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 ["B","C","D"]
Explanation
These are signs of anemia, which is a condition in which the blood lacks enough healthy red blood cells to carry adequate oxygen to the body’s tissues.
Anemia can cause fatigue, weakness, pale skin, cold hands and feet, dizziness, reduced immunity and shortness of breath.
Choice A is wrong because bradypnea is abnormally slow breathing, which is not a sign of anemia. Anemia can cause tachypnea, which is abnormally fast breathing.
Choice E is wrong because flushed skin is not a sign of anemia. Anemia can cause pallor, which is pale or yellowish skin.
Flushed skin can be a sign of other conditions, such as fever, infection or allergic reaction.
Normal ranges for hemoglobin levels vary depending on age and gender. For adult males, the normal range is 13.5 to 17.5 grams per deciliter (g/dL) of blood. For adult females, the normal range is 12 to 15.5 g/dL of blood.
Correct Answer is D
Explanation
A client with chronic bronchitis is expected to have a cough that produces sputum for at least 3 months during two successive years. This is due to the hyperplasia of mucous glands and bronchial wall inflammation that occur in chronic bronchitis.
Choice A is wrong because SpO2 >92% is not a specific finding for chronic bronchitis.
SpO2 is a measure of oxygen saturation in the blood and can vary depending on many factors, such as altitude, smoking, and lung diseases. SpO2 may be lower than normal in COPD patients due to airflow obstruction and impaired gas exchange.
Choice B is wrong because underweight is not a typical finding for chronic bronchitis.
Underweight may be more associated with emphysema, which is another component of COPD that involves the destruction of alveolar walls and enlargement of air spaces. Emphysema can cause weight loss due to increased work of breathing and decreased appetite.
Choice C is wrong because bradypnea is not a common finding for chronic bronchitis.
Bradypnea is abnormally slow breathing rate and can be caused by various conditions, such as brain injury, drug overdose, or sleep apnea. Chronic bronchitis usually causes tachypnea, which is abnormally fast breathing rate, due to hypoxia and hypercapnia.
