A nurse is teaching pursed-lip breathing to a client who has COPD. Which of the following instructions should the nurse include in the teaching?
"Lie down while practicing pursed-lip breathing.".
"Exhale slowly through your mouth.".
"Inhale through pursed lips.".
"Puff your cheeks when exhaling.".
The Correct Answer is B
Choice A rationale:
Lying down while practicing pursed-lip breathing is not the correct instruction. Pursed-lip breathing is usually performed in a sitting or standing position. Lying down can restrict lung expansion and may not effectively support the purpose of this breathing technique, which is to improve airway pressure and reduce air trapping.
Choice B rationale:
"Exhale slowly through your mouth" is the correct instruction for pursed-lip breathing. This technique involves inhaling through the nose for a count of two and exhaling slowly and steadily through pursed lips for a count of four. The goal is to promote better exhalation, prevent airway collapse, and improve oxygen exchange. The rationale behind this choice is grounded in the mechanics of pursed-lip breathing, which helps create backpressure in the airways, maintaining them open and aiding in proper exhalation.
Choice C rationale:
Inhaling through pursed lips contradicts the proper sequence of pursed-lip breathing. The technique involves inhaling through the nose and exhaling through pursed lips. Inhaling through pursed lips would not provide the intended benefits of the technique.
Choice D rationale:
"Puff your cheeks when exhaling" is not the correct instruction. Puffing the cheeks during exhalation does not contribute to the effectiveness of pursed-lip breathing. This action could potentially impede proper exhalation and defeat the purpose of the technique, which is to control airflow and improve breathing efficiency.

Correct Answer is D
Explanation
Choice A rationale:
Using a 5-mL syringe to flush the catheter is not the best choice. Central venous access devices typically require a larger syringe for flushing to prevent excessive pressure and potential damage to the catheter. A smaller syringe like the 5-mL syringe can create higher pressure, which could cause complications.
Choice B rationale:
Changing the site dressing and stabilization device every 24 hours is not the recommended practice. The dressing and stabilization device should be changed according to facility policy and as needed, but a rigid 24-hour schedule is not necessary and might increase the risk of infection due to unnecessary exposure.
Choice C rationale:
Expecting blood to appear in the catheter lumen after flushing is incorrect. Blood in the catheter lumen after flushing could indicate complications such as a dislodged catheter or other issues requiring immediate attention. The catheter should ideally remain patent without the presence of blood.
Choice D rationale:
This is the correct choice. Using chlorhexidine solution to clean the catheter is an evidence-based practice to prevent infection at the insertion site. Chlorhexidine has broad-spectrum antimicrobial properties and helps reduce the risk of catheter-related infections.
Correct Answer is B
Explanation
Choice A rationale:
Moving the client using a slider board might be appropriate for transferring clients with relatively lower weight and mobility challenges. However, in this scenario, where the client weighs 136 kg (300 lb), a more advanced transfer method is necessary to ensure the safety of both the client and the healthcare providers.
Choice B rationale:
Using an air-assisted transfer device is suitable for transferring clients with higher weight, as it helps reduce friction and strain during the transfer process. This approach ensures a smoother transfer and minimizes the risk of injury to both the client and the assistive personnel.
Choice C rationale:
Raising the bed to 5 cm (2 in) above the level of the stretcher might not provide enough clearance for a safe transfer. Additionally, the use of assistive devices is more appropriate for transferring clients with significant weight, rather than relying solely on adjusting the bed height.
Choice D rationale:
Positioning the head of the bed at 25° prior to the transfer is not directly relevant to the process of transferring a client from a bed to a stretcher. The focus should be on using appropriate equipment and techniques for safe and efficient transfer, especially considering the client's weight.
