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 C
Explanation
This type of anemia is caused by the reduced absorption of vitamin B12 in the small intestine after gastric bypass surgery. Vitamin B12 is needed for the production of healthy red blood cells and nerve function. The symptoms of vitamin B12 deficiency anemia include sore tongue, tingling in the fingers, and balance problems.
Choice A is wrong because folic acid deficiency anemia is caused by the lack of folic acid in the diet or increased demand for folic acid, such as during pregnancy.
Folic acid is also needed for red blood cell production, but it does not cause nerve symptoms.
Choice B is wrong because aplastic anemia is caused by the failure of the bone marrow to produce enough blood cells.
It is not related to gastric bypass surgery or nutrient deficiency. It can be caused by infections, drugs, radiation, or autoimmune diseases.
Choice D is wrong because acquired anemia is a general term for any type of anemia that is not inherited or present at birth.
It can have many causes, such as blood loss, infection, inflammation, or chronic disease.
It does not specify the type of anemia or the underlying mechanism. Normal ranges for hemoglobin are 13.5 to 17.5 g/dL for men and 12 to 15.5 g/dL for women. Normal ranges for vitamin B12 are 200 to 900 pg/mL.
Correct Answer is ["A","C","D"]
Explanation
Choice A is correct because maintaining a regular sleep routine can help regulate your circadian rhythm, which is your body’s natural sleep-wake cycle. This can improve the quality and quantity of your sleep and reduce daytime sleepiness.
Choice B is wrong because eating three large meals a day can cause fluctuations in your blood sugar levels, which can affect your energy levels. It is better to eat smaller, more frequent meals and snacks that contain a balance of protein and carbohydrates to keep your blood sugar stable and provide sustained energy. Choice C is correct because limiting refined sugar, fried foods and processed foods can help prevent fatigue by reducing inflammation and oxidative stress in your body.
These foods can also cause spikes and crashes in your blood sugar levels, which can make you feel tired and hungry. Instead, you should eat more anti-inflammatory foods, such as fruits, vegetables, nuts, seeds and fish.
Choice D is correct because taking daily walks can help prevent fatigue by increasing your blood circulation, oxygen delivery and endorphin production. Exercise can also improve your mood, sleep quality and immune system.
Choice E is wrong because increasing caffeine intake can have the opposite effect of preventing fatigue.
Caffeine is a stimulant that can temporarily boost your energy levels, but it can also disrupt your sleep, cause dehydration, increase anxiety and lead to withdrawal symptoms
