A nurse is reviewing a client's laboratory report. The client's ABG levels are pH 7.5, PaCO2 32 mm Hg, and HCO3 24 mEq/L. The nurse should determine that the client has which of the following acid-base imbalances?

Choice A reason: A client who has BPH and reports dysuria is not the highest priority, because dysuria is a common symptom of BPH and does not indicate an acute complication. The nurse should monitor the client's urinary output and provide comfort measures.

Choice B reason: A client who has ulcerative colitis and reports diarrhea is not the highest priority, because diarrhea is a chronic symptom of ulcerative colitis and does not indicate an acute complication. The nurse should assess the client's hydration status and electrolyte levels and administer medications as prescribed.

Choice C reason: A client who has emphysema and reports dyspnea is the highest priority, because dyspnea is a sign of respiratory distress and can indicate an acute exacerbation of emphysema. The nurse should assess the client's oxygen saturation and respiratory rate and administer oxygen therapy as prescribed.

Choice D reason: A client who has esophageal cancer and reports painful swallowing is not the highest priority, because painful swallowing is a common symptom of esophageal cancer and does not indicate an acute complication. The nurse should provide the client with soft or liquid foods and administer analgesics as prescribed.

Choice A reason: This is a correct statement, because using a soft toothbrush or foam swab for oral care can help prevent trauma and irritation to the mucous membranes of the mouth, which are inflamed and ulcerated due to stomatitis. The client should brush the teeth gently and avoid using dental floss.

Choice B reason: This is an incorrect statement, because using an alcohol-based mouthwash can cause burning, drying, and further damage to the mucous membranes of the mouth, which are already compromised by stomatitis. The client should avoid using any mouthwash that contains alcohol, menthol, or other harsh ingredients.

Choice C reason: This is a correct statement, because using a straw when drinking liquids can help reduce the contact and friction of the fluids with the mouth sores, which can cause pain and discomfort. The client should drink plenty of fluids to prevent dehydration and maintain hydration.

Choice D reason: This is a correct statement, because rinsing the mouth frequently with a hydrogen peroxide solution can help cleanse and disinfect the mouth, and promote healing of the mouth sores. The client should dilute the hydrogen peroxide with water and rinse the mouth at least four times a day, or as prescribed by the provider.
