Question 20

Take a deep breath and then expectorate.

Patients should be instructed to take a deep breath and then expectorate to ensure that the sputum specimen is collected properly. This method helps in obtaining a sample from deeper in the lungs, which is essential for accurate testing.

A) Collect the stool directly into a sterile container.

This option is incorrect because it pertains to stool collection rather than sputum collection. Sputum specimens require a different procedure that focuses on respiratory secretions, not gastrointestinal samples.

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

This option is also incorrect as it relates to urine collection for a timed test rather than the process of collecting a sputum specimen. Sputum collection does not involve urine, making this choice irrelevant.

C) Aggressively swab the inside of the cheek.

This option is incorrect because it describes a method for obtaining a buccal swab, which is not appropriate for sputum collection. Sputum requires a sample from the respiratory tract, not the oral cavity.

D) Take a deep breath and then expectorate.

This option is correct as it describes the proper technique for sputum collection. By taking a deep breath, the patient can bring up mucus from the lungs, providing a suitable specimen for analysis.

Conclusion

The correct answer, "Take a deep breath and then expectorate," is essential for ensuring an effective sputum collection process. The other options either relate to different types of sample collection or do not provide the necessary method for obtaining a respiratory specimen, confirming that D is the only appropriate choice.
