A nurse weighed a client who is following a weight-loss plan. The scale shows that the client weighs 91 kg. What is the client’s weight in lb? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct answer and Explanation is:
To convert a weight from kilograms (kg) to pounds (lb), you can use the conversion factor that 1 kg is approximately equal to 2.20462 lb. This means that to find the weight in pounds, you can multiply the weight in kilograms by this conversion factor.
Given the client’s weight of 91 kg, the calculation is as follows:
[
\text{Weight in lb} = \text{Weight in kg} \times 2.20462
]
Substituting in the value:
[
\text{Weight in lb} = 91 \, \text{kg} \times 2.20462 \, \text{lb/kg}
]
Performing the multiplication:
[
\text{Weight in lb} = 91 \times 2.20462 \approx 200.61942 \, \text{lb}
]
To round this to the nearest whole number, we look at the decimal part. Since 0.61942 is greater than 0.5, we round up to 201.
Thus, the client’s weight in pounds is 201 lb.
Explanation
The conversion process from kilograms to pounds is essential in nursing practice, especially in the context of weight management and dietary planning. Health professionals often need to communicate weight effectively across different measurement systems, as kilograms are standard in many parts of the world while pounds are more common in the United States.
Understanding weight conversions allows nurses to provide accurate information regarding a client’s weight status, which is crucial for monitoring progress in weight-loss plans, evaluating dietary intake, and administering medications. For instance, many medications are dosed based on body weight, so an accurate measurement is vital for effective treatment.
In clinical settings, it’s also important to ensure the accuracy of scales and the consistency of measurement techniques to avoid discrepancies that could impact patient care. Rounding the final weight to the nearest whole number simplifies communication and documentation. By using a standard conversion factor, nurses can convert weights confidently and accurately, ensuring they support clients effectively in their health journeys.
