1.
Obstructive sleep apnea (or OSA) is usually caused when
Correct Answer
D. All of the above
Explanation
Anything that obstructs the airway, including excess weight that causes pressure on the neck or throat and the tongue slipping back into the throat, can cause apnea.
2.
An apneic event occurs when a person stops breathing during sleep for four seconds or more.
Correct Answer
B. False
Explanation
An apneic event occurs when breathing stops for 10 seconds or more.
3.
When a person stops breathing during sleep for 10 seconds, 5 to 15 times during an hour, he or she has
Correct Answer
A. Mild sleep apnea.
Explanation
When a person stops breathing for 10 seconds, 5 to 15 times during an hour, it indicates mild sleep apnea. Sleep apnea is a sleep disorder characterized by interruptions in breathing during sleep. Mild sleep apnea refers to a less severe form of the condition, where breathing pauses occur relatively infrequently. Moderate sleep apnea would involve more frequent breathing interruptions, while severe sleep apnea would entail even more frequent and prolonged pauses in breathing during sleep.
4.
When a person stops breathing during sleep for ten seconds, 15 to 30 times during an hour, he or she has
Correct Answer
B. Moderate sleep apnea.
Explanation
When a person stops breathing during sleep for ten seconds, 15 to 30 times during an hour, it indicates moderate sleep apnea. Sleep apnea is a sleep disorder characterized by pauses in breathing or shallow breaths during sleep. Mild sleep apnea would involve fewer episodes of breathing cessation, while severe sleep apnea would involve more frequent and longer pauses in breathing. Therefore, based on the given information, the correct answer is moderate sleep apnea.
5.
When a person stops breathing during sleep for ten seconds, 30 times or more during an hour, he or she has
Correct Answer
C. Severe sleep apnea.
Explanation
When a person stops breathing for ten seconds or more during sleep, 30 times or more during an hour, it indicates a severe case of sleep apnea. Sleep apnea is a sleep disorder characterized by repeated pauses in breathing during sleep. These pauses, known as apneas, can lead to a decrease in oxygen levels in the blood and disrupt normal sleep patterns. Severe sleep apnea is diagnosed when there are frequent and prolonged episodes of apnea, indicating a significant impairment in breathing during sleep.
6.
Of the following, which are the three main options for treatment of OSA? (Check all that apply.)
Correct Answer(s)
A. Surgery
C. PAP therapy
D. Oral appliance therapy
Explanation
The three main options for the treatment of OSA are surgery, PAP therapy, and oral appliance therapy. Surgery may be recommended in cases where there is a physical obstruction causing the sleep apnea. PAP therapy, which stands for positive airway pressure therapy, involves using a machine to deliver a continuous flow of air to keep the airway open during sleep. Oral appliance therapy involves using a custom-fitted device, similar to a mouthguard, to reposition the jaw and tongue to keep the airway open. Over-the-counter medications are not typically used as a main treatment option for OSA.
7.
What are some of the common complaints associated with PAP therapy? (Check all that apply.)
Correct Answer(s)
B. Noisy and cumbersome
D. Difficult to travel with
Explanation
PAP therapy is highly effective as a method of treatment; however, many patients cannot tolerate the treatment because the machines are noisy or the masks are uncomfortable. Insurance will cover the expense associated with PAP therapy.
8.
Oral appliances are used to advance the jaw forward, allowing more room for the tongue and keeping the airway open.
Correct Answer
A. True
Explanation
Oral appliances are indeed used to advance the jaw forward, which helps create additional space for the tongue and keeps the airway open. This can be particularly beneficial for individuals with sleep apnea or other breathing difficulties during sleep. By positioning the jaw in a more forward position, these appliances can help prevent the tongue from obstructing the airway, allowing for better airflow and reducing the likelihood of breathing interruptions during sleep.
9.
Usually, only adult, male patients need to fill out a questionnaire.
Correct Answer
B. False
Explanation
All patients should fill out a questionnaire.
10.
Which of the following have been linked to sleep apnea? (Check all that apply.)
Correct Answer(s)
A. Stroke
B. Heart attack
C. High blood pressure
D. Diabetes
E. Obesity
F. Cancer
Explanation
These are only some of the symptoms, signs and diseases associated with sleep apnea.
11.
People with untreated sleep apnea have a reduced lifespan.
Correct Answer
A. True
Explanation
People with untreated sleep apnea have a reduced lifespan because the condition causes repeated pauses in breathing during sleep, leading to a decrease in oxygen levels in the body. This can result in various health complications such as high blood pressure, heart disease, stroke, and diabetes. Over time, these conditions can significantly impact a person's overall health and increase the risk of premature death. Therefore, it is important to diagnose and treat sleep apnea to improve both the quality and length of life.
12.
People with untreated sleep apnea spend ______ times as much on medical care during their lifetimes in comparison to those who do not have sleep apnea.
Correct Answer
C. 3
Explanation
People with untreated sleep apnea spend three times as much on medical care during their lifetimes compared to those who do not have sleep apnea. This suggests that sleep apnea can lead to various health complications and the need for extensive medical treatment, resulting in higher healthcare costs.
13.
Cardiovascular damage caused by sleep apnea puts people at greater risk for
Correct Answer
C. Both heart attack and stroke.
Explanation
Sleep apnea is a condition where a person's breathing is repeatedly interrupted during sleep. This interruption in breathing can lead to a decrease in oxygen levels in the blood, causing stress on the cardiovascular system. Over time, this can result in damage to the blood vessels and increase the risk of cardiovascular events such as heart attacks and strokes. Therefore, individuals with sleep apnea are at a greater risk for both heart attack and stroke.
14.
Snoring is a common symptom of sleep apnea.
Correct Answer
A. True
Explanation
People who snore may not have sleep apnea; however, it is a common symptom and those who do snore are more likely to be diagnosed with sleep apnea at some time.
15.
Why are excessive sleepiness, lack of energy and fatigue symptoms of sleep apnea? (Check all that apply.)
Correct Answer(s)
A. OSA patients spend a significant amount of time at night in fight or flight mode, with resultant elevated blood pressure, heart rate, and respiration.
B. OSA causes disrupted sleep patterns which leads to insufficient amounts of sleep.
C. OSA patients spend the night fighting to breathe.
Explanation
All of these are just some of the reasons that OSA patients will feel sleepiness and fatigue throughout the day.
16.
Getting equal to or less than four hours of sleep during one night has a sedative effect equivalent to legal intoxication.
Correct Answer
A. True
Explanation
This is equivalent to a BAC of .095%.
17.
Which of the following is true concerning driving while excessively drowsy?
Correct Answer
D. All of the above.
Explanation
All of the statements provided are true concerning driving while excessively drowsy. The costs associated with sleep-related accidents are indeed as high as 10 to 40 billion dollars. At least 30% of all motor vehicle accidents are caused by sleep deprivation. Additionally, driving while drowsy impairs driving as much as or even more than alcohol. Therefore, the correct answer is "All of the above."
18.
All of the top ten prescription medications in the United States are related to the signs and symptoms or comorbidities of OSA.
Correct Answer
B. False
Explanation
Seven of the top ten prescription medications are related to the signs and symptoms or comorbidities of OSA.
19.
The Epworth Sleepiness Scale is the gold standard for testing sleepiness and is a required part of records for all cases.
Correct Answer
A. True
Explanation
The Epworth Sleepiness Scale is widely recognized as the gold standard for measuring sleepiness. It is a standardized questionnaire that assesses an individual's likelihood of falling asleep in various situations. This scale is commonly used in clinical settings to evaluate sleep disorders and is considered an essential component of medical records for such cases. Therefore, the statement is true.
20.
Morning headaches have been linked to oxygen desaturation events.
Correct Answer
A. True
Explanation
Oxygen desaturation events occur when a patient has an apneic event. Thus, these types of headaches, along with cluster headaches, are linked to sleep apnea.
