2.2 Core Workflows and Decision Points

The Procedure as a Sequence of Checkpoints

Most compliance questions are really workflow questions in disguise: the stem drops you at one step and asks for the correct next action. Memorize the order, because the safe answer is usually "do the step the protocol requires here," not "skip ahead."

1. Identify the patient using two identifiers (for example, full name and date of birth), and confirm the order.
2. Hand hygiene and standard precautions before contact.
3. Explain the procedure and obtain cooperation/consent appropriate to the setting.
4. Prepare the skin and place electrodes/leads correctly.
5. Inspect equipment for electrical and mechanical hazards.
6. Acquire the tracing, watching for artifact.
7. Document and route the result per facility policy.

A question that says a tech "begins attaching electrodes" before confirming the name is testing step 1 - identity verification - not lead placement.

Verifying Identity and Order

The first checkpoint deserves its own attention because it is the most frequently tested single step. Active verification means the technician asks the patient to state their name and date of birth rather than asking "Are you Mr. " - a sick, sedated, or anxious patient may answer yes to any name. Match what the patient says against the wristband and the order. In an outpatient setting where there is no wristband, two identifiers still apply, drawn from name, date of birth, and a second approved identifier.

Confirming the order matters just as much as the person: running the right test on the wrong patient, or the wrong test on the right patient, are both sentinel-level errors. If anything fails to match - a name that differs from the order, a missing band, a patient who cannot confirm their information - the technician stops and resolves the discrepancy with the nurse before proceeding rather than guessing. This single habit prevents the most serious and preventable category of mistake in the workflow.

Infection Control and Skin Preparation

Standard precautions (the modern successor to universal precautions) require treating every patient's blood and body fluids as potentially infectious, regardless of known diagnosis. Hand hygiene before and after each patient is the single most important control. Gloves are worn when contact with fluids, broken skin, or contaminated equipment is expected, and reusable equipment (cables, blood pressure cuffs) is cleaned between patients with an approved disinfectant.

Good skin prep is both infection control and signal quality. The standard sequence:

Poor prep, loose electrodes, and tension on lead wires are the classic causes of a wandering baseline and muscle artifact.

Electrical and Patient Safety Checks

EKG machines connect electrodes directly to the patient, so a grounding fault can deliver current straight to the heart - a hazard called microshock. The technician's safety checks are practical:

• Use a grounded three-prong plug; never defeat the ground pin with an adapter.
• Inspect for frayed cords, cracked plugs, or damaged cables; remove faulty equipment from service rather than "working around" it.
• Keep liquids away from the machine and ensure the patient is not touching grounded metal.
• Stop and report any tingling, sparking, or a machine that has been dropped.

Beyond electricity, watch for falls (assist patients on and off the table, lock wheels) and protect patient privacy with drapes and gowns. The governing principle is that a safety hazard outranks convenience: the correct exam answer almost always removes the hazard before proceeding.

Documentation Integrity

The EKG is a legal record. Document factually and contemporaneously - patient identity, date and time, lead changes, artifacts, and any unusual events. Never chart subjective conclusions outside your scope (do not write "patient is having a heart attack"). To correct a paper error, draw a single line through it so it remains legible, write the correction, and add your initials and the date; do not erase, white-out, or scribble over entries. In an electronic health record (EHR), use the system's amendment function, which preserves the original entry in an audit trail.

The exam rewards answers that keep the record accurate, complete, and auditable.

Where Workflows Break Down

Most real-world errors - and most exam stems - cluster at predictable failure points. Knowing them tells you what the "safe next action" is protecting against.

A second recurring theme is consent and cooperation: even a painless test requires that the patient understands and agrees to it. When a stem describes a confused or refusing patient, the technician stops and involves the nurse or provider rather than forcing the test.
