A neurologist prescribes a magnetic resonance imaging (MRI) of the head STAT for a patient. Which data warrants immediate intervention by the nurse concerning this diagnostic test?
A) Elevated blood pressure.
B) Allergy to shell fish.
C) Right hip replacement.
D) History of atrial fibrillation.
Answer: C) Right hip replacement.
The magnetic field generated by the MRI is so strong that metal-containing items are strongly attracted to the magnet. Because the hip joint is made of metal, a lead shield must be used during the procedure. Elevated blood pressure, an allergy to shell fish, and a history of atrial fibrillation would not affect the MRI.
