A nurse caring for a patient who suffered a severe sprain and has an order for a cold pack application to the injured area would prevent patient injury by:.

Choice A rationale:

Some older adults may indeed have concerns about taking pain medication, but this is not a primary reason for their hesitance to express pain. The fear of taking medication is not a universal characteristic of older adults.

Choice B rationale:

While older adults may be reluctant to bother nursing staff, this is not the primary reason for their reluctance to express pain. It is a consideration but not the main factor.

Choice C rationale:

The unawareness of discomfort is not a common reason for older adults to avoid expressing pain. Most older adults are aware of their discomfort but may not express it for other reasons.

Choice D rationale:

Older adults may have been culturally trained not to complain about pain or discomfort. In some cultures, stoicism and not burdening others with one's pain are highly valued. This cultural training can lead older adults to underreport their pain.

Choice E rationale:

Believing pain is a natural consequence of aging is a misconception, but it is not the primary reason why older adults may not express their pain. They may believe this, but cultural and societal factors have a more significant impact.

Choice A rationale:

Sleep influences memory. During the different stages of sleep, particularly during deep sleep (slow-wave sleep and rapid eye movement sleep), the consolidation of memories occurs. This means that sleep plays a critical role in memory function.

Choice B rationale:

Sleep influences mood. A lack of sleep or disrupted sleep patterns can lead to mood disturbances, including irritability, anxiety, and depression. Adequate sleep is essential for maintaining a stable and positive mood.

Choice C rationale:

Sleep influences cognitive function. Sleep is crucial for cognitive processes such as attention, problem-solving, and decision-making. Sleep deprivation can impair cognitive function, leading to reduced alertness and cognitive performance.

Choice D rationale:

Sleep influences the secretion of various hormones. Sleep plays a significant role in regulating hormones such as growth hormone, cortisol, and melatonin. Disruptions in sleep can lead to imbalances in these hormones, affecting various physiological processes.

Choice E rationale:

Sleep influences immune function. Adequate sleep is essential for a healthy immune system. During sleep, the immune system is actively engaged in repairing and protecting the body. Sleep deprivation can weaken the immune response, making individuals more susceptible to infections.

Choice F rationale:

Sleep influences body temperature. The body's core temperature fluctuates during the sleep-wake cycle, with the lowest point typically occurring during the night when we are asleep. This temperature regulation is essential for sleep quality and overall health.

Choice G rationale:

Sleep influences renal function. Sleep has an impact on various physiological processes, including renal function. The kidneys play a role in regulating blood pressure and electrolyte balance, which can be influenced by sleep patterns.
