Abstract:
Predictive biomarkers are revolutionizing decisions about colon cancer treatment. Knowing which biomarkers are altered provides valuable information about which treatment may be more effective. DNA mismatch repair and microsatellite instability testing may also identify families that could benefit from further genetic evaluation to determine if there is hereditary risk for colon cancer. Nurses need to be able to explain what these biomarkers mean and how they affect treatment decisions, as well as recommend genetic counseling and testing for hereditary risk when appropriate.

Memory is the retention of information or experiences over time, facilitated through three main processes: encoding, storage, and retrieval. Encoding is the process of inputting information into the memory system. For instance, when listening to a lecture, watching a play, reading a book, or having a conversation, the brain is actively encoding information. This initial stage involves transforming sensory input into a form that can be processed and stored by the brain. Various factors, such as...

Consciousness can be defined as the state of being aware of and able to think about one's existence, sensations, and surroundings. It encompasses two major components: awareness and arousal. Awareness pertains to the recognition of environmental stimuli and internal states. At the same time, arousal refers to the physiological readiness to engage with these stimuli, which varies significantly between states like sleep and wakefulness.

Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...
