ATI Pediatric Proctored Exam

Correct Answer: A

Rationale: In ataxic cerebral palsy, the characteristic features include hypotonia (low muscle tone) and muscle instability. These manifestations contribute to the infant's difficulty in achieving independent sitting. Hypertonia (increased muscle tone) and persistence of primitive reflexes, as mentioned in option B, are more commonly associated with other types of cerebral palsy. Tremors and exaggerated posturing (option C) are not typical features of ataxic CP. Hemiplegia (paralysis of one side of the body) and hypertonia (increased muscle tone) mentioned in option D are more commonly seen in other types of cerebral palsy, such as spastic CP.

Correct Answer: B

Rationale: Turning and repositioning the infant every 4 hours is essential to prevent pressure sores and ensure uniform exposure to phototherapy. This practice helps prevent skin breakdown and ensures the effectiveness of the phototherapy in treating hyperbilirubinemia.

Correct Answer: D

Rationale: An INR level of 1.2 is below the therapeutic range (2-3) for warfarin therapy. Therefore, the nurse should contact the healthcare provider to discuss the need for an increased dose to achieve the desired therapeutic range and prevent deep vein thrombosis effectively.

Correct Answer: C

Rationale: The nurse should instruct the guardian to keep the baby�s crib away from the radiator to prevent burns.

Correct Answer: B

Rationale: To calculate the corrected age of a premature child, you need to adjust for the weeks of prematurity. In this case, the child was born at 30 weeks gestation. From May 2, 2014, to August 5, 2014, is a span of 14 weeks. Subtracting the 30 weeks of gestation from the total time passed (14 weeks) gives the corrected age, which is 14 - 30 = -16 weeks. Since negative weeks are not relevant here, the corrected age is 0 weeks, which is equivalent to 2 weeks.
