Question 68

Take a deep breath and then expectorate.

When providing a sputum specimen, the patient should take a deep breath and then expectorate to ensure that the sample is collected from the lungs and is representative of respiratory secretions.

A) Collect the stool directly into a sterile container.

This option is incorrect as it pertains to stool collection, not sputum. A sputum specimen specifically requires respiratory secretions, making this choice irrelevant to the task at hand.

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

This choice is also incorrect because it relates to urine collection protocols, specifically for a 24-hour urine test. Sputum collection has no connection to urine, thus rendering this option unsuitable.

C) Aggressively swab the inside of the cheek.

This option is incorrect as it describes a method for collecting a buccal swab rather than a sputum specimen. Sputum collection requires expectoration from the lungs, and cheek swabbing does not provide the necessary respiratory sample.

D) Take a deep breath and then expectorate.

This option is the correct choice, as it accurately describes the process required for collecting a sputum specimen. Taking a deep breath helps to clear the lungs and makes it easier to produce a sample that is suitable for testing.

Conclusion

The correct answer, "Take a deep breath and then expectorate," is essential for obtaining a valid sputum specimen from the respiratory tract. Options A, B, and C are irrelevant to sputum collection and focus instead on other types of specimen collection, highlighting the importance of specific techniques for different medical tests. Thus, understanding the correct procedure is vital for accurate diagnosis and treatment.
