ATI PN Pediatrics Proctored Exam 2020 Questions
Question 1 of 5
What complication of his original lesion best explains his heart failure?
Correct Answer: B
Rationale: A 12-year-old with a small ventricular septal defect (VSD) presents with heart failure, a pansystolic murmur, and an early diastolic murmur, suggesting aortic valve regurgitation (Choice B). Over time, a VSD can distort the aortic root, leading to aortic regurgitation, increased left ventricular volume, and heart failure. Acute rheumatic fever (Choice A) requires fever and inflammation, absent here. Eisenmenger syndrome (Choice C) involves cyanosis from shunt reversal, not present. An increasing left-to-right shunt (Choice D) wouldn’t cause a diastolic murmur. Aortic regurgitation fits the clinical findings.
Question 2 of 5
The best diagnostic clue of pulmonary tuberculosis (TB) is:
Correct Answer: A
Rationale: Isolation of M. tuberculosis from culture is the gold standard for TB diagnosis, providing definitive evidence (CDC). Options B-E are supportive but less specific.
Question 3 of 5
Most common organism responsible for acute hemorrhagic conjunctivitis is:
Correct Answer: A
Rationale: Enterovirus 70 is the primary cause of acute hemorrhagic conjunctivitis, known for outbreaks with hemorrhage (WHO). Other viruses (B-E) are less common.
Question 4 of 5
A 16-month-old boy refuses to eat properly. His mother stated that he was eating properly up to 12 months of age. She started a part time job 2 months ago. She is extremely concerned. The boy is very active. The next step in management is:
Correct Answer: D
Rationale: Reassurance suits an active 16-month-old with reduced appetite, possibly due to maternal stress or toddler phase (AAP). A-D are unnecessary without deficiency.
Question 5 of 5
All of the following conditions cause fetal bradycardia (heart rate less than 120 beats/minute) except:
Correct Answer: C
Rationale: Local anesthetics don’t typically cause fetal bradycardia; A-D are known causes (ACOG).
