CNA Basic Nursing Skills 20 2

Question 1

When collecting a clean-catch urine specimen, what instruction should the CNA give the resident?

Accepted Answer

Clean the urethral area, begin urinating into the toilet, then collect the midstream urine in the container

Answer

A midstream clean-catch specimen reduces contamination from periurethral bacteria by first cleansing the area and discarding the initial urine stream before collection.

Question 2

A 24-hour urine collection has begun. A resident urinated but the CNA forgot to collect it. What should the CNA do?

Accepted Answer

Discard all collected urine and restart the 24-hour collection, notifying the nurse

Answer

Missing a single void invalidates the entire 24-hour collection because the volume and composition of the urine collected will be incomplete and inaccurate.

Question 3

How should a stool specimen be collected?

Accepted Answer

Have the resident defecate into a clean container or hat, then transfer a small amount using the applicator provided

Answer

The resident defecates into a collection hat or clean container; a small amount is transferred with the applicator to the specimen cup to avoid contamination from toilet water.

Question 4

A resident needs a sputum specimen. When is the best time to collect it?

Accepted Answer

In the morning upon waking, before eating or oral hygiene

Answer

Sputum is most concentrated and easiest to expectorate in the morning before oral hygiene or eating, providing the best specimen quality.

Question 5

Which of the following is essential when labeling a specimen before sending it to the laboratory?

Accepted Answer

The resident's full name, date of birth, date and time of collection, and type of specimen

Answer

Complete, accurate labeling prevents specimen mix-ups and ensures results are matched to the correct resident.
