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. A child diagnosed with aplastic anemia is admitted to the hospital. The parents ask the nurse what aplastic anemia is. Which response by the nurse is accurate?

• A. Aplastic anemia causes a proliferation of white blood cells.
• B. Aplastic anemia is characterized by abnormally shaped red blood cells.
• C. Aplastic anemia is caused by the bone marrow producing inadequate cells.
• D. Aplastic anemia is a disorder that occurs after a viral illness.

Correct answer: C

Rationale: Aplastic anemia is a condition where the bone marrow fails to produce sufficient red blood cells, white blood cells, and platelets, leading to pancytopenia. This can result in fatigue, infections, and bleeding tendencies. It is not characterized by abnormal red blood cell shapes, but rather by a reduction in the production of blood cells. Therefore, the accurate response is that aplastic anemia is caused by the bone marrow producing inadequate cells. Choices A and B are incorrect as aplastic anemia does not cause a proliferation of white blood cells or involve abnormally shaped red blood cells. Choice D is incorrect as aplastic anemia is not typically a disorder that occurs after a viral illness.

3. A father calls the clinic because he found his young daughter squirting Visine eyedrops into her mouth. What is the most appropriate nursing action?

• A. Reassure the father that Visine is harmless.
• B. Direct him to seek immediate medical treatment.
• C. Recommend inducing vomiting with ipecac.
• D. Advise him to dilute Visine by giving his daughter several glasses of water to drink.

Correct answer: B

Rationale: Visine is not harmless when ingested, and immediate medical treatment is necessary due to the risk of toxicity. Vomiting should not be induced without medical advice, and dilution with water is not an appropriate treatment.

4. The parent of an 8.2-kg (18-lb) 9-month-old infant is borrowing a federally approved car seat from the clinic. The nurse should explain that the safest way to put in the car seat is what?

• A. Front facing in back seat
• B. Rear facing in back seat
• C. Front facing in front seat with air bag on passenger side
• D. Rear facing in front seat if an air bag is on the passenger side

Correct answer: B

Rationale: Infants should be placed rear-facing in the back seat until they are at least 2 years old or exceed the weight/height limit of their car seat for optimal safety.

5. What term is appropriate terminology to use for an infant whose intrauterine growth rate was slowed and whose birth weight falls below the 10th percentile on intrauterine growth charts?

• A. Postterm
• B. Postmature
• C. Low birth weight
• D. Small for gestational age

Correct answer: D

Rationale: The correct answer is D, 'Small for gestational age.' A small for gestational age, or small-for-date, infant is any child whose intrauterine growth rate was slowed and whose birth weight falls below the 10th percentile on intrauterine growth curves. Choices A and B, 'Postterm' and 'Postmature,' refer to infants born after 42 weeks of gestational age regardless of birth weight, and do not specifically address growth rate. Choice C, 'Low birth weight,' refers to infants with a birth weight less than 2500 g (5.5 pounds) regardless of gestational age, which is a different classification compared to being small for gestational age.
