A nurse is reinforcing teaching with a client who is scheduled for an intravenous pyelogram. Which of the following statements by the client indicates an understanding of the teaching?

Choice A reason: Eating 2 hours before an IVP is incorrect; fasting is required 4-8 hours prior to ensure clear imaging. Scientifically, food can obscure contrast in the urinary tract, reducing diagnostic accuracy, showing misunderstanding of prep needs.Choice B reason: Limiting fluids post-IVP is wrong; hydration flushes dye, preventing kidney strain. Scientifically, adequate fluid intake post-contrast is standard to reduce nephrotoxicity risk, indicating the client misgrasps aftercare critical to renal safety.Choice C reason: Not needing consent is false; IVP involves contrast risks (e.g., allergy), requiring informed consent. Scientifically, legal and medical standards mandate consent for invasive imaging, reflecting a lack of understanding about procedural protocols.Choice D reason: A warming sensation from dye injection is accurate, as contrast dilates vessels briefly. Scientifically, this common reaction shows the client understands the procedure’s sensory effects, aligning with expected physiological responses per IVP education.
