NSG 550 Diagnostic Reasoning for Nurse Practitioners Comprehensive Exams 1-3 Bundle 2026/2027 | Verified Questions
,INTRODUCTION
This comprehensive examination contains 150 original verified questions covering Exams 1, 2, and 3 of
Wilkes University NSG 550 Diagnostic Reasoning for Nurse Practitioners. The questions are organized
into four core domains: Advanced Health History and Physical Examination (38 questions); Diagnostic
Testing and Laboratory Interpretation (38 questions); Differential Diagnosis and Clinical Decision
Making (37 questions); and Evidence-Based Clinical Care and Pharmacological Integration (37
questions). The content is original and designed to reinforce the official NSG 550 course objectives for
actual exam readiness and clinical proficiency, aligned to the 2026/2027 academic year. Each question is
accompanied by a correct answer designation and a detailed rationale grounded in foundational
diagnostic reasoning and clinical decision-making principles.
ACTUAL QUESTIONS
Domain 1: Advanced Health History and Physical Examination
Question 1. When obtaining a focused history for a patient presenting with chest pain, the
most critical initial question to differentiate cardiac from non-cardiac causes is:
A. Only the patient's age
B. Whether the patient has ever had surgery
C. The quality, location, radiation, precipitating factors, and associated symptoms of the pain
D. The patient's preferred pharmacy
Correct Answer: C
Rationale: A detailed symptom analysis (OPQRST or similar) distinguishes ischemic, pericardial,
musculoskeletal, gastrointestinal, and anxiety-related pain and guides immediate risk stratification and
testing.
Question 2. The chief complaint should be recorded in:
A. Medical terminology exclusively
B. A single diagnostic label
C. The referring clinician's interpretation only
D. The patient's own words whenever possible
Correct Answer: D
Rationale: Documenting the chief complaint in the patient's language preserves the original concern,
reduces bias, and provides a clear starting point for hypothesis generation.
Question 3. In the review of systems, a positive response to unintentional weight loss of
more than 5–10 % of body weight over 6–12 months should prompt consideration of:
A. Only dietary indiscretion
B. Normal aging
C. Malignancy, hyperthyroidism, diabetes, malabsorption, or chronic infection
D. Seasonal variation alone
Correct Answer: C
Rationale: Significant unintentional weight loss is a red-flag symptom that expands the differential to
serious systemic disease and warrants targeted laboratory and imaging evaluation.
Question 4. When examining the skin of a darkly pigmented patient for jaundice, the most
reliable sites to assess are:
A. Sclerae, mucous membranes, and palms/soles under natural light
B. Only the face in artificial light
C. Hair color
NSG 550 Diagnostic Reasoning for Nurse Practitioners Comprehensive Exams 1-3 Bundle 2026/2027 | Verified Questions
, D. Nail thickness
Correct Answer: A
Rationale: Scleral icterus and sublingual or palmar yellowing remain detectable across skin tones and
are less confounded by melanin than general cutaneous inspection.
Question 5. A comprehensive medication history for diagnostic reasoning must include:
A. Only current prescription medications
B. Prescription drugs, over-the-counter agents, herbal supplements, and recent antibiotic exposure
C. Medications taken more than five years ago exclusively
D. The cost of each medication
Correct Answer: B
Rationale: Herbals and OTC products can cause laboratory abnormalities, drug interactions, and
symptoms that mimic disease; recent antibiotics alter culture results and Clostridium difficile risk.
Question 6. The social history element most relevant to assessing risk for latent
tuberculosis is:
A. Country of birth, travel, incarceration, homelessness, and occupational exposures
B. Marital status only
C. Educational level exclusively
D. Preferred hospital
Correct Answer: A
Rationale: TB risk is driven by epidemiology and living conditions. These details determine the need for
interferon-gamma release assay or tuberculin skin testing.
Question 7. When a patient reports 'dizziness,' the examiner must first clarify whether the
symptom is:
A. Always true spinning vertigo
B. Vertigo, presyncope, disequilibrium, or nonspecific lightheadedness
C. Only orthostatic hypotension
D. A psychiatric symptom exclusively
Correct Answer: B
Rationale: The differential and urgency differ markedly among these categories. Precise
characterization directs the neurologic, cardiovascular, or vestibular examination.
Question 8. In the physical examination of a patient with suspected hypothyroidism, the
examiner specifically looks for:
A. Hyperreflexia and warm moist skin
B. Jaundice and spider angiomas
C. Delayed relaxation of deep-tendon reflexes, dry skin, and goiter
D. Clubbing and cyanosis
Correct Answer: C
Rationale: Delayed ankle-jerk relaxation is a classic peripheral sign of hypothyroidism; combined with
skin and thyroid findings it supports the diagnosis before laboratory confirmation.
Question 9. The correct technique for measuring orthostatic vital signs includes:
A. Only a single standing measurement
B. Measuring only while the patient is sitting
C. Ignoring heart-rate change
NSG 550 Diagnostic Reasoning for Nurse Practitioners Comprehensive Exams 1-3 Bundle 2026/2027 | Verified Questions
, D. Recording blood pressure and heart rate after 5 minutes supine, then at 1 and 3 minutes after
standing
Correct Answer: D
Rationale: A drop of ≥20 mm Hg systolic or ≥10 mm Hg diastolic, or a symptomatic rise in heart rate,
defines orthostatic hypotension and guides volume and autonomic evaluation.
Question 10. When palpating the thyroid, the preferred approach for most examiners is:
A. Only anterior palpation with the thumbs
B. Standing behind the patient and using the pads of the fingers while the patient swallows
C. Inspection alone without palpation
D. Deep pressure without swallowing
Correct Answer: B
Rationale: Posterior approach with swallowing allows the gland to rise against the fingers, improving
detection of nodules and diffuse enlargement.
Question 11. A patient history of 'red-flag' back pain symptoms includes all of the following
EXCEPT:
A. History of cancer, unexplained weight loss, or intravenous drug use
B. Saddle anesthesia or bowel/bladder dysfunction
C. Fever or progressive neurologic deficit
D. Pain that improves with activity and worsens with rest in a young adult (suggesting inflammatory
rather than serious spinal pathology)
Correct Answer: D
Rationale: Inflammatory back pain that eases with activity raises suspicion for spondyloarthritis,
whereas the other features are classic red flags for infection, malignancy, or cauda equina syndrome.
Question 12. In the cranial-nerve examination, testing of CN V motor function involves:
A. Asking the patient to raise the eyebrows
B. Shoulder shrug against resistance
C. Palpation of the masseter and temporalis while the patient clenches the teeth
D. Tongue protrusion
Correct Answer: C
Rationale: The motor root of the trigeminal nerve supplies the muscles of mastication; asymmetry or
weakness is readily detected by bilateral palpation during jaw clenching.
Question 13. The most sensitive bedside maneuver for detecting ascites is:
A. Inspection alone
B. Auscultation of bowel sounds
C. Measurement of abdominal girth only
D. Shifting dullness or fluid wave in the presence of a suggestive history
Correct Answer: D
Rationale: Shifting dullness has reasonable sensitivity for moderate ascites; the fluid wave is more
specific but less sensitive. Ultrasound remains the reference standard for small volumes.
Question 14. When performing the Mini-Mental State Examination or similar cognitive
screen, the examiner is primarily assessing:
A. Only long-term memory
B. Orientation, registration, attention, recall, language, and visuospatial function
C. Mood exclusively
