Chapter 65 : Assessment of Neurologic Function Questions
Question 1 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 2 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 3 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 4 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.
Question 5 of 5
The nurse is doing an initial assessment on a patient newly admitted to the unit with a diagnosis of cerebrovascular accident (CVA). The patient has difficulty copying a figure that the nurse has drawn and is diagnosed with visual-receptive aphasia. What brain region is primarily involved in this deficit?
Correct Answer: B
Rationale: Visual-receptive aphasia, involving difficulty copying figures, is linked to the parietal-occipital area, which integrates visual and spatial processing. Temporal lobe damage affects auditory comprehension, and frontal areas impact expressive speech.
