Scenario 1

A patient with a urine creatinine of 25 mg/dL who has reportedly been taking codeine has codeine present in her urine but no morphine present. Which statement is true?

Please select the single best answer

	The urine is adulterated, so the confirmation is not reliable
	The parent drug is detected, which is expected. The metabolite morphine need not be detected to call the patient compliant.
	A positive result for morphine would not be expected if codeine was taken.
	Without the presence of both codeine and morphine, it can be concluded that the patient is noncompliant.
