Name six behavioral symptoms of sleep deprivation. | Irritability, withdrawn state, apathy, decreased motivation, agitation and hyperactivity. |
Name three things that might cause REM deprivation. | Sleep only 1st half of usual TST, awakened every hour/frequently and taking medication(s) that suppresses REM sleep. |
What may occur when a person is REM deprived and provide an example. | REM rebound, which is when you start seeing dreamscape images in reality. |
What are the five ways in which insomnia is defined? | Difficulty falling asleep (longer than 30 mins), difficulty staying asleep/frequent awakening, difficulty going back to sleep after awakening, awakening too early, or any combination thereof. |
What is the incidence rate of insomnia? | It is the most prevalent sleep disorder. |

What are the three types of sleep apnea? | Obstructive, central and mixed. |
What is obstructive sleep apnea? | Upper airway is blocked, requiring respiratory effort. |
What is central sleep apnea? | No respiratory effort, where impulse to breath temporarily fails (e.g. COPD with lots of 02). |

What does physical/mechanical therapy for sleep apnea entail? | Dental appliance, positive airway pressure devices to keep the airway flowing and open (e.g. CPAP and BiPaP). |
What does surgery for sleep apnea entail? | Nasal septum repair and palatal surgery (e.g. uvulopalatopharyngoplasty or UP3). |
What are five measures to promote sleep? | Adequate assessment, planning activities to maximize time for rest & sleep, provide comfort measures, establish sleep environment and patient education. |
Name four things you ask a patient to make a proper sleep assessment. | Time individual goes to sleep/awakens, number of hours of sleep, if naps are taken(when and how long), and if the patient feels rested. |
What are eight useful additional data if a sleep problem is indicated? | Symptoms, medications, physical health, emotional status, major life changes, sleep environment, consumption of alcohol/caffeine and what was already tried to alleviate the problem. |
What are six things that are good for establishing a healthy sleep environment? | Presleep/bedtime routine, decreased light & noise, avoid excessive physical & mental stimulation, consistent time for sleep, voiding before goign to bed, and avoiding alcohol/smoking. |
