Exam!!! 2026
A patient presents with fatigue, weakness, and dizziness. Which action should the nurse take
first when beginning the diagnostic reasoning process?
A. Develop a treatment plan
B. Collect relevant assessment data
C. Identify the final diagnosis
D. Select the appropriate medication
Answer: B. Collect relevant assessment data
Rationale: Diagnostic reasoning begins with systematic collection of relevant subjective and
objective information before hypotheses or diagnoses can be developed.
Which finding represents subjective data?
A. Blood pressure of 148/88 mmHg
B. Temperature of 38.2°C
C. Patient reports feeling nauseated
D. Respiratory rate of 24/min
Answer: C. Patient reports feeling nauseated
Rationale: Subjective data are symptoms or experiences reported by the patient, whereas vital
signs and observed findings are objective data.
Which finding is an example of objective data?
A. "My chest feels tight."
B. "I feel weak."
C. "I have been coughing all night."
D. Oxygen saturation of 89%
Answer: D. Oxygen saturation of 89%
Rationale: Objective data are measurable or observable findings obtained through assessment,
examination, or diagnostic testing.
A nurse notices that a patient's current symptoms do not fit the initial hypothesis. What is
the most appropriate action?
,A. Ignore the conflicting findings
B. Reassess the patient and reconsider the hypothesis
C. Document the original hypothesis as confirmed
D. Wait until the next shift to investigate
Answer: B. Reassess the patient and reconsider the hypothesis
Rationale: Conflicting or unexpected findings should prompt reassessment and modification of
diagnostic hypotheses.
Which question best demonstrates effective clinical inquiry?
A. "Why does this patient always have problems?"
B. "What additional findings would support this hypothesis?"
C. "Which diagnosis do I usually see with this symptom?"
D. "What diagnosis should I document immediately?"
Answer: B. "What additional findings would support this hypothesis?"
Rationale: Effective clinical inquiry involves actively seeking evidence that supports or
challenges possible explanations.
A patient reports abdominal pain. Which assessment finding is most important for narrowing
possible causes?
A. Favorite foods
B. Location and characteristics of the pain
C. Preferred sleeping position
D. Occupation
Answer: B. Location and characteristics of the pain
Rationale: Location, quality, severity, timing, and associated factors provide important
diagnostic information.

A. Ask only yes-or-no questions
B. Allow the patient to describe the chief concern in their own words
C. Focus exclusively on the current medication list
D. Begin with highly technical questions

D. Mild fatigue
Answer: B. Oxygen saturation of 84%
Rationale: Markedly decreased oxygen saturation indicates impaired oxygenation and requires
prompt evaluation.
Which finding should cause the nurse to question a preliminary diagnosis?
A. Findings that are consistent with the diagnosis
B. A new finding that contradicts the expected pattern
C. A patient's demographic information
D. A previously documented diagnosis
Answer: B. A new finding that contradicts the expected pattern
Rationale: Contradictory findings can indicate that the initial hypothesis is incomplete or
incorrect.
What is the primary purpose of generating multiple diagnostic hypotheses?
A. To delay treatment
B. To prevent premature closure
C. To eliminate the need for assessment
D. To avoid communicating with the patient
Answer: B. To prevent premature closure
Rationale: Considering multiple plausible explanations reduces the risk of settling on an
incorrect diagnosis too early.
Which statement best describes premature closure?
A. Continuing to reassess a patient
B. Accepting an initial diagnosis without adequately considering alternatives
C. Collecting additional objective data
D. Asking another clinician for input
Answer: B. Accepting an initial diagnosis without adequately considering alternatives
Rationale: Premature closure occurs when a clinician stops diagnostic reasoning too soon after
accepting an initial explanation.
