Question 1

Which type of urine specimen is most commonly requested for routine urinalysis?

Random specimen

Question 2

When collecting a throat swab for rapid strep testing, where should the swab be applied?

Accepted Answer

The posterior pharynx and tonsillar area

Answer

The swab should be rubbed firmly over the posterior pharynx and tonsillar pillars where Group A Streptococcus colonizes, avoiding the tongue and buccal mucosa.

Question 3

What is the proper protocol for labeling a 24-hour urine collection container?

Accepted Answer

Patient name, start date/time, end date/time, and preservative type

Answer

A 24-hour urine container must be labeled with the patient's full identification, the exact start and end times of collection, and any preservative added.

Question 4

A sputum specimen for culture should ideally be collected at what time?

Accepted Answer

Early morning before eating or drinking

Answer

Early morning sputum specimens are preferred because secretions accumulate overnight, yielding a more concentrated sample with higher organism counts.

Question 5

Which preservative is typically used in a 24-hour urine collection for vanillylmandelic acid (VMA)?

Accepted Answer

Hydrochloric acid (HCl)

Answer

Hydrochloric acid (HCl) is used as a preservative for VMA collections because it maintains an acidic pH that prevents degradation of catecholamine metabolites.
