Chapter 36 : Introduction to the Nervous System Questions
Question 1 of 5
The nurse is assessing the throat of a client with throat pain. In asking the client to stick out the tongue, the nurse is also assessing which cranial nerve?
Correct Answer: D
Rationale: Assessment of the movement of the tongue is related to cranial nerve XII, the hypoglossal nerve. Cranial nerve I is the olfactory nerve. Cranial nerve V is the trigeminal nerve responsible for sensation to the face and chewing. Cranial nerve XI is the spinal or accessory nerve responsible for head and shoulder movement.
Question 2 of 5
The nurse is assessing the assigned client's level of consciousness during morning rounds. The nurse speaks the client's name, strokes the client's hand, and moves the client's shoulder. There is a delay, and then the client states, 'What do you want?' Which level of consciousness should the nurse document?
Correct Answer: C
Rationale: Somnolent or lethargy means that the client is drowsy or sleepy at inappropriate times. This is an improvement from the stuporous state, which includes arousing the client only with vigorous and repeated stimulation. A client that is conscious is alert and responds to stimulation immediately. A client is documented as semicomatose when the client only responds to superficial, relatively mild, painful stimuli.
Question 3 of 5
The nurse scores the client's level of consciousness (LOC) using the Glasgow Coma Scale. Which score should indicate to the nurse that the client needs emergency attention?
Correct Answer: A
Rationale: A score of 9 indicates that the client needs emergency attention. Scores greater than or equal to 11 are considered within normal range.
Question 4 of 5
The physician's office nurse is caring for a client who has a history of a cerebral aneurysm. Which diagnostic test does the nurse anticipate to monitor the status of the aneurysm?
Correct Answer: D
Rationale: The nurse would anticipate a cerebral angiography, which detects distortion of the cerebral arteries and veins. A myelogram detects abnormalities of the spinal canal. An electroencephalogram records electrical impulses of the brain. An echoencephalography is an ultrasound of the structures of the brain.
Question 5 of 5
The nurse is caring for a client with a significant allergy history to various medications and shellfish. Because the client needs to have a diagnostic study with contrast, which medication classification is anticipated?
Correct Answer: B
Rationale: Clients with an allergy history are administered a pretest dose of an antihistamine. Antihistamines block histamine receptors and reduce the manifestations of an allergic reaction. The other options are not administered in the pretest period.
