Chapter 65 : Assessment of Neurologic Function Questions
Question 1 of 5
A gerontologic nurse educator is providing practice guidelines to unlicensed care providers. Because reaction to painful stimuli is sometimes blunted in older adults, what must be used with caution?
Correct Answer: A
Rationale: Blunted pain response in older adults increases burn or frostbite risk from hot or cold packs. Medications and whirlpool baths are not directly related to this sensory change.
Question 2 of 5
A trauma patient in the ICU has been declared brain dead. What diagnostic test is used in making the determination of brain death?
Correct Answer: B
Rationale: EEG confirms brain death by showing no electrical activity. MRI, CT, and EMG are not standard for this determination.
Question 3 of 5
A patient is scheduled for CT scanning of the head because of recent onset of neurologic deficits. What should the nurse tell the patient in preparation for this test?
Correct Answer: C
Rationale: Lying still during a CT scan ensures clear images. Metal and noise concerns apply to MRI, and fasting is not required for a head CT.
Question 4 of 5
A patient for whom the nurse is caring has positron emission tomography (PET) scheduled. In preparation, what should the nurse explain to the patient?
Correct Answer: D
Rationale: PET scans may cause dizziness or lightheadedness due to tracer inhalation. Blood flow is not limited, iodine allergy applies to CT/MRI, and noise is an MRI concern.
Question 5 of 5
A patient is scheduled for a myelogram and the nurse explains to the patient that this is an invasive procedure, which assesses for any lesions in the spinal cord. The nurse should explain that the preparation is similar to which of the following neurologic tests?
Correct Answer: A
Rationale: Myelography involves contrast injection via lumbar puncture, so preparation is similar. MRI, angiography, and EEG have different preparation requirements.
