Which client should the nurse prioritize seeing first based on potassium levels?

• A. A 52-year-old admitted with chronic kidney injury with a serum potassium level of 7.1 mEq/L.
• B. A 35-year-old who is sleeping after a tonic-clonic seizure lasting 1 minute.
• C. A 63-year-old who is post-operative right knee replacement and is requesting bedpan.
• D. A 22-year-old admitted with sickle cell crisis complaining of abdominal pain.

Answer: (A)

The priority for the nurse in this scenario is the patient with chronic kidney injury presenting with a serum potassium level of 7.1 mEq/L. This level is critically high and falls into the category of hyperkalemia, which can have severe and life-threatening complications, such as cardiac arrhythmias and potential cardiac arrest. High potassium levels can impair the normal electrical activity of the heart, leading to conditions like ventricular fibrillation.

In contrast, while the other patients may require attention, their situations are not immediately life-threatening due to lab values. The patient post-operative from a knee replacement is likely stable, and the request for a bedpan does not indicate an emergency. The patient who has just experienced a tonic-clonic seizure and is sleeping warrants monitoring and possibly further evaluation, but they are not in acute danger from their current state. The individual with sickle cell crisis also requires care, especially with abdominal pain, but does not present with the same immediate risk associated with elevated potassium.

Therefore, prioritizing the patient with a high potassium level is crucial due to the high risk of serious complications and the need for immediate intervention, such as administering medications to lower potassium, potentially starting cardiac monitoring, and assessing for any acute cardiac changes.
