A nurse is caring for a client who has acute pancreatitis. After treating the client’s pain, which of the following should the nurse address as the priority intervention?

Choice A reason:

The arterial blood gas (ABG) values of pH 7.26, HCO₃ 14, and PaCO₂ 30 indicate metabolic acidosis with partial respiratory compensation. Acute kidney injury (AKI) often leads to metabolic acidosis due to the kidneys’ inability to excrete acid and reabsorb bicarbonate. The low pH indicates acidosis, the low bicarbonate (HCO₃) reflects metabolic acidosis, and the low PaCO₂ shows that the respiratory system is trying to compensate by blowing off CO₂.

Choice B reason:

The ABG values of pH 7.49, HCO₃ 30, and PaCO₂ 40 indicate metabolic alkalosis. This condition is characterized by an elevated pH and bicarbonate level. Metabolic alkalosis is not typically associated with acute kidney injury. Instead, it can result from excessive bicarbonate intake, loss of gastric acid (e.g., vomiting), or diuretic use.

Choice C reason:

The ABG values of pH 7.26, HCO₃ 24, and PaCO₂ 46 suggest respiratory acidosis. The low pH indicates acidosis, but the normal bicarbonate level and elevated PaCO₂ point to a respiratory cause rather than a metabolic one. Respiratory acidosis occurs when the lungs cannot remove enough CO₂, leading to its accumulation. This is not a typical presentation of AKI.

Choice D reason:

The ABG values of pH 7.49, HCO₃ 24, and PaCO₂ 30 indicate respiratory alkalosis. The high pH and low PaCO₂ suggest that the patient is hyperventilating, leading to excessive CO₂ loss. This condition is not commonly associated with acute kidney injury, which more frequently causes metabolic acidosis.

Choice A reason: Ask the client to blow his nose

Asking the client to blow his nose is not advisable in this situation. Blowing the nose can increase intracranial pressure and potentially worsen the condition by causing more cerebrospinal fluid (CSF) to leak or even lead to further complications. Therefore, this action should be avoided.

Choice B reason: Suction the nostril

Suctioning the nostril is also not recommended. This action can introduce infection and increase the risk of further complications. It is important to handle any potential CSF leak with care to prevent infection and other issues.

Choice C reason: Notify the physician

While notifying the physician is important, it is not the immediate first step. The nurse should first confirm whether the clear drainage is CSF. Once confirmed, notifying the physician would be the next appropriate step.

Choice D reason: Test the drainage for glucose

Testing the drainage for glucose is the correct first action. CSF contains glucose, so a positive glucose test would confirm that the drainage is indeed CSF. This is a critical step in diagnosing a CSF leak, which can occur with basal skull fractures. Confirming the presence of CSF will guide further medical interventions and management.
