A 55-year-old woman visits a popular eatery for lunch. She orders a cheese and bacon pizza with extra cheese and has about 3 large glasses of cola (ph value 3). On the way back home, she experiences heartburn and abdominal pain, and has difficulty breathing. She drinks a lot of water and has to consume milk of magnesia (pH value 10.5) before she feels comfortable again.
Classify the liquids that she has consumed as acidic or alkaline.
State the pH values of water and blood.
State what the patient can include and avoid in her diet on a regular basis to avoid these symptoms in the future.
5.2
At a prominent state hospital, a 45-year-old woman is receiving a 'combined modality' treatment for the initial stage of breast cancer. State the two aspects included in this treatment. State the methods by which a radiation oncologist can administer these therapies. Additionally, state four major differences between the two modes of treatment.

The Managing Director of a well-known company on Wall Street thrives on a diet of fruit jam, bread, pasta, and coffee. She exercises intermittently. One day she decides to go to her primary healthcare provider for a routine checkup. The healthcare provider recommends that she take the Benedict's test. Assume that the glucose levels of the patient are high.
State the results that the test would indicate (specify the color of the solution).
State the composition and the properties of the ketohexose derived from fruit jam.
Describe the manner in which ketohexose acts as a reducing sugar in the test.
10.2

A 55-year-old woman visits a popular eatery for lunch. She orders a cheese and bacon pizza with extra cheese and has about 3 large glasses of cola (ph value 3). On the way back home, she experiences heartburn and abdominal pain, and has difficulty breathing. She drinks a lot of water and has to consume milk of magnesia (pH value 10.5) before she feels comfortable again.
a) Classify the liquids that she has consumed as acidic or alkaline.
b) State the pH values of water and blood.
c) State what the patient can include and avoid in her diet on a regular basis to avoid these symptoms in the future.
4.2a) pH value 3 is acidic
b) Absolutely pure water has a pH of 7. In reality, some amount of CO2 is dissolved in water, forming carbonic acid and lowering the pH slightly, but this can vary, so it is useless to try and state exactly. Blood pH is around 7.4
c) Avoiding acidic foods in the future and including more dairy products and water instead of soda may help her avoid those symptoms.
