A nurse is caring for a client presenting with symptoms of acute coronary syndrome (ACS). Which of the following actions should the nurse prioritize?

Choice A rationale

Immediately suggesting kidney transplantation is premature and can cause undue anxiety for the client. Acute kidney injury (AKI) is a sudden decline in renal function that is often reversible with prompt and appropriate treatment. Discussing transplantation at this initial stage without a comprehensive understanding of the AKI's etiology, severity, and potential for recovery is not scientifically sound or therapeutically appropriate.

Choice B rationale

Deferring the discussion entirely to the doctor without providing any preliminary information can increase client anxiety and undermine the nurse's role as an educator and advocate. While the physician will ultimately determine the course of treatment, the nurse can provide general, accurate information about AKI and its potential for reversibility, empowering the client with knowledge without overstepping professional boundaries or offering definitive prognoses.

Choice C rationale

Acute kidney injury is frequently a reversible condition if identified and treated promptly. The kidneys possess a remarkable capacity for recovery, especially when the underlying cause (e.g., hypovolemia, nephrotoxic drugs, obstruction) is addressed. This response provides accurate, hopeful, and scientifically grounded information, emphasizing the potential for renal function restoration and alleviating immediate fears of irreversible kidney failure and the need for transplant.

Choice D rationale

While well-intentioned, this statement is overly simplistic and potentially misleading. It offers false reassurance without providing accurate information about the client's condition. The timeline for recovery from AKI can vary significantly depending on the severity and underlying cause, and stating that the client will "be fine in a few weeks" is not scientifically precise or professionally responsible. It dismisses the seriousness of the diagnosis.

Choice A rationale

Checking blood pressure is a routine vital sign assessment but does not directly address the immediate and life-threatening implications of severe hyperkalemia. While hypertension can be associated with renal disease, a potassium level of 6.8 mEq/L (normal range 3.5-5.0 mEq/L) requires urgent intervention to prevent cardiac dysrhythmias, which are a direct consequence of altered myocardial excitability.

Choice B rationale

Obtaining a serum sodium level is important for a comprehensive electrolyte assessment in ESRD, as hyponatremia or hypernatremia can also occur. However, sodium imbalances do not pose the same immediate, life-threatening cardiac risk as severe hyperkalemia. The priority is to address the critical potassium elevation to stabilize myocardial electrical activity.

Choice C rationale

Instructing the client to avoid high-potassium foods is a crucial long-term management strategy for hyperkalemia in ESRD. However, for an acute potassium level of 6.8 mEq/L, dietary modification alone will not rapidly lower the potassium to a safe range and address the immediate risk of cardiac arrest. Acute medical interventions are required.

Choice D rationale

Redrawing the potassium to verify results is the most appropriate initial action. A critically high potassium level, especially if unexpected or inconsistent with the client's current clinical status, warrants immediate confirmation. Laboratory errors can occur, and verifying the result ensures that subsequent potentially aggressive medical interventions are based on accurate data.
