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
Explanation
Fluid volume excess is wrong because appendicitis does not cause fluid retention or overload. It may cause fluid loss due to vomiting, fever, or rupture of the appendix. Therefore, a more appropriate nursing diagnosis would be the risk for deficient fluid volume.
Choice B. Risk for infection is correct because appendicitis is an inflammatory condition that can lead to bacterial infection, especially if the appendix ruptures and causes peritonitis or abscess formation.
Choice C. Ineffective thermoregulation is correct because appendicitis can cause fever due to inflammation and infection.
Choice D. Pain is correct because appendicitis causes acute abdominal pain that usually starts in the periumbilical area and then localizes to the right lower quadrant. The pain may be accompanied by nausea, vomiting, and rebound tenderness.
