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 A
Explanation
Choice A reason:
The statement “Provide bedtime rituals” is correct. Establishing a consistent bedtime routine can help toddlers feel more secure and relaxed, which can promote better sleep. Bedtime rituals might include reading a story, singing a lullaby, or having a warm bath before bed. These activities signal to the child that it is time to wind down and prepare for sleep.
Choice B reason:
The statement “Encourage play exercises in the evening” is incorrect. While physical activity is important for overall health, engaging in stimulating play exercises right before bedtime can make it harder for toddlers to settle down and fall asleep. It is better to encourage quiet, calming activities in the evening.
Choice C reason:
The statement “Explain the source of the toddler’s fears” is not the most effective approach for promoting sleep. While addressing fears is important, the explanation alone may not be sufficient to help the toddler feel secure enough to sleep. Providing comfort and reassurance through bedtime rituals is more effective in creating a sense of safety.
Choice D reason:
The statement “Turn off the room light” is partially correct but not the best standalone solution. While a dark environment can promote sleep, some toddlers may feel more secure with a nightlight. The focus should be on creating a calming and comfortable sleep environment, which includes but is not limited to adjusting the lighting.
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.
