The nurse completes a focused assessment and history of a patient who is scheduled for magnetic resonance imaging (MRI). Which data shared by the patient would the nurse need to contact the provider?
Presence of a synthetic silicone mesh stent in a coronary artery.
Allergy to shellfish and iodine.
Contact lenses.
Presence of an internal insulin pump in the abdomen.
The Correct Answer is D
Choice A reason: Presence of a synthetic silicone mesh stent in a coronary artery is not a contraindication for MRI. Silicone is a non-magnetic material that does not interfere with the magnetic field or cause any harm to the patient or the device.
Choice B reason: Allergy to shellfish and iodine is not a contraindication for MRI. Shellfish and iodine are not related to the contrast agent used for MRI, which is usually gadolinium. However, the patient should inform the provider if they have any history of allergic reactions to contrast agents or any other medications.
Choice C reason: Contact lenses are not a contraindication for MRI. Contact lenses are made of plastic or silicone, which are non-magnetic materials that do not interfere with the magnetic field or cause any harm to the patient or the device. However, the patient should remove them before the procedure to avoid any discomfort or irritation.
Choice D reason: Presence of an internal insulin pump in the abdomen is a contraindication for MRI. Insulin pumps are electronic devices that contain metal parts, batteries, and wires, which can be affected by the magnetic field and cause malfunction, damage, or injury to the patient or the device. Therefore, the patient should inform the provider and the MRI technician about the insulin pump and follow their instructions on how to manage it before, during, and after the procedure.

Correct Answer is C
Explanation
Choice A reason: Diabetes mellitus Type 1 is a condition that affects the pancreas and the production of insulin, a hormone that regulates blood sugar levels. It does not directly cause anemia, but it can increase the risk of complications such as infections, ulcers, and nerve damage.
Choice B reason: Peripheral vascular disease is a condition that affects the blood vessels and the circulation of blood to the limbs. It does not directly cause anemia, but it can increase the risk of complications such as clots, wounds, and gangrene.
Choice C reason: Chronic kidney disease is a condition that affects the kidneys and their function of filtering waste and fluids from the blood. It can cause anemia by reducing the production of erythropoietin, a hormone that stimulates the bone marrow to make red blood cells.
Choice D reason: Hypertension is a condition that affects the blood pressure and the force of blood against the artery walls. It does not directly cause anemia, but it can increase the risk of complications such as stroke, heart attack, and kidney damage.
Correct Answer is B
Explanation
Choice A reason: This is incorrect. The foot remaining in the same position prior to stroking the sole of the foot is a normal response in adults. It indicates that the spinal cord and the brain are intact and functioning properly.
Choice B reason: This is correct. Great toe bending upward, and smaller toes fanning outward is an abnormal response in adults. It indicates a positive Babinski reflex, which is a sign of damage to the cerebral cortex or the pyramidal tract. The cerebral cortex is the outer layer of the brain that controls higher functions such as thinking, reasoning, and movement. The pyramidal tract is a bundle of nerve fibers that connects the cerebral cortex to the spinal cord and controls voluntary movements.
Choice C reason: This is incorrect. Great toe bending downward is also a normal response in adults. It indicates that the spinal cord and the brain are intact and functioning properly.
Choice D reason: This is incorrect. The opposite foot assuming the same position as the foot being stroked is not related to the Babinski reflex. It is a phenomenon called mirror movement, which may occur in some people due to genetic or developmental factors. It does not indicate any abnormality in the cerebral cortex.
