WGU D117 - Advanced Health Assessment for the Advanced
Practice Nurse | Complete Video Script & Health Assessment
Techniques Checklist | 2026 Updated.
This exam assesses graduate-level advanced practice nursing competencies in health assessment foundations and
clinical reasoning, emphasizing evidence-based physical examination techniques, diagnostic reasoning, and
clinical decision-making. Questions require synthesis of subjective and objective data, application of Bayesian
principles, and critical appraisal of assessment findings to formulate accurate diagnoses and management plans.
It contains 144 multiple-choice questions, each with four distractors and a fully worked rationale that explains
why the keyed answer is correct. Content is organized into 12 focused sections: Advanced Health Assessment
Foundations and Clinical Reasoning, Comprehensive Health History and Interviewing Techniques, General
Survey, Vital Signs, and Pain Assessment, Skin, Hair, and Nails Assessment, Head, Eyes, Ears, Nose, and Throat
(HEENT) Assessment, Cardiovascular and Peripheral Vascular Assessment, Respiratory and Thoracic
Assessment, Abdominal and Gastrointestinal Assessment, Musculoskeletal and Neurological Assessment, Mental
Health, Psychosocial, and Cultural Assessment, Special Populations and Lifespan Considerations (Pediatrics,
Older Adults, Pregnancy), Documentation, Differential Diagnosis, and Clinical Decision-Making. Targeted
learning outcomes include: Demonstrate advanced clinical reasoning by integrating history, physical
examination, and diagnostic data to prioritize differential diagnoses.; Apply evidence-based physical examination
techniques and interpret findings with sensitivity, specificity, and predictive values in mind.; Critically evaluate
Section 1: Advanced Health Assessment Foundations and Clinical Reasoning (Questions 1-12)
1 Which component of the clinical reasoning cycle most directly mitigates
premature closure?
A) Generating a comprehensive differential diagnosis before finalizing
B) Relying on initial pattern recognition to expedite diagnosis
C) Anchoring on the most salient finding from the history
D) Using a single pivotal test to confirm the leading diagnosis
Answer: A
Rationale: Premature closure occurs when a clinician settles on a diagnosis
before fully considering alternatives. Generating a comprehensive differential
diagnosis forces consideration of other possibilities and is a key debiasing
strategy. Pattern recognition, anchoring, and single-test confirmation can all
contribute to premature closure if not balanced with broader inquiry.
2 A screening test has sensitivity 90% and specificity 80%. In a population
with 1% prevalence, what is the approximate positive predictive value
(PPV)?
A) 4.3%
B) 10%
C) 45%
,D) 90%
Answer: A
Rationale: PPV = (sensitivity × prevalence) / [(sensitivity × prevalence) + ((1 -
specificity) × (1 - prevalence))]. Plugging in: (0.9 × 0.01) / [(0.9 × 0.01) + (0.2
× 0.99)] = 0.009 / (0.009 + 0.198) 0.043, or 4.3%. This illustrates that even
highly sensitive tests have low PPV in low-prevalence settings.
3 Which statement best reflects the concept of diagnostic stewardship in
advanced health assessment?
A) Ordering all available tests to avoid missing any diagnosis
B) Using the most sensitive test regardless of cost or invasiveness
C) Selecting tests based on pretest probability to maximize value and
minimize harm
D) Deferring diagnostic testing until symptoms become severe
Answer: C
Rationale: Diagnostic stewardship involves choosing the right test for the right
patient at the right time, guided by pretest probability, to optimize outcomes
and reduce unnecessary testing. Ordering all tests, using overly sensitive tests
indiscriminately, or delaying testing can lead to harm, cost, and false positives.
4 Which of the following best exemplifies a Type 1 error in clinical
decision-making?
A) Failing to diagnose a condition that is present
B) Diagnosing a condition that is not actually present
C) Choosing a test with low sensitivity
D) Ignoring a patient's family history
Answer: B
Rationale: A Type 1 error (false positive) occurs when a clinician concludes a
condition exists when it does not. Type 2 error is failing to detect a true
condition. Low sensitivity and ignoring history increase the risk of Type 2
errors but are not themselves Type 1 errors.
5 Which clinical reasoning model emphasizes iterative hypothesis generation
and testing during the patient encounter?
A) Bayesian reasoning
B) Hypothetico-deductive model
,C) Pattern recognition
D) Narrative medicine
Answer: B
Rationale: The hypothetico-deductive model involves generating hypotheses
early and testing them through further data collection. Bayesian reasoning
updates probabilities but is not a model of hypothesis testing per se; pattern
recognition relies on immediate Gestalt; narrative medicine focuses on
understanding the patient's story.
6 Which of the following is the most effective strategy to reduce diagnostic
error related to availability bias?
A) Considering only the most recent similar cases
B) Using a systematic differential diagnosis checklist
C) Relying on intuitive judgment
D) Limiting the differential to common conditions
Answer: B
Rationale: Availability bias involves overestimating the likelihood of diagnoses
that come to mind easily. A systematic checklist ensures all relevant
possibilities are considered, counteracting this bias. The other options either
reinforce bias or limit thoroughness.
7 In the context of advanced health assessment, which statement about the
'review of systems' is most accurate?
A) It is a substitute for the physical examination
B) It focuses exclusively on the chief complaint
C) It systematically screens for symptoms across all body systems
D) It is only relevant for hospitalized patients
Answer: C
Rationale: The review of systems is a systematic inquiry about symptoms in
each body system to uncover additional issues and guide the physical
examination. It does not replace the physical exam, is not limited to the chief
complaint, and is relevant in all settings.
8 Which of the following best describes the purpose of a 'pertinent negative' in
clinical documentation?
A) To document normal findings only
, B) To record symptoms the patient denies that are relevant to the differential
C) To list all possible diagnoses
D) To summarize the patient's social history
Answer: B
Rationale: Pertinent negatives are symptoms or findings that are absent but
important for narrowing the differential diagnosis. They are not merely normal
findings, a list of diagnoses, or a social history summary.
9 Which of the following best illustrates the use of a likelihood ratio in clinical
decision-making?
A) A test with LR+ of 10 strongly increases the probability of disease
B) A test with LR- of 0.1 strongly increases the probability of disease
C) A test with LR+ of 1 has high diagnostic value
D) A test with LR- of 10 rules in disease
Answer: A
Rationale: A positive likelihood ratio (LR+) greater than 10 substantially
increases the post-test probability of disease. LR- of 0.1 strongly decreases
probability; LR+ of 1 provides no change; LR- of 10 is not meaningful for
ruling in.
10 Which best explains why a positive likelihood ratio of 10 most strongly
supports diagnostic reasoning?
A) It confirms the diagnosis independent of pretest probability.
B) It substantially increases post-test probability from most pretest levels.
C) It rules out disease when the test result is negative.
D) It reflects high sensitivity rather than specificity.
Answer: B
Rationale: A positive likelihood ratio of 10 means a positive result is 10 times
more likely in diseased than nondiseased patients, producing a large upward
shift in post-test probability via Bayesian reasoning. It does not confirm
diagnosis independent of pretest probability, does not describe negative-result
rule-out, and is driven by both sensitivity and specificity, not sensitivity alone.
11 During hypothesis-driven interviewing, which action best demonstrates
calibrated clinical reasoning?
A) Broadening the differential after each reassuring finding.
