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:
Planning to insert an oral airway if seizure activity begins is not a suitable intervention for a client with a history of seizures. During a seizure, it's essential to protect the client from injury by preventing them from aspirating secretions or foreign objects. However, inserting an oral airway during an active seizure can be dangerous and lead to injury.
Choice B rationale:
Administering pain medication after the seizure is not a priority intervention. While some clients may experience muscle soreness or discomfort following a seizure, the primary focus during and immediately after a seizure is ensuring the client's safety and preventing injury. Pain medication can be considered later if necessary.
Choice C rationale:
The correct choice is to pad the side rails of the client's bed with blankets. This intervention aims to prevent injury if the client experiences a seizure and comes into contact with the bed rails. Padding the side rails can reduce the risk of trauma and minimize the potential for harm during a seizure episode.
Choice D rationale:
Placing the client in a supine position during a seizure is not recommended. It's important to position the client on their side (lateral recumbent position) during a seizure to allow any oral secretions or vomit to drain from the mouth, reducing the risk of aspiration. Placing the client supine could obstruct the airway and increase the risk of aspiration.
