NR511 Week 4 Midterm on the First Try: Complete
Exam Review with 125 Practice Questions, Detailed
Rationales, Pharmacology Tables, Clinical Pearls, and
Printable Emergency Cheat Sheet for FNP Students
Question 1: A 43-year-old woman presents with fatigue and intermittent abdominal
pain. As you think through possible causes, you continually ask yourself whether any key
diagnoses are being overlooked and whether each lab you order truly adds value. This
process best describes which concept?
A. SOAP documentation
B. Diagnostic reasoning
C. Medical decision making
D. Differential diagnosis
Answer: B. Diagnostic reasoning
Rationale: Diagnostic reasoning is a reflective, critical-thinking process where the
clinician questions their own thinking to ensure all possibilities are explored and
conclusions are evidence-based .
Question 2: A diagnostic test has very few false negatives. What is the best way to
describe this test?
A. High specificity
B. Low specificity
C. High sensitivity
D. Low sensitivity
Answer: C. High sensitivity
Rationale: A highly sensitive test correctly identifies most people who have the
,condition, resulting in very few false negatives. This makes it a good test to help rule
out a disease when negative .
Question 3: A patient is diagnosed with gastroesophageal reflux disease (GERD), and
his endoscopic report reveals the presence of Barrett's epithelium. Which of the
following information should the clinician include in the explanation of the pathology
report?
A. This is a premalignant tissue.
B. This tissue is resistant to gastric acid.
C. This tissue supports healing of the esophagus.
D. All of the above.
Answer: A. This is a premalignant tissue.
Rationale: Barrett's esophagus is a condition where the normal squamous epithelium of
the esophagus is replaced by columnar epithelium as a response to chronic acid reflux.
It is considered a premalignant condition because it increases the risk of developing
esophageal adenocarcinoma .
Question 4: Which of the following is a crucial element of developing a guideline?
A. Creating a physician expert panel
B. Reviewing the literature with ratings of available evidence
C. Conducting an external review of a guideline
D. Developing evidence-based tables
Answer: B. Reviewing the literature with ratings of available evidence
Rationale: A core component of developing a clinical practice guideline is a systematic
review of the literature, where the available evidence is critically appraised and rated for
quality and strength. This ensures the recommendations are truly evidence-based .
Question 5: A 30-year-old woman reports alternating constipation and diarrhea for six
months, with LLQ cramping relieved by defecation. She denies weight loss, fever, or
bleeding. Physical exam is normal except for mild LLQ tenderness. Which is the MOST
likely primary diagnosis?
A. Irritable bowel syndrome
B. Ulcerative colitis
C. Crohn's disease
D. Acute diverticulitis
Answer: A. Irritable bowel syndrome
Rationale: IBS is a functional disorder characterized by chronic abdominal pain
associated with altered bowel habits (constipation, diarrhea, or both) and the absence of
, "red flag" symptoms like weight loss, fever, or bleeding. The symptoms are often
relieved by defecation .
📚 Focused Study Guide: Key Topics for Weeks 1-4
Use this guide to target your studying on the most frequently tested concepts.
Diagnostic Reasoning & EBP
o Definition: Reflective thinking that questions one's own process to ensure evidence-
based conclusions.
o Components of a Plan: Patient preferences, research evidence, clinical expertise, and
clinical state/circumstances.
Sensitivity, Specificity, and Predictive Value
o Sensitivity: Ability of a test to correctly identify those with the disease. High
Sensitivity = few false negatives (good for ruling out disease).
o Specificity: Ability of a test to correctly identify those without the disease. High
Specificity = few false positives (good for ruling in disease).
o Predictive Value: The likelihood that a patient actually has (or does not have) the
disease, based on the test result and the disease prevalence.
Medical Coding & Documentation
o Medical Coding: Using codes (ICD-10, CPT) to communicate with payers about
procedures and diagnoses.
o Medical Billing: The process of submitting and following up on claims to receive
payment.
o New vs. Established Patient: A new patient has not received professional services from
any provider in the same group practice within the past three years .
o Outpatient E&M Codes: Determined by History, Physical Exam, and Medical Decision
Making (MDM). MDM is based on Risk, Data, and Diagnoses .
Clinical Presentation & SNAPPS
o SNAPPS Acronym: Summarize history and findings, Narrow the differential, Analyze
the differential by comparing/contrasting, Probe the preceptor, Plan the management,
and identify Self-directed learning issues.
Gastrointestinal Conditions
o Acute Gastroenteritis: Most common cause is viral (e.g., norovirus). Management is
supportive with hydration.
o GERD: Step-up therapy after lifestyle changes often starts with an H2-receptor
antagonist (e.g., famotidine).
o IBS vs. IBD:
, IBS (Irritable Bowel Syndrome): A functional disorder. No inflammation or serious
medical consequences. Symptoms (pain, bloating, altered habits) are often relieved with
defecation. Treatment focuses on symptom management.
IBD (Inflammatory Bowel Disease): An immunological disease (Crohn's, Ulcerative
Colitis) with chronic intestinal inflammation. Presents with "red flags" like bloody
diarrhea, fever, weight loss, and elevated inflammatory markers (ESR, CRP) .
o Diverticulitis: Presents with LLQ pain, fever, and leukocytosis. A CT scan with contrast
is often the best test to confirm the diagnosis .
HEENT Conditions
o Hearing Loss:
Conductive: Problem with sound transmission to the inner ear (e.g., cerumen, otitis
media). On Weber test, sound lateralizes to the affected ear.
Sensorineural: Problem with the cochlea or auditory nerve (e.g., aging, noise damage).
On Weber test, sound lateralizes to the unaffected ear.
o Meniere's Disease: Triad of vertigo, hearing loss, and tinnitus.
o Peritonsillar Abscess: Presents with severe unilateral sore throat, "hot potato" voice,
trismus (difficulty opening mouth), and a deviated uvula.
o Otitis Externa: Ear pain with tenderness on traction of the pinna or tragus. The ear
canal is often red and swollen
Additional Practice Questions
Question 6: A 72-year-old man presents with acute onset of vertigo that began 3 hours
ago. He reports nausea and vomiting and is unable to walk unassisted. He has a history
of hypertension and hyperlipidemia. His examination reveals nystagmus that changes
direction with gaze and a positive finger-to-nose test on the left. What is the most
appropriate next step?
A. Prescribe meclizine and send home with fall precautions
B. Perform the Epley maneuver
C. Order a head CT scan without contrast
D. Obtain an emergent MRI brain with diffusion-weighted imaging
Answer: D. Obtain an emergent MRI brain with diffusion-weighted imaging
Rationale: This patient has central vertigo features: acute onset, inability to walk,
direction-changing nystagmus, and cerebellar signs (dysmetria). This is suspicious for
