A nurse is preparing a client for magnetic resonance imaging (MRI). Which of the following statements should the nurse include when reinforcing teaching?
"Unlike an x-ray, the MRI allows you to move around a bit."
"Your exposure to radiation will be minimal."
"You will not be able to talk to the technician during the procedure."
"You'll have to remove metal objects such as watches and body jewelry."
The Correct Answer is D
A. "Unlike an x-ray, the MRI allows you to move around a bit":
This statement is not accurate. During an MRI, it is important for the client to remain as still as possible to obtain clear images. Movement can result in blurred images.
B. "Your exposure to radiation will be minimal":
This statement is not applicable to MRI, as MRI does not use ionizing radiation. It uses a strong magnetic field and radio waves to generate images, making it different from x-rays in terms of radiation exposure.
C. "You will not be able to talk to the technician during the procedure":
While it is essential for the client to remain still during an MRI, communication with the technician is generally possible through an intercom system. The client may be given instructions and reassurance during the procedure.
D. "You'll have to remove metal objects such as watches and body jewelry":
This is the correct statement. Metal objects can interfere with the magnetic field used in MRI and can pose a safety risk. Therefore, clients are required to remove any metal objects before undergoing an MRI.

Correct Answer is C
Explanation
A. Keeping the client's personal items within reach may be a good practice for convenience but does not directly address the issue of nighttime wandering. Safety and supervision are key considerations.
B. Telling the family that someone should plan to stay with the client might be a temporary solution but may not be sustainable or practical in the long term. Additionally, institutional settings often have policies and resources to address nighttime wandering.
C. Placing the client in a quiet room at the end of the hallway can help minimize disturbances to other residents while providing a safer and more controlled environment. It can also reduce the risk of the client wandering into potentially unsafe areas.
D. Providing bright lighting in the client's room at night may contribute to disorientation and disrupt the sleep-wake cycle. It is generally recommended to maintain a calm and dimly lit environment during nighttime hours to promote rest.
Correct Answer is D
Explanation
A. Aspirin is not primarily prescribed to prevent fever. Its primary mechanism of action is related to its effects on platelets and blood clotting rather than its antipyretic (fever-reducing) properties.
B. While aspirin can provide analgesic (pain-relieving) effects, especially for mild to moderate pain, its use in clients with coronary artery disease is primarily due to its antiplatelet properties rather than its analgesic effects.
C. Aspirin has some anti-inflammatory properties, but in the context of coronary artery disease, its main benefit is related to its antiplatelet function rather than its anti-inflammatory effects.
D. Aspirin is widely prescribed in cardiovascular conditions like coronary artery disease because it inhibits the aggregation of platelets, reducing the risk of blood clot formation. This antiplatelet effect helps in preventing blood clots that could potentially lead to further blockages in the arteries, reducing the risk of complications such as heart attacks or strokes in individuals with heart disease.
