Extract:
Question 1 of 5
The nurse is caring for a client with a head injury who has increased ICP. The physician plans to reduce the cerebral edema by reversing dilation of cerebral blood vessels. Which physician prescription would the nurse expect to accomplish this?
Correct Answer: A
Rationale: Hyperventilation is utilized to decrease the PCO2 to 27-30, producing cerebral blood vessel constriction. Answers B, C, and D can decrease cerebral edema, but not by constriction of cerebral blood vessels; therefore, they are wrong.
Question 2 of 5
The nurse is reinforcing teaching with a client who has a prescription for sertraline for the treatment of depression. Which of the following statements by the client would indicate a correct understanding of the teaching?
