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 C
Explanation
Choice A rationale:
Verifying placement of a nasogastric tube requires specialized training and knowledge to ensure correct placement and prevent complications. The nurse should retain this task to ensure patient safety.
Choice B rationale:
Evaluating a client's understanding of how to use crutches involves assessing the client's comprehension and ability to use crutches safely and effectively. This task requires nursing judgment and should not be delegated to an assistive personnel.
Choice C rationale:
Replacing the gauze on a skin abrasion is a task that can be safely assigned to an assistive personnel. It involves basic wound care, which typically falls within the scope of practice for assistive personnel. The AP can be trained to follow established protocols for wound cleaning and dressing changes.
Choice D rationale:
Monitoring bowel sounds requires clinical judgment and the ability to recognize variations from the normal range. The nurse should perform this task, as it involves assessing the client's condition and making appropriate decisions based on the findings.
Correct Answer is C
Explanation
Choice A rationale:
The neighbor is not authorized to provide consent for the client's procedure. The durable power of attorney for health care typically designates someone to make medical decisions when the client is unable to do so, but the neighbor's role may not extend to medical procedure consent.
Choice B rationale:
The client's spouse might have a legal standing to make decisions for the client, but the durable power of attorney for health care typically takes precedence over the spouse's decision-making authority in situations where it has been established.
Choice C rationale:
The provider, in this case, the medical doctor or healthcare professional performing the endoscopy, has the authority to obtain consent for the procedure. Informed consent is a crucial ethical and legal requirement, and the provider must ensure that the client or their designated decision-maker understands the procedure, its risks, and benefits before proceeding.
Choice D rationale:
A member of the facility's ethics committee does not typically have the authority to provide consent for a specific medical procedure on behalf of an incapacitated client. The ethics committee's role is to provide guidance on ethical dilemmas and issues but not to provide individual procedural consent.
