Questions

1. A nurse is preparing to obtain intracranial pressure readings from a patient with an external ventricular drain. What action will the nurse perform first?

Zero the transducer.

Assess the patient's neurologic status.

Verify that the transducer is at the level of the patient's tragus.

Ensure the patient is properly positioned for the procedure and the patient's condition.

2. The nurse has just zeroed the transducer when the patient turns his head toward the nurse to ask a question about the procedure. After answering the patient's question, which action does the nurse take next?

Ensure the transducer is at the level of the patient's tragus using the patient's new position.

Notify the healthcare practitioner.

Zero the transducer again using the patient's new position.

Reposition the patient and ask him to remain still during the procedure.

3. The nurse looks at the monitor and sees that the patient's ICP waveform is in the descending step pattern and matches the patient's previous reading. What does this pattern indicate?

There is no significance to the descending step pattern.

The patient's ICP waveform indicates an impending rise in ICP.

The patient's ICP waveform is normal.

The patient's waveform indicates decreased brain compliance.

4. The nurse is obtaining ICP readings from a patient with an open EVD drainage system. What action does the nurse take in order to obtain an accurate ICP reading?

The nurse tilts the patient's head to the side facing the transducer.

The nurse closes the stopcock to the drain.

The nurse closes the stopcock to the drain.

The nurse levels the transducer to the drain's exit site.

5. The nurse is preparing to obtain ICP readings from a patient with an EVD and a cervical spine injury. Into which position does the nurse anticipate placing the patient?

Reverse Trendelenburg.

Trendelenburg.

Supine with the patient's head positioned midline and the head of the bed elevated 30 degrees.

Supine with the patient's head positioned midline and the head of the bed elevated 45 degrees.
