When explaining normal intracranial pressure (ICP) balance to the patient's family, which three components would the nurse include?
Glucose level, BP, and brain tissue
BP, brain tissue, and cerebrospinal fluid
BP, brain tissue, body mass index
BP, brain tissue, and ventricles of the brain
The Correct Answer is B
A. Glucose level, BP, and brain tissue: Glucose level is not a key component of ICP balance.
B. BP, brain tissue, and cerebrospinal fluid: These are the primary components that contribute to ICP balance. Changes in any of these can affect pressure inside the skull.
C. BP, brain tissue, body mass index: BMI is not directly related to ICP balance.
D. BP, brain tissue, and ventricles of the brain: The ventricles are involved in cerebrospinal fluid production but are not one of the primary components of ICP balance as a whole.
