Chapter 65 Questions
Question 1 of 5
A patient is brought to the ER following a motor vehicle accident in which he sustained head trauma. Preliminary assessment reveals a vision deficit in the patients left eye. The nurse should associate this abnormal finding with trauma to which of the following cerebral lobes?
Correct Answer: B
Rationale: The occipital lobe is responsible for visual processing. Trauma to this area can result in vision deficits. The temporal lobe handles auditory functions, the parietal lobe manages sensory integration, and the frontal lobe governs motor and cognitive functions.
Question 2 of 5
A patient scheduled for magnetic resonance imaging (MRI) has arrived at the radiology department. The nurse who prepares the patient for the MRI should prioritize which of the following actions?
Correct Answer: B
Rationale: MRI uses strong magnetic fields, making removal of metal objects critical to prevent injury or image distortion. Withholding stimulants applies to EEG, voiding to lumbar puncture, and IV contrast to CT scans.
Question 3 of 5
A gerontologic nurse planning the neurologic assessment of an older adult is considering normal, agerelated changes. Of what phenomenon should the nurse be aware?
Correct Answer: B
Rationale: Aging reduces cerebral blood flow, impacting neurologic function. Deep tendon reflexes may decrease, cerebral metabolism declines, and pain sensitivity often diminishes in older adults.
Question 4 of 5
The nurse has admitted a new patient to the unit. One of the patients admitting orders is for an adrenergic medication. The nurse knows that this medication will have what effect on the circulatory system?
Correct Answer: B
Rationale: Adrenergic medications stimulate the sympathetic nervous system, increasing heart rate and force. Thin saliva and decreased BP are parasympathetic effects, while bronchodilation, not constriction, occurs.
Question 5 of 5
A nurse is assessing reflexes in a patient with hyperactive reflexes. When the patients foot is abruptly dorsiflexed, it continues to beat two to three times before settling into a resting position. How would the nurse document this finding?
Correct Answer: C
Rationale: Clonus is characterized by rhythmic muscle contractions, such as foot beating after dorsiflexion, indicating hyperactive reflexes. Rigidity is increased muscle tone, flaccidity is lack of tone, and ataxia is uncoordinated movement.
