ATI Pediatric Medications Test

Correct Answer: B

Rationale: The most indicative behavior of a 2-year-old experiencing the initial phase of separation anxiety due to parents not staying all day at the hospital is crying when his parents leave. This behavior is a common manifestation of separation anxiety in children, as they struggle with the absence of their primary attachment figures. Choices A, C, and D are less indicative because withdrawing from the nursing staff, lying quietly in bed, or crying when parents arrive do not specifically demonstrate the distress caused by separation from parents, which is the hallmark of separation anxiety in children.

Correct Answer: D

Rationale: In diabetic ketoacidosis (DKA), there is a state of dehydration and electrolyte imbalance. Normal saline is the initial fluid of choice to help restore intravascular volume and improve electrolyte balance. It also helps to correct acidosis. Potassium chloride IV infusion is commonly added to the treatment regimen once kidney function is confirmed to prevent hypokalemia. Dextrose 5% IV infusion is not the first-line treatment for DKA as it can worsen hyperglycemia. Ringer's Lactate is not typically used as the initial fluid for managing DKA as it contains potassium and could worsen hyperkalemia.

Correct Answer: A

Rationale: A ventricular septal defect allows blood to shunt left to right, leading to increased pulmonary flow. This results in oxygenated blood mixing with deoxygenated blood, causing no cyanosis as the mixed blood is still oxygenated. The shunting from left to right overloads the pulmonary circulation, leading to increased pulmonary flow. Choice B is incorrect because blood does not shunt right to left in a ventricular septal defect. Choice C is incorrect as shunting does occur due to the pressure differences between the ventricles. Choice D is incorrect because the defect affects the ventricles, not the atrium, and does not hinder the circulation of oxygenated blood in the circulating volume.

Correct Answer: A

Rationale: Hypopituitarism is characterized by linear growth retardation with skeletal proportions normal for chronologic age. This means that although the child experiences growth retardation, their skeletal proportions are appropriate for their age, which distinguishes it from other conditions like precocious puberty or equal height and weight affectation. Choice B is incorrect as hypopituitarism does not involve precocious puberty. Choice C is wrong as it describes a different growth pattern not typical of hypopituitarism. Choice D is also incorrect as in hypopituitarism, height and weight are not equally affected, rather the focus is on linear growth retardation with normal skeletal proportions.

Correct Answer: A

Rationale: The correct answer is A: 'The child vomits everything.' Vomiting everything is considered a danger sign in a child as it can lead to dehydration and other serious complications. Recognizing this sign early can help in timely intervention and management of the child's condition. Choices B and C are incorrect as diarrhea and headache, while concerning, are not specific danger signs highlighted in the Integrated Management of Neonatal and Childhood Illnesses.
