The correct answer and explanation is:
Let’s go step by step and solve each question.
Weight Conversions
To convert between pounds (lb), ounces (oz), and kilograms (kg), use the following conversions:
- 1 lb = 0.4536 kg
- 1 oz = 0.02835 kg
- 1 kg = 2.2046 lb
32. Convert 7.6 kg to lb
7.6×2.2046=16.75≈16.8 lb7.6 \times 2.2046 = 16.75 \approx 16.8 \text{ lb}
33. Convert 18 lb 12 oz to kg
- Convert pounds: 18×0.4536=8.165 kg18 \times 0.4536 = 8.165 \text{ kg}
- Convert ounces: 12×0.02835=0.3402 kg12 \times 0.02835 = 0.3402 \text{ kg}
- Add both values: 8.165+0.3402=8.5052≈8.5 kg8.165 + 0.3402 = 8.5052 \approx 8.5 \text{ kg}
34. Convert 41 lb 2 oz to kg
- Convert pounds: 41×0.4536=18.5976 kg41 \times 0.4536 = 18.5976 \text{ kg}
- Convert ounces: 2×0.02835=0.0567 kg2 \times 0.02835 = 0.0567 \text{ kg}
- Add both values: 18.5976+0.0567=18.6543≈18.7 kg18.5976 + 0.0567 = 18.6543 \approx 18.7 \text{ kg}
35. Convert 14 lb 4 oz to kg
- Convert pounds: 14×0.4536=6.3504 kg14 \times 0.4536 = 6.3504 \text{ kg}
- Convert ounces: 4×0.02835=0.1134 kg4 \times 0.02835 = 0.1134 \text{ kg}
- Add both values: 6.3504+0.1134=6.4638≈6.5 kg6.3504 + 0.1134 = 6.4638 \approx 6.5 \text{ kg}
Length Conversions
36. Convert 34 mm to cm
34÷10=3.4 cm34 \div 10 = 3.4 \text{ cm}
37. Convert 16.2 in to cm
16.2×2.54=41.15 cm16.2 \times 2.54 = 41.15 \text{ cm}
IV Time Calculation
38. An IV started at 3:10 AM and runs for 12 hours 30 minutes
- Add 12 hours: 3:10 AM+12 hours=3:10 PM3:10 \text{ AM} + 12 \text{ hours} = 3:10 \text{ PM}
- Add 30 minutes: 3:10 PM+30 minutes=3:40 PM3:10 \text{ PM} + 30 \text{ minutes} = 3:40 \text{ PM}
Completion Time: 3:40 PM
Explanation (300 Words)
Conversions between different units of weight, length, and time are crucial in daily life, particularly in medical, scientific, and engineering fields. Understanding how to convert units ensures accuracy in calculations, which can be critical in contexts like medication dosages, fluid administration, and scientific measurements.
In weight conversion, knowing that 1 pound equals 0.4536 kilograms and 1 ounce equals 0.02835 kilograms allows for accurate transformations. When converting pounds and ounces to kilograms, it is necessary to compute each part separately and then sum them up. For example, 18 lb 12 oz is first broken down into kilograms for pounds and ounces, then added together to get an accurate value. Similarly, for 14 lb 4 oz, the same approach is used.
Length conversions also follow straightforward formulas. Since 1 mm = 0.1 cm, converting 34 mm to cm requires a simple division. For inches to centimeters, 1 inch equals 2.54 cm, meaning multiplication is needed. For example, 16.2 inches is multiplied by 2.54 to get an exact cm value.
Time calculations, such as IV completion times, require careful addition of hours and minutes. When an IV starts at 3:10 AM and runs for 12 hours 30 minutes, adding 12 hours results in 3:10 PM, and adding 30 minutes gives 3:40 PM. Precise time calculations are crucial in healthcare settings to avoid errors in patient care.
Overall, accurate unit conversions play a vital role in everyday activities, from cooking to medication administration, engineering, and beyond.
