CNRN Neurological Assessment and Monitoring 2

Question 1

The nurse is monitoring a patient's cerebral perfusion pressure (CPP). Which formula is used to calculate CPP?

Accepted Answer

CPP = MAP − ICP

Answer

Cerebral perfusion pressure is calculated as mean arterial pressure minus intracranial pressure (CPP = MAP − ICP).

Question 2

Which reflex, when absent, suggests dysfunction at the level of the medulla?

Accepted Answer

Gag reflex

Answer

The gag reflex (CN IX and X) is mediated at the medulla; its absence indicates medullary dysfunction.

Question 3

A positive Romberg test (patient sways when eyes are closed) indicates impairment in which system?

Accepted Answer

Proprioceptive or vestibular function

Answer

A positive Romberg test indicates impaired proprioception or vestibular function, as the patient cannot maintain balance without visual input.

Question 4

When assessing for meningeal irritation, the nurse flexes the patient's hip and knee, then extends the knee. The patient reports pain and resists extension. This describes:

Accepted Answer

Kernig's sign

Answer

Kernig's sign is positive when the patient resists or experiences pain with knee extension after hip flexion, indicating meningeal irritation.

Question 5

In continuous EEG monitoring, which finding requires the nurse to immediately notify the neurologist?

Accepted Answer

Nonconvulsive status epilepticus pattern

Answer

Nonconvulsive status epilepticus (NCSE) on continuous EEG is a medical emergency requiring immediate neurologist notification and treatment.
