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. What is a physical characteristic of infants whose mothers smoked during pregnancy?

• A. Being large for gestational age
• B. Growth restriction in weight only
• C. Preterm but size appropriate for gestational age
• D. Growth restriction in weight, length, and chest and head circumference

Correct answer: D

Rationale: The correct answer is D: Growth restriction in weight, length, and chest and head circumference. Infants born to mothers who smoke during pregnancy exhibit growth failure in weight, length, chest, and head circumference. This growth failure is directly related to the number of cigarettes smoked by the mother. Choices A, B, and C are incorrect because infants exposed to maternal smoking do not tend to be large for gestational age, experience growth restriction in weight only, or be preterm but size appropriate for gestational age.

3. The school nurse is teaching a group of adolescents about avoiding contaminated water during a mission trip. What should the nurse include in the teaching?

• A. Ice
• B. All are applicable
• C. Raw vegetables
• D. Unpeeled fruits

Correct answer: B

Rationale: The correct answer is B: All are applicable. Ice, raw vegetables, and unpeeled fruits can be sources of contamination in areas where water purity is questionable. It's safer to avoid these during a mission trip to prevent waterborne illnesses. Choice A (Ice), C (Raw vegetables), and D (Unpeeled fruits) are all potential sources of contamination in areas with questionable water quality. Including all these items in the teaching will help adolescents make informed decisions to stay healthy during their mission trip.

4. The clinic nurse is assessing a child with a heavy ascariasis lumbricoides (common roundworm) infection. Which assessment findings should the nurse expect?

• A. Anemia
• B. Anorexia
• C. All are applicable
• D. Intestinal colic

Correct answer: D

Rationale: A heavy roundworm infection can cause anemia, anorexia, irritability, and an enlarged abdomen due to the worms’ effects on nutrient absorption and intestinal 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.
