RN Nursing Care of Children Online Practice 2019 A

Correct Answer: A

Rationale: The American Academy of Pediatrics advocates for exclusive breastfeeding until 1 year of age as the best form of infant nutrition. Breastfeeding for the first year of life provides optimal nutrition and benefits for the infant. Exclusive breastfeeding until 6 months of age is not in line with the AAP's recommendation for a full year. While commercially prepared infant formula is an alternative if breastfeeding is not possible, it is not the preferred choice according to AAP guidelines. The recommendation for commercial infant formula until 1 year of age is not in line with the AAP's stance on the benefits of extended breastfeeding.

Correct Answer: D

Rationale: The correct answer is D: Growth restriction in weight, length, and chest and head circumference. Infants born to mothers who smoke during pregnancy exhibit growth failure in weight, length, chest, and head circumference. This growth failure is directly related to the number of cigarettes smoked by the mother. Choices A, B, and C are incorrect because infants exposed to maternal smoking do not tend to be large for gestational age, experience growth restriction in weight only, or be preterm but size appropriate for gestational age.

Correct Answer: A

Rationale: The correct answer is A: Neuroblastoma. Neuroblastoma, a cancer that arises from nerve tissue, is associated with increased levels of catecholamine metabolites, including VMA and HVA, in the urine. Nephroblastoma (Wilms tumor) is a type of kidney cancer and is not typically associated with elevated levels of catecholamine breakdown products. Leukemia is a cancer of the blood and bone marrow and does not lead to increased VMA and HVA excretion in urine. Osteosarcoma is a bone cancer and is not linked to elevated levels of catecholamine metabolites in the urine.

Correct Answer: C

Rationale: Withdrawing and discarding a sample equal to the amount of fluid in the device ensures that the blood drawn is not diluted by the IV fluids, providing accurate lab results.

Correct Answer: A

Rationale: Picking up a pencil requires the use of the pincer grasp, which involves the coordination of the thumb and forefinger to hold small objects. The pincer grasp is a fine motor skill essential for tasks that necessitate precision and dexterity. Choices B, C, and D are incorrect. Prehension refers to the act of grasping or holding an object, parachute reflex is a protective response to sudden movement or loss of support, and grasp reflex is an automatic closing of the hand when an object is placed in the palm, none of which specifically relate to the action of picking up a pencil.
