Question

acid base balance is an important aspect of homeostasis. the nurse is measuring the ph of several items. the nurse is instructing the client to stay away from alkaline food sources. which item should the nurse suggest that the client avoid because of its alkaline nature

Answer 1

For proper physiological functioning, the body maintains a tight acid-base balance, using buffering systems to stabilize blood pH between 7.35 and 7.45. To avoid alkaline foods, one should stay clear of items like baking soda and certain high pH foods such as certain fruits and vegetables.

Step-by-step explanation:

Acid-base balance is crucial for the proper physiological functioning of the body, which depends on a finely-tuned balance between the concentrations of acids and bases in the blood. The pH scale is used to measure this balance, with a normal blood pH ranging from 7.35 to 7.45. The body utilizes buffering systems, which are combinations of weak acids and weak bases that prevent drastic changes in pH by absorbing excess hydrogen (H+) or hydroxide (OH-) ions, thereby maintaining homeostasis.

To help a client stay away from alkaline food sources, the nurse should advise them to avoid foods known for having a high pH. For example, baking soda, which is highly alkaline with a pH value of around 9.0, should be avoided. Alkaline diets often include certain fruits, vegetables, nuts, and legumes; the nurse should provide specific guidance on which of these foods are more alkaline and should be avoided based on the client's health needs.
