Since blood production requires iron, you should eat iron-rich foods for two weeks before your appointment. This will help you have strong blood for donation and help you better recuperate after your donation. Iron-rich foods include spinach, whole grains, fish, poultry, beans, organ meat, eggs, and beef.
To calculate the change in temperature, subtract the initial temperature from the final temperature. Example: 84.2 degree Fahrenheit - 41 degrees Fahrenheit = 43.2 degrees Fahrenheit. The temperature from morning to afternoon changed by 43.2 degrees Fahrenheit.
Determine the temperature by reading the scale on the thermometer at eye level. Read the temperature by using all certaindigits and one uncertaindigit. Certaindigits are determined from the calibration marks on the thermometer. Theuncertaindigit (the last digit of the reading) is estimated.
