SECTION 2.1
What counts as knowledge?
Evaluate a claim using justification, observations and the patient’s account while making uncertainty explicit.
Learn
Knowing is more demanding than feeling certain. Begin with a claim that could be examined, such as ‘the explanation helped the patient understand’. Ask what would support it: repeating the words may be different from explaining them in one’s own words. This section builds on the distinction between observations and conclusions from lesson 1.
Key concepts and topics
A claim needs a reason
Nursing knowledge supports actions and the reasons for them. A statement such as ‘this intervention helps’ needs a clear outcome, trustworthy observations and a rationale that can be challenged. The slides introduce knowledge as justified true belief; use that as a starting model, not a complete test for every clinical claim. Evidence can be incomplete and should be revised when better findings emerge.
In practice · Instead of ‘we always do it this way,’ ask what outcome the practice seeks and what evidence supports it.
Common misconception · Confidence is not the same as justification; a familiar routine can still be ineffective or harmful.
Justified true belief
The deck introduces the classical idea that knowledge involves a claim that is true, believed and justified. It is useful for asking three separate questions: What exactly is claimed? What supports it? How might it be tested or corrected? This formula is debated in philosophy and should not be treated as a bedside algorithm. Clinical decisions often proceed under uncertainty: a nurse records the strength and limits of the evidence, seeks more information when needed, and revises the plan as the situation changes.
In practice · ‘The patient seems comfortable’ becomes a more useful claim when the nurse asks the patient, observes behaviour and records what was actually seen.
Common misconception · Strong conviction is not by itself evidence that a claim is true.
Patient experience and evidence
Some questions can be measured, such as a change in observed function. Others require asking how a person experiences pain, independence or well-being. Different approaches answer different questions: quantitative studies can estimate patterns across groups; interpretive inquiry can explore meaning in lived experience; realist approaches can investigate underlying processes and context. The labels positivist, realist and interpretivist describe broad research orientations, not three competing bedside tests. Choose methods to fit the question, then make the patient’s account part of the assessment.
In practice · A pain score describes one aspect of change; asking whether the person can rest or carry out a valued activity adds meaning to that score.
Common misconception · Respecting lived experience does not mean abandoning observation or research.
Key facts to remember
- Certainty describes confidence; justification gives reasons.
- Choose evidence that answers the question actually asked.
CONCEPTS IN CONTEXT
Explore the ideas
Follow the steps for the claim ‘the patient understands’. Select a step to see what to check.
State the claim
A proposition is a statement that can be true or false.
In this situation · ‘The patient can explain the plan’ is more specific than ‘everything is fine’.

What counts as knowledge?
The deck’s overlapping circles of truth, belief and justification introduce a classical model rather than a complete philosophical solution. An honestly held belief can be false; a lucky correct guess can lack justification. In care, we rarely know everything before deciding, so we state the evidence and its limits. Match the research approach to the question: counting outcomes answers a different question from exploring what the outcome means in a person’s life. Neither a number nor a personal account should be asked to answer a question it cannot answer alone.
Core concepts defined
- State the claim
- A proposition is a statement that can be true or false.
- Seek support
- Justification connects a claim to relevant reasons and evidence.
- Consider limits
- A limitation identifies what the available evidence does not establish.
- Review
- Revise the judgement when new observations or concerns arise.

Reason through the situation
A patient nods during an explanation. A student records ‘understands everything’. Later the patient asks a question that reveals confusion.
- Identify the actual observation: the patient nodded. Nodding may show attention, agreement or politeness; it is insufficient evidence for complete understanding.
- Seek relevant evidence. Ask the patient to explain the plan in their own words, in a respectful way that checks your explanation rather than testing their worth. Listen for the specific unclear point.
- Revise the record and the teaching. Document what the patient could explain and what needs follow-up. A correction improves the knowledge claim; it does not mean that listening to the first observation was useless.

Reveal a model explanation
Only that nodding was observed. The reason for it and the depth of understanding still need to be explored.
