NR 511 ADVANCED CLINICAL
DIAGNOSIS AND MANAGEMENT FINAL
EXAM
1. A 45-year-old male presents with sudden onset of severe pain in his right great toe. On
examination, the joint is erythematous, swollen, and exquisitely tender. Which of the
following is the most definitive diagnostic test for the suspected condition?
A. Joint aspiration and synovial fluid analysis
B. Serum uric acid level
C. X-ray of the foot
D. C-reactive protein (CRP) level
Answer: A
Conceptual Explanation: Synovial fluid analysis showing negatively birefringent needle-
shaped crystals is the gold standard for diagnosing gout. Serum uric acid can be normal
during an acute attack.
2. During a physical exam, a clinician performs the Lachman test on a patient who sustained a
knee injury during soccer. The clinician notes significant laxity. This finding is most suggestive
of an injury to which structure?
A. Medial collateral ligament (MCL)
,B. Posterior cruciate ligament (PCL)
C. Anterior cruciate ligament (ACL)
D. Medial meniscus
Answer: C
Conceptual Explanation: The Lachman test is considered the most sensitive physical
exam maneuver for detecting an ACL tear.
3. A 68-year-old female presents with new-onset temporal headache, jaw claudication, and
scalp tenderness. Which diagnostic test should be ordered immediately to prevent
permanent vision loss?
A. CT scan of the head
B. Lumbar puncture
C. Erythrocyte sedimentation rate (ESR)
D. Carotid ultrasound
Answer: C
Conceptual Explanation: Temporal arteritis (Giant Cell Arteritis) is suspected. A highly
elevated ESR or CRP supports the diagnosis, followed by a temporal artery biopsy, but
immediate treatment with steroids is needed to prevent blindness.
, 4. A patient presents with a ‘herald patch’ on the trunk, followed by a ‘Christmas tree’
distribution of smaller maculopapular lesions. What is the most likely diagnosis?
A. Tinea corporis
B. Secondary syphilis
C. Psoriasis
D. Pityriasis rosea
Answer: D
Conceptual Explanation: Pityriasis rosea characteristically begins with a herald patch
followed by a Christmas tree distribution of lesions along skin cleavage lines.
5. Which of the following spirometry results is diagnostic for Chronic Obstructive Pulmonary
Disease (COPD)?
A. Peak Expiratory Flow Rate (PEFR) variability > 20%
B. FEV1 increase of 12% after albuterol
C. Total Lung Capacity (TLC) < 80% predicted
D. Post-bronchodilator FEV1/FVC ratio < 0.70
Answer: D
Conceptual Explanation: The GOLD guidelines define COPD by a persistent airflow
limitation where the post-bronchodilator FEV1/FVC ratio is less than 0.70.
