1. a patient receives 3 pints of blood via a transfusion. how much blood was transfused in milliliters?

a. 300 ml
b. 500 ml
c. 900 ml
d. 1500 ml

Explanation:

Step1: Convert Fahrenheit to Celsius

The formula to convert Fahrenheit ($F$) to Celsius ($C$) is $C=\frac{5}{9}(F - 32)$. For $F = 46.4^{\circ}F$, we have $C=\frac{5}{9}(46.4 - 32)=\frac{5}{9}\times14.4 = 8^{\circ}C$.

Step2: Convert Celsius to Fahrenheit

The formula to convert Celsius ($C$) to Fahrenheit ($F$) is $F=\frac{9}{5}C+32$. For $C = 39.2^{\circ}C$, we have $F=\frac{9}{5}\times39.2+32=70.56 + 32=102.56\approx102.6^{\circ}F$.

Step3: Analyze the closest temperature

For $C = 100^{\circ}C$, converting to Fahrenheit: $F=\frac{9}{5}\times100+32=180 + 32=212^{\circ}F$. Among the options, $213^{\circ}F$ is closest.

Step4: Convert pints to milliliters

Since 1 pint is approximately 500 ml, for 3 pints, the volume in milliliters is $3\times500 = 1500$ ml.

Answer:

1. B. $8^{\circ}C$
2. B. $102.6^{\circ}F$
3. D. $213^{\circ}F$
4. D. $1500$ ml
