Sleep influences memory, mood, cognitive function, secretion of various hormones, immune function, body temperature, and renal function.
True
False
The Correct Answer is A
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.

Correct Answer is B
Explanation
Choice A rationale:
Placing electrodes on all four extremities is not the initial step in using a Transcutaneous Electrical Nerve Stimulator (TENS) unit. It may not be necessary for the specific pain management needs of the patient and can be uncomfortable or impractical.
Choice B rationale:
This is the correct initial step when starting TENS treatment. The nurse should adjust the settings to a level below the threshold at which the patient feels a tingling sensation. This ensures that the treatment is comfortable and safe for the patient. The goal is to provide pain relief, not to induce discomfort.
Choice C rationale:
Turning the unit on before attaching it to the patient is not advisable. It's essential to connect the electrodes to the patient first and then turn on the TENS unit. This sequence helps prevent accidental electrical stimulation before the device is properly set up.
Choice D rationale:
Applying conductive jelly to uncoated electrodes is a step in preparing the electrodes for use, but it should be done after attaching the electrodes to the patient's skin. This choice does not address the initial step in TENS treatment, which is setting the stimulation level. .
Correct Answer is C
Explanation
The correct answer is: C. Decreased energy.
Choice A reason: Hypotension is not typically associated with obstructive sleep apnea (OSA). OSA is more commonly linked with hypertension due to the frequent arousals during sleep that activate the sympathetic nervous system, leading to increased blood pressure.
Choice B reason: Pneumonia is an infection of the lungs and is not a direct consequence of OSA. While OSA can affect the respiratory system, it does not cause pneumonia. However, individuals with OSA may have a higher risk of respiratory infections due to compromised breathing during sleep.
Choice C reason: Decreased energy is a common symptom of OSA. People with OSA experience repeated episodes of partial or complete upper airway obstruction during sleep, leading to disrupted sleep patterns and insufficient rest. This results in daytime sleepiness and fatigue, which are hallmark signs of the condition.
Choice D reason: Thyroid disease, specifically hypothyroidism, can be associated with OSA, but it is not a direct finding of the condition. Hypothyroidism can lead to changes in the soft tissues of the upper airway and contribute to the development of OSA, but it is not a symptom used to diagnose OSA.
