A nurse is assessing a client following the administration of an initial dose of captopril. Which of the following findings indicates an anaphylactic response?

Choice A reason: Administering oxygen at 2 L/min is appropriate for clients with emphysema who have hypoxemia. Oxygen therapy should be titrated based on the client's oxygen saturation levels to avoid suppressing the respiratory drive.

Choice B reason: The use of incentive spirometry is beneficial for clients with emphysema as it encourages deep breathing and helps prevent atelectasis. It is an appropriate intervention to include in the plan of care.

Choice C reason: Breathing exercises for clients with emphysema typically focus on prolonging the exhalation phase, not the inhalation phase, to improve airway clearance and reduce the work of breathing.

Choice D reason: Limiting fluid intake is not generally recommended for clients with emphysema unless there are specific contraindications. Adequate hydration can help thin secretions and improve mucus clearance.

Choice A reason: Including more cantaloupe in the diet is a good practice for a client on furosemide therapy. Cantaloupe is high in potassium, and furosemide can cause hypokalemia (low potassium levels) as it is a potent diuretic that increases urine production and the excretion of various electrolytes, including potassium. Therefore, consuming foods rich in potassium can help counteract this potential adverse effect.

Choice B reason: Checking the pulse before taking the medication is a general safety measure but does not directly relate to a specific adverse effect of furosemide. While it's important to monitor heart rate, especially in clients with heart failure, this statement does not reflect an understanding of the adverse effects related to furosemide.

Choice C reason: Trying to limit foods that contain salt is an appropriate action for a client with heart failure but is not directly related to an adverse effect of furosemide. Reducing salt intake can help manage heart failure by preventing fluid retention; however, it does not address the specific adverse effects of furosemide therapy.

Choice D reason: Checking blood pressure to ensure it doesn't get too high is important for clients with heart failure but does not indicate an understanding of the adverse effects of furosemide. Furosemide is used to reduce excess fluid in the body, which can lower blood pressure, not increase it. This statement does not reflect an understanding of furosemide's potential to cause electrolyte imbalances.
