Correct Answer is D
Explanation
A. Has a Foley catheter in place: Not required for an MRI. Foley catheters made of metal-free materials do not interfere with MRI imaging.
B. Has drunk a liter of fluid: This is not relevant for an MRI, unless specifically indicated for contrast imaging, which is uncommon.
C. Has eaten a meal: Eating or fasting is not typically relevant for MRI procedures unless sedation or contrast media requires it.
D. Is not wearing anything with metal: Metal objects can interfere with the MRI’s magnetic field and pose a safety risk to the patient and equipment. Even small objects like jewelry, piercings, or implanted devices must be addressed to prevent harm.
Correct Answer is A
Explanation
A. Pass a small amount of urine into the toilet and then collect the specimen. This technique ensures that bacteria or debris from the urethra are flushed out before the sample is collected, providing a clean-catch specimen for analysis.
B. Void until the bladder is almost empty and then collect the end portion: This would result in a less accurate sample, as bacteria or debris might accumulate.
C. Let a few drops of urine dribble into the specimen cup: This does not provide enough urine for analysis.
D. Begin voiding into the specimen cup: This may contaminate the sample with bacteria from the external genitalia.
