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 C
Explanation
Correct Answer is ["A","B","D"]
Explanation
A) Preventing further Urinary Tract Infections:
This is a relevant priority for patients with reflux. Vesicoureteral reflux (VUR) is a condition where urine flows backward from the bladder into the ureters and sometimes to the kidneys, increasing the risk of urinary tract infections (UTIs). Preventing UTIs is important because recurring infections can lead to more severe kidney problems and complications. Teaching patients and caregivers about hygiene, proper voiding techniques, and recognizing UTI symptoms is crucial to minimize the risk of infections.
B) Preventing kidney damage:
Preventing kidney damage is a significant priority for patients with reflux. If urine refluxes back into the kidneys, it can lead to kidney damage over time. This damage can affect kidney function and potentially lead to chronic kidney disease. Monitoring kidney function, managing UTIs promptly, and considering medical or surgical interventions to correct reflux are all important strategies to prevent kidney damage.
C) The chances of needing brain surgery:
The chances of needing brain surgery are not directly related to reflux. Reflux primarily involves the urinary system, specifically the flow of urine from the bladder to the kidneys. Brain surgery is not a relevant consideration in the context of reflux or its management.
D) Antibiotic usage teaching with the presence of an infection:
This is an important aspect of care for patients with reflux who develop urinary tract infections. UTIs are common complications of reflux, and appropriate use of antibiotics is crucial to treat infections effectively and prevent further complications. Teaching patients and caregivers about the importance of completing prescribed antibiotic courses, recognizing signs of infection, and adhering to medical advice is essential to manage UTIs in the presence of reflux.
