The nurse educator is reviewing the assessment of cranial nerves. What should the educator identify as the specific instances when cranial nerves should be assessed? Select all that apply
A) When a neurogenic bladder develops
B) When level of consciousness is decreased
C) With brain stem pathology
D) In the presence of peripheral nervous system disease
E) When a spinal reflex is interrupted
Ans: B, C, D
Feedback:
Cranial nerves are assessed when level of consciousness is decreased, with brain stem pathology, or in the presence of peripheral nervous system disease. Abnormalities in muscle tone and involuntary movements are less likely to prompt the assessment of cranial nerves, since these nerves do not directly mediate most aspects of muscle tone and movement.
