October 2026 - Identifying Inconsistencies Study Guide for nursing students in
Some passages deliberately contain a claim that contradicts another statement, or a conclusion the evidence does not reach. You are being asked to notice the mismatch, not to resolve it, and the mismatch is nearly always between two places in the text rather than between the text and the world.
The four kinds of inconsistency
Almost every question of this type is one of these. Knowing the categories tells you what to look for.
- Direct contradiction — two statements that cannot both be true, usually paragraphs apart.
- Conclusion beyond the evidence — the passage's own data does not reach the claim it makes.
- Shifting definition — a term used one way early and a different way later.
- Figures that do not reconcile — percentages that exceed a hundred, parts that do not sum to the stated total, a figure quoted twice with different values.
What is not an inconsistency
Two things regularly mistaken for contradictions: a change of mind that the author signals, and a statement you happen to disagree with. If the passage says "we initially believed X; the later data showed Y", that is a narrative of revision, not an inconsistency. And a claim that conflicts with something you know from elsewhere is a claim you might challenge, not an internal inconsistency.
The question is always about the text with itself. Keep your own knowledge out of it.
Spotting the mismatch
Worked example
Passage: "The audit found that no ward exceeded its agreed staffing ratio at any point in the quarter. Managers attributed the improved sickness figures to this stability. It should be noted that the medical ward operated three shifts a week below its agreed ratio throughout October."
- Sentence one: no ward exceeded its ratio at any point. Note what "exceeded" means here — the audit is about breaching a limit.
- Sentence three: one ward operated below its ratio for a month.
- Ask whether both can be true. They can, if "exceeded" means "went over the maximum" and "below" means understaffed — but then sentence two does not follow, because the quarter was not stable for that ward.
- Name the mismatch precisely: the conclusion of stability is inconsistent with the October shortfall, whatever the first sentence measures.
The inconsistency is between the claim of stability and the reported month of understaffing. The word "exceeded" is doing quiet work in the first sentence, which is what allows the passage to look self-consistent at a glance.
Watch qualifying words at the start of a late sentence: it should be noted, however, in fairness, that said. Passages of this type often bury the contradicting fact behind one of them, precisely because a reader skimming for the argument skips the aside.
Terms to know
- Inconsistency
- Two statements in one text that cannot both hold, or a claim its own evidence does not support.
- Contradiction
- A direct clash between two statements.
- Unsupported conclusion
- A claim the passage's own evidence does not reach.
- Equivocation
- Using one term with two different meanings in the same argument.
- Qualifier
- A word limiting a claim. A qualifier added late can quietly contradict an earlier absolute.
What the TEAS asks most
The same core ideas appear in different wording. If you can answer these without stopping to think, you have what this section requires.
Which two statements in the passage are inconsistent?
Find the pair that cannot both hold. They are usually separated by several sentences.
Which statement is not supported by the rest of the passage?
The conclusion that goes further than the data reported alongside it.
What weakens the author's claim, using the passage itself?
The detail the author includes but does not reckon with — often introduced by however or it should be noted.
Key points
- The inconsistency is between two parts of the text, not between the text and your knowledge.
- Four kinds: contradiction, conclusion beyond evidence, shifting definition, figures that do not reconcile.
- A signalled change of mind is not an inconsistency.
- Contradicting facts are often buried behind however or it should be noted.
- You are asked to identify the mismatch, not to decide which side is correct.
Review quiz
4 questions on this topic, each with the reasoning worked through. Pick an answer to see how it went, or open the explanation straight away.
Read the passage, then answer the questions below
The trust's report on its new triage protocol opens confidently: since the protocol was adopted, no patient has waited longer than four hours in the emergency department. The report credits the protocol with eliminating long waits altogether and recommends adoption at every site in the region. Later, in a section on data completeness, the report explains that patients who leave before being seen are removed from the waiting-time calculation, and that this group has grown from two per cent of attendances to nine. A footnote adds that the four-hour figure covers weekdays only, weekend data having proved difficult to extract from the new system.

Question 1 of 4
Which statement in the report is inconsistent with its opening claim?
Show the answer and explanation
Correct answer: B. That the four-hour figure covers weekdays only
A claim that no patient has waited more than four hours cannot stand alongside an admission that weekends were never measured — the opening asserts something about all patients from partial data. The recommendation is an unsupported conclusion rather than a contradiction, and the remaining two choices are neutral facts about the report.
-
Question 2 of 4
How does the growth in patients leaving before being seen affect the report's claim?
Show the answer and explanation
Correct answer: B. It undermines it, because a growing group of long waits is excluded from the figure.
Patients who leave unseen are precisely those most likely to have waited a long time, and the report removes them from the calculation while their number more than quadruples. Excluding them cannot support the claim, is plainly relevant to waiting times, and says nothing about total attendances.
-
Question 3 of 4
Which is the clearest example of a conclusion that goes beyond the evidence?
Show the answer and explanation
Correct answer: B. That the protocol has eliminated long waits altogether
"Eliminated altogether" is an absolute claim resting on weekday-only data with a growing excluded group, so the evidence cannot reach it. The other three are factual statements the report makes about itself, and it is those very statements that expose the overreach.
-
Question 4 of 4
A reader says the report is inconsistent because emergency departments elsewhere still have long waits. Why is this not an inconsistency in the text?
Show the answer and explanation
Correct answer: A. Because the comparison relies on knowledge from outside the passage rather than a clash within it.
An internal inconsistency is a clash between two parts of the same text, and this objection imports a fact from elsewhere. Other departments are not irrelevant in general — they simply bear on whether the claim is true, not on whether the report contradicts itself, and outside evidence remains legitimate for that separate question.
