Final answer:
UDS performed on a patient who eats poppy seed bagels may yield false positives for opioids.
Step-by-step explanation:
UDS, or urine drug screening, performed on a patient who eats poppy seed bagels may yield false positives for opioids. Poppy seeds come from the opium poppy plant, which contains small amounts of morphine and codeine. These substances can be detected in urine drug tests and may lead to a false positive result for opioids. It is important for healthcare providers to take this into consideration when interpreting UDS results and to confirm any positive findings through further testing.
