels and vital function centers of the brain. If unchecked, herniation rapidly causes death as a result of the cessation of cerebral blood flow and respirations. Signs and symptoms of brain herniation include fixed and dilated pupils, flaccidity, and respiratory arrest. The intracranial pressure drops as the pressure is relieved by shifting the intracranial components downward.

Answer to Question 2

A
A damped waveform occurs when communication from the artery to the transducer is interrupted and produces false values on the monitor and oscilloscope. Damping is caused by a fibrin sleeve that partially occludes the tip of the catheter, by kinks in the catheter or tubing, or by air bubbles in the system.
