Correct Answer: A

Rationale: The correct answer is A: Constant bubbling in the water seal chamber. Constant bubbling in the water seal chamber can indicate an air leak, which compromises the integrity of the chest tube system and should be reported to the provider for immediate intervention. Choices B, C, and D are incorrect. Intermittent bubbling in the suction control chamber is an expected finding indicating that the system is working appropriately. Tidaling in the water seal chamber is a normal fluctuation of fluid level with inspiration and expiration, indicating that the system is functioning correctly. Drainage of 75 mL in the first 24 hours is within the expected range for chest tube drainage and does not require immediate reporting unless accompanied by other concerning symptoms.

Correct Answer: B

Rationale: Pursed-lip breathing is a beneficial technique for clients with COPD as it helps control shortness of breath and improves oxygenation. This technique involves inhaling slowly through the nose and exhaling through pursed lips, which helps keep airways open. Option A is incorrect as breathing rapidly through the mouth when using the incentive spirometer can lead to hyperventilation. Option C is incorrect because it is important for clients with COPD to stay hydrated by drinking fluids between meals, but not during meals which can cause bloating and discomfort. Option D is incorrect as diaphragmatic breathing, though beneficial, is not the preferred technique for managing dyspnea in COPD; pursed-lip breathing is more effective.

Correct Answer: A

Rationale: The correct answer is A: 'I will avoid crowded places to reduce my risk of infection.' When taking prednisone, clients should avoid crowded places to reduce the risk of infection due to its immunosuppressive effects. Choice B is incorrect because prednisone is usually taken with food to reduce stomach upset. Choice C is incorrect because clients should not stop taking prednisone abruptly, even if they experience nausea. Choice D is incorrect because prednisone should be tapered off gradually under healthcare provider guidance instead of being stopped abruptly after 2 weeks.

Correct Answer: B

Rationale: The correct statement the nurse should make is that dehydration can increase the risk of preterm labor. Dehydration reduces amniotic fluid and uterine blood flow, potentially leading to preterm contractions. Choice A is incorrect because dehydration is not treated with calcium supplements but rather with adequate fluid intake. Choice C is incorrect as dehydration does not directly increase gastroesophageal reflux. Choice D is incorrect as dehydration is not caused by decreased hemoglobin and hematocrit levels but rather by insufficient fluid intake or excessive fluid loss.

Correct Answer: A

Rationale: A potassium level of 5.0 mEq/L is at the upper limit of normal and should be monitored closely in clients taking spironolactone, which is potassium-sparing. Elevated potassium levels can lead to hyperkalemia, especially in individuals on potassium-sparing diuretics like spironolactone. Monitoring and reporting high potassium levels are crucial to prevent potential complications such as cardiac arrhythmias. Blood pressure (choice B), sodium level (choice C), and calcium level (choice D) are not directly related to the use of spironolactone and do not require immediate reporting in this scenario.
