A client has a nasogastric (NG) tube placed during abdominal surgery. During postoperative convalescence, which arterial blood gas values are consistent with metabolic alkalosis?
pH 7.49, PCO₂ 45 mm Hg, HCO₃ 32 mEq/L (32 mmol/L), PO₂ 90 mm Hg.
pH 7.30, PCO₂ 20 mm Hg, HCO₃ 22 mEq/L (22 mmol/L), PO₂ 85 mm Hg.
pH 7.46, PCO₂ 55 mm Hg, HCO₃ 36 mEq/L (36 mmol/L), PO₂ 95 mm Hg.
pH 7.29, PCO₂ 35 mm Hg, HCO₃ 25 mEq/L (25 mmol/L), PO₂ 99 mm Hg.
The Correct Answer is A
Choice A rationale
pH 7.49, PCO₂ 45 mm Hg, HCO₃ 32 mEq/L (32 mmol/L), PO₂ 90 mm Hg indicates metabolic alkalosis. The elevated pH and HCO₃ levels are consistent with this condition.
Choice B rationale
pH 7.30, PCO₂ 20 mm Hg, HCO₃ 22 mEq/L (22 mmol/L), PO₂ 85 mm Hg indicates metabolic acidosis with respiratory compensation, not metabolic alkalosis.
Choice C rationale
pH 7.46, PCO₂ 55 mm Hg, HCO₃ 36 mEq/L (36 mmol/L), PO₂ 95 mm Hg indicates metabolic alkalosis with respiratory compensation. However, the pH is slightly lower than in Choice A, making Choice A more indicative of metabolic alkalosis.
Choice D rationale
pH 7.29, PCO₂ 35 mm Hg, HCO₃ 25 mEq/L (25 mmol/L), PO₂ 99 mm Hg indicates metabolic acidosis, not metabolic alkalosis.

Correct Answer is C
Explanation
Choice A rationale
Advising the client that it is too late to receive an influenza vaccination once symptoms occur is correct, but it does not address the client’s question about oseltamivir.
Choice B rationale
Explaining that antibiotics are not useful in treating viral infections is correct, but it does not address the client’s question about oseltamivir.
Choice C rationale
Referring the client to the healthcare provider to obtain a medication prescription is the most appropriate response. Oseltamivir is an antiviral medication that can be effective if started within 48 hours of symptom onset.
Choice D rationale
Instructing the client that over-the-counter medications are sufficient to manage influenza symptoms is not appropriate, as oseltamivir can help reduce the severity and duration of the illness if taken early.
Correct Answer is C
Explanation
Choice A rationale
Restricting fluids is not a primary limitation for clients with Crohn’s disease. Adequate hydration is important for overall health and managing symptoms.
Choice B rationale
Limiting foods high in calcium and iron is not typically recommended for Crohn’s disease. These nutrients are important for maintaining bone health and preventing anemia, which can be concerns for individuals with Crohn’s disease.
Choice C rationale
An elimination diet can help identify trigger foods that may exacerbate symptoms of Crohn’s disease. This approach involves removing certain foods from the diet and gradually reintroducing them to determine which foods cause symptoms.
Choice D rationale
Avoiding gluten is not necessary for all individuals with Crohn’s disease. While some may benefit from a gluten-free diet, it is not a universal recommendation for managing the condition.
