The nurse administers mannitol (Osmitrol) to the client with increased intracranial pressure. Which parameter requires close monitoring?
- A. Muscle relaxation.
- B. Intake and output.
- C. Widening of the pulse pressure.
- D. Pupil dilation.
Correct Answer: B
Rationale: Mannitol is an osmotic diuretic used to reduce ICP by drawing fluid from brain tissue. Monitoring intake and output is critical to assess its effectiveness and prevent dehydration or electrolyte imbalances. Muscle relaxation, pulse pressure, and pupil dilation are not directly related to mannitol's primary effects.

If a client displays risk factors for coronary artery disease, such as smoking cigarettes, eating a diet high in saturated fat, or leading a sedentary lifestyle, techniques of behavior modification may be used to help the client change the behavior.

- B. Withholding praise until the new behavior is well established.
- C. Rewarding the client whenever the acceptable behavior is performed.
