Autoclave suitability: Which articles listed are appropriate for sterilization by steam under pressure (autoclaving) using standard wrapped-cycle conditions?

Introduction: Autoclaving is the workhorse sterilization method in microbiology and surgery. Items that tolerate moisture and heat can be reliably sterilized by saturated steam at 121–134°C.

Given Data / Assumptions:

• Aqueous culture media are formulated for autoclaving.
• Dressing materials and surgical packs are routinely steam-sterilized.
• Reusable rubber items (e.g., surgical gloves/tubing) can be autoclaved if manufacturer allows.

Concept / Approach: Steam transfers heat efficiently and penetrates porous loads. Autoclaving denatures proteins and nucleic acids, destroying spores when time/temperature are sufficient. The common denominator is moisture and heat stability.

Step-by-Step Solution: Check each item for heat/moisture compatibility. Media → yes; dressings → yes; reusable rubber gloves → yes (per IFU). Therefore, choose the inclusive option.

Verification / Alternative check: Hospital CSSD workflows and lab SOPs list these categories for wrapped steam cycles with biologic/chemical indicators to verify sterility assurance level.

Why Other Options Are Wrong: Single selections are incomplete; “None” contradicts standard practice.

Common Pitfalls: Confusing disposable exam gloves (not autoclaved) with reusable sterile gloves supplied after autoclaving in packs; the question refers to items suitable in principle.

Final Answer: All of these.
