A nurse is caring for a client who requires a sterile dressing change. The nurse should recognize that the surgical field has been contaminated if which of the following actions occur?
A pair of sterile forceps is allowed to rest in a container of sterile water on the field.
The sterile solution is poured with the bottle held over the field.
Unnecessary sterile items are placed on the field.
The handle of a pair of sterile scissors is resting 5 cm (2 in) from the field's edge.
The Correct Answer is B
Rationale:
A. Allowing sterile forceps to rest in a container of sterile does not affect the sterility of the field.
B. Pouring sterile solution with the bottle held over the field is an inappropriate technique since it breaches the sterility of the field.
C. Placing unnecessary sterile items on the field is not ideal, but it does not indicate contamination of the surgical field.
D. The handle of a pair of sterile scissors resting 5 cm (2 in) from the field's edge does not indicate contamination of the surgical field. The scissors should be placed within easy reach of the nurse but should not touch non-sterile items.

Correct Answer is ["12.5"]
Explanation
To calculate the dose of ampicillin for a school-age child who weighs 55 lb, follow these steps: Convert the weight from pounds to kilograms:
55 lb × 1 kg/2.2 lb = 25 kg
Calculate the total daily dose of ampicillin:
50 mg/kg/day × 25 kg = 1250 mg/day
Divide the total daily dose by the number of doses per day:
1250 mg/day ÷ 4 doses/day = 312.5 mg/dose
Convert the dose from milligrams to milliliters using the concentration of the oral suspension:
312.5 mg/dose ÷ 125 mg/5 mL = 12.5 mL/dose
So, the nurse should administer approximately 12.5 mL of ampicillin oral suspension with each dose.
