A nurse is caring for a 24-year-old client who has frequent premature atrial contractions seen on the cardiac monitor. The nurse understands that the client requires additional education when the client selects which of the following items for the breakfast tray?

A. Fluticasone is an inhaled corticosteroid used primarily for maintenance therapy in COPD and asthma. It helps reduce airway inflammation and prevent exacerbations but is not used for immediate relief of acute symptoms such as bronchospasm or sudden shortness of breath.
B. Fluticasone, like other corticosteroids delivered by inhalation, can increase the risk of oral thrush (candidiasis) due to its local immunosuppressive effects in the mouth. It's important for clients to monitor their oral cavity regularly for signs such as white patches or soreness. Including this instruction is crucial to detect thrush early so that appropriate treatment can be initiated if necessary.
C. Monitoring heart rate is not specifically necessary before each dose of fluticasone. Fluticasone is not known to cause significant cardiovascular effects such as changes in heart rate. Heart rate monitoring may be more relevant for medications that can affect cardiovascular function or in clients with pre- existing cardiac conditions.

D. Fluticasone should be used regularly as prescribed for maintenance therapy to control airway inflammation and prevent exacerbations in COPD. Skipping doses, even if symptoms are not present, can lead to inadequate control of the disease and potential worsening of symptoms over time.

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.
