ATI Pediatric Proctored Exam 2023

Correct Answer: B

Rationale: A sodium level of 140 mEq/L within the expected reference range indicates effective treatment for dehydration. In dehydration, sodium levels are often elevated, so a normal sodium level suggests that the treatment is helping to restore the electrolyte balance in the infant's body.

Correct Answer: B

Rationale: The correct answer is Perceptual Learning. In this stage, the toddler learns from sensory input and refines their movements over time, even though errors may still occur. This process involves improving coordination and fine-tuning motor skills based on feedback from repeated attempts.

Correct Answer: A

Rationale: Minimal change nephrotic syndrome (MCNS) is characterized by massive proteinuria, hypoalbuminemia, and edema. Proteinuria results from the loss of proteins, particularly albumin, in the urine, leading to hypoalbuminemia. The low oncotic pressure due to hypoalbuminemia causes fluid to shift into the interstitial spaces, resulting in edema. These clinical manifestations are classic signs of MCNS and help differentiate it from other renal conditions.

Correct Answer: B

Rationale: In a child with a head injury, the development of diabetes insipidus can occur due to pituitary hypofunction, leading to a deficiency of antidiuretic hormone. An elevated sodium level (hypernatremia) is a key finding in diabetes insipidus due to the excessive loss of free water in the urine, resulting in increased sodium concentration in the blood.

Correct Answer: C

Rationale: The correct answer is hypotonic dehydration. The combination of high hemoglobin and hematocrit with low serum sodium indicates hypotonic dehydration. In this condition, there is an excess of solutes relative to water, leading to higher red blood cell concentration (elevated hemoglobin and hematocrit) and low serum sodium levels.
