A patient has been admitted with tumor lysis syndrome (TLS). Which intervention would be incorporated into the plan of care to prevent the metabolic imbalances associated with this disorder?
Restrict foods containing potassium.
Give sodium polystyrene sulfonate for hypokalemia.
Keep urine pH below 7.0.
Restrict all oral fluids.
The Correct Answer is A
Choice A rationale
Restricting foods containing potassium helps prevent hyperkalemia, a common metabolic imbalance in tumor lysis syndrome (TLS) due to the rapid release of intracellular potassium from lysed tumor cells.
Choice B rationale
Giving sodium polystyrene sulfonate is used to treat hyperkalemia, not hypokalemia. It works by binding potassium in the gut and helping excrete it from the body, but it is not a preventive measure for metabolic imbalances in TLS.
Choice C rationale
Keeping urine pH below 7.0 is not recommended for TLS. Alkalinizing the urine to a pH above 7.0 helps prevent uric acid crystallization and renal damage, which is crucial in managing TLS.
Choice D rationale
Restricting all oral fluids is not advisable for TLS. Adequate hydration is essential to support kidney function and enhance the excretion of electrolytes and uric acid, which helps prevent and manage TLS.

Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"A"}
Explanation
Choice A rationale:
The client's low platelet count (90 x 10⁹/L) is a significant risk factor for developing Disseminated Intravascular Coagulation (DIC), a condition characterized by abnormal blood clotting and bleeding. The client's history of cancer and symptoms such as unexplained bruising and fatigue further support this risk.
Choice B rationale:
Hyperkalemia is characterized by high potassium levels, but the client's potassium level is within the normal range (4.1 mmol/L), so this is not a risk factor.
Choice C rationale:
Hyponatremia is a condition of low sodium levels in the blood. The client's sodium level is normal (137 mmol/L), so this is not a risk factor.
Choice D rationale:
Pneumonia is a lung infection, and the client's oxygen saturation is normal (98% on room air), indicating no immediate risk of pneumonia.
Choice E rationale:
Acute nephritic syndrome is a kidney disorder that can cause elevated blood urea nitrogen (BUN) and creatinine levels. The client's BUN is slightly elevated (22 mg/dL), but her creatinine level is normal (1.0 mg/dL), making this less likely.
Correct Answer is ["B","C","D"]
Explanation
Choice A rationale: Contact precautions are not necessary in this situation as the client is presenting symptoms of a possible infection related to chemotherapy-induced immunosuppression, not a contagious disease.
Choice B rationale: Placing the client in a private room is crucial to protect her from potential infections, given her compromised immune system due to chemotherapy.
Choice C rationale: Encouraging the client to increase fluid intake can help manage fever and muscle aches and keep her hydrated, which is important when dealing with symptoms of infection and fatigue.
Choice D rationale: Wearing a mask when caring for the client is necessary to protect both the client and the healthcare provider from potential infections, considering the client’s immunocompromised state.
Choice E rationale: Preparing to administer an antibiotic should be based on the healthcare provider's orders and further diagnostic results. While it might be necessary, it is not an immediate nursing action without provider confirmation.
