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: Taking aspirin while on prednisone can increase the risk of gastrointestinal bleeding. Prednisone, a corticosteroid, can cause stomach irritation, and combining it with aspirin, a nonsteroidal anti-inflammatory drug (NSAID), can exacerbate this effect. Therefore, clients should avoid taking aspirin for minor aches and pains while on prednisone.
Choice B reason: A sore throat is not a common side effect of prednisone. Prednisone can suppress the immune system, making clients more susceptible to infections, but it does not typically cause a sore throat within the first week of use. If a client experiences a sore throat, they should contact their healthcare provider as it may indicate an infection.
Choice C reason: Clients on prednisone should avoid live vaccines, such as the flu vaccine, within one week of starting the medication. Prednisone can weaken the immune system, reducing the effectiveness of the vaccine and increasing the risk of developing the illness the vaccine is meant to prevent. It is generally recommended to consult with a healthcare provider before receiving any vaccines while on prednisone.
Choice D reason: Prednisone can cause potassium loss, leading to hypokalemia. Eating more bananas, which are high in potassium, can help counteract this effect and maintain normal potassium levels. Normal potassium levels range from 3.5 to 5.0 mEq/L. Therefore, clients should increase their intake of potassium-rich foods like bananas while taking prednisone.
Correct Answer is C
Explanation
Choice A reason: You sound overwhelmed. Let’s talk about this some more. This response acknowledges the mother’s feelings and opens the door for further discussion. However, it does not directly address her specific concerns about physical activities. While it is empathetic, it lacks the focus needed to explore her worries about her son’s participation in school activities.
Choice B reason: I agree. His well-being is the most important. This response validates the mother’s concern but may inadvertently reinforce her fears without providing a balanced perspective. It does not encourage a discussion about the benefits of physical activity for children with diabetes or how to manage his condition safely during such activities.
Choice C reason: Tell me more about how you are feeling about your son’s activities. This response is the most appropriate as it invites the mother to express her specific concerns and feelings. It shows empathy and a willingness to understand her perspective, which can lead to a more productive conversation about managing her son’s diabetes while allowing him to participate in physical activities.
Choice D reason: You might want to use tutors to home-school him. This response suggests an alternative that may not be necessary or beneficial. Home-schooling might isolate the child and prevent him from enjoying social interactions and physical activities that are important for his overall development. It does not address the mother’s concerns directly and may not be the best solution.
