Which of the following clients would not be a candidate for a peripheral IV?

A. A client experiencing nausea and vomiting needing replacement electrolytes is incorrect because a peripheral IV is appropriate for short-term fluid and electrolyte replacement in clients who require immediate hydration or correction of mild imbalances. Peripheral access is safe and effective for these purposes. B. A client experiencing dehydration receiving short-term replacement fluids is incorrect because peripheral IVs are suitable for short-term fluid therapy, including rehydration for mild to moderate dehydration. The veins can typically accommodate the necessary rate and volume for temporary treatment. C. A client needing chemo infusion for 6–8 weeks is correct because peripheral IVs are not ideal for long-term or vesicant medication administration, such as chemotherapy. Peripheral veins are prone to irritation, phlebitis, and infiltration over extended periods. Central venous access (e.g., PICC line, port, or tunneled catheter) is preferred for long-term chemotherapy to ensure safe delivery, protect veins, and reduce complications. D. A client receiving fluids postoperatively is incorrect because peripheral IVs are commonly used postoperatively for hydration, medication administration, and short-term fluid replacement. Peripheral access is generally sufficient for typical postoperative needs.
