Guaranteed – A+ Graded
Section 1: Health Assessment & Differential Diagnosis (Questions 1-25)
Q1: A 65-year-old male presents with acute onset of right lower quadrant pain, fever, and
rebound tenderness. The nurse practitioner (NP) suspects appendicitis. Which diagnostic test has
the highest sensitivity for confirming this diagnosis?
A. Computed Tomography (CT) scan of the abdomen/pelvis [CORRECT]
B. Ultrasound of the right upper quadrant
C. Complete Blood Count (CBC)
D. Urinalysis
Correct Answer: A
Rationale: CT scan is the gold standard for diagnosing appendicitis in adults due to its high
sensitivity (94-98%) and specificity. Ultrasound is often used in children or pregnant women to
avoid radiation. CBC and urinalysis are supportive but not diagnostic.
Q2: When evaluating a diagnostic test using Bayes' theorem, which test characteristic is most
important for ruling out a disease?
A. High Specificity
B. High Sensitivity (SNOUT) [CORRECT]
C. High Positive Predictive Value
D. High Negative Predictive Value
Correct Answer: B
Rationale: A test with high sensitivity (SNOUT: Sensitivity rules OUT) is best used to rule out a
disease because a negative result effectively means the disease is likely absent. High specificity
(SPIN: Specificity rules IN) is used to rule in a disease.

Q3: According to the USPSTF, at what age should colorectal cancer screening begin for average-
risk adults?
A. 40 years
B. 45 years [CORRECT]
C. 50 years
D. 55 years
Correct Answer: B
Rationale: In 2021, the USPSTF updated the recommendation to start screening at age 45 (down
from 50) due to increasing incidence in younger adults. Screening continues until age 75.
Q4: A 45-year-old female presents with a breast lump. It is mobile, firm, and non-tender. There is
no family history of breast cancer. The most likely diagnosis is:
A. Fibroadenoma [CORRECT]
B. Invasive Ductal Carcinoma
C. Fibrocystic changes
D. Cyst
Correct Answer: A
Rationale: Fibroadenomas are benign tumors common in young women, characterized by a firm,
mobile, rubbery mass. Cancer is often fixed/hard; cysts are often fluctuant/tender; fibrocystic
changes are usually bilateral and cyclical.
Q5: A patient presents with a "thunderclap" headache described as the "worst headache of my
life." The NP must immediately rule out:
A. Migraine with aura
B. Subarachnoid Hemorrhage (SAH) [CORRECT]
C. Tension Headache
D. Cluster Headache
Correct Answer: B
,3
Rationale: Thunderclap headache is a classic presentation of SAH (ruptured aneurysm). It is a
medical emergency requiring immediate CT scan. Migraines and tension headaches build up
gradually.
Q6: Which of the following Likelihood Ratios (LR+) indicates the greatest increase in the
probability of a disease being present?
A. LR+ = 2
B. LR+ = 5
C. LR+ = 10 [CORRECT]
D. LR+ = 0.1
Correct Answer: C
Rationale: An LR+ > 10 indicates a large and often conclusive increase in the likelihood of the
disease. LR+ < 1 decreases the probability (LR-).
Q7: A 55-year-old male smoker presents with hemoptysis and weight loss. Chest X-ray reveals a
central mass. The most likely diagnosis is:
A. Small Cell Lung Cancer
B. Squamous Cell Carcinoma [CORRECT]
C. Adenocarcinoma
D. Mesothelioma
Correct Answer: B
Rationale: Squamous cell carcinoma is strongly associated with smoking and typically presents
as a central mass with hemoptysis. Adenocarcinoma is usually peripheral. Small cell is also
central but is the most aggressive and associated with paraneoplastic syndromes.
Q8: When assessing jugular venous distension (JVD), the patient should be positioned at:
A. 15 degrees
B. 30 to 45 degrees [CORRECT]
C. 90 degrees
, 4
D. Supine
Correct Answer: B
Rationale: The correct position to assess JVD is 30 to 45 degrees. In this position, the top of the
venous column is normally no more than 3-4 cm above the sternal angle.
Q9: A patient with a known history of rheumatoid arthritis presents with shortness of breath.
Chest X-ray shows interstitial fibrosis. This is an example of:
A. Extra-articular manifestation [CORRECT]
B. Osteoarthritis complication
C. Reiter's syndrome
D. Psoriatic arthritis
Correct Answer: A
Rationale: RA is a systemic autoimmune disease. Pulmonary involvement (interstitial lung
disease, pleural effusions) is a common extra-articular manifestation.
Q10: The USPSTF recommends screening for depression in:
A. Only adults with a chronic illness.
B. Only pregnant women.
C. All adults, including pregnant and postpartum persons. [CORRECT]
D. Only adults over age 65.
Correct Answer: C
Rationale: The USPSTF recommends screening for major depressive disorder (MDD) in the
general adult population, including pregnant and postpartum women.
Q11: A patient presents with acute monoarthritis of the first metatarsophalangeal joint (podagra).
Aspiration reveals negatively birefringent needle-shaped crystals. The diagnosis is:
A. Gout [CORRECT]
B. Pseudogout (CPPD)
C. Septic Arthritis
