Explanation

Cytotoxic waste is defined by its genotoxic properties, meaning it is harmful to cells and can damage or mutate genetic material (DNA).
This type of waste primarily includes materials contaminated with cytotoxic drugs, which are commonly used in cancer treatment (chemotherapy).
Due to their ability to damage DNA, these substances are often carcinogenic (cause cancer), mutagenic (cause mutations), or teratogenic (cause birth defects).

Option A: This option is too broad. While cytotoxic waste is a type of chemical waste, not all chemical waste is cytotoxic. This category also includes less hazardous substances like cleaning agents.
Option B: This is a very general and non-descriptive category. Most medical waste is non-radioactive, so this does not define the specific hazard of cytotoxic waste.
Option C: Waste with biological properties typically refers to infectious waste (e.g., contaminated with blood, bacteria, viruses) or anatomical waste. This is a separate category of biomedical waste with a different primary hazard (infection) compared to cytotoxic waste (genotoxicity).

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Definition and properties of cytotoxic waste as background academic context rather than a clinical decision trigger.
Strict adherence to cytotoxic waste management protocols is crucial for the safety of healthcare workers, patients, and the public. Exposure can occur through inhalation, skin contact, or ingestion.
Improper disposal can lead to environmental contamination and pose a significant public health risk.
What if? If a chemotherapy infusion line becomes disconnected and leaks onto the floor, a nurse must immediately cordon off the area and use a specialized cytotoxic spill kit. They cannot simply wipe it up with a paper towel, as this would spread the hazardous material and expose the cleaner to genotoxic agents.

How to Approach the Question

First, break down the term 'cytotoxic': 'cyto' refers to cell, and 'toxic' means poisonous. Therefore, it is something that is poisonous to cells.
Evaluate the options based on this understanding. The term implies a specific, high level of danger.
Option A ('chemical substances') and B ('non-radioactive') are too broad and do not capture the specific danger.
Option C ('biological properties') refers to infectious waste, which is a different hazard (pathogens) than chemical toxicity.
Option D ('genotoxic properties') means toxic to the genes/DNA within a cell. This is a precise mechanism for how a substance can be 'cytotoxic' and is the defining characteristic of drugs used in chemotherapy. This is the most accurate and specific answer.
