,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 the lungs cannot remove enough CO₂.
Cystic fibrosis causes mucus obstruction and impaired gas exchange, and
hypoventilation leads to CO₂ retention. Asthma can cause respiratory acidosis in severe
cases, but "shortness of breath" is a symptom, not a cause. Hyperventilation causes
respiratory alkalosis, not acidosis. Anemia and pain are not direct pulmonary causes of
respiratory acidosis.
2. Which issue would a child with Neurobehavioral Disorder Associated with
Prenatal Alcohol Exposure (ND-PAE) exhibit?
a. Nearsightedness
b. Trouble planning
c. Frequent nausea
d. Helpfulness
Correct Answer: b. Trouble planning
Rationale: ND-PAE is characterized by neurobehavioral deficits including impaired
executive function, which includes planning, organization, and impulse control.
Nearsightedness, nausea, and helpfulness are not characteristic of this disorder.
3. Which sign is 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 is a progressive neurodegenerative disease affecting motor neurons,
leading to muscle weakness and atrophy. "Head drop" (dropped head syndrome) occurs
due to weakness of the neck extensor muscles. Cognitive changes can occur but are not
classic signs. Blurred vision is not typical.
4. Which classification of drugs can trigger hemolytic anemia?
a. Nitrates
b. Diuretics
c. Cephalosporins
d. CNS stimulants
Correct Answer: c. Cephalosporins
Rationale: Cephalosporins are known to cause drug-induced immune hemolytic
anemia. Nitrates, diuretics, and CNS stimulants are not classically associated with
hemolytic anemia.
5. A patient records documents headaches with memory defects. The patient's
color and temperature are unusual, and the patient reports pain at night. Which
condition is described?
a. Angina pectoris
b. Atherosclerosis
c. Myocardial infarction
d. Thrombophlebitis
Correct Answer: d. Thrombophlebitis
Rationale: Thrombophlebitis involves inflammation and clot formation in veins, often
presenting with pain, warmth, redness, and swelling. Night pain and unusual
, color/temperature changes are consistent with venous insufficiency. Angina and MI
present with chest pain; atherosclerosis is often asymptomatic until complications arise.
6. Which condition is caused by Adenovirus?
a. Mononucleosis
b. Erythema infectiosum
c. Gastroenteritis
d. Upper respiratory infection
Correct Answer: d. Upper respiratory infection
Rationale: Adenoviruses commonly cause upper respiratory tract infections, including
the common cold, pharyngitis, and conjunctivitis. Mononucleosis is caused by Epstein-
Barr virus; erythema infectiosum by parvovirus B19; gastroenteritis by rotavirus or
norovirus.
7. Classify each condition as either an upper tract infection or a lower tract
infection.
Laryngitis – Upper
Rhinitis – Upper
Pneumonia – Lower
COPD – Lower
Pharyngitis – Upper
Asthma – Lower
Correct Answers:
Laryngitis – Upper
Rhinitis – Upper
Pharyngitis – Upper
Pneumonia – Lower
COPD – Lower
Asthma – Lower
