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 A
Explanation
Sodium 155 mEq/L. Choice A rationale:
A urine specific gravity of 1.035 indicates concentrated urine and is consistent with fluid volume deficit. However, it is not the most specific finding for this condition.
Choice B rationale:
A BUN (blood urea nitrogen) level of 19 mg/dL can be a normal value. It is within the reference range (usually around 7-20 mg/dL) and does not provide specific information about fluid volume deficit.
Choice C rationale:
A hematocrit of 44.9% can also be within the normal range for some individuals, and while it can be elevated in cases of fluid volume deficit, it is not as sensitive as other parameters for detecting this condition.
Choice D rationale:
This is the correct answer because a sodium level of 155 mEq/L is elevated and indicates hypernatremia, which is associated with fluid volume deficit. Hypernatremia occurs when there is a relative lack of water in relation to the sodium concentration in the blood, and it can lead to dehydration
Correct Answer is D
Explanation
Choice A rationale:
Hypokalemia is not a direct adverse effect of dextrose 10% in water infusion. This solution does not contain potassium, and unless the patient already has low potassium levels or other contributing factors, it would not cause hypokalemia.
Choice B rationale:
Hypercalcemia is unrelated to dextrose 10% in water infusion. The solution does not contain calcium, and it would not lead to an increase in serum calcium levels.
Choice C rationale:
Hypovolemia, or low blood volume, is not typically associated with dextrose 10% in water infusion. However, if administered rapidly in large amounts, it could potentially cause fluid overload leading to hypervolemia.
Choice D rationale:
Hyperglycemia is a possible adverse effect of dextrose 10% in water infusion. The solution contains a high concentration of glucose, which can raise blood sugar levels if the body cannot adequately utilize or regulate the glucose. Regular monitoring of blood glucose levels is essential during such an infusion, especially in patients with diabetes or impaired glucose tolerance.
