A pediatric patient weighing 22 kg is prescribed amoxicillin 50 mg/kg/day in divided doses every 8 hours. The medication is available as a suspension containing 125 mg/5 mL. How many mL of the suspension should the nurse administer for each dose?
11.67 mL
14.67 mL
15.67 mL
17.67 mL
The Correct Answer is B
Calculate the total daily dose in milligrams (mg).
Total daily dose (mg) = Prescribed dose (mg/kg/day) × Weight (kg)
= 50 mg/kg/day × 22 kg
= 1100 mg/day.
Determine the number of doses per day:
Doses are given every 8 hours, so Number of doses per day = 24 hours / 8 hours
= 3 doses/day.
Calculate the dose per administration in milligrams (mg).
Dose per administration (mg) = Total daily dose (mg) / Number of doses per day
= 1100 mg / 3 doses
= 366.666 mg.
Available concentration of the amoxicillin suspension:
= 125 mg / 5 mL.
Calculate the volume in milliliters (mL) to administer for each dose.
Volume per dose (mL) = Desired dose per administration (mg) / (Available concentration (mg) / Available volume (mL))
Volume per dose (mL) = 366.666 mg / (125 mg / 5 mL)
= 366.666 mg × (5 mL / 125 mg)
= (366.666 × 5) / 125 mL
= 1833.33 / 125 mL
= 14.666 mL.
=14. 67 mL

Correct Answer is B
Explanation
Calculation:
Determine the recommended daily fluid maintenance for a baby weighing up to 10 kg.
- For the first 10 kg of body weight, the recommended fluid maintenance is 100 mL/kg/day.
Calculate the total daily fluid maintenance for the baby.
Total daily fluid maintenance (mL/day) = Weight (kg) × 100 mL/kg/day
= 8 kg × 100 mL/kg/day
= 800 mL/day.
Convert the total daily fluid maintenance to an hourly rate.
Fluid maintenance rate (mL/hr) = Total daily fluid maintenance (mL/day) / 24 hr/day
= 800 mL / 24 hr
= 33.333... mL/hr.
= 33.3 mL/hr.
Correct Answer is A
Explanation
A. "It is expected for children who are hospitalized to regress. The toileting skills will return when your child is feeling better." Hospitalization can be stressful and disruptive for children, often causing temporary regression Reassuring parents that this behavior is common and usually resolves as the child recovers helps reduce parental anxiety and supports understanding.
B. "Why does it bother you that your child has wet the bed?" This response may come across as confrontational or judgmental, potentially increasing the parent's distress rather than providing comfort or support during a vulnerable moment.
C. "I know this can really be embarrassing. I have kids myself, so I understand, and it doesn't bother me." While this statement shows empathy, it may unintentionally shift focus to the nurse’s experience rather than validating the parent’s feelings. A more supportive response addresses the child’s needs and parental concerns directly.
D. "Your child did not seem upset, so I wouldn't worry about it if I were you." Dismissing the parent's feelings about the situation may cause them to feel unheard or invalidated. Acknowledging the parent's emotions while providing reassurance is a more supportive approach.
