The nurse receives a prescription for ciprofloxacin 400 mg intravenously (IV) every 12 hours to be infused over an hour. The IV bag contains ciprofloxacin 400 mg in dextrose 5% in water (D5W) 200 mL. The nurse should program the infusion pump to deliver how many mL/hr? (Enter numerical value only.)

Choice A reason: Determining when the last dose was administered is important to ensure safe and effective pain management, but it is not the first action that the nurse should implement. The nurse should first assess the client's pain level and intensity before deciding on the appropriate dose and frequency of pain medication.

Choice B reason: Encouraging the client to use diversional thoughts to manage pain is a non-pharmacological intervention that can help reduce pain perception and anxiety, but it is not sufficient to address severe or acute pain. The nurse should first assess the client's pain level and intensity before suggesting any complementary or alternative therapies.

Choice C reason: Asking the client to rate the current level of pain using a pain scale is the first action that the nurse should implement, as it can help quantify and communicate the client's pain experience and guide the nurse's decision on pain medication. The nurse should use a valid and reliable pain scale that is appropriate for the client's age, cognitive ability, and language preference.

Choice D reason: Reviewing the history for a past use of recreational drugs is relevant to assess the client's risk of addiction or tolerance to pain medication, but it is not the first action that the nurse should implement. The nurse should first assess the client's pain level and intensity before considering any factors that may influence pain management.

Choice A reason: Encouraging an increase in oral intake is not necessary in this situation, as dark urine is not a sign of dehydration or fluid imbalance. Dark urine may be caused by certain foods, medications, or medical conditions, but it does not indicate a need for more fluids.

Choice B reason: Measuring the client's urinary output is not relevant to this situation, as dark urine is not a sign of urinary retention or obstruction. Urinary output may vary depending on fluid intake, activity level, or other factors, but it does not reflect urine color.

Choice C reason: Explaining that color change is normal is the appropriate action to take, as dark urine is a common and harmless side effect of carbidopa/levodopa, which is a combination drug used to treat Parkinson's disease by increasing dopamine levels in the brain. Carbidopa/levodopa can cause urine to turn brown, black, or red, but this does not affect the function or health of the kidneys or bladder.

Choice D reason: Obtaining a specimen for a urine culture is not necessary in this situation, as dark urine is not a sign of infection or inflammation. A urine culture may be indicated if the client has symptoms such as fever, pain, burning, frequency, or urgency, but it does not diagnose urine color
