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

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. What type of shock is characterized by a hypersensitivity reaction causing massive vasodilation and capillary leaks, which may occur with drug or latex allergy?

Correct answer: D

Rationale: Anaphylactic shock is a severe allergic reaction that causes massive vasodilation and increased capillary permeability, leading to rapid fluid shifts and circulatory collapse if not treated promptly. Neurogenic, cardiogenic, and hypovolemic shocks have different etiologies.

3. What tool would be most useful to assess maternal and newborn attachment behaviors?

Correct answer: C

Rationale: The NCAST Feeding Scale is the most suitable tool to evaluate maternal and newborn attachment behaviors during feedings. It focuses on observing the interaction between the parent and infant, providing insights into their bonding. The Apgar score is used to assess a neonate's immediate transition to life outside the womb, not specifically maternal and newborn attachment behaviors. The Ballard scale is used to estimate gestational age, not to assess attachment behaviors. The Brazelton Neonatal Behavioral Assessment Scale is designed to evaluate a newborn's responses to various stimuli, not specifically maternal and newborn attachment behaviors.

4. The nurse is interviewing the mother of an infant. The mother reports, "I had a difficult delivery, and my baby was born prematurely." This information should be recorded under which heading?

Correct answer: A

Rationale: The history section of the health record includes details about pregnancy, labor, and delivery, as these factors can have significant implications for the child's health.

5. What is the best age to introduce solid food into an infant’s diet?

Correct answer: B

Rationale: The introduction of solid foods is recommended at 4 to 6 months when the infant's digestive system is more developed and ready for solids.
