1. Why are neonates predisposed to problems with thermoregulation?

Correct answer: C

Rationale: Neonates have a large surface area relative to their weight, which makes them prone to heat loss to the environment, leading to thermoregulation issues. The underdeveloped kidney affecting urine concentration (Choice A) is unrelated to the thermal regulation process. While a flexed posture can help retain heat (Choice B), it does not outweigh the impact of the large body surface area in neonates. Although subcutaneous fat (Choice D) provides insulation, in neonates, the large body surface area is more significant in contributing to heat loss than the fat's insulating properties.

2. What is an advantage of the ventrogluteal muscle as an injection site in young children?

Correct answer: B

Rationale: The ventrogluteal site is free of significant nerves and vascular structures, making it a safer choice for intramuscular injections in young children compared to other sites that may be more prone to complications.

3. An eleven-year-old boy is admitted with a history of type 1 diabetes. What information about school age should the nurse use to formulate the teaching plan for daily injections?

Correct answer: B

Rationale: By the age of eleven, many children are capable of administering their own insulin injections with supervision, fostering independence and better management of their diabetes. This age is appropriate for the child to take on more responsibility for their care. While parental involvement is still crucial for supervision and guidance, the child can start to learn and perform the injections themselves. Choice A is incorrect because parental involvement is important for safety and proper technique. Choice C is incorrect as waiting until closer to adolescence may delay the child's ability to manage their diabetes effectively. Choice D is incorrect as reaching injection sites is not the sole criteria; proper technique and supervision are essential.

4. The parent of a 3-month-old infant is concerned because the infant is not able to sit independently. How should the nurse respond to this parent's concern?

Correct answer: D

Rationale: The correct answer is D because sitting steadily typically occurs closer to 6-8 months of age, not 3 or 4 months. Choice A is incorrect because sitting ability and the age of first tooth eruption are not related. Choice B and C are incorrect as most infants do not sit steadily at 3 or 4 months, and it is more common for infants to achieve this milestone around 6-8 months.

5. The nurse is preparing to administer a measles, mumps, rubella, and varicella (MMRV) vaccine. Which is a contraindication associated with administering this vaccine?

Correct answer: D

Rationale: A compromised immune system is a contraindication for the MMRV vaccine because it is a live attenuated vaccine and could potentially cause an infection in an immunocompromised child.
