Which of the following symptoms indicate bone marrow suppression due to chemotherapy?

The correct choice identifies symptoms associated with bone marrow suppression resulting from chemotherapy. Fatigue and pallor are common indicators of anemia, which often occurs due to reduced red blood cell production in the bone marrow. This not only leads to decreased oxygen delivery throughout the body, causing fatigue, but also contributes to a pale appearance due to lower hemoglobin levels.

Additionally, the mention of a risk for blood clots reflects potential complications stemming from low platelet counts, which are also a consequence of bone marrow suppression. Chemotherapy can adversely affect the production of these blood cells, leading to a condition called thrombocytopenia, where the body has difficulty forming clots, increasing the risk of bleeding and clotting instabilities.

In contrast, the other options listed do not directly correlate with the characteristic effects of bone marrow suppression caused by chemotherapy. The presence of activity intolerance, infection, and weight gain points more towards physical debilitation and metabolic changes rather than specific blood cell deficiencies. Similarly, pallor, pain, and nausea may arise from various conditions but do not narrowly signify bone marrow suppression. Lastly, symptoms like fever, chills, and respiratory issues often indicate infections or inflammation rather than the direct impacts of bone marrow failure. Thus, option A effectively captures the symptoms indicative
