A nurse is caring for a client who is scheduled to have a magnetic resonance imaging (MRI) scan. The client asks the nurse what to expect during the procedure. Which of the following statements should the nurse make?
"An MRI scan is a short procedure and should take no longer than 30 minutes."
"An MRI scan is not distorted by movement, so you do not have to lie still."
"The MRI contrast dye contains iodine and can cause your skin to itch."
"An MRI scan is very noisy, and you will be allowed to wear earplugs while in the scanner."
The Correct Answer is D
A. MRI scans can vary in duration and may take longer than 30 minutes, depending on the specific procedure and imaging requirements.
B. Movement can distort the images in an MRI scan, so it's crucial for the client to lie as still as possible during the procedure.
C. The contrast dye used in MRIs does not typically contain iodine and is not known to cause skin itching.
D. MRI scanners generate loud noises during operation, and patients are often provided with earplugs or headphones to minimize discomfort from the noise.

Explanation
A. By 24 months, children are typically able to walk, run, and push or pull toys, such as a toy lawnmower, demonstrating gross motor skills and coordination. The inability to push a toy indicates possible delay in gross motor development.
B. Difficulty undressing self involves fine motor and self-care skills, which may vary among children and develop gradually; mild challenges are not necessarily delayed at 24 months.
C. Unscrewing a jar lid requires more advanced fine motor coordination than is expected of most 2-year-olds, so inability to perform this task is within normal developmental limits.
