A. Breathe deeply, followed by coughing up the sputum. B. Restrict fluids before expectorating the sputum specimen. C. Obtain the specimen before bedtime. D. Avoid mouth care prior to collecting the sputum.

Correct Answer is A

Explanation

Choice A reason:

The correct answer is a) because taking deep breaths followed by coughing helps produce a sputum sample from the lungs, which is necessary for accurate diagnostic testing.

Choice B reason: Restricting fluids before expectorating the sputum specimen is not necessary and may make it more difficult to produce a sample.

Choice C reason: Sputum specimens are best collected in the morning when secretions have accumulated overnight.

Choice D reason: Mouth care should be performed prior to sputum collection to reduce contamination from oral bacteria.
