A nurse is assisting with teaching a class about physical manifestations associated with the fight-or-flight response to stress.
Which of the following manifestations should the nurse include?
Decreased blood pressure.
Bronchial airway constriction.
Hypoglycemia.
Dilated pupils.
The Correct Answer is D
This is because the fight-or-flight response activates the sympathetic nervous system, which causes the pupils to dilate to allow more light and improve vision.
Choice A is wrong because the fight-or-flight response increases blood pressure by constricting blood vessels and increasing heart rate.
Choice B is wrong because the fight-or-flight response causes bronchial airway dilation to allow more oxygen intake and facilitate breathing.
Choice C is wrong because the fight-or-flight response causes hyperglycemia by stimulating the release of glucose from the liver and muscles to provide energy.
Normal ranges for blood pressure are 90/60 mmHg to 120/80 mmHg, for blood glucose are 70 mg/dL to 100 mg/dL, and for pupil size are 2 mm to 6 mm.

Correct Answer is A
Explanation
Watching television until falling asleep at night is a poor sleep habit because it can interfere with the body’s natural sleep-wake cycle and make it harder to fall asleep and stay asleep. Television can also expose the eyes to bright light and stimulating or stressful content, which can affect the production of melatonin, a hormone that regulates sleep.
Choice B is wrong because having a small snack and taking a bath before going to bed each day are good sleep habits that can promote relaxation and sleep quality.
Choice C is wrong because not taking naps throughout the day is a good sleep habit that can help maintain a consistent sleep schedule and avoid disrupting the night-time sleep.
Choice D is wrong because going to bed and getting up at the same times each day is a good sleep habit that can reinforce the body’s circadian rhythm and make it easier to fall asleep and wake up.
Correct Answer is ["A","C","D","E"]
Explanation
These are some of the criteria used to assist in making the diagnosis of chronic fatigue syndrome (CFS) according to the Institute of Medicine (IOM) 2015 report.
Choice B is wrong because recent exposure to influenza is not a criterion for CFS diagnosis. Although some cases of CFS may be triggered by viral infections, such as Epstein-Barr virus or human herpes virus 6, there is no specific evidence that influenza causes CFS.
Choice A is correct because CFS is not caused by a primary condition. CFS is a diagnosis of exclusion, meaning that other possible causes of fatigue, such as sleep disorders, anemia, diabetes, thyroid problems, or mental health issues, must be ruled out before making the diagnosis.
Choice C is correct because unrefreshing sleep is one of the required symptoms for CFS diagnosis. Patients with CFS may not feel better or less tired even after a full night of sleep despite the absence of specific objective sleep alterations. Choice D is correct because fatigue that is not relieved by stress reduction is another required symptom for CFS diagnosis. Patients with CFS experience post-exertional malaise (PEM), which means that their symptoms worsen after physical, mental, or emotional exertion that would not have caused a problem before the illness.
Choice E is correct because severe tiredness for 2 months or more is one of the additional manifestations that must be present for CFS diagnosis. The IOM 2015 report states that the fatigue associated with CFS must last for more than 6 months and occur at least half the time at moderate, substantial or severe intensity.
