The nurse determines that a client's intracranial pressure waveform is normal. What did the nurse observe to make this clinical determination?
1. Three pressure peaks
4. Absence of pressure peaks
3. Synchronization with heart rate
2. Synchronization with respiratory rate
Rationale 1: A normal ICP waveform has three pressure peaks.
Rationale 2: An abnormal waveform would have absent pressure peaks.
Rationale 3: The intracranial pressure waveform is not synchronized with heart rate.
Rationale 4: The intracranial pressure waveform is not synchronized with respiratory rate.
Global Rationale: A normal ICP waveform has three pressure peaks. An abnormal waveform would have absent pressure peaks. The intracranial pressure waveform is not synchronized with heart or respiratory rate.

Which statements would the nurse supervisor evaluate as indicating that the nurse needs more information? Note: Credit will be given only if all correct choices and no incorrect choices are selected. Select all that apply. 1. "When water combines with carbon dioxide, carbonic acid is produced." 2. "Carbon dioxide is a potential acid that is excreted through the lungs." 3. "Body metabolism produces lactic acids, which are constantly eliminated in the lungs." 4. "Sodium bicarbonate buffers the blood by removing hydrogen ions from the blood." 5. "Carbonic acid dissociates into sodium and bicarbonate.".
