In caring for a client with exacerbations of multiple sclerosis, the nurse recognizes that the exacerbations result in which pathologic change?

Choice A reason: Acute lymphoblastic leukemia (ALL) is an aggressive malignancy of lymphoid cells, often achieving complete remission with intensive chemotherapy, especially in children. Suppression without remission is not typical, as ALL responds well to treatment, targeting rapidly dividing blast cells. CLL, a slower-progressing disease, better fits the description of suppression without complete cure.

Choice B reason: Chronic lymphocytic leukemia (CLL) is a low-grade malignancy of mature B-lymphocytes, often managed with chemotherapy to suppress disease progression rather than achieve complete remission. CLL’s indolent nature means it can be controlled, but residual disease persists due to slow cell turnover, aligning with the question’s description of suppression.

Choice C reason: Acute myelogenous leukemia (AML) is an aggressive malignancy of myeloid cells, requiring intensive chemotherapy or stem cell transplant for potential remission. Suppression without remission is less common, as AML treatment aims for complete response. CLL’s chronic nature makes it more likely to result in disease control rather than cure.

Choice D reason: Hairy-cell leukemia is a rare, indolent B-cell malignancy highly responsive to purine analogs, often achieving long-term remission or near-cure. Suppression without remission is not characteristic, as treatment typically yields durable responses. CLL’s partial response to chemotherapy better matches the scenario of ongoing disease suppression.

Choice A reason: Acute asthma exacerbations involve bronchospasms, airway edema, and excessive mucus production, narrowing airways and causing wheezing and dyspnea. These reversible inflammatory responses are triggered by allergens or irritants, aligning with asthma’s pathophysiology. This accurately describes the acute obstructive process, per respiratory medicine evidence.

Choice B reason: Thick exudates blocking airways are characteristic of conditions like pneumonia, not asthma. Asthma involves bronchospasms, edema, and mucus, not dense exudate. This choice misrepresents asthma’s acute inflammatory process, which is reversible and driven by smooth muscle contraction and mucosal swelling, making it incorrect.

Choice C reason: Chronic inflammation of the bronchi/trachea from infection suggests chronic bronchitis or tracheitis, not asthma. Asthma exacerbations are acute, triggered by non-infectious stimuli, causing spasms and edema. This chronic infectious process does not align with asthma’s reversible, allergic pathophysiology, making it an incorrect description.

Choice D reason: Reduced lung surface area from alveolar damage occurs in emphysema, not asthma. Asthma affects airways via spasms and inflammation, not alveoli. This choice describes a different obstructive disease, unrelated to asthma’s acute, reversible airway pathology, making it incorrect for an exacerbation’s pathophysiological mechanism.
