Choose the one alternative that best completes the statement or answers the questions 1) Which of the following should the nurse identify as symptoms of hypovolemic shock? (Select all that apply.) A) A temperature of 97.6°F (36.4°C) B) A decrease in blood pressure of 20 mm Hg when the patient sits up C) Capillary refill time greater than 3 seconds D) Restlessness E) Sinus bradycardia of 55 beats per minute Answer: B, C, D Explanation: A) (Note: This requires multiple responses to be correct.) Due to decreased blood flow to the brain and peripheral areas when blood is shunted to maintain the vital organs, cerebral hypoxia occurs. The action of standing will decrease the blood to the brain by gravitational pull and will require increased peripheral resistance or cardiac output to maintain cerebral blood supply. #1 is incorrect. Fever wil increase oxygen demands but is unrelated to hypovolemic shock unless prolonged fever has caused severe dehydration, reducing the circulating blood volume. Hypovolemic shock reduces temperatures by peripheral shunting of blood away from the extremities and reducing the core metabolic rate. If septic shock is present fever might be present, but it is not present in all patients with hypovolemic shock. #5 is incorrect. Bradycardia not present. The compensatory response is to increase the heart rate (tachycardia) to circulate the blood faster to make up for the fluids that are not present in hypovolemic shock. Nursing Process: Assessment Cognitive Level: Application Category of Need: Physiological Integrity–Physiological Adaptations B) (Note: This requires multiple responses to be correct.) Due to decreased blood flow to the brain and peripheral areas when blood is shunted to maintain the vital organs, cerebral hypoxia occurs.

Nursing Process: Assessment Cognitive Level: Application Category of Need: Physiological Integrity–Physiological Adaptations 2) Which of the following lab findings should cause the nurse to suspect that a patient was developing hypovolemic shock? A) Serum sodium of 130 mEq/L (130 mmol/L) B) Metabolic alkalosis validated by arterial blood gases C) Serum lactate of 5 mmol/L D) SvO2 greater than 80% Answer: B Explanation: A) Metabolic acidosis is present due to an accumulation of carbonic acid, leaving a bicarbonate deficit from decreased tissue perfusion. #1 is incorrect. The sodium level in hypovolemic shock is elevated above the normal values of 135 to 145 mEq/L, not depressed. The increased concentration of sodium occurs when the circulating volume is decreased, concentrating the elements. #3 is incorrect. Serum lactate is greater than 4 mmol/L as a result of tissue ischemia, hypoxia, and breakdown from decreased blood flow with hypovolemic shock. Normal lactate levels are 0.3 to 2.6 mmol/L. #4 is incorrec SvO2 (mixed venous oxygen saturation) would be less than 60% due to decreased circulating blood volume or decrease in cells to carry the oxygen. There2foirse, O carried less efficiently and decreased, not increased. The normal values f2orarSevO between 60% and 80%.
