A patient with lower back pain is scheduled for myelography using metrizamide (a water-soluble contrast dye). After the test, the nurse should place the patient in which position?
A) Head of the bed elevated 45 degrees
B) Prone
C) Supine with his feet raised
D) Supine with his head lower than his trunk
Ans: A
Feedback: After a myelogram, positioning will depend on the dye injected. When a water-soluble dye such as metrizamide is injected, the head of the bed is elevated to a 45-degree angle to slow the upward dispersion of the dye. The other positions are contraindicated when a water-soluble contrast dye is used. If an air-contrast study was performed, the patient should be positioned supine with his head lower than his trunk.
