A nurse is reviewing laboratory values of a client with chronic renal failure and discovers the client has a serum potassium of 6.2 mEq/L. Which of the following interventions should the nurse anticipate?

Administering sodium polystyrene sulfonate.

Initiating an IV potassium infusion.

Administering a potassium-sparing diuretic.

Encouraging the client to eat bananas.

Answer and Explanation

The Correct Answer is A

A. Administering sodium polystyrene sulfonate:
This medication removes potassium through the GI tract and is used to treat hyperkalemia.

B. Initiating an IV potassium infusion:
The client already has hyperkalemia; giving potassium would worsen it.

C. Administering a potassium-sparing diuretic:
These medications retain potassium and would further elevate potassium levels.

D. Encouraging the client to eat bananas:
Bananas are high in potassium and should be avoided in hyperkalemia.

Correct Answer is D

Explanation

A. Urinary output 25 mL/hr: This is below normal, but not an immediate airway threat.

B. Heart rate 122/min: Elevated HR is common in burns due to fluid shifts and stress.

C. Pain of 6 on a scale of 0 to 10: Pain is expected but not life-threatening.

D. Difficulty swallowing secretions: Indicates possible airway edema or inhalation injury, which can progress to airway obstruction. This is a medical emergency.

A. Maintain adequate IV hydration B. Administer broad-spectrum antibiotics C. Give IV potassium chloride D. Prepare intramuscular pain medications

Correct Answer is A

Explanation

A. Maintain adequate IV hydration: The first priority in major burns is fluid resuscitation due to massive fluid shifts and risk of hypovolemic shock.

B. Administer broad-spectrum antibiotics: Not a priority during the initial resuscitative phase. Infection control comes later unless signs of sepsis appear.

C. Give IV potassium chloride: Burn patients often experience hyperkalemia initially due to cell lysis; potassium is not given early.

D. Prepare intramuscular pain medications: IM route is avoided due to poor perfusion and risk of inadequate absorption in burn patients.
