1. A major reason for the development of respiratory distress syndrome in the preterm infant is:

• A. Excessive surfactant
• B. Lack of surfactant
• C. Immature immune system
• D. Lack of body fat

Correct answer: B

Rationale: The correct answer is B: Lack of surfactant. Respiratory distress syndrome (RDS) in preterm infants is primarily due to a lack of surfactant, which is crucial for keeping the lungs inflated. Without adequate surfactant, the alveoli collapse, leading to breathing difficulties. Choice A, Excessive surfactant, is incorrect as RDS is caused by an insufficient amount of surfactant. Choice C, Immature immune system, and Choice D, Lack of body fat, are not directly related to the development of respiratory distress syndrome in preterm infants.

2. Which is an accurate description of homosexual (or gay-lesbian) families?

• A. A nurturing environment is lacking.
• B. The children become homosexual like their parents.
• C. The stability needed to raise healthy children is lacking.
• D. The quality of parenting is equivalent to that of nongay parents.

Correct answer: D

Rationale: Research shows that the quality of parenting in homosexual families is equivalent to that in heterosexual families, and children thrive in nurturing environments provided by same-sex parents.

3. What is a clinical manifestation of acetaminophen poisoning?

• A. Hyperpyrexia
• B. Hepatic involvement
• C. Severe burning pain in stomach
• D. Drooling and inability to clear secretions

Correct answer: B

Rationale: Acetaminophen poisoning primarily affects the liver, leading to hepatic involvement, which may present as jaundice, liver failure, or elevated liver enzymes. Hyperpyrexia, severe pain, and drooling are more associated with other types of poisoning.

4. What pathologic process is believed to be responsible for the development of postinfectious glomerulonephritis?

• A. Infarction of renal vessels
• B. Immune complex formation and glomerular deposition
• C. Bacterial endotoxin deposition on and destruction of glomeruli
• D. Embolization of glomeruli by bacteria and fibrin from endocardial vegetation

Correct answer: B

Rationale: Postinfectious glomerulonephritis is typically caused by immune complex deposition in the glomeruli following a streptococcal infection. This immune response leads to inflammation and impaired kidney function.

5. Chemicals, agents, or factors that cause physical defects in the developing embryo and are most harmful during organogenesis are:

• A. Teratogens
• B. Heterozygous
• C. Inborn errors
• D. Multifactorial

Correct answer: A

Rationale: Teratogens are substances that can cause congenital abnormalities, especially during the first trimester when organogenesis occurs. Choice A, Teratogens, is the correct answer as it specifically refers to substances that cause physical defects in the developing embryo. Choices B, Heterozygous, C, Inborn errors, and D, Multifactorial, are incorrect as they do not directly relate to substances that cause physical defects in embryos during organogenesis.
