A nurse is preparing to infuse a 250-mL unit of packed RBCs over 2 hours. The drop factor of the manual IV tubing is 15 gtts/mL. The nurse should adjust the flow rate to deliver how many drops per minute?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["31"]
Step 1: Determine the total volume to be infused.
- Total volume = 250 mL
Step 2: Determine the total time for infusion in minutes.
- Total time = 2 hours
- Convert hours to minutes: 2 hours × 60 minutes/hour = 120 minutes
- Result: 120 minutes
Step 3: Determine the drop factor.
- Drop factor = 15 gtts/mL
Step 4: Calculate the flow rate in drops per minute.
- Flow rate (gtts/min) = (Total volume in mL × Drop factor) ÷ Total time in minutes
- Flow rate (gtts/min) = (250 mL × 15 gtts/mL) ÷ 120 minutes
- Result: (250 × 15) = 3750
- Result: 3750 ÷ 120 = 31.25
Step 5: Round the result to the nearest whole number.
- Rounded result: 31
Final Answer: The nurse should adjust the flow rate to deliver 31 drops per minute.

Correct Answer is D
Explanation
Choice A reason: I would be happy to do whatever I can to help you. While this response shows empathy and a willingness to help, it does not address the fact that shopping for the client is outside the nurse’s job description. It is important for the nurse to adhere to professional boundaries and find appropriate solutions within those limits.
Choice B reason: What I think you should do is wait for the days when you feel better and do your grocery shopping then. This response is not practical or supportive. It does not provide a solution for the client’s immediate needs and may come across as dismissive of her current difficulties.
Choice C reason: I won’t be able to shop for you today because I have to get home to my family. This response is honest but lacks empathy and does not offer any alternative solutions. It may leave the client feeling unsupported and frustrated.
Choice D reason: Let’s look at some other resources to solve this problem. This response is the most appropriate as it acknowledges the client’s needs and seeks to find a solution within the nurse’s professional boundaries. The nurse can help the client explore options such as grocery delivery services, community resources, or assistance from family and friends.
Correct Answer is B
Explanation
Choice A reason: Sometimes my child acts bossy with his friends is a common behavior in children as they navigate social interactions and develop leadership skills. While it may require some guidance on social skills, it is not typically a cause for medical concern.
Choice B reason: The teacher says my child has to squint to see the board is concerning because it indicates a potential vision problem. Squinting to see the board can be a sign of refractive errors such as myopia (nearsightedness) or astigmatism. Early detection and correction of vision problems are crucial for a child’s academic performance and overall development.
Choice C reason: My child has recently lost both front top teeth is a normal part of dental development. Children typically lose their primary (baby) teeth around the age of 6 to 7 years as their permanent teeth begin to erupt. This is a natural process and not a cause for concern.
Choice D reason: My child often cheats when we play board games can be a normal part of a child’s development as they learn about rules and fairness. While it may require parental guidance to teach honesty and fair play, it is not typically a medical concern.
