The Health Care Provider prescribes Amoxicillin at a dosage of 35mg/kg/dose for a child who weighs 34 lbs. and has Otitis Media. The medication is available in a suspension of 50 mg/ml. What is the total daily dosage in ml for this child?
10 ml
20 ml
30 ml
40 ml .
The Correct Answer is A
Step 1 is to convert the child’s weight from pounds to kilograms.
This is done by dividing the weight in pounds by 2.2, so 34 lbs ÷ 2.2 = 15.45 kg. Step 2 is to calculate the dose in mg. This is done by multiplying the weight in kg by the dosage per kg, so 15.45 kg × 35 mg/kg = 540.75 mg. Step 3 is to convert the dose in mg to ml. This is done by dividing the dose in mg by the concentration of the medication in mg/ml, so 540.75 mg ÷ 50 mg/ml = 10.815 ml. So, the total daily dosage in ml for this child is approximately 10.82 ml, rounded to the nearest hundredth as required.

Correct Answer is B
Explanation
Choice A rationale:
Abdominal rigidity and pain on palpation are not typical signs of pyloric stenosis. Pyloric stenosis usually presents with non-bilious projectile vomiting, a palpable olive-shaped mass in the upper abdomen, and signs of dehydration.
Choice B rationale:
A rounded abdomen and hypoactive bowel sounds are characteristic signs of pyloric stenosis. The hypertrophied pyloric muscle obstructs the passage of food from the stomach to the duodenum, leading to gastric distention, visible peristalsis, and vomiting. The infant may appear hungry after vomiting and will continue to feed, leading to weight loss.
Choice C rationale:
Visible peristalsis and weight loss are consistent with pyloric stenosis. The visible peristalsis occurs as the infant tries to force the stomach contents through the narrowed pyloric sphincter. Weight loss is a result of poor feeding and vomiting.
Choice D rationale:
Distention of the lower abdomen and constipation are not typical findings in pyloric stenosis. Constipation suggests a lower gastrointestinal issue, while pyloric stenosis primarily affects the upper gastrointestinal tract.
Correct Answer is B
Explanation
Choice A rationale
It’s not advisable to follow the directions on the aspirin bottle for her age and weight. Aspirin is not recommended for use in children due to the risk of Reye’s syndrome, a rare but serious condition that can affect the liver and brain.
Choice B rationale
This is the correct response. Acetaminophen is a safer alternative to aspirin for managing fever in children.
Choice C rationale
While it’s generally a good idea to administer medication with food to prevent stomach upset, this advice does not address the specific risks associated with giving aspirin to a toddler.
Choice D rationale
Giving a toddler three baby aspirin every 4 hours is not recommended due to the risk of Reye’s syndrome.
