Questions and Answers

1.

Which of these is NOT one of the areas of dysfunction caused by sleep deprivation?
- A.
  
  Emotional
- B.
  
  Respiratory
- C.
  
  Cognitive
- D.
  
  Endocrine
- E.
  
  Other physiological
Correct Answer
B. Respiratory

Explanation
Sleep deprivation can cause dysfunction in various areas, including emotional, cognitive, endocrine, and other physiological functions. However, respiratory dysfunction is not typically associated with sleep deprivation. While sleep deprivation may lead to respiratory symptoms such as snoring or sleep apnea, it is not considered one of the primary areas of dysfunction caused by lack of sleep.

Which of the following is true of meditative states?
- A.
  
  They are associated with an increase in delta brain waves
- B.
  
  They are similar to states of deep sleep
- C.
  
  They are associated with physical indicators of relaxation, such as slowed pulse
- D.
  
  All of the above
Correct Answer
C. They are associated with pHysical indicators of relaxation, such as slowed pulse

Explanation
Meditative states are associated with physical indicators of relaxation, such as a slowed pulse. This means that when someone is in a meditative state, their heart rate decreases, indicating a state of relaxation. This is one of the key characteristics of meditation, as it allows individuals to enter a state of deep relaxation and calmness.

A person who has recently ingested a recreational drug cannot sleep and appears aggressive, paranoid, and restless. What might this drug have been?
- A.
  
  Valium
- B.
  
  Morphine
- C.
  
  Heroin
- D.
  
  Crystal meth
Correct Answer
D. Crystal meth

Explanation
The person's symptoms of being unable to sleep, appearing aggressive, paranoid, and restless are consistent with the effects of crystal meth. Crystal meth is a powerful stimulant that can cause insomnia, increased energy, aggression, paranoia, and restlessness. Valium is a sedative that would have the opposite effect of causing drowsiness and relaxation. Morphine and heroin are opioids that would also have sedative effects rather than causing agitation and restlessness. Therefore, crystal meth is the most likely drug based on the described symptoms.

4.

What term describes the need, as time goes on, for more and more of a drug to get the same effect?
- A.
  
  Physical dependence
- B.
  
  Psychological dependence
- C.
  
  Tolerance
- D.
  
  Withdrawal
Correct Answer
C. Tolerance

Explanation
Tolerance refers to the phenomenon where the body becomes less responsive to a drug over time, requiring higher doses to achieve the same effect. This can occur due to various factors, such as the body adjusting to the presence of the drug or the drug becoming less effective. Tolerance is often associated with the development of physical dependence, where the body becomes reliant on the drug to function normally. Psychological dependence, on the other hand, refers to the emotional and psychological reliance on a drug. Withdrawal refers to the symptoms experienced when a drug is abruptly stopped or reduced.

Which of the following accurately describes people who have sleep apnea?
- A.
  
  They tend to be alert during the day
- B.
  
  They stop breathing periodically during the night
- C.
  
  They tend to sleep very heavily at night
- D.
  
  All of the above
Correct Answer
B. They stop breathing periodically during the night

Explanation
People who have sleep apnea experience periods during the night where they stop breathing. This is a characteristic symptom of sleep apnea. The other options, such as being alert during the day and sleeping heavily at night, may or may not apply to individuals with sleep apnea, as these can vary depending on the severity of the condition and other factors.

Which of the following can hypnosis not do?
- A.
  
  Produce anesthesia
- B.
  
  Reduce inhibitions
- C.
  
  Cause people to act against their will
- D.
  
  Cause changes in behavior after hypnosis has ended
Correct Answer
C. Cause people to act against their will

Explanation
Hypnosis cannot cause people to act against their will. Hypnosis is a state of heightened suggestibility, where individuals are more open to suggestions, but they still have control over their actions. They cannot be forced to do anything that goes against their moral or ethical beliefs or their fundamental desires. While hypnosis can influence behavior and reduce inhibitions, it cannot make someone act against their own volition.

What does the activation-synthesis theory propose?
- A.
  
  Dreams arise when the cortex of the brain tries to make meaning out of random neural impulses
- B.
  
  Dreams allow people to express unconscious wishes that are unacceptable in real life
- C.
  
  Dreams express people’s most pressing concerns
- D.
  
  Dreams arise during the brain’s routine housekeeping functions
Correct Answer
A. Dreams arise when the cortex of the brain tries to make meaning out of random neural impulses

Explanation
The activation-synthesis theory proposes that dreams arise when the cortex of the brain tries to make meaning out of random neural impulses. According to this theory, during REM sleep, the brainstem sends random signals to the cortex, which then tries to interpret these signals and create a narrative or story. This theory suggests that dreams are not necessarily meaningful or symbolic, but rather a result of the brain's attempt to make sense of random neural activity during sleep.

When does the REM rebound effect occur?
- A.
  
  When sleep spindles are occurring
- B.
  
  As people age
- C.
  
  After a period of REM deprivation
- D.
  
  Mostly in newborn babies
Correct Answer
C. After a period of REM deprivation

Explanation
The REM rebound effect occurs after a period of REM deprivation. This means that when a person is deprived of REM sleep, their body compensates by increasing the amount and intensity of REM sleep in subsequent sleep cycles. This rebound effect is believed to be a mechanism that helps restore and prioritize the necessary amount of REM sleep that may have been missed.

What does the suprachiasmatic nucleus do?
- A.
  
  Secretes melatonin, which regulates the sleep cycle
- B.
  
  Is used to measure eye activity during sleep
- C.
  
  Is the organ that causes dreaming
- D.
  
  Regulates circadian rhythms of sleep
Correct Answer
D. Regulates circadian rhythms of sleep

Explanation
The suprachiasmatic nucleus is responsible for regulating circadian rhythms of sleep. Circadian rhythms are the 24-hour cycles that our bodies go through, including sleep-wake cycles. The suprachiasmatic nucleus receives signals from the eyes about light and darkness, and it helps to synchronize our internal body clock with the external environment. It sends signals to various parts of the brain and body to promote wakefulness during the day and sleepiness at night. Therefore, it plays a crucial role in maintaining a regular sleep-wake cycle.

What type of brain waves predominate in stage 4 sleep?
- A.
  
  Delta waves
- B.
  
  Alpha waves
- C.
  
  Theta waves
- D.
  
  Beta waves
Correct Answer
A. Delta waves

Explanation
Delta waves are the correct answer because they are the slowest brain waves that occur during deep sleep, specifically in stage 4 sleep. These waves have a frequency of 0.5 to 4 Hz and are associated with restorative and regenerative processes in the body. Delta waves are characterized by high amplitude and are typically seen in individuals who are in a deep, dreamless sleep.
