Chapter 41 : Assessment of the Nervous System Questions
Question 1 of 5
A nurse assesses a client recovering from a cerebral angiography via the client's right femoral artery. Which assessment should the nurse complete?
Correct Answer: A
Rationale: Cerebral angiography involves threading a catheter through the femoral artery, and the extremity is immobilized post-procedure. Checking bilateral lower extremity pulses ensures adequate circulation. Orthostatic blood pressure readings are not feasible due to bedrest, and fundoscopic examination or gag reflex assessment is unrelated to the procedure.
Question 2 of 5
A nurse obtains a focused health history for a client who is scheduled for magnetic resonance angiography. Which priority question should the nurse ask before the test?
Correct Answer: B
Rationale: Allergies to iodine or shellfish are critical to assess because the contrast used in magnetic resonance angiography may cause a similar allergic reaction. The other options do not affect the safety or outcome of the procedure.
Question 3 of 5
A nurse is caring for a client with a history of renal insufficiency who is scheduled for a computed tomography scan of the head with contrast medium. Which priority intervention should the nurse implement?
Correct Answer: B
Rationale: Intravenous fluids promote excretion of contrast medium, protecting the kidneys in clients with renal insufficiency. Bedrest is not required, gag reflex is unaffected, and an indwelling catheter is unnecessary unless otherwise indicated.
Question 4 of 5
A nurse obtains a focused health history for a client who is scheduled for magnetic resonance imaging (MRI). Which condition should alert the nurse to contact the provider and cancel the procedure?
Correct Answer: D
Rationale: Metal devices like an internal insulin pump can interfere with MRI imaging and be displaced by magnetic forces, necessitating cancellation. CPK, BUN levels, and atrioventricular grafts do not contraindicate MRI.
Question 5 of 5
A nurse teaches a client who is scheduled for a positron emission tomography scan of the brain. Which statement should the nurse include in this client's teaching?
Correct Answer: A
Rationale: Caffeine is a central nervous system stimulant that may alter PET scan results, so it should be avoided for 12 hours prior. Increased fluid intake is unnecessary, cardiac medications should be continued, and metal removal is relevant for MRI, not PET.
