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 A
Explanation
This is because people with COPD are more likely to catch respiratory infections such as colds, flu and pneumonia, which can worsen their symptoms and cause further lung damage. An influenza vaccine can help prevent flu and reduce the risk of complications.
Choice B. A broad-spectrum antibiotic is wrong because antibiotics are only effective against bacterial infections, not viral ones. Antibiotics are usually prescribed for COPD exacerbations caused by bacterial infections, but not for prevention.
Choice C. A bronchodilator is wrong because bronchodilators are medications that relax the muscles around the airways and make breathing easier. They are used to treat the symptoms of COPD, but they do not prevent respiratory infections.
Choice D. A corticosteroid is wrong because corticosteroids are anti inflammatory drugs that reduce swelling and mucus production in the airways. They are also used to treat the symptoms of COPD, but they do not prevent respiratory infections. In fact, long-term use of corticosteroids may increase the risk of infections by suppressing the immune system.
Correct Answer is C
Explanation
Splenomegaly and jaundice are signs of hemolytic anemia, a disorder in which red blood cells are destroyed faster than they are made.
Splenomegaly is an enlargement of the spleen, which may trap and destroy healthy red blood cells. Jaundice is a yellowing of the skin and eyes caused by the buildup of bilirubin, a waste product of hemoglobin breakdown. Choice A is wrong because red, sore tongue is a sign of vitamin B12 deficiency anemia, not hemolytic anemia.
Choice B is wrong because pica is a craving for nonfood items, such as ice, dirt, or starch. It is a sign of iron deficiency anemia, not hemolytic anemia. Choice D is wrong because paresthesias are sensations of tingling, numbness, or prickling in the hands or feet. They are a sign of pernicious anemia, a type of vitamin B12 deficiency anemia, not hemolytic anemia.
Normal ranges for red blood cell count are 4.5 to 5.9 million cells per microliter for men and 4.1 to 5.1 million cells per microliter for women. Normal ranges for hemoglobin are 13.5 to 17.5 grams per deciliter for men and 12.0 to 15.5 gramsper deciliter for women. Normal ranges for bilirubin are 0.1 to 1.2 milligrams per deciliter for adults.
