Past Paper On Clinical Chemistry For Revision
Let’s be real: Anyone can stick a needle in an arm, but a true professional knows how to do it without causing a hematoma or, worse, a healthcare-associated infection. Phlebotomy isn’t just a mechanical skill; it’s a high-stakes game of chemistry, anatomy, and rigorous safety protocols.

When you’re sitting in that exam hall, you won’t just be asked “where is the vein?” You’ll be grilled on the “why” behind every wipe of an alcohol swab. To help you move past the anxiety of the unknown, we’ve sourced a comprehensive revision paper that mirrors the actual certification hurdles.

The Q&A Revision Vault: Sharpening Your Skills
To get your gears turning, let’s look at the “make or break” questions that frequently pop up in these past papers.
1. Why is the “Order of Draw” non-negotiable?
If you pull blood into a lavender tube (EDTA) before a green tube (Heparin), you’ve just cross-contaminated your samples. The additives in one tube can ruin the results of the next, leading to a misdiagnosis.
Memorizing the colors is step one, but in an exam, you need to explain why—usually, it’s to prevent additive carryover that affects electrolyte or coagulation testing.
2. What is the “Chain of Infection,” and how do we break it?
Infection control is about identifying the weak link. The chain consists of the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host.
As a phlebotomist, you are the “Mode of Transmission” if you don’t wash your hands. Your job in the exam is to identify which PPE (Personal Protective Equipment) breaks which link. For example, a mask breaks the “Portal of Entry” for airborne pathogens.
3. How do you handle a “Syncope” event during a draw?
“Syncope” is just the fancy medical word for fainting. If a patient’s eyes roll back, do you finish the draw? Absolutely not. The past paper will likely give you a scenario: Patient turns pale and starts to slump. Your immediate steps: Remove the needle, activate the safety device, and lower the patient’s head. Safety first, samples second—always.
4. What is the difference between “Standard Precautions” and “Transmission-Based Precautions”?
-
Standard Precautions: Treat every patient as if they are potentially infectious. Gloves and hand hygiene are the baseline.
-
Transmission-Based: These are the “add-ons” for known bugs like MRSA or TB. This includes gowns, N95 respirators, or eye protection.
When answering, make sure to mention that Standard Precautions apply to all blood and body fluids, regardless of the patient’s history.
How to Use This Past Paper for Real-World Success
Don’t just circle the right answers. Use this paper to build “muscle memory” for your brain:
-
The “Tube Toss”: Look at a list of tests (e.g., CBC, Glucose, PT/INR) and write down the tube color and additive for each in under 30 seconds.
-
The Safety Audit: Go through the Infection Control section and highlight every “don’t.” Don’t recap needles. Don’t palpate the vein after cleaning. Don’t use a lancet on the center of a finger.
-
The “Checklist” Method: For every procedure question, write out the steps 1 through 10. If you miss “Labeling the tube at the bedside,” you’ve failed the question. In phlebotomy, the sequence is everything.
Why Active Revision Beats Passive Reading
Reading a manual is boring; solving a problem is engaging. Using this past paper allows you to see the “traps” examiners set. They want to see if you’ll take a shortcut on safety when you’re in a rush. Prove them wrong by mastering the theory now so the practice becomes second nature.
