A child who weighs 25 kg is receiving IV ampicillin at a dose of 300 mg/kg/24 hours in equally divided doses every 4 hours. How many milligrams should the nurse administer to the child for each dose?

A. 1875 mg

B. 625 mg

C. 2000 mg

D. 1500 mg

Correct Answer: A
Rationale: To calculate the correct dose for each administration, you first need to find the total daily dose: 300 mg/kg * 25 kg = 7500 mg/day. Since this total dose is divided into equally divided doses every 4 hours, there are 6 doses in 24 hours. Therefore, 7500 mg ÷ 6 doses = 1250 mg per dose. The nurse should administer 1250 mg every 4 hours, resulting in a total of 1875 mg for each dose in a 24-hour period. Choice A, 1875 mg, is the correct answer. Choice B, 625 mg, is incorrect as it does not consider the total daily dose and the frequency of administration. Choice C, 2000 mg, is incorrect as it is not the calculated dosage based on the given parameters. Choice D, 1500 mg, is also incorrect as it does not reflect the correct dosage calculation for each dose.

The infant scheduled for reduction of intussusception passes a soft-formed brown stool the day before the scheduled procedure. Which intervention should the nurse implement?

• A. Instruct the parents that the infant needs to be NPO.
• B. Notify the healthcare provider of the passage of brown stool.
• C. Obtain a stool specimen for laboratory analysis.
• D. Ask the parents about recent changes in the infant's diet.

Correct Answer: B
Rationale: Notifying the healthcare provider is crucial in this situation because the passage of a brown stool may indicate the resolution of intussusception. It is important to keep the healthcare provider informed about any changes in the infant's condition to ensure appropriate care and management. Instructing the parents that the infant needs to be NPO (nothing by mouth) is not necessary based on the passage of brown stool. Obtaining a stool specimen for laboratory analysis is not indicated in this scenario since the brown stool is likely a positive sign. Asking about recent changes in the infant's diet is not the priority at this moment as notifying the healthcare provider takes precedence.

What is the priority action for a 2-year-old child with croup presenting with a barking cough and stridor?

• A. Administer a corticosteroid
• B. Obtain a throat culture
• C. Administer nebulized epinephrine
• D. Place the child in an upright position

Correct Answer: C
Rationale: The priority action for a 2-year-old child with croup and stridor is to administer nebulized epinephrine. Nebulized epinephrine helps reduce airway swelling, alleviate symptoms, and improve breathing by causing vasoconstriction and reducing upper airway edema. Administering a corticosteroid may be done but is not the priority in this scenario. Obtaining a throat culture is not necessary for the immediate management of croup. Placing the child in an upright position can aid in breathing but is not the priority action when the child is presenting with stridor.

The healthcare provider plans to screen only the highest risk children for scoliosis. Which group of children should the healthcare provider screen first?

• A. Girls between ages 10 and 14.
• B. Boys between ages 10 and 14.
• C. Boys and girls between 12 and 14.
• D. Boys and girls between 8 and 12.

Correct Answer: A
Rationale: Corrected Question: The healthcare provider plans to screen only the highest risk children for scoliosis. Which group of children should the healthcare provider screen first? Girls between ages 10 and 14 are at the highest risk for scoliosis and should be screened first as they have a higher incidence of developing scoliosis during their adolescent growth spurt. Early detection and intervention can help prevent further complications associated with scoliosis. Boys between ages 10 and 14 (choice B) are not at the highest risk compared to girls in the same age group. Boys and girls between 12 and 14 (choice C) are at a lower risk compared to girls between ages 10 and 14. Boys and girls between 8 and 12 (choice D) are at a lower risk group compared to girls between ages 10 and 14.

• A. Initiate a structured eating plan for the client
• B. Establish a therapeutic relationship with the client
• C. Monitor the client’s electrolyte levels
