The nurse is caring for a client with emphysema who is mildly dyspneic after ambulation. Which instruction should the nurse provide to the client to improve gas exchange?
Lay down on each side with knees bent and breathe from abdomen.
Increase breathing rate for a full 30 seconds.
Raise hands above the head to expand the diaphragm.
Draw air in through nose and exhale slowly through pursed lips.
The Correct Answer is D
Choice A rationale
Laying down on each side with knees bent and breathing from the abdomen is not an effective technique for improving gas exchange in emphysema patients.
Choice B rationale
Increasing the breathing rate for a full 30 seconds can lead to hyperventilation and is not recommended for improving gas exchange.
Choice C rationale
Raising hands above the head to expand the diaphragm is not a recognized technique for improving gas exchange in emphysema patients.
Choice D rationale
Drawing air in through the nose and exhaling slowly through pursed lips is an effective technique for improving gas exchange in emphysema patients. This method helps to keep the airways open longer and improves the removal of trapped air.

Correct Answer is A
Explanation
Choice A rationale
Respiratory acidosis is characterized by elevated levels of carbon dioxide (CO2) in the blood due to impaired ventilation. This accumulation of CO2 leads to a decrease in blood pH, making it more acidic.
Choice B rationale
Hyperventilation leads to a rapid elimination of CO2, which would result in respiratory alkalosis, not acidosis. Therefore, this choice does not support the pathophysiological process of respiratory acidosis.
Choice C rationale
Blood oxygen levels stimulating the respiratory rate is a compensatory mechanism for hypoxemia but does not directly cause respiratory acidosis. This process is more related to respiratory alkalosis.
Choice D rationale
The kidneys do play a role in acid-base balance, but they primarily eliminate acids other than CO2. They do not significantly convert CO2 for elimination, making this choice incorrect.
Correct Answer is C
Explanation
Choice A rationale
Monitoring daily urine output volume is important for assessing fluid balance, but it does not directly address the issue of hypernatremia. Hypernatremia is characterized by high sodium levels in the blood, and monitoring urine output alone will not help in managing sodium intake or identifying sources of excess sodium.
Choice B rationale
Using salt tablets after strenuous exercise is not recommended for clients with hypernatremia. Salt tablets can increase sodium levels further, exacerbating the condition. Hypernatremia requires careful management of sodium intake, and salt tablets would be counterproductive.
Choice C rationale
Reviewing food labels for sodium content is crucial for clients with hypernatremia. This helps them identify and avoid foods high in sodium, which can contribute to elevated sodium levels in the blood. Educating clients on reading food labels empowers them to make informed dietary choices and manage their condition effectively.
Choice D rationale
Drinking plenty of water whenever thirsty is a general recommendation for maintaining hydration, but it does not specifically address hypernatremia. Clients with hypernatremia need to focus on managing their sodium intake and ensuring they do not consume excessive amounts of sodium.
