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: B

Rationale: A heart rate of 80 beats per minute in a 3-month-old infant is abnormally low for that age group and could indicate underlying health issues. The normal heart rate for a 3-month-old infant is typically higher, around 100-150 beats per minute. Therefore, this finding stands out as abnormal and warrants further evaluation. Choice A is not necessarily abnormal in a newly born infant as irregular breathing patterns can be common during the neonatal period. Choice C falls within the normal respiratory rate range for a 2-year-old child, which is around 20-30 breaths per minute. Choice D reflects a systolic blood pressure value within the normal range for a 10-year-old child, which is typically around 90-110 mm Hg.

Correct Answer: C

Rationale: In a newborn with cyanosis to the chest and face and a heart rate of 90 beats/min, the priority action is to begin artificial ventilations. A heart rate below 100 beats/min with cyanosis indicates a need for immediate respiratory support to improve oxygenation. Drying the infant briskly or suctioning the mouth may be necessary later but are not the initial priority. Chest compressions are not indicated as the heart rate is above 60 beats/min.

Correct Answer: D

Rationale: The correct answer is D. Febrile seizures in children typically last less than 15 minutes and often do not have a postictal phase, meaning there is usually no prolonged recovery period or confusion after the seizure. They are commonly associated with the rapid rise in body temperature at the onset of a fever, rather than the duration of the fever itself. Choices A, B, and C are incorrect because febrile seizures can occur even after a child has had a fever for longer than 24 hours, they can be caused by viral or bacterial meningitis, and they do not have a typical pattern of occurring on the first day of a fever.

Correct Answer: C

Rationale: When assessing a 2-year-old child with abdominal pain and adequate perfusion, it is essential to examine the child in the parent's arms. This approach can help maintain the child's comfort, keep them calm, and increase their cooperation during the assessment. Placing the child supine and palpating the abdomen (Choice A) can be distressing and uncomfortable for the child. Separating the child from the parent (Choice B) may cause additional stress and hinder the examination process. Palpating the painful area first (Choice D) can lead to increased discomfort and resistance from the child.
