A nurse is assisting with evaluating teaching with a client who reports insomnia. Which of the following client statements indicates an understanding of the teaching?

Choice A reason : The term "alert" is an objective finding in the nursing assessment. It refers to the client's level of consciousness and responsiveness to stimuli, which can be directly observed and measured by the nurse during the evaluation. Being alert is a state that is evident through the client's behavior, responses, and interactions.

Choice B reason : "Pacing" is an objective finding. It is a visible behavior that can be observed and documented by the nurse without the need for interpretation or reliance on what the client says. Pacing can be quantified by the number of times the client walks back and forth in a given period.

Choice C reason : "Anxiety" is a subjective finding because it is based on the client's personal feelings and cannot be directly observed or measured by the nurse. It is reported by the client and requires the nurse to rely on the client's expression of their emotional state.

Choice D reason : "Restless" is an objective finding. Restlessness can be observed as physical movements, such as the inability to stay still, fidgeting, or frequent changes in position. These are behaviors that the nurse can see and document.

Choice A reason : Drinking caffeinated beverages in the evening.Caffeine is a stimulant that can significantly disrupt the sleep-wake cycle. Consuming caffeinated beverages in the evening can lead to difficulty initiating sleep because caffeine blocks the action of adenosine, a chemical that promotes sleep. The effects of caffeine can last several hours, thus affecting the quality and duration of sleep.

Choice B reason : Emotional stress activates the body's stress response, causing the release of hormones like cortisol, which increases alertness and can delay the onset of sleep. Chronic stress can lead to a hyperarousal state, making it difficult to fall asleep and stay asleep.

Choice C reason : Bright light.Exposure to bright light, especially blue light from screens, can interfere with the production of melatonin, the hormone that signals the body to prepare for sleep. This can shift the circadian rhythm and disrupt the sleep-wake cycle, making it harder to fall asleep at the usual time.

Choice D reason : A short nap during the day, typically 20-30 minutes, can be beneficial and usually does not interfere with nighttime sleep. However, longer or later naps can make it more difficult to fall asleep at night.
