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:
Discouraging the parents from allowing siblings to view the body can prevent healthy grieving and closure for the siblings. Allowing siblings to view the body, if they wish, can help them understand the reality of the situation and cope with their emotions in a healthy way.
Choice B rationale:
Providing a follow-up phone call 1 week following the infant's death is a good practice, but it is not the most immediate and crucial action in this situation. Acknowledging the family's feelings of guilt and providing emotional support should take precedence.
Choice C rationale:
Avoiding discussing details of the attempt to revive the infant might hinder the family's ability to process the situation. Open communication, including discussing the events leading to the infant's death, can help the family members come to terms with their loss.
Choice D rationale:
Acknowledging the family members' feelings of guilt is the correct choice. Parents and family members often experience guilt after the death of an infant from SIDS, wondering if there was something they could have done differently. The nurse should acknowledge these feelings and provide reassurance, emphasizing that SIDS is not the result of parental actions or negligence.
Correct Answer is A
Explanation
Choice A rationale:
Assess respiratory status. In a child with a head injury, assessing respiratory status is the top priority. Respiratory distress or compromise could indicate potential brain injury or other serious complications. Ensuring an open airway, adequate breathing, and proper oxygenation is essential for the child's immediate well-being. Any signs of respiratory distress should be promptly addressed to prevent further complications.
Choice B rationale:
Check pupil reactions. Checking pupil reactions is important in assessing neurological function, but it is secondary to assessing respiratory status in this scenario. Respiratory status takes precedence because impaired breathing can lead to hypoxia, which can further compromise neurological function. Once respiratory status is stabilized, assessing neurological signs, including pupil reactions, becomes crucial to evaluate potential brain injury.
Choice C rationale:
Inspect for fluid leaking from the ears. Inspecting for fluid leaking from the ears is important in head injury assessment, specifically for signs of cerebrospinal fluid leakage. However, it is not the first action to take. Assessing respiratory status and ensuring proper oxygenation are immediate
