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. Encouraging the client to use the spirometer before analgesia can increase discomfort and reduce effort, leading to ineffective deep breathing. Pain control should be optimized first to promote participation and proper technique.
B. Delaying instruction for several hours postpones an important postoperative intervention that helps prevent complications such as atelectasis. Early and consistent use of the spirometer is essential for optimal recovery.
C. Administering a PRN analgesic first improves comfort, allowing the client to take deeper breaths and use the spirometer effectively. This approach supports both pain management and respiratory function, making it the best choice.
D. Reassuring the client that the spirometer is not painful dismisses the client’s concern and does not address the need for pain control. Postoperative clients often experience pain with deep breathing, so appropriate analgesia is necessary.
