A patient has a serum phosphate level of 4.7 mg/dL. Which treatments should the nurse expect to be prescribed for this patient? Select all that apply.
Normal saline.
Potassium phosphate.
Additional milk intake.
Increased Vitamin D intake.
Correct Answer : B,D,E
Choice A rationale:
Normal saline is not indicated for the treatment of high serum phosphate levels. It is a solution used for fluid resuscitation or hydration but does not have any direct effect on phosphate levels.
Choice B rationale:
Potassium phosphate is a suitable treatment for a patient with a low serum phosphate level (hypophosphatemia). In this case, the patient has a high serum phosphate level, and administering more phosphate would exacerbate the condition.
Choice C rationale:
Additional milk intake is not a suitable treatment for high serum phosphate levels. Milk contains phosphate, which would further elevate the phosphate level.
Choice D rationale:
Increased Vitamin D intake is a valid treatment for high serum phosphate levels (hyperphosphatemia). Vitamin D helps regulate phosphate levels by promoting its excretion.
Choice E rationale:
Calcium-containing antacids are used to bind phosphate in the gastrointestinal tract and reduce its absorption, thus lowering serum phosphate levels. This makes it a suitable treatment for hyperphosphatemia.

Correct Answer is D
Explanation
The correct answer is choice D: Reduction of T-wave amplitude.
Choice A rationale:
The amplitude of the QRS complex is not directly affected by changes in serum potassium levels. It represents ventricular depolarization, and its restoration would not be an expected outcome of polystyrene sulfonate treatment
Choice B rationale:
Shortening of the P-wave duration is not an expected change with polystyrene sulfonate treatment. The P-wave represents atrial depolarization, which is not significantly impacted by the administration of this medication
Choice C rationale:
Widening of the QRS complex is associated with high serum potassium levels. The goal of polystyrene sulfonate treatment is to lower potassium levels and, thus, return the QRS complex to its normal width
Choice D rationale:
Polystyrene sulfonate aims to reduce serum potassium levels. When effective, this should result in a reduction of T-wave amplitude, which is a common ECG change seen with hyperkalemia
In conclusion, choice D is the correct answer, as a reduction in T-wave amplitude would be the expected change on the client's ECG if polystyrene sulfonate effectively lowers their serum potassium level.
Correct Answer is A
Explanation
The correct answer is choice A. Client has an NG tube to gastric suction.
Choice A rationale:
Having an NG tube to gastric suction can lead to hypokalemia because the suctioning process removes potassium from the stomach contents, leading to a decrease in serum potassium levels.
Choice B rationale:
While a history of alcohol abuse disorder can lead to various electrolyte imbalances, it is not the most direct cause of hypokalemia compared to gastric suction.
Choice C rationale:
Drinking 3.5 to 4 liters of water each day can lead to dilutional hyponatremia but is less likely to cause hypokalemia directly.
Choice D rationale:
Spironolactone is a potassium-sparing diuretic, which means it helps retain potassium in the body. Therefore, it is not a causative factor for hypokalemia.
