A child who weighs 18 pounds receives a prescription for amoxicillin 25 mg/kg/day by mouth in divided doses every 12 hours. The bottle is labelled, "Amoxicillin for Oral Suspension, USP 400 mg per 5 mL." How many mL should the nurse administer with each dose?
(Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.3"]
1.3 mL of amoxicillin suspension with each dose.
To calculate the correct dose of amoxicillin to give to the child, follow these steps:
Step 1: Convert the child's weight from pounds to kilograms. 18 pounds ÷ 2.2 = 8.18 kilograms
Step 2: Calculate the total daily dose of amoxicillin. 25 mg/kg/day x 8.18 kg = 204.5 mg/day
Step 3: Divide the total daily dose into two equal doses to be given every 12 hours. 204.5 mg/day ÷ 2 doses = 102.25 mg/dose
Step 4: Determine how many mL of the suspension contain 102.25 mg of amoxicillin. 400 mg/5 mL = 80 mg/mL 102.25 mg ÷ 80 mg/mL = 1.28 mL

Correct Answer is C
Explanation
Acute rheumatic fever is a serious inflammatory condition that can develop after a streptococcal infection, particularly if the infection is not treated or resolved properly. The most common initial symptom of acute rheumatic fever is a sore throat, which is usually accompanied by a fever and swollen lymph nodes.
While mumps, chickenpox, and influenza are all infectious diseases, they are not directly linked to the development of acute rheumatic fever. However, a recent or untreated streptococcal infection (such as strep throat) can lead to the development of acute rheumatic fever.
Therefore, when obtaining a health history from a child with a diagnosis of acute rheumatic fever, it is most significant to inquire about recent or untreated sore throat, as this is the most likely cause of the condition.
Correct Answer is C
Explanation
Answer: C. Red blood cell count of 2.3 cells/mcl or (2.3 x 10/L).
Rationale:
A. White blood cell count of 10,000/mm³ (10 x 10⁹/L): This is within the normal range for an infant, indicating no immediate concern for infection or immune response. It does not need to be urgently conveyed to the surgeon.
B. Weight gain of 2 pounds (0.91 kg) since birth: This is a positive sign indicating healthy growth and nutritional status, but it is not a critical concern that would affect the immediate surgical plan.
C. Red blood cell count of 2.3 cells/mcl or (2.3 x 10⁹/L): This low RBC count indicates anemia, which is critical information for the surgeon. Anemia can increase the risk of complications during and after surgery due to potential issues with oxygenation and healing, making it the most important information to convey.
D. Urine specific gravity is 1.011: This indicates normal hydration status and is not immediately relevant to the surgical procedure. It does not need to be urgently reported to the surgeon compared to the low RBC count.
