An older male client who fell down several stairs 4-hours ago is scheduled for magnetic resonance imaging (MRI). What information should the practical nurse (PN) obtain from the client?

Correct Answer: B. Rationale: A. The last time food was consumed may be relevant for some medical procedures but isn't directly related to an MRI. B. Knowing the presence of a metal implant is crucial before an MRI due to potential interference with the machine. C. History of the previous myelogram might be relevant but is not as critical for an MRI. Allergy to iodine-based dyes is more pertinent for procedures like a CT scan with contrast, not necessarily an MRI.
