The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

Problem 38<\/strong><\/h3>\n\n\n\n

Order:<\/strong> Kefzol 2 g IVPB diluted in 50 mL D5W to infuse in 15 min by an electronic infusion pump.
Flow rate:<\/strong> ___ mL\/h<\/p>\n\n\n\n

Solution:<\/strong><\/p>\n\n\n\n

Convert 15 minutes to hours:
15 \u00f7 60 = 0.25 hours<\/p>\n\n\n\n

Flow rate = Total volume \u00f7 Time
Flow rate = 50 mL \u00f7 0.25 h = 200 mL\/h<\/strong><\/p>\n\n\n\n

\n\n\n\n

Problem 39<\/strong><\/h3>\n\n\n\n

Order:<\/strong> 1,200 mL D5W at 27 gtt\/min
Drop factor:<\/strong> 15 gtt\/mL
Start time:<\/strong> 1600<\/p>\n\n\n\n

Step 1: Calculate total infusion time<\/strong>
Total volume (in mL) = 1,200 mL
Drop rate (gtt\/min) = 27 gtt\/min
Drop factor = 15 gtt\/mL<\/p>\n\n\n\n

First, calculate total drops:
1,200 mL \u00d7 15 gtt\/mL = 18,000 gtt<\/p>\n\n\n\n

Time in minutes = Total drops \u00f7 gtt\/min
Time = 18,000 \u00f7 27 = 666.67 minutes<\/p>\n\n\n\n

Convert to hours and minutes:
666.67 \u00f7 60 = 11 hours and 6.67 minutes \u2248 11 hours and 7 minutes<\/strong><\/p>\n\n\n\n

Completion time:<\/strong>
1600 + 11h 7min = 0310 (next day)<\/strong><\/p>\n\n\n\n

\n\n\n\n

Problem 40<\/strong><\/h3>\n\n\n\n

Order:<\/strong> Lactated Ringer\u2019s 1,000 mL IV at 25 gtt\/min
Drop factor:<\/strong> 10 gtt\/mL<\/p>\n\n\n\n

Total drops = 1,000 mL \u00d7 10 gtt\/mL = 10,000 gtt
Time in minutes = 10,000 \u00f7 25 = 400 minutes
Convert to hours and minutes:
400 \u00f7 60 = 6 hours and 40 minutes<\/p>\n\n\n\n

Infusion time:<\/strong> 6 hours and 40 minutes<\/strong><\/p>\n\n\n\n

\n\n\n\n

Problem 41<\/strong><\/h3>\n\n\n\n

Order:<\/strong> 0.9% sodium chloride IV at 65 mL\/h for 4 hours<\/p>\n\n\n\n

Volume = Rate \u00d7 Time
Volume = 65 mL\/h \u00d7 4 h = 260 mL<\/strong><\/p>\n\n\n\n

    Explanation <\/h3>\n\n\n\n

    In intravenous (IV) therapy, accurate calculations of infusion rates and volumes are essential to ensure patient safety and proper medication delivery. Each problem in this set focuses on a different skill within IV fluid calculations.<\/p>\n\n\n\n

    For problem 38, the use of an electronic infusion pump requires a flow rate in milliliters per hour. Given a 50 mL solution over 15 minutes, we convert 15 minutes into hours by dividing by 60, then use the formula: flow rate equals volume divided by time. This ensures that the electronic pump delivers the correct volume per hour.<\/p>\n\n\n\n

    Problem 39 focuses on calculating infusion time and completion time when given a specific drop rate. Here, the nurse uses a manual drip system, which involves knowing the drop factor and total volume. The formula used is: total drops divided by the drop rate gives the infusion time in minutes. That value is then converted to hours and added to the start time for completion.<\/p>\n\n\n\n

    Problem 40 is similar but uses a different drop factor. Here, determining how long it will take for a known volume to infuse at a specified rate is essential. Again, multiplying volume by the drop factor gives total drops, and dividing by the drop rate gives total time.<\/p>\n\n\n\n

    Lastly, problem 41 involves a simple multiplication of the hourly rate by the duration to calculate total volume. This calculation is crucial when setting up IV bags to avoid under- or overdosing the patient.<\/p>\n\n\n\n

    Mastery of these calculations helps ensure that patients receive their medications and fluids at the proper rate and volume, avoiding complications such as fluid overload or inadequate treatment.<\/p>\n\n\n\n
