1. The nurse's approach when introducing hospital equipment to a preschooler who seems afraid should be based on which principle?

Correct answer: A

Rationale: Preschoolers may engage in magical thinking and believe inanimate objects are alive, so the nurse should explain the equipment in a way that reduces fear.

2. Which term best describes the sharing of common characteristics that differentiate one group from other groups in a society?

Correct answer: C

Rationale: Ethnicity refers to the shared characteristics such as nationality, culture, language, and beliefs that differentiate one group from another.

3. When checking the intravenous (IV) site on a child, the nurse should take which action?

Correct answer: C

Rationale: Looking at and palpating the IV site helps assess for signs of infiltration or infection, such as swelling, redness, or pain. Simply looking or asking the child may miss subtle signs, and removing all the tape unnecessarily disrupts the site.

4. One of the most critical needs of the infant is control of body temperature. The nurse caring for a newborn warms all equipment that comes in direct contact with the newborn to help prevent which type of heat loss?

Correct answer: C

Rationale: The correct answer is Conduction (choice C). Conduction heat loss occurs when the newborn’s skin comes into direct contact with a cooler surface, so warming equipment helps prevent this. Choice A, Convection, is the transfer of heat through air or water currents, not direct contact. Choice B, Evaporation, is the loss of heat through moisture on the skin evaporating, not direct contact. Choice D, Radiation, is the transfer of heat in the form of waves or particles, not direct contact.

5. What is the most common cause of acute kidney injury in children?

Correct answer: C

Rationale: Hemolytic uremic syndrome is the most common cause of acute kidney injury in children. While dehydration can lead to prerenal acute kidney injury, it is not the most common cause in children. Glomerulonephritis is a common cause of chronic kidney disease but not typically the most common cause of acute kidney injury in children. Sepsis can lead to acute kidney injury, but in children, hemolytic uremic syndrome is more prevalent.
