A nurse is preparing to administer amoxicillin 80 mg/kg/day divided into two doses daily to a 2-year-old client who weighs 10 kg (22 lb) Available is amoxicillin suspension 400 mg/5 mL. How many mL of amoxicillin should the nurse administer per dose? (Round the answer to the nearest whole number.
Use a leading zero if it applies.
Do not use a trailing zero.)
8 mL
80 mL
10 mL
5 mL
The Correct Answer is D
The correct answer is Choice D: 5 mL.
Choice A: 8 mL This choice suggests administering 8 mL of amoxicillin per dose. However, based on the child’s weight (10 kg) and the prescribed dosage (80 mg/kg/day divided into two doses), the correct calculation leads to a dosage of 5 mL per dose. Therefore, 8 mL would be more than the recommended dosage.
Choice B: 80 mL Administering 80 mL of amoxicillin per dose would be significantly more than the recommended dosage. This could potentially lead to an overdose, which could cause harmful side effects.
Choice C: 10 mL While 10 mL is close to the correct dosage, it is still double the recommended amount. Administering too much amoxicillin could potentially lead to an overdose and cause harmful side effects.
Choice D:
Step 1: Calculate the total amount of amoxicillin needed per day.
The total amount of amoxicillin needed per day is calculated by multiplying the weight of the child by the dosage per kg. So, 80 mg/kg/day × 10 kg = 800 mg/day.
Step 2: Divide the total amount of amoxicillin needed per day by the number of doses per day.
The total amount of amoxicillin needed per day is divided into two doses. So, 800 mg/day ÷ 2 = 400 mg/dose.
Step 3: Calculate the volume of amoxicillin suspension needed per dose.
The volume of amoxicillin suspension needed per dose is calculated by dividing the amount of amoxicillin needed per dose by the concentration of the suspension. So, 400 mg/dose ÷ (400 mg/5 mL) = 5 mL/dose.
Therefore, the nurse should administer 5 mL of amoxicillin per dose.

Correct Answer is ["A","D","E"]
Explanation
Choice A rationale: Offering the infant a pacifier during feedings can help with non-nutritive sucking, which is beneficial for the development of oral motor skills. It can also provide comfort and a sense of normalcy for the infant during tube feedings. This practice is encouraged to promote positive feeding experiences and support the infant's overall development.
Choice B rationale: Placing the infant in a supine position during feedings is not recommended due to the increased risk of aspiration. The preferred position is to keep the infant in an upright or semi-upright position to facilitate proper digestion and reduce the risk of gastroesophageal reflux and aspiration. Proper positioning is crucial for the safety and well-being of the infant during enteral feedings.
Choice C rationale: Heating the formula to 39°C (102°F) is not advised as it can be too hot and cause burns or discomfort to the infant. The formula should be administered at room temperature or slightly warmed to body temperature to ensure it is safe and comfortable for the infant. Proper temperature regulation is important to prevent thermal injuries.
Choice D rationale: Checking for residual volumes by aspirating stomach contents is an important step in assessing the infant's tolerance to the feeding. It helps determine if the previous feeding has been adequately digested and can indicate potential issues such as delayed gastric emptying. Regular assessment of residual volumes is a standard practice in managing enteral feedings for infants.
Choice E rationale: Instilling the formula over a period of 30 to 45 minutes is recommended to mimic normal feeding patterns and promote proper digestion. Slow and controlled administration of the feeding reduces the risk of gastrointestinal discomfort and aspiration. It also allows for better tolerance and absorption of the nutrients in the formula.
Correct Answer is C
Explanation
Choice A rationale:
Allowing the child to adjust their bedtime might promote autonomy, but in a hospital setting, routine and familiarity are essential for reducing anxiety in school-age children. Disrupting their home sleep routine may increase stress and hinder the child's ability to rest properly.
Choice B rationale:
Leaving the lights on in the child's room contradicts the principles of creating a sleep-conducive environment. Adequate sleep hygiene involves a dark and quiet room. Leaving lights on could interfere with the child's ability to fall asleep, potentially leading to sleep disturbances and increased anxiety.
Choice C rationale:
Following the child's home sleep routine is the most appropriate intervention. Maintaining consistency with the child's usual bedtime routine provides a sense of familiarity and security, reducing anxiety and promoting better sleep. This approach aligns with the principles of pediatric nursing, ensuring the child's emotional well-being while in the hospital.
Choice D rationale:
Providing the child with video games prior to bedtime is not recommended, especially in a hospital setting. Screen time, especially before sleep, can disrupt sleep patterns due to the blue light emitted by electronic devices. Additionally, video games may stimulate the child, making it harder for them to relax and fall asleep. This choice can exacerbate the child's stress and hinder their ability to achieve adequate sleep.
