Final answer:
To calculate the IBW for a 6'3'' male patient, the Devine formula is used, resulting in an IBW of 84.5 kg. The closest available answer is 81.81 kg, which is slightly less than the calculated IBW.
Step-by-step explanation:
The question involves the calculation of Ideal Body Weight (IBW), which is a medical estimation used to evaluate whether a person has a healthy body weight based on their height. To calculate IBW for a 6'3'' (75 inches or 190.5 cm) male patient in respiratory distress, we can use the Devine formula which is 50 kg + 2.3 kg for each inch over 5 feet. In this case:
- For a 6'3'' male: IBW = 50 kg + 2.3 kg/inch x (75 inches - 60 inches)
- IBW = 50 kg + 2.3 kg/inch x 15 inches
- IBW = 50 kg + 34.5 kg
- IBW = 84.5 kg
The closest answer to this calculation is b) 81.81 kg, though it is slightly less than the calculated IBW of 84.5 kg. It's important to note that this is an estimation and actual ideal weight may vary based on different factors such as body composition.
