Nursing Elites

1. 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.

2. The nurse is teaching parents of a child with gastroesophageal reflux (GER) disease about foods that can exacerbate acid reflux. What foods should be included in the teaching session?

• A. Citrus
• B. All of the above
• C. Spicy foods
• D. Peppermint

Correct answer: B

Rationale: The correct answer is B: All of the above. Citrus, spicy foods, and peppermint are known to exacerbate GER symptoms by increasing acid production or relaxing the lower esophageal sphincter. Therefore, these foods should be avoided by a child with GER disease. Bananas, on the other hand, are generally safe and do not contribute to acid reflux. Choice B is correct because all the mentioned foods can worsen GER symptoms, while bananas are considered safe.

3. 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.

4. Which assessment findings should the nurse expect in a child with sickle cell anemia experiencing an acute vaso-occlusive crisis?

• A. Circulatory collapse, hypovolemia
• B. Cardiomegaly, systolic murmur
• C. Hepatomegaly, intrahepatic cholestasis
• D. Painful swelling of joints in hands and feet, tissue engorgement

Correct answer: D

Rationale: The correct answer is D. Vaso-occlusive crises in sickle cell anemia are characterized by painful swelling of the joints in the hands and feet (hand-foot syndrome) and tissue engorgement due to the obstruction of blood flow by sickled cells. Choices A, B, and C are incorrect because circulatory collapse, hypovolemia, cardiomegaly, systolic murmur, hepatomegaly, and intrahepatic cholestasis are not typically associated with an acute vaso-occlusive crisis in sickle cell anemia.

5. At which age should the nurse expect an infant to begin smiling in response to pleasurable stimuli?

• A. 1 month
• B. 2 months
• C. 3 months
• D. 4 months

Correct answer: B

Rationale: Infants typically begin to smile in response to pleasurable stimuli by 2 months, which is an early sign of social interaction and emotional development.
