The Fastest Way to Lose a DI Station
You’re halfway through an OSCE circuit.
A nurse pops in and asks:
“Can we give this medication through the NG tube? The patient’s already on feeds.”
You feel your brain heat up. You think you saw something about crushing that drug once. You grab for an answer.
You guess.
In the real world, guessing might cause harm. In the PEBCs, guessing quietly kills the station.
The people who leak marks on Drug Information (DI) questions all make the same mistake:
They answer the question they think they heard, instead of clarifying the question that’s actually being asked.
The good news? There’s one habit that flips this from a weakness into a strength.
30 Second Summary
This article is for you if Drug Information (DI) questions make you want to guess fast.
You’ll learn one habit: ask at least one clarifying question before you give an answer.
It gives you a 3-step script to use in DI questions so you sound safe and professional, not rushed.
If you worry about “saying the wrong thing” in DI, this article teaches you how to slow down, protect the patient, and still score well.
The One-Question Rule for Every DI Scenario
By the end of this post, you’ll learn a simple, repeatable rule you can use in:
Written DI questions
OSCE DI stations
Drug info requests in practice
So that you can:
Avoid unsafe, premature answers
Show examiners you think like a real, responsible pharmacist
Turn DI stations from “panic and guess” into “follow the algorithm”
The rule is this:
Before you answer any DI question, ask at least one clarifying question that safeguards the patient.
Sounds almost too simple. But it changes everything.
What Examiners Actually Want to See
Remember:
You’re reminded to “ALWAYS ask for more information” before answering.
You’re encouraged to separate what’s certain (known facts) from what’s uncertain (assumptions, missing details).
You’re shown different types of DI questions: PK, PD, availability, on-label vs off-label, etc.
PEBC isn’t trying to reward the fastest talker.They’re trying to reward the pharmacist who:
Slows down just enough to not harm the patient
Recognizes when a question is dangerously underspecified
Chooses a safe process over a flashy answer
In other words, the candidate who says:
“Before I give you a definite answer, I just need to clarify a few details.”
…almost always scores better than the candidate who blurts out the “right” drug but ignores the missing context.
The 3-Step “Clarify First” Framework for DI Questions
Step 1 – Freeze the Answer, Clarify the Question Your first move in any DI scenario is not to show how smart you are. It’s to make sure you’ve understood the question in a way that keeps the patient safe.
Use one of these stock phrases:
“Before I answer, can I ask you a couple of quick questions about the patient?”
“I can definitely look into that—can you tell me a bit more about their situation first?”
“To make sure I’m giving you the safest answer, I just want to clarify a few details.”
Then target 3 key areas:
Who is the patient?
Age, pregnancy/breastfeeding, renal/hepatic function, key comorbidities.
Example: “Is this for an adult or a child? Any history of kidney or liver problems?”
What exactly is being asked?
Is it about safety, efficacy, compatibility, dose, route, or administration?
Example: “Just to confirm, are you asking if this is safe in pregnancy, or more about the best dose?”
What are they already doing or planning?
Current meds, OTCs, herbals, existing plan.
Example: “What are they taking right now (including non-prescription products)?”
This alone will set you apart. Most candidates jump straight to answering.You’ll be the one who structures the problem first.
Step 2 – Separate Facts from Assumptions Once you’ve clarified, do a quick mental split.
Certain facts (you now know these for sure)
Uncertain details (what you still don’t know and can’t safely guess)
Say it out loud in the station. Examiners love hearing your thinking.
Example script:
“So, to summarize: we’re talking about a 72-year-old woman with AFib on warfarin, currently starting TMP/SMX for a UTI. You’re wondering if that’s safe together. I know her age and that she’s on warfarin, but I don’t have her current INR or renal function yet, so I’ll keep that in mind as I look this up.”
Why this works:
You show you’re consciously aware of what’s missing.
You signal that your answer will be conditional (“based on what we know, here’s what I recommend plus what to monitor”).
This is where your notes on types of DI questions help:
If it’s a PK question → Think dosing, clearance, organ function.
If it’s PD / interaction → Think additive effects, toxicity, INR, QT, CNS depression, etc.
If it’s availability / formulation → Think strengths, dosage forms, can it be crushed/compounded.
If it’s on/off-label use → Think evidence level and guideline alignment.
You don’t need to say those labels out loud, but use them internally to organize your thinking.
Step 3 – Answer in Layers: Safety First, Details Second When you finally answer, don’t just drop a one-liner.
Use this 3-layer structure:
Safety headline (what they need to know right now)
Rationale (the “because”)
Next steps & monitoring (what to do / watch)
Example 1 – Interaction question
“Given what we know, I’d be concerned about a significant interaction between warfarin and TMP/SMX, because TMP/SMX can raise INR and increase bleeding risk. I’d recommend either choosing an alternative antibiotic that doesn’t interact as strongly, or, if this is the best option, using it with close INR monitoring and counseling the patient on bleeding signs.”
Example 2 – Administration/compatibility question
“With this medication, I’d avoid crushing the controlled-release tablets for NG tube administration because that can alter absorption and increase side effects. I’d suggest we switch to an immediate-release version or a liquid formulation if available, and adjust the dosing schedule accordingly.”
What you’ve just done:
Protected the patient (no reckless “yeah it’s fine, go ahead”).
Shown you understand why something is or isn’t safe.
Given a plan the examiner can check off against their marking scheme: identify risk, offer alternative, suggest monitoring.
Put It All Together: The DI Mini-Script
Here’s the whole thing as a script you can practice:
Clarify
“Before I answer, can I ask a couple of quick questions about the patient and the situation?”
Summarize & separate
“So this is a [age]-year-old with [conditions], on [key meds], and you’re asking about [specific issue]. I know [certain facts], but we don’t have [uncertain details], so I’ll keep that in mind.”
Answer in layers
Safety first: “Based on this, I’d be concerned about…” / “This should be safe if…”
Rationale: “Because...” (mechanism, interaction, guideline, etc.)
Next steps: “I’d recommend we do [alternative / adjustment] and monitor [parameter/symptom].”
Use this for every DI question and you’ll start to see patterns instead of randomness.
If this one habit already makes DI questions feel more manageable, imagine having:
A similar framework for ethics, jurisprudence, communication, adherence, documentation, workflow, and storage
With PEBC-style examples, “wrong but tempting vs right but boring” answers, and ready-made scripts
That’s exactly what I’m building for members inside Knowbly.
If you want to:
Stop bleeding marks on “soft” stations
And start using simple, repeatable patterns like this one across every non-therapeutic domain
Then this is your sign to dive into the rest of the series and start stacking these micro-advantages now.
