A nurse is caring for a client who experienced severe head trauma. The client's partner asks the nurse why they are concerned about the mean arterial pressure (MAP). The nurse should explain that MAP determines which of the following?
Cerebral blood flow
The client's intake and output needs
Regulation of blood pressure
Resorption of cerebrospinal fluid
The Correct Answer is A
A. Cerebral blood flow. MAP is crucial for maintaining adequate cerebral perfusion pressure, ensuring enough blood flow to the brain.
B. The client's intake and output needs. MAP does not directly influence intake and output needs; it is more directly related to blood flow and tissue perfusion.
C. Regulation of blood pressure. MAP is a measure of average blood pressure but not a regulator of it.
D. Resorption of cerebrospinal fluid. CSF resorption is not directly influenced by MAP; it’s regulated by intracranial pressure and other factors.
