How to Answer STE404 Assessment 1: Chain of Infection, Hand Hygiene and PPE

To answer STE404 Assessment 1, explain each infection prevention and control (IPC) action as a break in a named link of the chain of infection, show correct hand hygiene timing and PPE sequencing, list every breach in the scenario with its blood-borne risk, and tie one clause of AS/NZS 5369:2023 to your findings. The Open Polytechnic marking schedule rewards completeness and clear links between cause and consequence more than long descriptions.

What the brief really asks

The assessment for STE404 Foundations of Sterilising Practice is set in a hospital sterile services department and is worth 35% of the course. It is built from two scenarios. In the first, instruments are cleaned by hand because the washer-disinfector is unavailable, and staff make several mistakes with gloves and eye protection. In the second, you observe unsafe PPE practices in the decontamination area and must reflect on how you would respond. You can read the full wording on the STE404 Assessment 1 question page.

Underneath the scenarios, the marker is testing three skills: describing correct practice accurately, spotting what is wrong, and explaining why it matters in terms of the chain of infection (reservoir, portal of exit, mode of transmission, portal of entry and susceptible host). Other Open Polytechnic briefs are listed in the Open Polytechnic assessment hub.

Word and mark split

Notice that the reflection and response questions carry 40 of the 100 marks, so they deserve more than a closing paragraph.

Step-by-step plan

1. Draw the chain of infection on rough paper and label where each scenario error sits.
2. For hand hygiene, state what is done before handling contaminated items, after handling them and after glove removal, then give the reason for each timing.
3. For PPE, justify the items by the exposure (splash, aerosol, contact) and then give the donning and doffing order, ending with hand hygiene.
4. List every breach in the scenario, one line each, and link it to blood-borne exposure and to spread within the department.
5. Choose one clause of AS/NZS 5369:2023 that fits your breaches and explain the link in your own words. The standard’s official listing is on the Standards New Zealand page for AS/NZS 5369:2023.
6. For Task 2, write the unsafe practices, your spoken response to each, and a genuine reflection in that order.
7. Check word counts, citations and reference formatting last.

How to reach the higher bands

Top-band answers are complete, accurate and connected. For hand hygiene, they include the moment-based reasoning behind timing. For PPE, they treat selection and sequence as two separate points, since the marking schedule asks for both. For the breaches, they find every error, including the less obvious ones such as removing gloves and then reusing the same pair, or failing to clean hands between glove changes. For the standard, they name the clause and show how it supports the specific breaches rather than describing the standard in general terms.

Linking each breach to the chain

A reliable way to earn the breach marks is to use a three-part sentence for each error: what happened, which link in the chain it affects, and what harm follows. For example, working without eye protection while scrubbing forceps exposes the mucous membranes of the eyes, which are a portal of entry for blood-borne viruses, and the splash can also contaminate gloves, face and work surfaces. Removing gloves for a phone call and then re-gloving shows the same pattern: bare hands touch a contaminated environment, the phone becomes a fomite, and reused gloves carry organisms back onto instruments and surfaces that were previously clean.

Keep spread within the department in view. Sterile services is organised into dirty-to-clean zones precisely so that organisms stay where they can be controlled. Every breach that carries contamination out of the decontamination area weakens that design, and a short sentence saying so shows the marker that you understand the purpose of the workflow, not only the rule.

Writing the Task 2 reflection well

Task 2 asks what you would do in the moment, which is a communication question as much as a technical one. Strong answers use specific, calm wording, such as offering a clean face shield, asking a colleague to retie a gown, or suggesting that a phone be stored in a locker. They also say when you would escalate to a supervisor and how you would document the event. For the personal experience question, choose a real moment of uncertainty, describe it in two or three sentences, and spend most of the word count on what you did and what you will do differently. A reflection that ends with a concrete habit, such as checking the donning order before each shift, reads as genuine learning and is easier to mark highly.

Use the first person for reflection, but keep the rest of the answer in formal, third-person style. Avoid naming colleagues or your workplace, and describe events in general terms so that no individual can be identified.

Mark-maximising checklist

• Every breach in the scenario is identified, with no omissions.
• Each breach is linked to a link in the chain of infection.
• Blood-borne exposure routes (mucous membranes, non-intact skin, sharps) are named.
• Hand hygiene is explained for before, after and on glove removal.
• Donning and doffing are described as an ordered sequence.
• One AS/NZS 5369:2023 clause is cited by number and linked to the breaches.
• Task 2 responses are professional, specific and show speaking up.
• The reflection draws on a real experience and states what you will do differently.
• Sources are current and in the referencing style your provider requires.

Common mistakes

• Describing PPE generally without saying why each item suits manual cleaning.
• Giving donning order but not doffing order, or forgetting the hand hygiene step at the end.
• Listing only the obvious breach (no eye protection) and missing the glove reuse and phone use.
• Naming the standard without choosing or linking a specific clause.
• Writing Task 2 as a lecture rather than describing what you would actually say to a colleague.
• Using an invented or vague reflection with no learning outcome.
• Ignoring the word guidelines and running over on Task 1.

Presenting it as a short report

FAQs

What is the chain of infection?

It is the sequence of links by which an infection spreads: the infectious agent, the reservoir, the portal of exit, the mode of transmission, the portal of entry and the susceptible host. Breaking any link stops transmission.

When should hands be cleaned in sterile services?

Before handling contaminated items to protect the work area, after handling them, and immediately after removing gloves. Soap and water is used for visibly soiled hands, and an alcohol-based product for hands that are not visibly soiled.

Why do the donning and doffing sequences matter?

The outside of PPE becomes contaminated during cleaning. A planned order prevents gaps when putting it on and prevents contaminated surfaces touching skin, hair or clothing when taking it off.

Do I need to cite AS/NZS 5369:2023 by clause number?

The brief asks for one relevant section or clause, so yes, name it clearly and explain how it supports your analysis of the breaches. Use the copy supplied through your course.

Is APA 7 required?

The brief does not state a referencing style, so check the official assessment instructions on iQualify. APA 7 is a common and safe choice if nothing is specified.

Can I write the reflection if I have limited work experience?

Yes. Use a genuine placement, training or simulated experience where you felt unsure about PPE, and be specific about what you did and learned.
