A client receives a prescription for 500 mL of lactated Ringer's IV to be infused over 4 hours. The IV administration set delivers 20 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["42"]
Flow rate (gtt/min) = (Total volume× Drop factor)/Total time
= (500×20)/240
= 1000/240
= 41.67, round off to the nearest whole number
= 42
Thus, the nurse should regulate the infusion at 42 gtt/min.

Correct Answer is ["3.8"]
Explanation
3.8 mL per dose
Calculation:
- Convert 35 pounds to kilograms: 35÷2.2=15.9kg
- Determine the correct dosage:
- 15 to 23 kg → 45 mg BID
- Calculate the volume to administer: 45mg÷12mg/mL=3.75mL
- Round to the nearest tenth:
- 3.75 ≈ 3.8 mL
Thus, the nurse should administer 3.8 mL per dose.
Correct Answer is A
Explanation
A. Staphylococcus aureus abscess around a hair follicle. A furuncle, or boil, is a deep infection of a hair follicle caused by Staphylococcus aureus. It presents as a painful, pus-filled nodule due to bacterial invasion and inflammation. Poor hygiene, friction, or immune suppression can increase susceptibility.
B. Insect or spider bite that becomes infected. While insect bites can introduce bacteria into the skin, they do not directly cause furuncles. Secondary infection may occur, but furuncles specifically arise from infected hair follicles, not bites.
C. Sexual contact with an infected partner. Furuncles are not sexually transmitted infections. While skin-to-skin contact can spread Staphylococcus aureus, furuncles are not a direct result of sexual activity.
D. Inadequate blood supply to the area. Poor circulation can impair wound healing and increase infection risk, but furuncles result from bacterial infection of a hair follicle rather than ischemia.
