a-IPC common mistakes
a-IPC · Understand the traps and how to avoid them.
Selecting the most aggressive or broadest precaution (e.g., contact precautions plus dedicated equipment) for every scenario instead of matching the precaution tier to the actual transmission route described.
Candidates overgeneralize from memorable outbreak scenarios and assume 'more precaution equals safer answer,' ignoring that the question is testing tier selection based on route of transmission.
What to do instead
Before answering, explicitly name the transmission route in the stem (contact, droplet, airborne) and choose only the precautions that route requires; treat extra precautions as wrong unless the stem supplies a reason.
Confusing when hand hygiene with soap and water is required versus when alcohol-based hand rub is acceptable, and picking alcohol rub for spore-forming organisms or visibly soiled hands.
Candidates memorize 'alcohol rub is preferred' as a blanket rule and fail to recall the specific exceptions tied to C. difficile, norovirus, and visible contamination.
What to do instead
Build a two-column recall list (alcohol rub acceptable vs. soap and water required) and rehearse the exceptions until the trigger words in a stem immediately map to the correct agent.
Mixing up the sequence and timing rules for donning and doffing personal protective equipment, especially removing gloves before the gown and performing hand hygiene at the wrong step.
The steps are procedural and easy to 'feel' correct in the wrong order; candidates rely on intuition rather than a rehearsed sequence.
What to do instead
Practice the doffing order aloud as a fixed chain (gloves, hand hygiene, gown, hand hygiene, then eye protection and mask/respirator, hand hygiene) and apply it to every PPE item.
Choosing a surgical mask when the scenario requires a fit-tested N95 respirator (or vice versa) without checking whether the stem describes an airborne pathogen or an aerosol-generating procedure.
Candidates treat masks and respirators as interchangeable and do not anchor the choice to the pathogen's transmission category or the procedure being performed.
What to do instead
Tie the answer to two stem cues: airborne transmission or aerosol-generating procedure means respirator; droplet transmission means surgical mask; state the cue before selecting.
Applying standard precautions only to patients with a known diagnosis rather than to all patients regardless of suspected or confirmed infection status.
Candidates reason from a clinical 'known case' mindset and overlook that standard precautions are universal and diagnosis-independent.
What to do instead
When a question mentions standard precautions, default to 'all patients, all body fluids, at all times' and reject any option that conditions standard precautions on a diagnosis.
Skipping or misordering the cleaning-then-disinfection logic for reusable equipment and environmental surfaces, treating disinfection as a substitute for cleaning.
Candidates collapse cleaning and disinfection into one step and forget that organic material reduces disinfectant efficacy.
What to do instead
Memorize the rule 'clean first, then disinfect' and select answers that include a mechanical cleaning step before any chemical disinfection.
Answering scope-of-practice questions by choosing the action that best helps the patient rather than the action the associate-level role is permitted to perform independently.
Candidates default to patient-advocacy reasoning and ignore the delegation and supervision boundaries that the item is actually testing.
What to do instead
For scope items, first identify the role named in the stem, then eliminate any option that requires a higher license or lacks required supervision, even if clinically helpful.
Reporting an exposure or needlestick incorrectly, such as delaying the report until the end of shift or washing a puncture wound with harsh agents instead of soap and water.
Candidates focus on the injury itself and underestimate the time-sensitive reporting and post-exposure evaluation pathway.
What to do instead
Memorize the post-exposure sequence: wash with soap and water, report immediately, seek source evaluation and post-exposure prophylaxis guidance per protocol.
Confusing sterilization with high-level disinfection and selecting the wrong reprocessing level for semicritical versus critical items.
Candidates use the terms loosely and do not link the item's body-contact category to the required reprocessing level.
What to do instead
Anchor to the Spaulding classification: critical items (sterile body sites) require sterilization; semicritical items (mucous membranes) require high-level disinfection; noncritical items require low-level disinfection.
Failing to recognize when an immediate infection-control escalation (e.g., placing a patient in appropriate precautions, notifying the infection prevention team) is the correct first action rather than continuing routine care.
Candidates treat notification and isolation as administrative afterthoughts and prioritize the clinical task in front of them.
What to do instead
When a stem describes a suspected transmissible infection, choose the option that initiates the correct precaution and notification first, then resumes clinical care.
