A client with a suspected lower respiratory tract infection requires a sputum specimen for culture and sensitivity testing. To minimize the risk of sample contamination with oral flora, which sequence of steps should the practical nurse follow? Arrange the actions in the correct chronological order.
- 1Instruct the client to rinse the mouth with plain water without swallowing.
- 2Ask the client to take several slow, deep breaths to expand the lungs.
- 3Direct the client to perform a deep, forceful cough to mobilize lower airway secretions.
- 4Have the client expectorate the mobilized secretions directly into the sterile container.
- 5Secure the lid on the container immediately and apply the client's identification label.
Cevap
The correct sequence begins with oral preparation (rinsing), followed by lung expansion (deep breathing), mobilization of secretions (coughing), collection (expectorating), and finally securing the specimen (sealing and labeling).
Following the chronological order of rinsing the mouth, performing deep breathing, coughing deeply, expectorating into the container, and immediately sealing it ensures the specimen is uncontaminated and accurately reflects the lower respiratory tract environment.
