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?
- A. Cranial nerve I
- B. Cranial nerve V
- C. Cranial nerve XI
- D. Cranial nerve XII
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.

A client is waiting in a triage area to learn the medical status of family members following a motor vehicle accident. The client is pacing, taking deep breaths, and handwringing. Considering the effects in the body systems, what does the nurse anticipate the liver will do?
- A. Cease function and shunt blood to the heart and lungs.
- B. Convert glycogen to glucose for immediate use.
- C. Produce a toxic by-product in relation to stress.
- D. Maintain a basal rate of functioning.
Correct Answer: B
Rationale: When the body is under stress, the sympathetic nervous system is activated to ready the body for action. The effect of the body is to mobilize stored glycogen to glucose to provide additional energy for body action.
The nurse is caring for a client in the emergency department with a diagnosis of head trauma secondary to a motorcycle accident. The nurse aide is assigned to clean the client's face and torso. Which action by the nurse aide would prompt the nurse to provide further instruction?
- A. Using mild soapy water to clean the face.
- B. Moving the client's head to clean behind the ears.
- C. Cleaning the eye area from the inner to outer eye area.
- D. Cleaning the neck and upper chest area.
Correct Answer: B
Rationale: Further instruction would be provided to the nurse aide when the nurse aide attempted to move the client's head to clean behind the ears. There should be no movement of the client's head when there is a history of head trauma. Cleaning the client's face with soapy water, cleaning the eye area, and cleaning the neck and upper chest are all appropriate actions completed by the nurse aide.
The nurse provides care for a client with a deteriorating neurologic status. The nurse collects data at the beginning of the shift that reveals a falling blood pressure (BP) and heart rate (HR), and the client makes no motor response to stimuli. Which documentation of neuromuscular status is most appropriate?
- A. Flaccidity
- B. Abnormal posture
- C. Weak muscular tone
- D. Decorticate posturing
Correct Answer: A
Rationale: The nurse should document flaccidity when the client makes no motor response to stimuli. Clients with impaired cerebral function manifest abnormal posturing, which is documented by the nurse as either decorticate posturing (decorticate rigidity), a position in which the arms are flexed, fists are clenched, and the legs are extended or decerebrate posturing (decerebrate rigidity), when the extremities are stiff and rigid. Muscle tone is documented using a scale of 0 to 5; therefore, weak muscular tone is not the most appropriate documentation.
The nurse collects data regarding a client's ability to detect sensation in the upper extremity. Which nursing action(s) is appropriate? Select all that apply.
- A. Place a warm cotton ball on the client's arm.
- B. Use a safety pin to stroke the client's fingers.
- C. Use a needle to introduce a prick to the client's skin.
- D. Drag a tube filled with cold water on the client's arm.
- E. Place a tube filled with warm water on the client's hand.
Correct Answer: A,B,D,E
Rationale: The nurse evaluates the extremities for sensitivity to heat, cold, touch, and pain. Various objects can be used by the nurse for this purpose, including cotton balls and tubes filled with hot or cold water. Sharp objects may be used but should not pierce the skin; therefore, it is appropriate for the nurse to stroke the client's fingers with a safety pin but not to prick the skin with a needle.
A client presents to the emergency department status postseizure. The health care provider wants to measure CSF pressure. What test might be ordered on this client?
- A. Lumbar puncture
- B. Echoencephalography
- C. Nerve conduction studies
- D. EMG
Correct Answer: A
Rationale: Changes in CSF occur in many neurologic disorders. A lumbar puncture (spinal tap) is performed to obtain samples of CSF from the subarachnoid space for laboratory examination and to measure CSF pressure. Echoencephalography records the electrical impulses generated by the brain. Nerve conduction studies measure the speed with which the nerve impulse travels along the peripheral nerve. Electromyography studies the changes in the electrical potential of muscles and the nerves supplying the muscles.
