HCR 240 FINAL ACTUAL EXAM
Practice Questions & Verified Answers With Rationale
NEW EXAM BANK
GRADED A+
This comprehensive practice examination is designed to prepare students for the HCR 240
(Pathophysiology and Pharmacology) Final Exam. The exam covers essential knowledge areas
including respiratory system pathophysiology, cardiovascular system, neurological disorders,
endocrine disorders, infectious diseases, oncology, hematology, renal and urinary disorders,
gastrointestinal disorders, and pharmacological interventions. The 250 questions in this test
bank reflect the core competencies required for success in the HCR 240 final examination,
including understanding of disease processes, diagnostic criteria, clinical manifestations, and
evidence-based treatment approaches.

,1. A patient asks the nurse why they need to wear oxygen in the hospital and how it
works with blood cells. Which is the best response?
A. Blood cells passing through the arteries in the lungs are oxygenated and then carry
oxygen to the body
B. When you take in a breath, the blood cells in your nose takes in the oxygen
C. The blood that pumps through the heart takes in oxygen
D. The blood receives oxygen from the bone marrow and carries it to the tissues
Correct Answer: A
Rationale: Blood cells passing through the arteries in the lungs are oxygenated and then
carry oxygen to the body.
2. How does severe hypoxia develop with pneumonia?
A. Inflammatory exudate absorbs oxygen from the alveolar air
B. Infection reduces effective compensation by the heart
C. Acidosis depresses respirations
D. Oxygen diffusion is impaired by the congestion
Correct Answer: D
Rationale: Oxygen diffusion is impaired by the congestion in pneumonia.
3. The nurse is discussing with the student nurse a pulse oxygenation measurement. The
student nurse knows what measurement is acceptable for a pulse oxygenation reading in
a healthy adult?
A. 92-95%
B. 89-92%
C. 97-100%
D. 90-93%
Correct Answer: C
Rationale: 97-100% is the normal pulse oximetry range for a healthy adult.
4. What causes the expanded anteroposterior (A-P) thoracic diameter (barrel chest) in
patients with emphysema?
A. Persistent coughing to remove mucus
B. Recurrent damage to lung tissues
C. Dilated bronchi and increased mucus secretions
D. Air trapping and hyperinflation
Correct Answer: D
Rationale: Air trapping and hyperinflation cause barrel chest in emphysema.
5. What is an early sign of lung cancer?
, A. Weight loss
B. Chronic cough
C. Air trapping and over inflation of the lung
D. Bone pain
Correct Answer: B
Rationale: Chronic cough is often an early sign of lung cancer.
6. Which of the following describes lobar pneumonia?
A. Sudden onset fever and chills with crackles and rusty sputum
B. Insidious onset, diffuse interstitial infection
C. Opportunistic bacteria causing low-grade fever with cough and thick greenish sputum
D. Viral infection causing nonproductive cough and pleuric pain
Correct Answer: A
Rationale: Lobar pneumonia presents with sudden onset fever, chills, crackles, and rusty
sputum.
7. One of the functions of the pulmonary system is the:
A. Principle mechanism for cooling the heart
B. Exchange of gases between the environment and blood
C. Movement of blood into and out of the capillaries
D. Expelling of bacteria
Correct Answer: B
Rationale: The pulmonary system is responsible for gas exchange between the
environment and blood.
8. What is the primary cause of hypoxemia in acute respiratory distress syndrome
(ARDS)?
A. Decreased cardiac output
B. Shunting of blood through non-ventilated alveoli
C. Increased oxygen consumption
D. Decreased hemoglobin
Correct Answer: B
Rationale: Shunting of blood through non-ventilated alveoli causes hypoxemia in ARDS.
9. What is the pathophysiology of asthma?
A. Destruction of alveolar walls
B. Chronic inflammation and airway hyperresponsiveness
C. Thickening of the bronchial smooth muscle
D. Pulmonary fibrosis
, Correct Answer: B
Rationale: Asthma involves chronic inflammation and airway hyperresponsiveness.
10. What is the characteristic finding in chronic bronchitis?
A. Air trapping and hyperinflation
B. Productive cough with sputum for at least 3 months in 2 consecutive years
C. Destruction of alveolar walls
D. Restrictive lung disease
Correct Answer: B
Rationale: Chronic bronchitis is defined by a productive cough for 3 months in 2
consecutive years.
11. What is the primary cause of pulmonary embolism?
A. Fat embolism from long bone fractures
B. Air embolism from IV lines
C. Deep vein thrombosis (DVT) from the lower extremities
D. Amniotic fluid embolism
Correct Answer: C
Rationale: Pulmonary emboli most commonly arise from DVTs in the lower extremities.
12. What is the triad of symptoms in pulmonary embolism?
A. Chest pain, hemoptysis, fever
B. Sudden dyspnea, chest pain, and hemoptysis
C. Cough, fever, and crackles
D. Wheezing, dyspnea, and cough
Correct Answer: B
Rationale: The classic triad is sudden dyspnea, chest pain, and hemoptysis.
13. What is the pathophysiology of tuberculosis?
A. Mycobacterial infection causing granuloma formation
B. Viral infection causing alveolar damage
C. Fungal infection causing cavitation
D. Bacterial infection causing acute inflammation
Correct Answer: A
Rationale: Tuberculosis is caused by Mycobacterium tuberculosis, leading to granuloma
formation.
14. What is the most common type of lung cancer?
A. Small cell lung cancer
