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 B
Explanation
Choice A rationale
DIC is not controllable with lifelong heparin usage. Heparin may be used to manage DIC, but it is not a permanent solution, and the underlying cause of DIC must be addressed.
Choice B rationale
DIC is caused by abnormal coagulation involving fibrinogen. It is characterized by widespread activation of the clotting cascade, leading to both clot formation and bleeding due to consumption of clotting factors and platelets.
Choice C rationale
DIC is not a genetic disorder involving a vitamin K deficiency. It is an acquired condition resulting from severe illnesses or injuries that trigger abnormal clotting and bleeding processes.
Choice D rationale
DIC is not characterized by an elevated platelet count. Instead, it involves thrombocytopenia due to the consumption of platelets in widespread clotting, leading to a decreased platelet count.
Correct Answer is C
Explanation
Choice A rationale
Encouraging the client to drink cool water or sports drinks is appropriate for mild dehydration or heat exhaustion but not sufficient for severe heat-related illness like heat stroke, where immediate medical intervention is needed.
Choice B rationale
Administering acetaminophen 650 mg orally can help reduce fever, but it does not address the underlying issue of hyperthermia and will not provide immediate cooling needed in this emergency.
Choice C rationale
Starting an intravenous line and infusing 0.9% saline solution helps rapidly replace fluids lost through sweating and can stabilize the client's condition by rehydrating and cooling them effectively.
Choice D rationale
Encouraging rest and reassessing in 15 minutes would delay necessary medical treatment in a situation where immediate action is critical due to the severity of the client's symptoms.
