After an assessment, the nurse realizes that a client demonstrates cognitive responses to stress. What behaviors did the client demonstrate for the nurse to make this clinical determination?

A. Excessive thirst and urination:
Excessive thirst and urination are symptoms typically associated with hyperglycemia, where there is a high level of glucose in the blood, often related to diabetes. When TPN is stopped suddenly, the concern is more about hypoglycemia due to the abrupt lack of glucose infusion, not hyperglycemia.

B. Shakiness and diaphoresis:
When TPN is suddenly interrupted, the continuous supply of glucose that the patient relies on is abruptly halted. This can lead to a rapid drop in blood sugar levels, causing hypoglycemia. Symptoms of hypoglycemia include shakiness, diaphoresis (sweating), confusion, and even loss of consciousness if not promptly addressed. Monitoring for shakiness and diaphoresis is crucial in this scenario to prevent severe hypoglycemia.

C. Hypertension and crackles:
These symptoms are typically indicative of fluid overload or heart failure. While TPN can contribute to fluid overload if not managed properly, the immediate concern with the cessation of TPN is the lack of glucose and potential hypoglycemia, not fluid overload.

D. Fever and chills:
Fever and chills are generally signs of an infection, such as sepsis. While infections can be a complication of TPN due to the intravenous route of administration, they are not directly related to the sudden stopping of TPN. The primary concern when TPN stops unexpectedly is the risk of hypoglycemia due to the cessation of glucose infusion.

A) Bright light: Exposure to bright light, especially in the evening or at night, can interfere with the body's production of melatonin, a hormone that regulates the sleep-wake cycle. Bright light exposure can disrupt circadian rhythms, making it more challenging to fall asleep and stay asleep.

B) Drinking caffeinated beverages in the evening: Caffeine is a stimulant that can interfere with sleep by blocking the effects of adenosine, a neurotransmitter that promotes sleepiness. Consuming caffeinated beverages in the evening can delay the onset of sleep and reduce overall sleep duration.

C) A 20-minute nap during the day: While short naps can be beneficial for some individuals, especially if they are sleep-deprived, napping for too long or too late in the day can disrupt the body's natural sleep-wake cycle. Short naps can be refreshing, but longer or late-day naps can make it harder to fall asleep at night.

D) Emotional stress: Stress and anxiety can trigger the body's "fight or flight" response, leading to increased alertness and difficulty relaxing or falling asleep. Chronic stress can disrupt the sleep-wake cycle, leading to difficulty initiating or maintaining sleep and resulting in poor sleep quality.

E) A regular bedtime schedule: Having a consistent bedtime schedule can actually help regulate the sleep-wake cycle by reinforcing the body's internal clock. Going to bed and waking up at the same time each day, even on weekends, can help improve sleep quality and make it easier to fall asleep and wake up naturally.
