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 A

Explanation

A. Hyperkalemia: During the emergent phase, massive cell injury causes potassium to leak into the extracellular space, raising serum K+ levels.

B. Hypokalemia: More common later in the fluid resuscitation or diuretic phase.

C. Hypernatremia: Sodium is often lost into burned tissues or with fluid shifts; hyponatremia may be seen early.

D. Hypocalcemia: While possible, especially if blood products are given, hyperkalemia is more prominent early.

A. Assessing the client's support system B. Assessing and removing any rings or jewelry from affected limb C. Assessing the client's circulation distal to the burn site D. Assessing the client's urine output E. Assessing the client's respiratory function

Correct Answer is ["B","C"]

Explanation

A. Assessing the client's support system: Important in overall care, but not a priority in the acute phase.

B. Assessing and removing any rings or jewelry from affected limb: Jewelry can cause constriction due to swelling; removing it prevents further vascular compromise.

C. Assessing the client's circulation distal to the burn site: Circumferential burns can compromise perfusion due to edema or eschar formation. Checking pulses, cap refill, and sensation is essential.

D. Assessing the client's urine output: Important in systemic burns, but not directly related to a localized forearm burn.

E. Assessing the client's respiratory function: Critical in burns involving the face or inhalation injury, but not the forearm.
