NUR 6130 — Exam 1
Advanced Clinical Reasoning, Diagnostic Complexity, Evidence Synthesis & Chronic Disease Assessment
75 Questions | 120 Minutes
Domain 1
Advanced Clinical Reasoning & Diagnostic Complexity
Q1. A 58-year-old male presents with acute onset severe headache, neck stiffness, and
photophobia. Vital signs show BP 180/110, HR 98, T 38.2C. Which diagnostic approach
best applies the 'worst-first' principle in differential diagnosis?
A) Order a complete metabolic panel and observe for 24 hours
B) Immediately perform a non-contrast CT head to rule out subarachnoid
hemorrhage before considering more common etiologies such as viral meningitis
C) Prescribe analgesics and schedule a follow-up in one week
D) Perform a lumbar puncture without prior imaging
Correct Answer: B
Rationale: The 'worst-first' principle requires evaluating life-threatening conditions before more
common but less dangerous etiologies. Subarachnoid hemorrhage (SAH) has high mortality if
missed, making non-contrast CT head the immediate priority. A normal CT does not exclude SAH
entirely, but it is the essential first step. Option A delays critical diagnosis. Option C is dangerous
given red flag symptoms. Option D risks brain herniation if intracranial pressure is elevated from
a mass or hemorrhage; imaging must precede lumbar puncture.
Q2. A 42-year-old female presents with fatigue, weight gain, cold intolerance, and
constipation. TSH is 22 mIU/L (normal 0.4-4.0) and free T4 is low. In applying
probabilistic reasoning, which condition has the highest pre-test probability?
A) Pituitary adenoma causing secondary hypothyroidism
B) Primary hypothyroidism (Hashimoto thyroiditis)
C) Euthyroid sick syndrome
D) Subacute thyroiditis
Correct Answer: B
Rationale: The elevated TSH with low free T4 confirms primary hypothyroidism. Hashimoto
thyroiditis is the most common cause of primary hypothyroidism in iodine-sufficient regions,
giving it the highest pre-test probability. Option A (secondary hypothyroidism) would present
with low or inappropriately normal TSH with low T4. Option C occurs in the setting of acute
, systemic illness, not with this chronic presentation. Option D typically presents with transient
hyperthyroidism followed by hypothyroidism and a tender thyroid.
Q3. A differential diagnosis framework for a 65-year-old with acute dyspnea should
categorize possibilities into which prioritized tiers?
A) Cardiac causes only, then pulmonary causes
B) Life-threatening (tension pneumothorax, massive PE, acute MI with pulmonary
edema), common (COPD exacerbation, pneumonia, heart failure), and uncommon
(pulmonary vasculitis, hepatopulmonary syndrome)
C) All causes ranked alphabetically
D) Only the most likely diagnosis should be considered first
Correct Answer: B
Rationale: A structured differential diagnosis framework organizes conditions into life-
threatening, common, and uncommon categories to ensure critical conditions are not missed
while efficiently evaluating probable etiologies. This tiered approach balances diagnostic
thoroughness with clinical urgency. Option A is too narrow and excludes non-cardiopulmonary
causes. Option C lacks clinical prioritization. Option D risks premature closure, a common
cognitive error in diagnostic reasoning.
Q4. When evaluating a patient with chest pain, a clinician uses the Wells Score for
pulmonary embolism. This is an example of which clinical reasoning tool?
A) Heuristic reasoning based on pattern recognition alone
B) A clinical prediction rule that integrates multiple clinical variables to estimate pre-
test probability and guide diagnostic test ordering
C) A treatment algorithm that determines anticoagulation dosing
D) A patient-reported outcome measure
Correct Answer: B
Rationale: The Wells Score is a validated clinical prediction rule that combines clinical variables
(signs of DVT, heart rate, immobilization, previous PE/DVT, hemoptysis, malignancy) to
categorize pre-test probability as low, moderate, or high, guiding whether to pursue imaging (CT
angiography) or D-dimer testing. Option A describes intuitive reasoning, not a structured rule.
Option C describes a treatment protocol, not a probability assessment. Option D is unrelated to
diagnostic probability estimation.
Q5. A 72-year-old male with COPD, heart failure, diabetes, and osteoarthritis presents with
worsening dyspnea. His medication list includes 14 medications. Which cognitive bias is
most likely to affect diagnostic reasoning in this patient?
A) Anchoring bias due to the multiple comorbidities
B) Premature closure driven by the complexity and tendency to attribute symptoms
to the most familiar condition (e.g., assuming COPD exacerbation without
considering new heart failure decompensation)
C) Base-rate neglect, because the patient has too many conditions
D) Availability bias, which only applies to rare diseases
Correct Answer: B
Rationale: In multimorbid patients, premature closure is a significant risk because clinicians may
attribute new symptoms to an existing diagnosis without considering alternative explanations.
This 'diagnostic momentum' can lead to missed new conditions. Anchoring bias (Option A) is
related but refers more specifically to locking onto initial information. Base-rate neglect (Option
C) involves ignoring prevalence data. Availability bias (Option D) applies to both common and
rare conditions based on recent recall, not just rare diseases.
, Q6. A test has a sensitivity of 95% and specificity of 90% for detecting Disease X. The
disease prevalence in the tested population is 2%. What is the approximate positive
predictive value (PPV)?
A) Approximately 95%
B) Approximately 16%
C) Approximately 90%
D) Approximately 50%
Correct Answer: B
Rationale: Using a 2x2 table with 10,000 patients: 200 have Disease X (2% prevalence). True
positives = 200 x 0.95 = 190. False positives = 9,800 x 0.10 = 980. PPV = TP/(TP+FP) =
190/(190+980) = 190/1,170 = approximately 16%. This demonstrates that even with good
sensitivity and specificity, a low prevalence dramatically reduces PPV, a critical concept for
advanced practice nurses selecting and interpreting diagnostic tests.
Q7. A negative D-dimer result in a patient with low pre-test probability for pulmonary
embolism has a negative likelihood ratio (LR-) of 0.1. How should this result influence
clinical decision-making?
A) The result is irrelevant because D-dimer is not specific enough
B) A negative D-dimer with LR- of 0.1 substantially reduces the post-test probability
of PE, making it reasonable to withhold anticoagulation and avoid further imaging in
a low-risk patient
C) A CT angiogram should still be performed regardless
D) The patient should be started on anticoagulation empirically
Correct Answer: B
Rationale: An LR- of 0.1 means a negative result is 10 times more likely in a patient without PE
than with PE, substantially lowering post-test probability and supporting the decision to not
pursue further testing in low-risk patients. This is the evidence-based application of Bayesian
reasoning. Option A misunderstands the value of LR- in clinical context. Option C contradicts
evidence-based guidelines that support ruling out PE with negative D-dimer in low-risk patients.
Option D is inappropriate without confirmed diagnosis.
Q8. A 55-year-old female presents with generalized fatigue, morning stiffness, and bilateral
shoulder and hip girdle pain. ESR is 85 mm/hr. The clinician considers polymyalgia
rheumatica (PMR) and giant cell arteritis (GCA). Which diagnostic principle best guides
this evaluation?
A) PMR and GCA are unrelated conditions requiring separate evaluations
B) Recognizing the spectral relationship between PMR and GCA, evaluating for GCA
symptoms (headache, jaw claudication, visual changes) because GCA is the life-
threatening manifestation requiring immediate corticosteroids and possible
temporal artery biopsy
C) Starting low-dose corticosteroids and monitoring response is sufficient without further
evaluation
D) GCA can only be diagnosed with an MRI
Correct Answer: B
Rationale: PMR and GCA exist on a clinical spectrum; up to 30% of PMR patients develop GCA,
and GCA can cause irreversible vision loss. The diagnostic principle requires evaluating for the
more serious condition within the spectrum. Option A is incorrect because they share
pathophysiology. Option C is dangerous because GCA requires higher-dose corticosteroids and
urgent evaluation. Option D is incorrect because temporal artery biopsy remains the diagnostic
standard, not MRI.
