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. Spina bifida.
Explanation: Correct Choice. Spina bifida is a neural tube defect (NTD) that occurs during early fetal development when the neural tube doesn't close completely. It can result in various degrees of spinal cord and nerve damage. This is a suitable example to include when teaching about neural tube defects.
B. Hydrocephalus.
Explanation: Hydrocephalus is not a neural tube defect itself. It's a condition characterized by the accumulation of cerebrospinal fluid in the brain, leading to increased intracranial pressure. It can be caused by various factors, but it's not directly related to neural tube development.
C. Cerebral palsy.
Explanation: Cerebral palsy is a group of motor disorders caused by damage to the developing brain, usually before birth. It is not a neural tube defect. Instead, it's related to brain injury or abnormal development.
D. Muscular dystrophy.
Explanation: Muscular dystrophy is a group of genetic disorders characterized by progressive muscle weakness and degeneration. It's not related to neural tube defects. Muscular dystrophy affects muscle tissue, while neural tube defects involve improper development of the neural tube.
