RN Nursing Care of Children Online Practice 2019 A

Correct Answer: A

Rationale: The correct answer is A. A child is expected to double their birth weight by 6 months. This is a common guideline used to monitor healthy growth and development in infants. Choices B, C, and D are incorrect as they do not provide the expected weight based on the given information.

Correct Answer: D

Rationale: The correct answer is D. Pain is frequently reported by children with cancer, with around 84% experiencing it. Most children report moderate to severe pain, with about half finding it highly distressing. There is no evidence to suggest that children often misrepresent their pain experiences. Pain tolerance is not solely based on age but is a complex phenomenon. Children do not become accustomed to painful procedures, as each experience of pain is unique.

Correct Answer: B

Rationale: The NCHS growth charts serve as reference guides for all racial or ethnic groups, including African American children. The 20th percentile for height and weight does not indicate nutritional failure but provides a reference point for ongoing assessment. Choice A is incorrect because being at the 20th percentile does not automatically imply the need for nutritional intervention. Choice C is incorrect as there is no correction factor specifically used for nonwhite ethnic groups in this context. Choice D is incorrect as a single measurement at the 20th percentile can provide valuable information for assessment.

Correct Answer: C

Rationale: Testicular torsion is a surgical emergency requiring immediate medical evaluation. Applying heat or elevating the legs will not alleviate the torsion, and delaying care can lead to testicular necrosis.

Correct Answer: C

Rationale: Malformed or low-set ears are often associated with congenital urinary tract anomalies, as both the ears and kidneys develop around the same time during fetal growth. Myelomeningocele, cardiovascular anomalies, and lower extremity defects are less commonly associated with UT anomalies.
