ATI Pediatrics Proctored Test

Correct Answer: B

Rationale: The main function of the uterus is to house and nurture the growing fetus for approximately 40 weeks during pregnancy. It provides the necessary environment for the fetus to develop and grow until it is ready for birth. Choice A is incorrect as the cervix, not the uterus, dilates during labor to allow the baby to pass through. Choice C is incorrect as while the uterus does provide a protective environment, its primary function is not to act as a cushion. Choice D is incorrect as the placenta, not the uterus, is responsible for providing oxygen and nutrients to the fetus.

Correct Answer: D

Rationale: When assessing a small child's level of responsiveness, the most appropriate method is to tap the child and shout, 'Are you okay?' This approach is more likely to elicit a response from the child, providing a direct assessment of their level of consciousness and responsiveness. Palpating for a radial pulse (Choice A) is not the most direct method for assessing responsiveness in a child. Shouting at the child (Choice B) may startle them and not provide an accurate assessment. Asking the parent (Choice C) does not directly evaluate the child's responsiveness.

Correct Answer: B

Rationale: When encountering an unresponsive and not breathing child, the initial step is to open the airway and provide two rescue breaths. This action helps to deliver oxygen to the child's lungs and body, which is crucial in attempting to restore breathing and circulation. Chest compressions are not initiated first in pediatric cases unless the child has no signs of circulation after delivering rescue breaths. Applying an AED and analyzing the rhythm is not the initial step in a pediatric cardiac arrest scenario, as the primary focus should be on providing oxygenation. Asking the parent for the child's medical history is not the immediate priority when the child is unresponsive and not breathing, as interventions to support breathing and circulation should be the primary concern.

Correct Answer: D

Rationale: Capillary refill is a more reliable indicator of perfusion in children than in adults. This is because children have more compliant vessels, making capillary refill a more sensitive indicator of perfusion status in this population. In contrast, while blood pressure, heart rate, and respiratory rate are important indicators, they may not be as reliable in children as capillary refill. Blood pressure can be affected by various factors such as anxiety or pain, heart rate can be influenced by emotions or temperature, and respiratory rate may vary with activity levels. Therefore, capillary refill is preferred in children for a more accurate assessment of perfusion.

Correct Answer: B

Rationale: The correct answer is B. The presence of green vomit in a newborn is an abnormal finding and indicates a possible intestinal obstruction. This finding requires immediate attention and further investigation. Choices A, C, and D are normal findings in a newborn's abdomen assessment. A newborn typically has an umbilical cord with two arteries and one vein, a liver that may be palpable 1 to 2 cm below the costal margin due to its normal size in a neonate, and a soft, nondistended abdomen as expected in healthy newborns.
