Advanced Clinical Diagnosis | Study Guide & Answers | Chamberlain University
Question 1
A 52-year-old male patient presents to the clinic with a 4-month history of progressive
exertional dyspnea and a dry, hacking cough. On physical examination, the clinician
auscultates fine, Velcro-like inspiratory crackles at both lung bases. A high-resolution
chest CT reveals subpleural reticular opacities and peripheral honeycombing. Which of
the following conditions is the most likely diagnosis?
A. Chronic obstructive pulmonary disease (COPD)
B. Idiopathic pulmonary fibrosis (IPF)
C. Acute lobar pneumonia
D. Sarcoidosis
Answer: B. Idiopathic pulmonary fibrosis (IPF)
Rationale: Idiopathic pulmonary fibrosis is a chronic, progressive fibrosing interstitial
pneumonia. Its classic clinical presentation features exertional dyspnea, a non-
productive cough, and bibasilar fine inspiratory Velcro crackles. High-resolution CT
imaging confirms the diagnosis by demonstrating peripheral reticular opacities
accompanied by architectural distortion and honeycombing.
Question 2
During a routine structural assessment of a 4-month-old infant, the nurse practitioner
notes that the posterior fontanelle is completely closed, while the anterior fontanelle
remains soft, flat, and open. What is the appropriate clinical interpretation of this
finding?
A. Craniosynostosis requiring immediate neurosurgical referral
B. Normal physiological development for this infant's age
,C. Severe microcephaly secondary to intrauterine growth restriction
D. Early sign of rickets or congenital hypothyroidism
Answer: B. Normal physiological development for this infant's age
Rationale: The posterior fontanelle normally closes by 1 to 2 months of age, while the
larger anterior fontanelle typically remains open to accommodate rapid developmental
brain growth, closing between 9 and 18 months of age. Therefore, a closed posterior
and an open anterior fontanelle at 4 months is a normal physiological finding.
Question 3
A 65-year-old female patient presents to the primary care clinic with severe, throbbing
unilateral left temple pain, scalp tenderness when brushing her hair, and jaw
claudication while chewing food. She notes a brief episode of blurred vision in her left
eye this morning. On physical exam, her left temporal artery is prominent, nodular, and
non-pulsatile. What immediate clinical action is paramount to prevent permanent
blindness?
A. Order an outpatient duplex ultrasound of the bilateral temporal arteries
B. Initiate immediate empiric high-dose systemic corticosteroid therapy
C. Schedule an urgent temporal artery biopsy for the following week
D. Prescribe low-dose Aspirin 81mg and request a neurology consult
Answer: B. Initiate immediate empiric high-dose systemic corticosteroid therapy
Rationale: The patient’s presentation is highly suspicious for Giant Cell (Temporal)
Arteritis, a granulomatous vasculitis targeting large and medium-sized arteries. Because
ischemic optic neuropathy can cause sudden, irreversible blindness, immediate empiric
treatment with high-dose systemic corticosteroids (e.g., Prednisone 40–60 mg daily) is
mandated before waiting for ultrasound or biopsy results.
Question 4
A 43-year-old male patient presents to the clinic with an intensive, throbbing headache
localized around his left orbit that woke him from sleep last night. He reports that the
headache lasted 45 minutes and was accompanied by prominent tearing (lacrimation)
and rhinorrhea from his left eye and nares. He notes having had three identical
episodes over the past 48 hours. What is the abortive treatment of choice for an acute
attack of this condition?
A. High-dose oral Ibuprofen 800mg
B. Administration of 100% oxygen at 12–15 L/min via a non-rebreather mask
,C. Oral Amitriptyline 25mg at bedtime
D. Intramuscular Botulinum toxin injections along the trigeminal pathways
Answer: B. Administration of 100% oxygen at 12–15 L/min via a non-rebreather
mask
Rationale: The patient's clinical presentation matches cluster headaches, which are
severe, unilateral, trigeminal autonomic cephalgias that occur in clusters and feature
ipsilateral autonomic signs (lacrimation, rhinorrhea, miosis, or ptosis). The absolute first-
line abortive treatment is the inhalation of 100% oxygen via a non-rebreather face mask
for 15–20 minutes.
Question 5
An advanced practice nurse is reviewing the arterial blood gas (ABG) results of a
patient admitted with severe, intractable vomiting secondary to a high-grade mechanical
bowel obstruction. The results indicate a pH of 7.52, a PaCO2 of 48 mmHg, and a
HCO3- of 36 mEq/L. How should this acid-base imbalance be classified?
A. Partially compensated respiratory acidosis
B. Fully compensated metabolic acidosis
C. Uncompensated respiratory alkalosis
D. Partially compensated metabolic alkalosis
Answer: D. Partially compensated metabolic alkalosis
Rationale: A pH of 7.52 confirms an alkalemia (>7.45). The HCO3- is elevated at 36
mEq/L (>26 mEq/L), identifying the primary process as metabolic alkalosis, driven by
the loss of gastric hydrochloric acid from vomiting. The PaCO2 is elevated at 48 mmHg
(>45 mmHg) as a compensatory hypoventilatory response to retain acid, making it
partially compensated since the pH has not yet returned to the normal range.
Question 6
A 31-year-old female patient presents with a 3-month history of fatigue, generalized joint
pain, and an erythematous maculopapular rash across her malar eminences and nasal
bridge that spares the nasolabial folds. Laboratory testing reveals a positive antinuclear
antibody (ANA) titer of 1:320. Which of the following additional serological markers is
the most specific for confirming a diagnosis of Systemic Lupus Erythematosus (SLE)?
A. Rheumatoid Factor (RF)
B. Anti-Double-Stranded DNA (anti-dsDNA)
C. Anti-cyclic citrullinated peptide (anti-CCP)
D. Anti-Scl-70 (anti-topoisomerase I)
, Answer: B. Anti-Double-Stranded DNA (anti-dsDNA)
Rationale: While the antinuclear antibody (ANA) test is highly sensitive for SLE (>95%),
it has poor specificity and can be positive in many autoimmune conditions. Anti-Double-
Stranded DNA (anti-dsDNA) and Anti-Smith (anti-Sm) antibodies are highly specific for
SLE and serve as confirmatory diagnostic markers.
Question 7
A patient presents with progressive dyspnea and productive cough. Chest percussion
reveals a localized area of flat-like dullness over the right lower lung lobe. Auscultation
over this exact zone reveals bronchial breath sounds, increased tactile fremitus, and
positive egophony (E-to-A changes). What pulmonary condition matches this clinical
finding?
A. Large left-sided pneumothorax
B. Acute lobar consolidation (Pneumonia)
C. Chronic pleural effusion
D. Severe diffuse emphysema
Answer: B. Acute lobar consolidation (Pneumonia)
Rationale: Lobar consolidation from pneumonia replaces air spaces with inflammatory
exudate, which conducts sound waves more effectively through solid media. This
produces characteristic physical signs over the consolidated lobe: dullness to
percussion, bronchial breath sounds, increased tactile fremitus, and positive egophony.
A pleural effusion also yields dullness but would cause a decrease or absence of breath
sounds and decreased fremitus due to fluid insulating the lung from the chest wall.
Question 8
A 19-year-old female college student is brought to the health center presenting with an
acute onset of high fever, severe headache, photophobia, and a petechial skin rash
localized across her trunk and lower extremities. During the neurological exam, the
clinician notes rigid resistance and pain when attempting to flex the patient's neck
forward. What is the definitive diagnostic procedure required to confirm the suspected
condition?
A. Non-contrast computed tomography (CT) scan of the head
B. Lumbar puncture with cerebrospinal fluid (CSF) analysis
C. Blood cultures and a complete metabolic panel
D. High-resolution magnetic resonance imaging (MRI) of the brainstem
Answer: B. Lumbar puncture with cerebrospinal fluid (CSF) analysis
