A nurse is preparing to administer amoxicillin 100 mg PO every 8 hr to a toddler who weighs 20 kg. The recommended dosage range is 20 to 25 mg/kg/day. Which of the following actions by the nurse is appropriate?
The nurse contacts the pharmacist to adjust the prescribed dosage.
The nurse determines the prescription is insufficient to achieve the desired effect.
The nurse determines the prescription is above the recommended dosage range.
The nurse administers the prescribed dosage.
The Correct Answer is B
To calculate the appropriate dosage of amoxicillin for the toddler; Given:
Weight of the toddler = 20 kg
Recommended dosage range = 20 to 25 mg/kg/day Calculate the total daily dose:
Minimum recommended dosage = 20 mg/kg/day Maximum recommended dosage = 25 mg/kg/day
Minimum total daily dose = 20 mg/kg/day × 20 kg = 400 mg/day Maximum total daily dose = 25 mg/kg/day × 20 kg = 500 mg/day
The prescribed dosage is 100 mg every 8 hours, which means 300 mg per day (100 mg × 3 times a day). As 300 mg is below the minimum recommended total daily dose (400 mg) for a toddler weighing 20 kg, the nurse should determine that the prescribed dosage is insufficient to achieve the desired effect.

Explanation
A. The symptoms described, including slow onset of recurrent low-grade fever, fatigue, weakness, joint and muscle aches, loss of appetite, weight loss, and diaphoresis, along with the presence of a new heart murmur, splenomegaly, petechiae, splinter hemorrhages under the nails, and Osler nodes, are classic signs and symptoms of infective endocarditis (IE).
B. Tetralogy of Fallot is a congenital heart defect characterized by four specific abnormalities in the heart's structure. The symptoms described do not align with the characteristic features of Tetralogy of Fallot.
C. Acute rheumatic fever is an inflammatory condition that can develop as a complication of untreated streptococcal infections, particularly strep throat. While it can lead to heart valve damage (rheumatic heart disease), the symptoms described are more indicative of infective endocarditis rather than acute rheumatic fever.
D. Pulmonary hypertension is a condition characterized by elevated blood pressure in the pulmonary arteries. While it can present with symptoms such as fatigue and weakness, it typically does not manifest with the constellation of symptoms described, including fever, joint and muscle aches, and the presence of Osler nodes and splinter hemorrhages.
Correct Answer is A
Explanation
Children with CF often have pancreatic insufficiency, leading to malabsorption of nutrients. Pancreatic enzymes help digest fats, proteins, and carbohydrates, allowing for better absorption of nutrients from food.
B. This response is not specifically related to the nutritional management of CF. While individuals with CF may have increased salt loss through sweat and may need to consume more salt to maintain electrolyte balance, restricting salt is not typically part of CF nutrition management.
C. Hydration is important for individuals with CF to help maintain normal mucus consistency and prevent dehydration, especially during times of increased respiratory secretions.
D. Children with CF often have increased energy needs due to the increased work of breathing and malabsorption of nutrients. Therefore, it is important to provide a diet that is high in calories and nutrient-dense.
