Correct Answer is A

Explanation

A. Stabilize the holder when changing tubes. Stabilizing the holder prevents accidental movement of the needle, ensuring proper blood flow into the tube and minimizing discomfort or injury to the patient.

B. Withdraw the holder and tube at the same time: The holder should remain in place until all samples are collected to prevent repeated venipunctures.

C. Replace the tube stopper firmly for each sample: The tube stopper should not be removed or replaced during the procedure.

D. Release the tourniquet after successful venipuncture: The tourniquet should be released after blood flow is established and before the needle is withdrawn, not as the first priority.

A. Obtain the specimen from two parts of the stool B. Obtain the specimen from the middle of the stool. C. Place the whole stool specimen in the specimen container. D. Include any liquid stool

Correct Answer is A

Explanation

A. Obtain the specimen from two parts of the stool. Collecting from two different areas increases the chance of identifying parasites or their ova, as they may not be uniformly distributed in the stool.

B. Obtain the specimen from the middle of the stool: This limits the potential for detecting parasites in other areas of the stool.

C. Place the whole stool specimen in the specimen container: Typically unnecessary and may overfill the container, causing contamination.

D. Include any liquid stool: While liquid stool may be relevant, the sample should still come from multiple areas.
