A nurse is preparing to administer clindamycin by intermittent IV bolus over 30 minutes to a client who has a staphylococcal infection. Available is 300 mg clindamycin premixed in 50 mL 0.9% sodium chloride (NaCl). The nurse should set the IV pump to deliver how many mL/hr?
(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 ["100"]
Step 1: Determine the total volume to be infused.
- Total volume = 50 mL
- Result: 50 mL
Step 2: Determine the total time for infusion in hours.
- Total time = 30 minutes
- Convert minutes to hours: 30 minutes ÷ 60 minutes/hour = 0.5 hours
- Result: 0.5 hours
Step 3: Calculate the flow rate in mL/hr.
- Flow rate (mL/hr) = Total volume (mL) ÷ Total time (hours)
- Flow rate (mL/hr) = 50 mL ÷ 0.5 hours
- Result: 50 ÷ 0.5 = 100
Final Answer: The nurse should set the IV pump to deliver 100 mL/hr.

Correct Answer is D
Explanation
Choice A reason: Implement a resolution
Implementing a resolution without first understanding the root cause of the conflict can lead to ineffective solutions and may not address the underlying issues. It is essential to identify the problem first to ensure that any resolution is appropriate and effective.
Choice B reason: Evaluate the results
Evaluating the results is an important step in the conflict resolution process, but it comes after implementing a solution. Before any evaluation can take place, the problem must be identified, and a resolution must be implemented. Therefore, this step is not the first action to take.
Choice C reason: Brainstorm solutions
Brainstorming solutions is a critical part of resolving conflicts, but it should occur after the problem has been clearly identified. Without a clear understanding of the problem, brainstorming may not yield effective solutions. Identifying the problem ensures that the brainstorming session is focused and productive.
Choice D reason: Identify the problem
Identifying the problem is the first and most crucial step in resolving any conflict. Understanding the root cause of the conflict between the pharmacy and the staff nurses will provide a clear direction for developing effective solutions. This step involves gathering information, listening to all parties involved, and pinpointing the specific issues that need to be addressed.
Correct Answer is A
Explanation
Choice A reason: 90 bpm is the threshold below which the nurse should withhold digoxin for a 6-month-old infant. Digoxin can slow the heart rate, and administering it when the heart rate is already low can increase the risk of bradycardia, a serious heart rhythm disturbance.
Choice B reason: 100 bpm is above the threshold for withholding digoxin in a 6-month-old infant. While it is important to monitor the heart rate, digoxin can be safely administered if the apical heart rate is above 90 bpm.
Choice C reason: 110 bpm is also above the threshold for withholding digoxin. This heart rate indicates that the infant’s heart rate is within a safe range for administering the medication.
Choice D reason: 120 bpm is well above the threshold for withholding digoxin. This heart rate is considered safe for administering the medication, as it indicates the heart rate is not too low.
