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?
Last time food was consumed.
Presence of a metal implant.
History of previous myelogram.
Allergy to iodine-based dyes.
The Correct Answer is B
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.

Correct Answer is C
Explanation
A. Complete blood count: Primarily measures the number of blood cells and their types. It does not directly assess the effectiveness of warfarin.
B. Creatinine clearance: Evaluates kidney function and doesn't directly reflect the efficacy of warfarin.
C. Prothrombin time (PT): Measures the time taken for blood to clot, an essential indicator for monitoring anticoagulation therapy like warfarin.
D. Serum troponin levels: Assesses cardiac damage and is not indicative of warfarin's effectiveness in managing atrial fibrillation.
Correct Answer is C
Explanation
A. Oriented x 3. - The client must recall the time, day, date, location, and reason for being there to be considered oriented x 3. As the client can only remember his name and location, it does not fulfill the criteria for oriented x 3.
B. Oriented x 1. - This is inaccurate as the patient is oriented in two aspects: person and place.
C. Oriented x 2. - The client recalls their name and place, hence is oriented in two aspects. This is therefore accurate.
D. Oriented x 4. - This would require the client to recall all four aspects of orientation (time, day, date, location, and reason for being there), which the client did not demonstrate in this scenario.
