ATI Pediatrics Proctored Exam 2023 with NGN

Correct Answer: B

Rationale: The correct answer is B. Vitamin K is administered to newborns to prevent bleeding disorders since they have low levels of vitamin K, which is essential for blood clotting. By providing this injection, the nurse ensures that the newborn has an adequate supply of vitamin K to support proper blood clotting and prevent potential bleeding complications. Choices A, C, and D are incorrect because vitamin K's primary role in newborns is related to blood clotting and preventing bleeding, not liver function, immune system, or growth and development.

Correct Answer: B

Rationale: A heart rate of 80 bpm is least likely to be observed in a normal newborn. The normal heart rate range for a newborn is usually higher than 80 bpm, typically ranging from 120-160 bpm. The Moro reflex (choice A) is a normal newborn reflex, respirations being irregular (choice C) are expected due to the immature respiratory control center, and an uneven head shape (choice D) is common due to molding during vaginal delivery.

Correct Answer: C

Rationale: Warfarin is a medication commonly used as a blood thinner to prevent blood clot formation. It works by inhibiting the clotting factors in the blood, thereby reducing the risk of clot formation and helping in the management of conditions like congestive heart failure and arrhythmias. Choices A, B, and D are antibiotics and do not have blood-thinning properties like Warfarin.

Correct Answer: A

Rationale: Initiating breastfeeding within the first half-hour after birth is crucial for successful breastfeeding and bonding, as recommended by the World Health Organization. This early initiation helps establish breastfeeding and supports the newborn's health by providing colostrum, the nutrient-rich first milk. Choice B, 'After the newborn's first bath,' is incorrect because initiating breastfeeding should not be delayed after birth. Choice C, 'When the newborn begins to cry,' is incorrect as it does not promote timely initiation of breastfeeding. Choice D, 'After administering vitamin K,' is incorrect because breastfeeding initiation should not be delayed for this procedure.

Correct Answer: C

Rationale: Grunting with nasal flaring is a concerning sign of respiratory distress in a newborn that can indicate inadequate oxygenation. This finding requires immediate intervention to ensure the newborn's respiratory status is stabilized and to prevent further complications. Prompt assessment and appropriate intervention are crucial in such cases to prevent respiratory compromise and potential deterioration. Acrocyanosis, which is bluish discoloration of the extremities, is a common finding in newborns and usually resolves on its own. A respiratory rate of 60 breaths per minute and a heart rate of 140 beats per minute are within normal ranges for a newborn and do not indicate immediate intervention is needed.
