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. A four-year-old boy is admitted to the hospital with leg pain and fever. He is pale-looking and has bruises over various areas of his body. The physician suspects acute lymphoblastic leukemia (ALL). Which test would be used to confirm the diagnosis?

Correct answer: A

Rationale: A bone marrow aspirate is the definitive test to confirm acute lymphoblastic leukemia (ALL) in this case. It allows for the examination of leukemic cells in the bone marrow, providing a direct assessment of the disease. Red blood cell count (Choice B) is not specific for diagnosing leukemia but may show anemia commonly seen in leukemia patients. Lumbar puncture (Choice C) is used to assess central nervous system involvement, not primarily for confirming ALL. Bone scan (Choice D) is not a standard diagnostic test for ALL and is mainly used for evaluating bone metastases in other conditions.

3. You are developing a plan of care for a hospitalized child. Which age group is most likely to view illness as a punishment for misdeeds?

Correct answer: B

Rationale: Preschool-aged children often engage in magical thinking, where they may believe that illness is a punishment for misdeeds. This belief is related to their cognitive development stage, where they may attribute cause and effect in a magical or unrealistic way. Adolescents are more likely to view illness as a disruption to their sense of independence or control. Infants lack the cognitive development to associate illness with punishment for misdeeds. School-aged children typically have a more concrete understanding of illness and its causes, moving away from magical thinking.

4. The nurse is caring for a child with an order of Ampicillin 250 mg IV in 30 mL of Normal Saline to infuse over 30 minutes. How many mL/hour should the nurse set the pump?

Correct answer: A

Rationale: The correct setting for the infusion pump should be 60 mL/hour to deliver 30 mL in 30 minutes. To calculate the infusion rate in mL/hour, divide the total volume to be infused (30 mL) by the total time for infusion (30 minutes) and then multiply by 60 to convert minutes to hours. Therefore, 30 mL / 30 minutes * 60 minutes/hour = 60 mL/hour. Choices B, C, and D are incorrect because they do not match the calculation based on the given parameters.

5. Which intervention is the most appropriate recommendation for relief of teething pain?

Correct answer: C

Rationale: A frozen teething ring is effective for relieving teething pain as the cold helps numb the gums and reduce inflammation, making it a safe and effective method for managing discomfort
