Choice A reason: Reducing the cost of cancer treatment is not the primary reason IV therapy is preferred for chemotherapy. In fact, IV administration can be expensive due to the need for specialized equipment, infusion centers, and trained personnel. While cost considerations are important in healthcare, the choice of IV therapy is based on pharmacokinetics and therapeutic effectiveness rather than financial savings. Therefore, this option is incorrect. Choice B reason: IV therapy does not eliminate side effects of chemotherapy. Chemotherapy drugs are cytotoxic and affect both cancerous and healthy rapidly dividing cells, leading to side effects such as nausea, hair loss, and immunosuppression. The route of administration does not prevent these systemic effects because once the drug enters circulation, it impacts multiple tissues. Thus, this option is scientifically inaccurate. Choice C reason: IV therapy ensures rapid distribution of chemotherapy drugs throughout the body by delivering them directly into the bloodstream. This bypasses absorption barriers such as the gastrointestinal tract and allows immediate systemic circulation. Rapid distribution is critical in chemotherapy because it ensures that the drug reaches cancer cells in different organs and tissues efficiently, maximizing therapeutic effect. Additionally, IV administration allows precise control of dosage and timing, which is essential for drugs with narrow therapeutic windows. This makes IV therapy the preferred route for chemotherapy. Choice D reason: IV therapy is not the only method available for administering chemotherapy. Chemotherapy can also be given orally, intrathecally (into the cerebrospinal fluid), or via intraperitoneal infusion depending on the type of cancer and drug formulation. However, IV therapy is most commonly used because of its effectiveness in achieving rapid systemic distribution. Therefore, this option is incorrect
