A nurse is preparing to administer amoxicillin 30 mg/kg/day divided equally every 12 hr to a toddler who weighs 33 lb. Available is amoxicillin 200 mg/5 mL suspension. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["5.625"]
To calculate the dose of amoxicillin for the toddler:
Step 1: Convert the toddler's weight from pounds to kilograms.
33 lb ÷ 2.2 (lb to kg conversion factor) = approximately 15 kg
Step 2: Calculate the total daily dose of amoxicillin.
Dose = 30 mg/kg/day × 15 kg = 450 mg/day
Step 3: Divide the total daily dose into equal doses every 12 hours.
450 mg/day ÷ 2 doses = 225 mg/dose
Step 4: Calculate the amount of amoxicillin suspension needed for each dose.
The available concentration is 200 mg/5 mL, so for 225 mg, you would use the proportion:
225 mg : 200 mg = x mL : 5 mL
Cross-multiplying: x = (225 mg × 5 mL) / 200 mg ≈ 5.625 mL
Therefore, the nurse should administer approximately 5.625 mL of amoxicillin suspension for each dose.

Correct Answer is A
Explanation
A) Vaccinations to prevent pneumococcal and Haemophilus influenzae type B meningitis are available.
Explanation: This statement is true. Vaccinations to prevent certain types of bacterial meningitis are available. Pneumococcal and Haemophilus influenzae type B (Hib) vaccines are included in routine childhood immunization schedules to protect against the bacteria that can cause meningitis and other serious infections. These vaccines have significantly reduced the incidence of bacterial meningitis in infants and children.
B) Often a genetic predisposition to meningitis is found.
Explanation: This statement is generally false. While there may be some genetic factors that influence susceptibility to infections, including meningitis, genetic predisposition is not a primary consideration when discussing the risk of meningitis. Meningitis is more commonly caused by bacterial or viral infections, and genetic predisposition is not a significant factor in its occurrence.
C) Meningitis rarely occurs during infancy.
Explanation: This statement is false. Meningitis can occur in infants, including newborns. In fact, infants are one of the age groups at higher risk for meningitis due to their underdeveloped immune systems and susceptibility to infections. Bacterial meningitis, in particular, can be severe and life-threatening in infants.
D) Vaccination to prevent all types of meningitis is now available.
Explanation: This statement is not entirely accurate. While vaccinations are available to prevent certain types of bacterial meningitis (such as pneumococcal and Hib meningitis), there is no single vaccine that can prevent all types of meningitis. Meningitis can be caused by various bacteria, viruses, and other pathogens, and the vaccines target specific ones. It's important for caregivers to ensure that their infants receive recommended vaccines to protect against the most common causes of meningitis.
Correct Answer is A
Explanation
A) A step-wise approach will be used to reduce the dosage gradually.
Explanation:
After a certain period of seizure control, a healthcare provider may consider gradually tapering and discontinuing anti-seizure medications in consultation with the child's neurologist. This is often done in a step-wise manner to monitor the child's condition and minimize the risk of seizure recurrence. Stopping anti-seizure medications abruptly can increase the risk of seizures returning. Therefore, the response provided in option A is the most accurate and relevant to the situation.
The other options are incorrect:
B) Your child will always suffer seizures:
This statement is not accurate, as some children with epilepsy can achieve long-term seizure control with appropriate treatment. Epilepsy management varies from person to person, and many individuals can experience extended periods of seizure freedom.
C) This is always a hereditary disorder:
Epilepsy can have both genetic and non-genetic causes. While there are genetic forms of epilepsy, not all cases are hereditary. Epilepsy can be caused by a variety of factors, including brain injuries, infections, and other medical conditions.
D) Only her male offspring will experience seizures:
Epilepsy does not discriminate based on gender. Both males and females can be affected by epilepsy. This statement is not accurate and does not reflect the reality of epilepsy as a medical condition.
