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 are signs and symptoms of a possible kidney transplant rejection in a child? (Select all that apply.)

Correct answer: B

Rationale: Signs of kidney transplant rejection include fever, diminished urinary output, and swelling/tenderness in the graft area. These symptoms indicate that the body may be rejecting the transplanted organ, requiring immediate medical attention.

3. Ongoing fluid losses can overwhelm the child’s ability to compensate, resulting in shock. What early clinical sign precedes shock?

Correct answer: A

Rationale: Tachycardia is an early sign of shock as the body tries to maintain cardiac output in the face of declining circulatory volume. Blood pressure often remains normal until late in the progression, at which point decompensated shock is occurring.

4. How is masturbation in the pre-school child viewed?

Correct answer: C

Rationale: Masturbation in preschool children is a normal behavior as they explore their bodies. It is best viewed as a natural part of development. Parents are often advised to ignore it and provide distractions rather than making the child feel ashamed or embarrassed. Choice A is incorrect because it is a natural behavior and not considered abnormal in this context. Choice B is incorrect as it does not necessarily disrupt the family. Choice D is incorrect as the focus should be on the child's development and well-being, not on the parents' feelings of embarrassment.

5. The nurse is teaching parents about expected language development for their 6-month-old infant. The nurse recognizes the parents understand the teaching if they make which statement?

Correct answer: D

Rationale: At 6 months, infants typically begin to combine syllables like "dada" or "mama," but they do not yet understand the meaning of these words.
