Questions: Question 75 (1 point) Using the following patient information, calculate net filtati (NFP): BCOP = 35 mmHg and CHP = 45 mmHg 60 mmHg 10 mmHg -60 mmHg -10 mmHg

To calculate the Net Filtration Pressure (NFP), we use the following formula:

\[ \text{NFP} = \text{CHP} - \text{BCOP} \]

Where:

• CHP (Capillary Hydrostatic Pressure) is the pressure exerted by the blood against the capillary walls, which is given as 45 mmHg.
• BCOP (Blood Colloid Osmotic Pressure) is the pressure exerted by plasma proteins that tends to pull water into the circulatory system, which is given as 35 mmHg.

Substituting the given values into the formula:

\[ \text{NFP} = 45 \text{ mmHg} - 35 \text{ mmHg} \] \[ \text{NFP} = 10 \text{ mmHg} \]

Therefore, the answer is:

The answer is the second one: 10 mmHg.

Explanation for each option:

• 60 mmHg: Incorrect. This value does not match the calculation based on the given pressures.
• 10 mmHg: Correct. This is the result of the calculation using the provided CHP and BCOP values.
• -60 mmHg: Incorrect. This value is not relevant to the given pressures and the formula used.
• -10 mmHg: Incorrect. This would imply a negative net filtration pressure, which is not the case with the given values.

In summary, the correct net filtration pressure (NFP) based on the provided patient information is 10 mmHg.
