RECENT]2025/2026
1. A patient with a major burn injury presents with black-colored
sputum. What does this most likely indicate?
• A) Carbon monoxide poisoning
• B) Inhalation injury with particulate matter
• C) Pulmonary edema
• D) Pneumonia
• Correct Answer: B
• Rationale: Black-colored sputum in a burn patient is a classic sign
of an inhalation injury, where soot and particulate matter from
smoke/combustion are deposited in the airway. Carbon monoxide
poisoning is associated with cherry-red skin, while pink, frothy
sputum suggests pulmonary edema.
2. Which pathophysiological mechanism is MOST responsible for the
development of type 1 diabetes mellitus?
• A) Insulin resistance in peripheral tissues
• B) Autoimmune destruction of pancreatic beta cells
• C) Excessive glucagon production
• D) Hepatic overproduction of glucose
• Correct Answer: B
• Rationale: Type 1 diabetes is an autoimmune disease where the
body's immune system (T-cells) destroys the insulin-producing
beta cells in the pancreas, leading to an absolute insulin deficiency.
Insulin resistance is the hallmark of type 2 diabetes.
,3. A patient presents with metabolic acidosis (pH 7.25, HCO3 15
mEq/L). Which compensation mechanism is expected?
• A) Increased respiratory rate (Kussmaul respirations)
• B) Decreased respiratory rate
• C) Increased bicarbonate retention
• D) Decreased renal acid excretion
• Correct Answer: A
• Rationale: The body compensates for metabolic acidosis by
hyperventilating (Kussmaul respirations) to "blow off" CO2, which
helps raise the blood pH back toward normal. Renal compensation
(retaining bicarbonate) is a slower, secondary response.
4. Which condition is the MOST common cause of viral sinus
infections?
• A) Streptococcus pneumoniae
• B) Common cold virus (rhinovirus) or influenza virus
• C) Haemophilus influenzae
• D) Staphylococcus aureus
• Correct Answer: B
• Rationale: The vast majority (about 90%) of sinus infections are
caused by viruses, most commonly the rhinovirus or influenza
virus. Bacteria like Streptococcus pneumoniae and Haemophilus
influenzae are responsible for only a small percentage of cases.
5. A patient with a major burn injury presents with black-colored
sputum. What does this most likely indicate?
• This is a duplicate of Question 1.
• Correct Answer: B
6. A patient develops a severe infection following a surgical
procedure due to contamination during the operation. This would
be classified as which type of disease?
• A) Idiopathic
• B) Nosocomial
• C) Iatrogenic
, • D) Communicable
• Correct Answer: C
• Rationale: An iatrogenic disease is one that is directly caused by a
medical procedure or intervention. While a hospital-acquired
infection is nosocomial, an infection resulting directly from a
surgical procedure is considered iatrogenic.
7. A patient is prescribed a daily low-dose aspirin (81 mg) to prevent
a myocardial infarction. This is an example of:
• A) Treatment
• B) Prophylaxis
• C) Secondary prevention
• D) Palliative care
• Correct Answer: B
• Rationale: Prophylaxis refers to a measure taken to prevent the
occurrence of a disease. Taking a daily low-dose aspirin to prevent
a heart attack in a high-risk patient is a classic example of
prophylactic treatment.
8. The sequence of events involved in the tissue changes related to a
specific disease process is called:
• A) Etiology
• B) Pathogenesis
• C) Morphology
• D) Epidemiology
• Correct Answer: B
• Rationale: Pathogenesis is the term used to describe the
development and evolution of a disease, or the sequence of events
that lead to the tissue changes characteristic of a specific disease
process.
9. A disease that GRADUALLY develops with only VAGUE or very
mild signs is described as:
• A) Acute
• B) Chronic
• C) Insidious
, • D) Latent
• Correct Answer: C
• Rationale: An insidious disease has a gradual onset with mild,
non-specific, or vague symptoms that often go unnoticed initially.
Hepatitis is a common example.
10. Which of the following best describes an ACUTE disease?
• A) Milder symptoms that develop gradually with intermittent acute
episodes
• B) Sudden onset with short-term symptoms such as high fever and
severe pain
• C) A "silent" stage with no clinical signs
• D) A period when disease manifestations subside
• Correct Answer: B
• Rationale: An acute disease is characterized by a sudden onset
and short-term, often severe, symptoms. Appendicitis is a classic
example.
11. A patient with rheumatoid arthritis experiences a flare-up with
increased joint pain and swelling. This is best described as:
• A) Remission
• B) Exacerbation
• C) Sequelae
• D) Complication
• Correct Answer: B
• Rationale: An exacerbation is a period of worsening symptoms in
a chronic disease. In rheumatoid arthritis, these periods are also
known as "flares."
12. A patient with multiple sclerosis has been symptom-free for 6
months. This period is called:
• A) Exacerbation
• B) Remission
• C) Subclinical state
• D) Convalescent period
• Correct Answer: B
