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:
Dysrhythmia refers to irregular heart rhythms and is not associated with the carotid artery. It involves issues with the heart's electrical conduction system.
Choice B rationale:
A cardiac murmur is an abnormal sound heard during the heartbeat cycle, usually indicating turbulent blood flow across heart valves. It's not directly related to the carotid artery.
Choice C rationale:
Hypotension refers to low blood pressure, which might impact blood flow through the carotid artery but wouldn't directly cause the sound known as a bruit.
Choice D rationale:
A bruit heard while auscultating the carotid artery suggests a narrowed arterial lumen. A bruit is a whooshing or blowing sound caused by turbulent blood flow due to arterial narrowing or blockage.
Correct Answer is A
Explanation
Choice A rationale:
During bladder irrigation, the nurse should instill a specific volume of the prescribed irrigation solution into the bladder to facilitate the removal of clots, mucus, or other debris from the urinary catheter and bladder. The recommended volume to instill is usually 400 to 500 mL, which helps to effectively flush out the bladder without overdistending it.
Choice B rationale:
Clamping the drainage tubing distal to the injection port during bladder irrigation is incorrect. The drainage tubing should remain unclamped to allow the irrigation solution to flow into the bladder and facilitate the removal of debris. Clamping the tubing would prevent the solution from entering the bladder and hinder the irrigation process.
Choice C rationale:
Using a syringe with a 19-gauge needle is not relevant to the process of bladder irrigation. Bladder irrigation is typically performed using a specific irrigation kit that includes appropriate tubing and components, not a syringe and needle.
Choice D rationale:
Withdrawing the irrigation solution into the syringe is not a standard procedure during bladder irrigation. The purpose of bladder irrigation is to instill a specific volume of solution into the bladder and then allow it to drain out, flushing the bladder in the process. Drawing the solution back into a syringe after instillation would disrupt the intended irrigation process.
