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
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.
Correct Answer is C
Explanation
The role of the risk manager is to identify and analyze the factors that contributed to the adverse event and to implement strategies to prevent or reduce the likelihood of recurrence. The risk manager is not concerned with assigning blame or protecting the staff from litigation, but rather with improving the quality and safety of care.
Choice A is wrong because it implies a punitive approach that does not address the underlying system issues.
Choice B is wrong because it suggests a defensive attitude that does not foster a culture of learning and improvement.
Choice D is wrong because it assumes that the nurses were not aware of the patient’s fall risk, which may not be the case.
The risk manager should investigate all aspects of the situation, including the communication and documentation of the patient’s fall risk assessment and interventions.
