An infant who weighs 22 pounds receives a prescription for amoxicillin 20 mg/kg/day by mouth in divided doses every 8 hours. The bottle is labeled, "Amoxicillin for Oral Suspension, USP 250 mg per 5 mL." How many mL should the nurse administer with each dose? (Enter numerical value only. If rounding is necessary, round to the nearest tenth.)
The Correct Answer is ["1.3"]
1. Convert the infant's weight from pounds to kilograms. We can use the conversion factor 1 kg
= 2.2 lb. So, 22 lb x (1 kg / 2.2 lb) = 10 kg.
2. Calculate the total daily dose of amoxicillin for the infant. We can use the formula D = d x W, where D is the total daily dose, d is the dose per kg per day, and W is the weight in kg. So, D = 20 mg x 10 kg = 200 mg.
3. Calculate the single dose of amoxicillin for the infant. We can divide the total daily dose by the number of doses per day. Since the prescription is for every 8 hours, there are 3 doses per day. So, 200 mg / 3 = 66.67 mg.
4. Calculate the volume of amoxicillin suspension for the single dose. We can use the ratio of the concentration of the suspension, which is 250 mg per 5 mL. So, 66.67 mg x (5 mL / 250 mg) =
1.33 mL.
5. Round the volume to the nearest tenth= 1.3 mL

Correct Answer is D
Explanation
A) Incorrect - Initiating continuous dopamine infusion is not a priority in this situation. The client's low blood pressure and electrolyte imbalances require more immediate attention.
B) Incorrect - Administering promethazine addresses symptoms like nausea and vomiting, but it doesn't address the primary issue of hypovolemia and low blood pressure.
C) Incorrect - Administering potassium chloride without addressing the fluid deficit can be dangerous and may lead to further electrolyte imbalances.
D) Correct- The client's vital signs and laboratory results indicate hypovolemia (low blood pressure, low sodium, and low potassium). The immediate priority is to address the fluid deficit and correct the electrolyte imbalances. Administering a bolus of 0.9% sodium chloride (normal saline) will help increase intravascular volume and improve blood pressure, as well as correct the electrolyte imbalances to some extent.
Correct Answer is ["B","C","E"]
Explanation
A) Incorrect - Red blood cell count (RBC) is not directly relevant to the assessment of infection and its spread.
B) Correct- Core body temperature can be an indicator of systemic infection and needs to be reported to the healthcare provider for assessment and intervention.
C) Correct- Swollen lymph nodes in the groin suggest local and regional lymphatic involvement, indicating possible spread of infection. This finding needs further assessment and intervention.
D) Incorrect - The location of the initial intravenous (IV) site is not directly relevant to the assessment of infection and its spread.
E) Correct- An elevated white blood cell count (WBC) can indicate an inflammatory response to infection. This finding should be reported to the healthcare provider for further evaluation and treatment.
