A nurse is providing teaching for a client who has binge-eating disorder and is morbidly obese. The client has been prescribed orlistat. Which of the following statements indicates to the nurse that the client understands the teaching?

A. "My child must be free from this before returning to school": While it's important for the child to be treated and free from head lice before returning to school, this statement alone doesn't address the comprehensive measures needed to eradicate pediculosis capitis. It focuses only on the child's return to school without considering other aspects of treatment and prevention.
B. "Toys that can't be dry cleaned or washed must be thrown out": Throwing out toys that can't be dry cleaned or washed is an extreme measure and unnecessary for managing pediculosis capitis. While cleaning items that come into contact with the child's head is important, it's not necessary to dispose of toys unless they cannot be effectively cleaned.
C. "All recently used clothing, bedding, and towels must be washed in hot water": This statement indicates a thorough understanding of the teaching. Washing recently used clothing, bedding, and towels in hot water is an essential step in eliminating head lice and preventing reinfestation. Hot water helps kill lice and their eggs, reducing the risk of transmission.
D. "I will treat all the family members to be on the safe side": Treating all family members is a prudent measure to prevent the spread of head lice within the household. However, this statement alone doesn't address other important aspects of treatment and prevention, such as washing bedding and clothing. While treating family members is important, it's only one part of a comprehensive approach to managing pediculosis capitis.

Here's how we can find the desired flow rate:

1. Total volume to infuse (in minutes):
   • We need to convert the infusion time from hours to minutes.
   • Time (minutes) = Time (hours) x 60 minutes/hour
   • Time (minutes) = 2 hours x 60 minutes/hour
   • Time (minutes) = 120 minutes
2. Total volume to infuse (in mL):
   • Given volume = 250 mL
3. Drop factor (gtts/mL):
   • Given drop factor = 15 gtts/mL
4. Flow rate (gtts/minute):
   • Flow rate = Total volume (mL) / Time (minutes) x Drop factor (gtts/mL)
   • Flow rate = 250 mL / 120 minutes x 15 gtts/mL

To simplify the calculation, we can divide all values by 5 (as long as we perform the division on both sides of the equation, the answer won't change):

• Flow rate = (250 mL / 5) / (120 minutes / 5) x (15 gtts/mL / 5)
• Flow rate = 50 mL / 24 minutes x 3 gtts/mL
• Flow rate = 2.0833... gtts/minute (round to nearest whole number)

1. Rounded flow rate (gtts/minute):
   • Flow rate = 2 gtts/minute

Therefore, the nurse should adjust the flow rate to deliver approximately 2 gtts/minute.
