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.

Explanation
The correct answer is choice A. Cataracts are a cloudy, opaque area over the lens of one eye that can impair vision
Choice B is wrong because diabetic retinopathy is a condition that affects the blood vessels of the retina, not the lens. It can cause blurred vision, floaters, or vision loss
Choice C is wrong because glaucoma is a condition that damages the optic nerve due to high pressure in the eye. It can cause blind spots, halos around lights, or vision loss
Choice D is wrong because macular degeneration is a condition that damages the macula, the central part of the retina. It can cause blurred or no vision in the center of the visual field

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.
