NCLEX PN Exam Practice Test Practice Question
A sputum collection is ordered for an adult. How should the nurse plan to collect the specimen?
Correct Answer: B
Rationale: Collecting a sputum specimen is most effective in the morning when secretions have accumulated overnight, making option B the best choice.
Option A is incorrect because using mouthwash can introduce contaminants that may affect the test results. Option C is not ideal, as collecting sputum throughout the day can lead to inconsistent samples and may dilute the specimen quality. Option D, while promoting hydration is beneficial for overall health, does not specifically enhance sputum collection and could lead to excessive mucus production, complicating the process.
