ATI Pediatrics Proctored Test

Correct Answer: A

Rationale: In a 5-year-old boy with major trauma, a blood pressure of 70/40 mm Hg and a pulse rate of 140 beats/min, and weak, indicate decompensated shock. This presentation signifies inadequate perfusion, leading to compensatory mechanisms being overwhelmed, resulting in decompensated shock. Choice B is incorrect as the vital signs suggest the body is unable to adequately compensate for the trauma. Choice C is incorrect as the vital signs are more indicative of shock rather than increased intracranial pressure. Choice D is incorrect as such low blood pressure is not appropriate for a child of this age and indicates a critical condition.

Correct Answer: C

Rationale: A newborn is considered premature if it is born before 37 weeks gestation. Premature birth increases the risk of various health problems as the baby may not be fully developed. Choice A is incorrect because the weight alone does not determine prematurity. Choice B is incorrect as it refers to a specific situation but not a direct indicator of prematurity. Choice D is incorrect as the presence of meconium does not solely indicate prematurity.

Correct Answer: C

Rationale: Severe lower abdominal pain, light vaginal bleeding, and a history of missed periods are concerning for an ectopic pregnancy. The absence of a normal menstrual period along with these symptoms raises suspicion for an ectopic pregnancy, which requires immediate medical attention due to the risk of rupture and life-threatening complications. A normal pregnancy would typically present with different symptoms such as a positive pregnancy test and typical signs of early pregnancy. A ruptured ovarian cyst may present with similar symptoms but typically lacks the history of missed periods. A spontaneous abortion usually involves heavier bleeding and tissue passage, which is not described in this scenario.

Choice D is incorrect as such low blood pressure is not appropriate for a child of this age and indicates a critical condition.

Correct Answer: D

Rationale: If a newborn's heart rate is below 60 beats per minute, the appropriate action is to start positive-pressure ventilations. Ventilations help deliver oxygen to the newborn's body and support respiratory function, which is critical in cases of bradycardia. Chest compressions are not recommended until the heart rate is below 60 despite adequate ventilation. Reassessment is essential but not the immediate action required in this scenario. Administering blow-by oxygen alone may not effectively address the underlying cause of bradycardia, making positive-pressure ventilations the priority intervention in this case.
