A phlebotomist should instruct a patient to take which of the following actions when providing a sputum specimen?

Rationale

Take a deep breath and then expectorate.

To provide a proper sputum specimen, the phlebotomist should instruct the patient to take a deep breath and then expectorate, as this method ensures that the sample is derived from the lungs and contains the necessary respiratory secretions for accurate analysis.

A (Collect the stool directly into a sterile container.) YOUR ANSWER

This option is incorrect because stool collection is unrelated to sputum samples, which are specifically obtained from the respiratory system. Sputum pertains to mucus expelled from the lungs, whereas stool pertains to waste material from the gastrointestinal tract.

B (Discard the first urine of the day and collect for 24 hr.) YOUR ANSWER

This choice refers to a 24-hour urine collection procedure, which is not applicable to sputum specimens. Sputum collection focuses on respiratory secretions rather than urine, making this instruction irrelevant for the task at hand.

C (Aggressively swab the inside of the cheek.) YOUR ANSWER

Swabbing the inside of the cheek is a method used for collecting oral samples or DNA, not for sputum. Sputum requires expectoration from the lungs, and cheek swabbing does not yield the necessary respiratory material for analysis.

D (Take a deep breath and then expectorate.) CORRECT

This is the correct choice as it directly pertains to the appropriate technique for obtaining a sputum specimen. Taking a deep breath helps to clear the airways, allowing the patient to cough up mucus from the lungs effectively.

Conclusion

For accurate sputum specimen collection, the patient must be guided to take a deep breath and expectorate. This method ensures that the sample is representative of the respiratory tract, which is critical for diagnostic testing. The other options mistakenly relate to different bodily fluids or collection methods, thus failing to address the specific requirements for sputum analysis.
