A nurse is providing teaching to a client who will undergo a magnetic resonance imaging (MRI) scan. Which of the following statements is appropriate to include in the teaching?
"The nurse will ask you to remove any transdermal patches prior to the procedure."
"The nurse will ask you to wear protective eyewear during this procedure."
"You should not have this procedure if you are allergic to iodine."
"You should not have this procedure if you have a tattoo."
The Correct Answer is A
Rationale:
A. "The nurse will ask you to remove any transdermal patches prior to the procedure.": Some transdermal patches contain metallic components that can overheat during an MRI, posing a burn risk. Removing them prevents injury and ensures safety in the strong magnetic field.
B. "The nurse will ask you to wear protective eyewear during this procedure.": Protective eyewear is not necessary for MRI scans, as there is no exposure to bright light or flying debris. This precaution applies more to procedures involving lasers or potential eye hazards.
C. "You should not have this procedure if you are allergic to iodine.": Iodine allergies are a concern with certain CT scans using iodinated contrast, not standard MRIs. MRI contrast agents typically contain gadolinium, which has a different allergy profile.
D. "You should not have this procedure if you have a tattoo.": Tattoos generally do not contraindicate MRI, although some with metallic ink may cause mild skin irritation. This is rare and does not usually prevent the procedure from being performed.

Correct Answer is B
Explanation
Rationale:
A. "Place a pillow under your knees while in bed.": Elevating the knees with a pillow can compress blood vessels and restrict circulation, increasing the risk of venous stasis and deep vein thrombosis.
B. "Participate in range-of-motion exercises.": Performing range-of-motion exercises promotes blood flow in the extremities, prevents venous stasis, and reduces the risk of complications such as deep vein thrombosis, supporting postoperative circulation.
C. "Remain on bed rest for 24 hours following the procedure.": Prolonged immobility can impair circulation and increase the risk of blood clots. Early ambulation and movement are encouraged unless contraindicated by the provider.
D. "Use an incentive spirometer every hour”: While using an incentive spirometer is important for preventing respiratory complications, it primarily promotes lung expansion and does not directly enhance circulation.
Correct Answer is D
Explanation
Rationale:
A. Obtain filterless IV tubing: Blood transfusions require specialized IV tubing with an in-line filter to remove clots and debris. Using filterless tubing would increase the risk of transfusing particulate matter into the client’s bloodstream.
B. Place the blood in a warmer for 1 hr: Blood should only be warmed if specifically prescribed and done using an approved device immediately before administration. Prolonged warming increases the risk of bacterial growth and hemolysis.
C. Use a 24-gauge IV catheter: Packed RBCs should be administered through a larger-bore catheter (typically 18–20 gauge) to allow adequate flow and prevent hemolysis. A 24-gauge catheter is too small for efficient transfusion.
D. Prime IV tubing with 0.9% sodium chloride: Normal saline is the only compatible solution for priming and administering blood products. It prevents clotting and hemolysis while ensuring that the blood flows freely without interacting with other IV solutions.
