ATI Pediatric Medications Test

Correct Answer: B

Rationale: Type 2 diabetes mellitus is most likely the result of heterogeneous risk factors, such as lifestyle choices and genetics, making it preventable. Type 1 diabetes, on the other hand, is an autoimmune condition that is not preventable. Gestational diabetes occurs during pregnancy and is not entirely preventable. Type 1 and 2 diabetes are distinct conditions, with Type 2 being the type associated with preventable risk factors.

Correct Answer: A

Rationale: Encouraging the infant's parents to remain at the bedside and actively participate in the infant's care is crucial in decreasing the stressors of hospitalization for the infant. Parental presence provides comfort and security, promotes bonding, and maintains a sense of familiarity for the infant during a potentially stressful situation. This involvement can help reduce anxiety and promote better outcomes for the infant's emotional well-being and overall hospital experience. Providing a brightly lit environment (choice B) can actually increase stress for the infant, as infants generally prefer dimly lit environments for better sleep. Playing tapes of the mother's voice (choice C) may offer some comfort but does not substitute for parental presence. While assigning the same nurse to the infant (choice D) can provide continuity of care, it is not as effective as having the parents present for emotional support and bonding.

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: B

Rationale: In typhoid fever, the rash typically appears on the third day after symptoms first appear. This rash can help in diagnosing the disease along with other symptoms such as fever, malaise, and abdominal pain. Choices A, C, and D are incorrect because the rash in typhoid fever usually appears on the third day, not the second, fourth, or seventh day after the symptoms begin.

Correct Answer: A

Rationale: To calculate the safest dose of amoxicillin for Atta, we multiply the weight (20kg) by the daily dose (50 mg/kg/day) which equals 1000 mg/day. Since the dose is to be given in two divided doses, the safest dose for each administration would be 500 mg. Therefore, the correct answer is 1000 mg, as it aligns with the prescribed dose for this child based on weight and dosing guidelines. Choice B, 750 mg, is incorrect as it does not match the calculated daily dose. Choice C, 500 mg, is incorrect as it represents the safest dose for each administration, not the total daily dose. Choice D, 250 mg, is incorrect as it is below the calculated daily dose required for the child.
