Chapter 38 Practice Questions - Assessment of the Nervous System Flashcards
The nurse teaches an 80-year-old client with diminished peripheral sensation. Which
statement would the nurse include in this client’s teaching?
a. “Place soft rugs in your bathroom to decrease pain in your feet.”
b. “Bathe in warm water to increase your circulation.”
c. “Look at the placement of your feet when walking.”
d. “Walk barefoot to decrease pressure injuries from your shoes.”
c. “Look at the placement of your feet when walking.”
Older clients with decreased sensation are at risk of injury from the inability to sense changes in terrain when walking. To compensate for this loss, the client is instructed to look at the placement of his or her feet when walking. Throw rugs can slip and increase fall risk. Bath water that is too warm places the client at risk for thermal injury.
The nurse assesses a client’s recent memory. Which statement by the client confirms that recent memory is intact?
a. “A young girl wrapped in a shroud fell asleep on a bed of clouds.”
b. “I was born on April 3, 1967, in Johnstown Community Hospital.”
c. “Apple, chair, and pencil are the words you just stated.”
d. “I ate oatmeal with wheat toast and orange juice for breakfast.”
d. “I ate oatmeal with wheat toast and orange juice for breakfast.”
Asking clients about recent events that can be verified, such as what the client ate for
breakfast, assesses recent memory. Asking clients about certain facts from the past that can be verified assesses remote or long-term memory. Asking the client to repeat words assesses immediate memory
A client is admitted to the emergency department with a probable traumatic brain injury. Which assessment finding would be the priority for the nurse to report to the primary health care provider?
a. Mild temporal headache
b. Pupils equal and react to light
c. Alert and oriented x 3
d. Decreasing level of consciousness
d. Decreasing level of consciousness
A decreasing level of consciousness is the first sign of increasing intracranial pressure, a
potentially severe and possibly fatal complication of a traumatic brain injury (TBI). A mild
headache would be expected for a client having a TBI. Equal reactive pupils and being alert and oriented are normal assessment findings.
A nurse asks a client to take deep breaths during an electroencephalography. The client asks, “Why are you asking me to do this?” How would the nurse respond?
a. “Hyperventilation causes vascular dilation of cerebral arteries, which decreases
electoral activity in the brain.”
b. “Deep breathing helps you to relax and allows the electroencephalograph to obtain
a better waveform.”
c. “Hyperventilation causes cerebral vasoconstriction and increases the likelihood of
seizure activity.”
d. “Deep breathing will help you to blow off carbon dioxide and decreases
intracranial pressures.”
c. “Hyperventilation causes cerebral vasoconstriction and increases the likelihood of
seizure activity.”
Hyperventilation produces cerebral vasoconstriction and alkalosis, which increase the
likelihood of seizure activity. The client is asked to breathe deeply 20 times for 3 minutes. The other responses are not accurate.
A nurse assesses a client recovering from a cerebral angiography via the right femoral artery. Which assessment would the nurse complete?
a. Palpate bilateral lower extremity pulses.
b. Obtain orthostatic blood pressure readings.
c. Perform a funduscopic examination.
d. Assess the gag reflex prior to eating.
a. Palpate bilateral lower extremity pulses.
Cerebral angiography is performed by threading a catheter through the femoral or brachial artery. The extremity is kept immobilized after the procedure. The nurse checks the extremity for adequate circulation by noting skin color and temperature, presence and quality of pulses distal to the injection site, and capillary refill. Clients usually are on bedrest; therefore, orthostatic blood pressure readings cannot be performed. The funduscopic (eye) examination would not be affected by cerebral angiography. The client is not given general anesthesia; therefore, the client’s gag reflex would not be compromised.
When assessing a client who had a traumatic brain injury, the nurse notes that the client is drowsy but easily aroused. What level of consciousness will the nurse document to describe this client’s current level of consciousness?
a. Alert
b. Lethargic
c. Stuporous
d. Comatose
b. Lethargic
The client is categorized as being lethargic because he or she can be easily aroused even
though drowsy. The nurse would carefully monitor the client to determine any decrease in the level of consciousness (LOC).
The nurse is assessing a client diagnosed with trigeminal neuralgia affecting cranial nerve V. What assessment findings will the nurse expect for this client?
a. Expressive aphasia
b. Ptosis (eyelid drooping)
c. Slurred speech
d. Severe facial pain
d. Severe facial pain
Cranial nerve (CN) V is the Trigeminal Nerve which has both a motor and sensory function in the face. When affected by a health problem, the client experiences severely facial pain. Expressive aphasia results from damage to the Broca speech area in the frontal lobe of the brain. Ptosis can result from damage to CN III and slurred speech often occurs from eitherdamage to several cranial nerves or from damage to the motor strip in the frontal lobe of the brain.
The nurse is performing an assessment of cranial nerve III. Which testing is appropriate?
a. Pupil constriction
b. Deep tendon reflexes
c. Upper muscle strength
d. Speech and language
a. Pupil constriction
CN III is the oculomotor nerve which controls eye movement, pupil constriction, and eyelid movement.
A nurse cares for a client who is experiencing deteriorating neurologic functions. The client states, “I am worried I will not be able to care for my young children.” How would the nurse respond?
a. “Caring for your children is a priority. You may not want to ask for help, but you
really have to.”
b. “Our community has resources that may help you with some household tasks so
you have energy to care for your children.”
c. “You seem distressed. Would you like to talk to a psychologist about adjusting to
your changing status?”
d. “Can you tell me more about what worries you, so we can see if we can do
something to make adjustments?”
d. “Can you tell me more about what worries you, so we can see if we can do
something to make adjustments?”
Investigate specific concerns about situational or role changes before providing additional information. The nurse would not tell the client what is or is not a priority for him or her. Although community resources may be available, they may not be appropriate for the patient. Consulting a psychologist would not be appropriate without obtaining further information from the client related to current concerns.
A nurse plans care for a 77-year-old client who is experiencing age-related
peripheral sensory perception changes. Which intervention would the nurse include in this client’s plan of care?
a. Provide a call button that requires only minimal pressure to activate.
b. Write the date on the client’s white board to promote orientation.
c. Ensure that the path to the bathroom is free from clutter.
d. Encourage the client to season food to stimulate nutritional intake.
c. Ensure that the path to the bathroom is free from clutter.
Dementia and confusion are not common phenomena in older adults. However, physical impairment related to illness can be expected. Providing opportunities for hazard-free ambulation will maintain strength and mobility (and ensure safety). Providing a call button, providing the date, and seasoning food do not address the client’s impaired sensory perception
After teaching a patient who is scheduled for magnetic resonance imaging (MRI), the nurse assesses the client’s understanding. Which statement indicates client understanding of the teaching?
a. “I must increase my fluids because of the dye used for the MRI.”
b. “My urine will be radioactive so I should not share a bathroom.”
c. “My gag reflex will be tested before I can eat or drink anything.”
d. “I can return to my usual activities immediately after the MRI.”
d. “I can return to my usual activities immediately after the MRI.”
No postprocedure restrictions are imposed after MRI. The client can return to normal
activities after the test is complete. There are no dyes or radioactive materials used for the MRI; therefore, increased fluids are not needed and the client’s urine would not be
radioactive. The procedure does not impact the client’s gag reflex.
A nurse performs an assessment of pain discrimination on an older adult. The client correctly identifies, with eyes closed, a sharp sensation on the right hand when touched with a pin. Which action would the nurse take next?
a. Touch the pin on the same area of the left hand.
b. Contact the primary health care provider with the assessment results.
c. Ask the client about current and past medications.
d. Continue the assessment on the client’s feet and legs.
a. Touch the pin on the same area of the left hand.
If testing is begun on the right hand and the client correctly identifies the pain stimulus, thenurse would continue the assessment on the left hand. This is a normal finding and does not need to be reported to the provider, but instead documented in the client’s medical record. Medications do not need to be assessed in response to this finding. The nurse would assess the left hand prior to assessing the feet.
A nurse is teaching a client with cerebellar function impairment. Which statement would the nurse include in this client’s discharge teaching?
a. “Connect a light to flash when your door bell rings.”
b. “Label your faucet knobs with hot and cold signs.”
c. “Ask a friend to drive you to your follow-up appointments.”
d. “Use a natural gas detector with an audible alarm.”
c. “Ask a friend to drive you to your follow-up appointments.”
Cerebellar function enables the client to predict distance or gauge the speed with which one is approaching an object, control voluntary movement, maintain equilibrium, and shift from one skilled movement to another in an orderly sequence. A client who has cerebellar function impairment should not be driving. The client would not have difficulty hearing, distinguishing between hot and cold, or smelling.
Which statement would the nurse include when teaching the assistive personnel (AP) about how to care for a client with cranial nerve II impairment?
a. “Tell the client where food items are on the breakfast tray.”
b. “Place the client in a high-Fowler position for all meals.”
c. “Make sure the client’s food is visually appetizing
d. “Assist the client by placing the fork in the left hand.”
a. “Tell the client where food items are on the breakfast tray.”
Cranial nerve II, the optic nerve, provides central and peripheral vision. A patient who has cranial nerve II impairment will have decreased visual acuity, so the AP would tell the client where different food items are on the meal tray. The other options are not appropriate for client with cranial nerve II impairment.
A nurse prepares a client for lumbar puncture (LP). Which assessment finding would alert the nurse to contact the primary health care provider?
a. Shingles infection on the client’s back
b. Client is claustrophobic
c. Absence of intravenous access
d. Paroxysmal nocturnal dyspnea
a. Shingles infection on the client’s back
An LP would not be performed if the client has a skin infection at or near the puncture site because of the risk of cerebrospinal fluid infection. A nurse would want to notify the primary health care provider if shingles were identified on the client’s back. If a client has shortness of breath when lying flat, the LP can be adapted to meet the client’s needs. Claustrophobia, absence of IV access, and paroxysmal nocturnal dyspnea have no impact on whether an LP can be performed.
A nurse assesses a patient who is recovering from a lumbar puncture (LP). Which
complication of this procedure would alert the nurse to urgently contact the primary health care provider?
a. Weak pedal pulses
b. Nausea and vomiting
c. Increased thirst
d. Hives on the chest
b. Nausea and vomiting
The nurse would immediately contact the provider if the client experiences a severe headache, nausea, vomiting, photophobia, or a change in level of consciousness after an LP, which are all signs of increased intracranial pressure. Weak pedal pulses, increased thirst, and hives are not complications of an LP.
