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 C
Explanation
Delusions and loss of control can be distressing for the client and potentially disruptive to the unit environment. Moving the client to a quiet place helps create a calm and less stimulating environment, which can help reduce agitation and promote a sense of safety and security.
Using firmness and directing the client to sit for a while may escalate the situation and increase the client's distress. It is important to approach the client with empathy and provide a supportive environment rather than exerting control through firmness.
Suggesting the client take a walk or encouraging the client to use a punching bag may not be appropriate if the client is already displaying signs of agitation and losing control. These interventions may not address the underlying causes of the delusions and could potentially worsen the situation.
