A client with COPD reports fatigue during activities of daily living. What intervention should the nurse recommend?

Correct Answer: C

Rationale: The correct answer is C: Rest between activities to conserve energy. This intervention is appropriate for a client with COPD experiencing fatigue as it helps prevent overexertion and conserves energy. Resting between activities allows the client to pace themselves, reducing the risk of worsening symptoms. Performing all activities in the morning (choice A) may not address the fatigue throughout the day. Using oxygen only during strenuous activities (choice B) does not address the underlying issue of energy conservation. Increasing activity level to build endurance (choice D) may lead to further fatigue and exacerbate symptoms. Overall, choice C is the most suitable intervention for managing fatigue in a client with COPD.

Correct Answer: A

Rationale: The correct answer is A: Morning headaches. 1. Sleep apnea causes intermittent pauses in breathing during sleep, leading to low oxygen levels and frequent awakenings, resulting in morning headaches. 2. Frequent nighttime urination (B) is not typically associated with sleep apnea. 3. Unexplained weight loss (C) is not a common symptom of sleep apnea. 4. Persistent dry cough (D) is more commonly associated with conditions like asthma or GERD, not sleep apnea.

Correct Answer: B

Rationale: The correct answer is B: Avoid smoking or open flames near oxygen equipment. This is crucial because oxygen supports combustion and can cause fires. Smoking or having open flames near oxygen equipment can lead to serious accidents. A: Using oxygen only when shortness of breath occurs is incorrect because oxygen therapy should be used as prescribed by the healthcare provider, not just when symptoms are present. C: Setting the oxygen flow rate to 4 L/min at all times is incorrect because the flow rate should be adjusted based on the client's oxygen saturation levels and prescribed by the healthcare provider. D: Storing oxygen tanks in an enclosed space for safety is incorrect because oxygen tanks should be stored in a well-ventilated area, away from heat sources, to reduce the risk of fire.

Correct Answer: B

Rationale: The primary goal of oxygen therapy in pulmonary fibrosis is to maintain tissue oxygenation. Pulmonary fibrosis causes scarring of the lungs, leading to impaired gas exchange and reduced oxygen levels in the blood. Supplemental oxygen helps to ensure that the tissues receive an adequate supply of oxygen, preventing hypoxemia and tissue damage. - A: Oxygen therapy does not cure pulmonary fibrosis but helps manage symptoms. - C: Oxygen therapy may prevent acute exacerbations but may not always prevent the need for mechanical ventilation. - D: While oxygen therapy can improve exercise tolerance temporarily, it does not offer a permanent solution for pulmonary fibrosis.

Correct Answer: B

Rationale: The correct answer is B: Before engaging in exercise. SABAs are used as quick-relief medications to provide immediate relief of asthma symptoms, such as shortness of breath and wheezing. Using the inhaler before exercise helps prevent exercise-induced bronchoconstriction by opening up the airways. Option A is incorrect because using SABA daily at bedtime is not recommended and can lead to overuse. Option C is incorrect as SABA should be used as needed for quick relief, not necessarily after taking a corticosteroid inhaler. Option D is incorrect because SABA should be used not only during severe asthma attacks but also before physical activity to prevent symptoms.
