Question 1
What are two pulmonary causes leading to respiratory acidosis?
A. Asthma and shortness of breath
B. Hyperventilation and fever
C. Cystic fibrosis and hypoventilation
D. Anemia and pain
Correct Answer: C. Cystic fibrosis and hypoventilation
Rationale: Respiratory acidosis occurs when carbon dioxide is retained due to
inadequate ventilation. Conditions such as cystic fibrosis impair airway clearance and
gas exchange, while hypoventilation reduces CO₂ elimination, both leading to CO₂
accumulation and acid-base imbalance. Asthma may contribute but is not the best
paired answer here. Hyperventilation causes alkalosis, not acidosis, while anemia and
pain are not primary pulmonary causes.
Question 2
Which issue is commonly seen in a child with Neurobehavioral Disorder Associated
with Prenatal Alcohol Exposure (ND-PAE)?
A. Nearsightedness
B. Trouble planning
C. Frequent nausea
D. Helpfulness
Correct Answer: B. Trouble planning
Rationale: ND-PAE affects executive functioning, especially planning, impulse
control, and decision-making. Prenatal alcohol exposure disrupts brain development.
Visual problems or gastrointestinal symptoms are not core features. Helpfulness is
unrelated to the neurobehavioral deficits caused by the disorder.

Question 3
Which sign is most associated with amyotrophic lateral sclerosis (ALS)?
A. Impaired mental flexibility
B. Blurred vision
C. Head drop
D. Slowed thought processing
Correct Answer: C. Head drop
Rationale: ALS causes progressive degeneration of motor neurons, leading to muscle
weakness, atrophy, and loss of motor control. Neck muscle weakness results in “head
drop,” a classic sign. Cognitive changes may occur but are not primary early features.
Vision changes are not typical.
Question 4
Which drug class can trigger hemolytic anemia?
A. Nitrates
B. Diuretics
C. Cephalosporins
D. CNS stimulants
Correct Answer: C. Cephalosporins
Rationale: Cephalosporins can trigger immune-mediated hemolytic anemia by
promoting antibody destruction of red blood cells. Nitrates, diuretics, and CNS
stimulants are not commonly associated with hemolysis.
Question 5
A patient reports headaches, memory issues, abnormal skin temperature and color
changes, and nocturnal pain. Which condition is most likely?
A. Angina pectoris
B. Atherosclerosis
C. Myocardial infarction
D. Thrombophlebitis
Correct Answer: D. Thrombophlebitis
Rationale: Thrombophlebitis involves inflammation and clot formation in veins, often
causing localized pain, color changes, warmth, and systemic discomfort. The
described vascular inflammation and nocturnal pain align with venous clot pathology
rather than coronary artery disease.

Question 6
Which condition is commonly caused by Adenovirus?
A. Mononucleosis
B. Erythema infection
C. Gastroenteritis
D. Upper respiratory infection
Correct Answer: D. Upper respiratory infection
Rationale: Adenovirus commonly causes respiratory tract infections including
pharyngitis, bronchitis, and upper respiratory tract illness. Gastroenteritis may also
occur, but URTI is the most classic presentation.
Question 7
Classify: Laryngitis, Rhinitis, Pneumonia, COPD, Pharyngitis, Asthma.
A. Upper, Upper, Lower, Lower, Upper, Lower
Correct Answer: Upper respiratory: Laryngitis, Rhinitis, Pharyngitis; Lower
respiratory: Pneumonia, COPD, Asthma
Rationale: Upper respiratory tract infections involve structures above the larynx,
while lower respiratory conditions involve lungs and bronchi. Asthma and COPD
affect lower airways.
Question 8
Which two infections affect the lower respiratory tract?
A. Infectious mononucleosis
B. Respiratory mycoses
C. Acute laryngitis
D. Pulmonary tuberculosis
Correct Answer: B. Respiratory mycoses & D. Pulmonary tuberculosis
Rationale: Both respiratory fungal infections and tuberculosis affect lung parenchyma.
Laryngitis is upper respiratory, and mononucleosis is systemic.
Question 9
Which symptom is associated with systemic lupus erythematosus (SLE)?
