Which thermoregulatory condition is an elderly person most at risk for?
Hypothermia.
Normothermia.
Hyperthermia.
Malignant hyperthermia.
The Correct Answer is A
Hypothermia is a condition where the body temperature drops below 35°C (95°F) and affects the normal functioning of the body. Elderly people are more at risk for hypothermia because they have a lower muscle mass, a decreased
shiver reflex, and lower immunity. They also tend to have a lower body temperature and may not develop fevers when they contract a viral or bacterial illness.
Choice B. Normothermia is wrong because it means having a normal body temperature, which is around 37°C (98.6°F).
Choice C. Hyperthermia is wrong because it means having a high body temperature, which is above 37.5°C (99.5°F).
Hyperthermia can be caused by heat exposure, infection, inflammation, or certain medications.
Choice D. Malignant hyperthermia is wrong because it is a rare genetic disorder that causes a severe reaction to certain anesthetics or muscle relaxants.
It is not related to thermoregulation in elderly people.

Correct Answer is D
Explanation
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","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.
