Distractors include 195 mL from halving, 780 mL from doubling, and 39 mL from decimal error. The calculation principle is direct weight times mL/kg. Double-checking math in pediatrics is important to restore hydration safely. A transferable strategy is to verify weight and order before calculation, and track intake.

This question tests pediatric dosage calculations and clinical judgment in medication administration. Accurate weight-based dosage calculations are crucial in pediatrics because adolescents with skin infections need proper antibiotic dosing to address self-consciousness. The correct answer of 210 mg per dose reflects the proper calculation by multiplying 42 kg by 20 mg/kg for 840 mg daily, then dividing by 4 doses. Distractors include 52.5 mg from dividing by 16, 840 mg from daily total, and 2,100 mg from using 50 mg/kg. The calculation principle calculates daily then divides by frequency. Double-checking math in pediatrics is important for treatment success. A transferable strategy is to confirm weight, dose, and divisions before calculating.

This question tests pediatric dosage calculations and clinical judgment in medication administration. Accurate weight-based dosage calculations are crucial in pediatrics because children have varying metabolic rates and organ maturity, increasing the risk of toxicity or subtherapeutic effects from errors. The correct answer of 4.2 mg reflects the proper calculation by multiplying the child's weight of 28 kg by the ordered dose of 0.15 mg/kg, yielding 4.2 mg. Distractors include 0.42 mg from misplaced decimal, 42 mg from ignoring the decimal in the order, and 2.8 mg from using 0.1 mg/kg instead. The calculation principle involves precise multiplication of weight in kg by the mg/kg order, considering decimals carefully. Double-checking math in pediatrics is important to avoid errors that could exacerbate conditions like asthma exacerbations. A transferable strategy is to verify weight and order before calculating, and use dimensional analysis for confirmation.

This question tests pediatric dosage calculations and clinical judgment in medication administration. Accurate weight-based dosage calculations are crucial in pediatrics because moderate dehydration in infants demands exact fluid volumes for recovery. The correct answer of 675 mL reflects the proper calculation by multiplying 9 kg by 75 mL/kg, yielding 675 mL over 4 hours. Distractors include 67.5 mL from decimal error, 900 mL from wrong weight, and 6,750 mL from adding a zero. The calculation principle is weight times mL/kg. Double-checking math in pediatrics is important to prevent complications. A transferable strategy is to verify weight and order before calculation.

This question tests pediatric dosage calculations and clinical judgment in medication administration. Accurate weight-based dosage calculations are crucial in pediatrics because adolescents' body compositions vary, and errors can delay recovery from infections like cellulitis. The correct answer of 675 mg per dose reflects the proper calculation by multiplying 54 kg by 25 mg/kg for 1,350 mg daily, then dividing by 2 doses. Distractors include 1,350 mg from giving the full daily dose at once, 135 mg from decimal error, and 2,700 mg from doubling the daily amount. The calculation principle involves first finding the daily total via weight times mg/kg/day, then dividing by the number of doses. Double-checking math in pediatrics is important to prevent antibiotic resistance or toxicity from overdosing. A transferable strategy is to verify weight, order, and dosing frequency before calculating, and check against standard references.

This question tests pediatric dosage calculations and clinical judgment in medication administration. Accurate weight-based dosage calculations are crucial in pediatrics because school-age children with fever need appropriate antipyretic dosing for comfort. The correct answer of 325 mg reflects the proper calculation by multiplying 26 kg by 12.5 mg/kg, yielding 325 mg. Distractors include 32.5 mg from decimal error, 2,600 mg from multiplying by 100, and 260 mg from using 10 mg/kg. The calculation principle handles decimals in multiplication. Double-checking math in pediatrics is important to avoid hepatotoxicity. A transferable strategy is to verify weight and order before calculation.

This question tests pediatric dosage calculations and clinical judgment in medication administration. Accurate weight-based dosage calculations are crucial in pediatrics because school-age children may have variable responses to bronchodilators, and errors can worsen respiratory distress. The correct answer of 3.2 mg reflects the proper calculation by multiplying 32 kg by 0.1 mg/kg, yielding 3.2 mg. Distractors include 0.32 mg from decimal error, 32 mg from ignoring the decimal, and 2.3 mg from using a different weight or order. The calculation principle involves careful multiplication with attention to decimals in mg/kg. Double-checking math in pediatrics is important to ensure effective symptom relief without side effects like tachycardia. A transferable strategy is to verify weight and order before calculating, and use a calculator for precision.
