A nurse is reviewing a client's laboratory values and discovers the client has a serum potassium of 6.2 mEq/L. Which of the following interventions should the nurse anticipate?
Administering a potassium-sparing diuretic.
Administering sodium polystyrene sulfonate.
Initiating an IV potassium infusion.
Encouraging the client to eat bananas.
The Correct Answer is B
The correct answer is choice B) Administering sodium polystyrene sulfonate.
Choice A rationale:
Administering a potassium-sparing diuretic is not appropriate for a client with hyperkalemia (high potassium levels). Potassium-sparing diuretics would further increase potassium levels, worsening the condition.
Choice B rationale:
Sodium polystyrene sulfonate is used to treat hyperkalemia. It works by exchanging sodium ions for potassium ions in the intestines, which helps to lower serum potassium levels by excreting it through the stool.
Choice C rationale:
Initiating an IV potassium infusion would be contraindicated in this situation as it would increase the already elevated potassium levels, potentially leading to dangerous cardiac complications.
Choice D rationale:
Encouraging the client to eat bananas is not advisable because bananas are high in potassium, which would exacerbate hyperkalemia.

Correct Answer is B
Explanation
Cerebral bleeding. Choice A rationale:
Stress fractures are not directly related to hypernatremia. Hypernatremia is an electrolyte imbalance, and its main effects are related to cellular dehydration and neurological symptoms rather than bone fractures.
Choice B rationale:
This is the correct answer because hypernatremia can lead to severe dehydration and cause neurological complications, including cerebral bleeding. The brain cells can shrink due to water loss, causing blood vessels to rupture, leading to bleeding in the brain.
Choice C rationale:
Atrial dysrhythmias are not directly associated with hypernatremia. Hypernatremia primarily affects the central nervous system and can lead to neurological symptoms rather than cardiac dysrhythmias.
Choice D rationale:
Pulmonary edema is not a likely consequence of hypernatremia. Pulmonary edema is associated with fluid volume excess, not fluid volume deficit, which is characteristic of hypernatremia.
Correct Answer is ["B","C","E"]
Explanation
Choice A rationale:
Dysrhythmias are not a direct consequence of diabetic ketoacidosis (DKA) or the acid-base imbalance indicated by the patient's pH of 7.2 and bicarbonate level of 20 mEq/L. DKA primarily affects the respiratory system, leading to Kussmaul respirations, not dysrhythmias.
Choice B rationale:
Kussmaul respirations are an expected finding in a patient with diabetic ketoacidosis (DKA) and metabolic acidosis. These deep, rapid breaths are the body's attempt to compensate for the acidosis by eliminating excess CO2.
Choice C rationale:
Weakness is a common symptom of DKA. The hyperglycemia and acidosis result in intracellular dehydration and impaired cellular function, leading to weakness and fatigue.
Choice D rationale:
Cold, clammy skin is not typically associated with DKA. Instead, patients with DKA may have warm, dry skin due to dehydration and impaired thermoregulation.
Choice E rationale:
Tachycardia is an expected finding in a patient with DKA. The metabolic acidosis and dehydration lead to an increase in heart rate as the body attempts to maintain perfusion.
