A female client with multiple sclerosis is being treated with prednisone and the immunomodulator drug interferon B-1a to manage the condition. Which finding is the most important for the nurse to report to the provider?

A. A vegetarian diet typically does not directly contribute to bronchoconstriction. In fact, a diet rich in fruits and vegetables may provide antioxidants and anti-inflammatory compounds that can be beneficial for respiratory health. Therefore, this option is less likely to be a cause of the client's bronchoconstriction.
B. Rosuvastatin (and other statins) are generally well-tolerated, but some individuals may experience respiratory side effects, including cough or shortness of breath. However, bronchoconstriction as a direct side effect of statins is uncommon and typically not a primary concern unless there is a rare hypersensitivity reaction.
C. Propranolol is a non-selective beta-blocker that can lead to bronchoconstriction, particularly in individuals with asthma or other respiratory conditions. Beta-blockers can block beta-2 receptors in the lungs, potentially causing constriction of the airways and worsening of respiratory symptoms.
D. Acetaminophen (paracetamol) is generally considered safe and does not typically cause bronchoconstriction. It is a non-steroidal anti-inflammatory drug (NSAID) that works differently from medications like beta-blockers, which directly affect the airways.

A. Cancer cells typically lose their specialized functions and characteristics that normal cells have. This loss of differentiation is known as dedifferentiation, where cancer cells become less specialized and more primitive in nature. This allows them to proliferate rapidly and invade surrounding tissues.
B. Contact inhibition refers to the normal process where cells stop dividing when they come into contact with neighboring cells. In cancer cells, this mechanism is disrupted, leading to uncontrolled cell growth and proliferation. Cancer cells continue to divide and grow even when they are in close contact with other cells, which contributes to tumor formation and progression.
C. Cancer cells often acquire mutations that impair their ability to repair DNA damage effectively. This can lead to an accumulation of genetic mutations over time, which is a hallmark of cancer development. While some cancer cells may still have mechanisms to repair DNA damage, they are often less efficient compared to normal cells, leading to genomic instability and further mutation accumulation.
D. Normal cells follow a tightly regulated cell cycle with specific checkpoints that ensure orderly progression through phases such as G1, S, G2, and M phases. In contrast, cancer cells often have dysregulated cell cycle control. They may bypass checkpoints that normally control cell division, leading to uncontrolled proliferation and growth.
