Which phrase describes the function of a buffer?

Choice A rationale:

Buffers do not excrete weak acids; instead, they help regulate the pH of bodily fluids by preventing drastic changes in acidity or alkalinity.

Choice B rationale:

Buffers do not secrete hydrogen ions. In fact, buffers can either absorb or release hydrogen ions to maintain a stable pH.

Choice C rationale:

To convert strong acids to weak acids is the correct answer. Buffers are substances that can neutralize both acids and bases, helping to maintain a stable pH in a solution. They achieve this by accepting hydrogen ions from strong acids or donating hydrogen ions to strong bases, converting them into weaker acids or bases, respectively.

Choice D rationale:

Buffers do not convert ammonia to ammonium ions. This conversion is a part of the body's acid-base regulation system, but it is not the primary function of buffers.

Choice A rationale:

While leukemia treatment does have severe side effects, not all of them are permanent. It is essential for the patient to be aware of potential complications but also to understand that some side effects might be temporary and can be managed with appropriate care.

Choice B rationale:

Using the call light to ask for help when getting out of bed is essential for patients receiving chemotherapy, as their immune system might be compromised, making them prone to infections and injuries. However, this information is not specific to leukemia treatment but is a general safety measure for these patients.

Choice C rationale:

Patients undergoing chemotherapy for leukemia are at an increased risk of infections due to the suppression of the immune system. Preventive measures, such as good hygiene practices and early detection of signs of infection, are crucial in managing these patients. Educating the patient about infection prevention is essential for their safety during treatment.

Choice D rationale:

Feeling isolated can be a common emotional response to any chronic illness, including leukemia. However, it is not an unavoidable consequence, and providing emotional support and involving the patient in support groups can help mitigate these feelings. This statement does not provide essential information about managing leukemia treatment.
