Correct Answer is ["B","C","D"]

Explanation

A. Void a small amount of urine after external genitalia are cleansed: This applies to midstream clean-catch specimens, not 24-hour urine collection.

B. Empty the bladder into the toilet and begin timing the collection: The first void is discarded, and timing starts afterward.

C. Keep the container on ice if instructed to do so: Some tests require the specimen to remain cool to preserve its integrity.

D. Keep the container refrigerated as needed: Refrigeration may be required depending on the specific test to prevent sample degradation.

E. Save only the first voiding in the morning: The first void is discarded to ensure accurate timing and complete collection for the 24-hour period.

A. Pass a small amount of urine into the toilet and then collect the specimen. B. Void until the bladder is almost empty and then collect the end portion of the voiding in the cup. C. Let a few drops of urine dribble into the specimen cup. D. Begin voiding into the specimen cup.

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.
