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 D
Explanation
Choice A rationale:
Staying under a beach umbrella during morning hours provides some protection from direct sunlight but does not offer comprehensive coverage, especially when the sun's rays are strong. It is not the best option for protecting a toddler from sun exposure.
Choice B rationale:
SPF (Sun Protection Factor) 10 sunscreen is relatively low and may not provide adequate protection, especially for a toddler. Higher SPF sunscreens are recommended, typically SPF 30 or higher, to effectively block harmful UV rays.
Choice C rationale:
Loose-weave clothing may allow sunlight to penetrate, leading to sunburn. Tight-knit, dark-colored clothing offers better protection. Loose-weave clothing is not the most effective choice for sun protection.
Choice D rationale:
Wearing a wide-brimmed hat provides shade to the face, neck, and ears, offering additional protection from direct sunlight. This choice indicates a good understanding of the need for comprehensive sun protection for the toddler.
Correct Answer is D
Explanation
Choice A rationale: Telling the child that the medication tastes like candy can be misleading and might contribute to a misunderstanding about the purpose and importance of medication. It's important to maintain honesty and build trust with the child, rather than using such statements.
Choice B rationale: Explaining that the medication will treat the hypersensitivity reaction uses medical terminology that may be too complex for a preschooler to understand. This explanation is more suited for older children or adults who can comprehend such information.
Choice C rationale: Allowing the preschooler to decide when to take the medication can delay treatment and may not be practical in urgent situations. While giving some sense of control to the child is important, the nurse must ensure timely administration of the medication to manage the hypersensitivity reaction.
Choice D rationale: Acknowledging the child’s feelings by saying that sometimes children feel sad when they have to take medication helps validate the child's emotions and can build trust. This approach is more likely to calm the child and make them feel understood, potentially making it easier to administer the medication.
