NCLEX-RN Exam - Topic 2 Question 6 Discussion

Actual exam question for NCLEX's NCLEX-RN exam
Question #: 6
Topic #: 2
[All NCLEX-RN Questions]

A client has renal failure. Today's lab values indicate he has an elevated serum potassium. What additional priority information does the nurse need to obtain?

Show Suggested Answer Hide Answer
Suggested Answer: B

(A) The level of consciousness is not affected by elevated potassium levels. (B) An electrocardiogram (EKG) can tell the nurse whether this client is experiencing any cardiac dysfunction or arrhythmias related to the elevated potassium level. (C) Measurement of the urine output is not a priority nursing action at this time. (D) The client's serum potassium values for the past several days may provide information about his renal function, but they are not a priority at this time.

Hmm, I thought urine output was key in renal failure cases. Surprised it's not top of the list!

I think urine output is important too, but ECG feels more urgent.

Wait, why would you need past potassium levels? Isn’t the current one enough?

Definitely need to check the ECG! High potassium can mess with the heart.

Evaluating the level of consciousness seems important, but I wonder if it’s the top priority compared to the ECG. I guess I need to think about the risks of hyperkalemia.

I recall a practice question where we had to monitor potassium levels closely. I feel like knowing the trend of the potassium values over the last few days could be crucial too.

I'm not sure if we need the urine output right now. I remember something about it being important, but isn't the ECG more urgent?

I think we should definitely check the ECG because high potassium can cause serious heart issues, right?

I've got this! The priority is definitely to evaluate the patient's cardiac status with an ECG. Elevated potassium can be life-threatening, so I need to act quickly to identify any dangerous arrhythmias or other complications.

Okay, I think the key here is to look at the trend in the patient's potassium levels over time. That will give me a better sense of how urgent the situation is and whether there are any underlying causes I need to address.

Hmm, I'm a bit unsure here. Is the urine output the most important thing to check? I feel like I need more information about the patient's overall condition and medical history to really determine the best next steps.

This seems like a straightforward question about managing a patient with elevated potassium. I'd focus on getting a full picture of the patient's condition by evaluating their level of consciousness and doing an ECG to check for any cardiac changes.

I'm going with B. Can't ignore those electrocardiographic changes - they might be the difference between life and, well, not life.

Hey, is there a 'Call the potassium police' option? Gotta love these renal failure questions, they're the 'banana peels' of the nursing exam.

I'm tempted to say A, just to see if the patient is already experiencing neurological symptoms. But B is probably the safest bet.
