Practice Case Studies, Clinical Reasoning,
Diagnostic Testing, and Treatment Plans —
Post University
This original practice question bank is designed to support study of N512 pulmonary
and infectious-disease case studies. It focuses on distinguishing bacterial from viral
pharyngitis, interpreting tuberculosis screening results, selecting appropriate
diagnostic tests, and developing safe, evidence-informed treatment plans.
The questions emphasize clinical presentation, differential diagnosis, laboratory
interpretation, medication selection, patient education, infection prevention, follow-up,
and recognition of complications. They are educational practice questions, not an
official Post University examination or verified answer key. Treatment decisions
should be individualized to the patient’s age, medical history, allergies, pregnancy
status, local guidelines, and diagnostic findings.

QUESTIONS 1–100
Domain 1: Pulmonary Assessment and Clinical
Reasoning
Q1. A 24-year-old patient presents with a sore throat, cough, rhinorrhea, and
hoarseness. Which diagnosis is most consistent with this presentation?
A. Group A streptococcal pharyngitis B. Viral upper respiratory infection with
pharyngitis C. Pulmonary tuberculosis D. Peritonsillar abscess
Correct Answer: B. Viral upper respiratory infection with pharyngitis
Rationale: Cough, rhinorrhea, and hoarseness commonly suggest a viral cause. These
symptoms make classic group A streptococcal pharyngitis less likely, although
clinical assessment and testing may still be needed depending on the presentation.
Q2. Which symptom in a patient with a sore throat requires the most urgent
assessment?
A. Mild nasal congestion B. Scratchy throat for one day C. Difficulty breathing with
drooling D. Occasional dry cough
Correct Answer: C. Difficulty breathing with drooling
Rationale: Difficulty breathing and drooling may indicate significant upper-airway
obstruction or inability to handle secretions. These are emergency warning signs
requiring immediate assessment and airway-focused care.
Q3. Which finding is most characteristic of group A streptococcal pharyngitis?
, 3
A. Cough and conjunctivitis B. Fever, tonsillar exudates, and tender anterior cervical
lymph nodes C. Chronic painless cough for several months D. Wheezing that
improves with a bronchodilator
Correct Answer: B. Fever, tonsillar exudates, and tender anterior cervical lymph
nodes
Rationale: Fever, tonsillar exudates, tender anterior cervical lymphadenopathy, and
absence of cough support the possibility of streptococcal pharyngitis. They do not
independently confirm the diagnosis.
Q4. Which history finding is particularly relevant when assessing possible pulmonary
tuberculosis (TB)?
A. A single episode of sneezing B. Persistent cough, night sweats, weight loss, and
TB exposure C. A sore throat after shouting D. Mild seasonal itchy eyes
Correct Answer: B. Persistent cough, night sweats, weight loss, and TB exposure
Rationale: Persistent cough, constitutional symptoms, and known exposure raise
concern for active TB. The clinician should assess risk factors, duration of symptoms,
and potential infectiousness.
Q5. A patient reports cough, fever, and shortness of breath. Which initial assessment
is especially important?
A. Hair and nail condition B. Respiratory rate, oxygen saturation, work of breathing,
and vital signs C. Dietary preferences only D. Visual acuity
Correct Answer: B. Respiratory rate, oxygen saturation, work of breathing, and vital
signs
Rationale: These measurements help establish respiratory severity and identify
hypoxemia or respiratory distress. Further evaluation depends on the findings and the
patient’s overall clinical condition.
Q6. Which finding is more suggestive of a lower respiratory tract process than
uncomplicated pharyngitis?
A. Isolated throat discomfort B. Tonsillar redness without respiratory symptoms C.
Crackles on lung auscultation with shortness of breath D. Mild throat irritation after
dry-air exposure
Correct Answer: C. Crackles on lung auscultation with shortness of breath
Rationale: Crackles and dyspnea may indicate pneumonia or another lower respiratory
condition. They warrant assessment beyond an isolated throat infection.
Q7. What is the principal purpose of taking a detailed symptom history in a patient
with respiratory complaints?
