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
Increasing regular weight-bearing activities can help prevent osteoporosis by stimulating bone formation and improving muscle strength. Weight-bearing activities are those that make your bones and muscles work against gravity, such as walking, jogging, dancing, or lifting weights.
Choice A is wrong because protecting the client’s bones with strict bedrest can actually increase the risk of osteoporosis by reducing bone density and muscle mass. Bedrest should be avoided unless medically necessary.
Choice B is wrong because providing the client with assisted range of motion exercises twice daily is not enough to prevent osteoporosis. While these exercises can help maintain joint mobility and flexibility, they are not weight bearing and do not stimulate bone formation.
Choice C is wrong because decreasing the amount of calcium in the client’s diet can also increase the risk of osteoporosis. Calcium is an essential mineral for bone health and adults need 700mg a day, which can be obtained from foods such as dairy products, leafy green vegetables, tofu, and dried fruit. Vitamin D is also important for bone health as it helps the body absorb calcium.
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.
