RN Nursing Care of Children Online Practice 2019 A

Correct Answer: A

Rationale: The correct answer is A: Transition from fetal to neonatal breathing. The onset of breathing is the most immediate and critical physiologic change required for the transition to extrauterine life. Factors that interfere with this normal transition increase fetal asphyxia, which is a condition of hypoxemia, hypercapnia, and acidosis. While body temperature maintenance, stabilization of fluid and electrolytes, and closure of fetal shunts in the heart are crucial changes in the transition to extrauterine life, breathing and the exchange of oxygen for carbon dioxide must take precedence as they are essential for newborn survival.

Correct Answer: C

Rationale: A high reticulocyte count indicates that the bone marrow is producing more red blood cells, which is a sign of recovery from anemia as the body replenishes its iron stores and increases hemoglobin levels. Low hemoglobin (Choice A) would indicate ongoing anemia rather than improvement. A normal platelet count (Choice B) and low hematocrit (Choice D) are not specific indicators of improvement in iron deficiency anemia.

Correct Answer: D

Rationale: N-acetylcysteine is the specific antidote for acetaminophen poisoning, working by replenishing glutathione and preventing liver damage. The other options are antidotes for different types of poisoning (e.g., Fomepizole for methanol or ethylene glycol poisoning).

Correct Answer: C

Rationale: The correct response is to let the parents know they are allowed to stay with the child. Allowing parents to stay with the child can help reduce the child's anxiety and provide comfort. Choice A is incorrect as the parents should be encouraged to stay with their child. Choice B is not the immediate response the nurse should provide. Choice D is inappropriate as it does not address the benefits and importance of parental presence for the child's well-being during hospitalization.

Correct Answer: D

Rationale: These behaviors are consistent with FTT and indicate social withdrawal, which is often observed in infants who are not thriving. A wide-eyed gaze and avoidance of eye contact can also indicate developmental delays or emotional disturbances.
