Nursing Care of Children ATI

Correct Answer: C

Rationale: The correct answer is C. According to Erikson, the primary task of a preschool-aged child is to explore and assert control over their environment. This behavior is demonstrated by the child opening drawers, pulling out supplies, and examining them, showcasing curiosity and exploration. Choices A, B, and D do not align with the primary developmental task of a preschool-age child according to Erikson. Reading a book and singing a song are more passive activities, while roughhousing with the parent does not directly relate to exploration and asserting control over the environment.

Correct Answer: B

Rationale: The finger-to-nose test assesses cerebellar function, which is responsible for balance and coordination. The test evaluates how well the cerebellum controls motor functions and coordination. Choice A, deep tendon reflexes, is incorrect because this test does not assess reflexes but rather cerebellar function. Choice C, sensory discrimination, is incorrect as this test focuses on motor function rather than sensory abilities. Choice D, ability to follow directions, is incorrect since the test primarily assesses motor coordination and not cognitive skills related to following instructions.

Correct Answer: A

Rationale: To calculate the dosage, multiply the child's weight (10 kg) by the dosage (8 mg/kg) which equals 80 mg. Since the concentration is 100 mg/5 mL, to find out how much to administer, you need to determine how many 5 mL doses are in 80 mg. It will be 80 mg � 100 mg * 5 mL = 4 mL. Therefore, the correct answer is 4 mL. Choice B, 2 mL, is incorrect because it does not account for the correct dosage calculation. Choice C, 5 mL, is incorrect as it does not consider the dosage based on the child's weight. Choice D, 3 mL, is incorrect as it does not reflect the accurate dosage calculation.

Correct Answer: D

Rationale: In newborns, intramuscular vitamin K is traditionally administered into the vastus lateralis muscle. This site is preferred due to its large muscle mass and accessibility. The dorsogluteal site is not recommended for newborns due to the risk of injury to the sciatic nerve. The deltoid site is also not recommended for newborns. The rectus femoris muscle is not commonly used for intramuscular injections in newborns.

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.
