The nurse is reviewing laboratory results for a client admitted for renal failure and notes the following: Sodium 144 mEq/L and Potassium 6.6 mEq/L. Which of the following should be the priority intervention?

Request a CT scan of the head.

Assess for Chvostek’s sign.

Obtain a chest X-ray.

Obtain a 12-lead ECG.

Answer and Explanation

The Correct Answer is D

A. A CT scan of the head is not indicated based on the laboratory findings provided. The priority intervention is related to the elevated potassium level.
B. Chvostek’s sign is associated with hypocalcemia (low calcium levels), not hyperkalemia (high potassium levels).
C. A chest X-ray is not the priority intervention for elevated potassium. The primary concern is the potential for cardiac arrhythmias related to the high potassium level.
D. Hyperkalemia (potassium 6.6 mEq/L) can lead to cardiac arrhythmias. The nurse should obtain a 12-lead ECG to assess for any changes in the heart's electrical activity, which could indicate serious complications like arrhythmias or cardiac arrest.

Correct Answer is ["B","D","E"]

Explanation

A. Intact motor function is not a sign of compartment syndrome. Motor deficits, rather than intact function, would raise concern for this condition.
B. A capillary refill time of 5 seconds is prolonged and indicates impaired circulation, which is a sign of compartment syndrome.
C. A bounding pulse is not consistent with compartment syndrome. Pulses may initially remain normal but can diminish as the condition progresses.
D. Pallor to the lower extremity suggests compromised blood flow, which is a hallmark of compartment syndrome.
E. Numbness and tingling (paresthesia) indicate nerve compression, a common symptom of compartment syndrome.

A. "I should drink 1 to 2 glasses of fluid a day to help flush the bacteria out." B. "My medication may discolor my urine, this should resolve once the medication is stopped." C. "I should stop taking my medications once symptoms have resolved." D. "These medications are given to treat fungal infections."

Correct Answer is B

Explanation

A. The patient should increase fluid intake to 6 to 8 glasses of water daily, not 1 to 2 glasses, to help flush bacteria out of the urinary tract.
B. Phenazopyridine (Pyridium) can cause orange or red discoloration of urine, which is a harmless and temporary side effect that resolves after the medication is stopped. This indicates the patient understands the teaching.
C. Stopping medications prematurely can lead to incomplete treatment of the infection and potential antibiotic resistance. Patients should complete the full course of prescribed antibiotics.
D. Sulfamethoxazole-trimethoprim (Bactrim) is an antibacterial, and phenazopyridine is a urinary analgesic; neither medication is used to treat fungal infections.
