Which assessment finding indicates to the nurse that a client is exhibiting early clinical manifestations of the compensatory stage of shock? (Select all that apply).
Restlessness
Cool moist skin
Increased bowel sounds
Increased respiratory rate
Decreased blood glucose
Correct Answer : A,B,D
Choice A reason: Restlessness is one of the early clinical manifestations of the compensatory stage of shock. The body responds to decreased tissue perfusion and oxygenation by stimulating the sympathetic nervous system, which results in anxiety and restlessness. This response indicates that the body's compensatory mechanisms are being activated in an attempt to maintain adequate blood flow and oxygenation to vital organs. The increased release of catecholamines leads to these symptoms as the body tries to compensate for the shock state.
Choice B reason: Cool moist skin is another early sign of the compensatory stage of shock. During this stage, peripheral vasoconstriction occurs as the body attempts to redirect blood flow to vital organs like the heart and brain. This vasoconstriction leads to reduced blood flow to the skin, causing it to become cool and clammy. The skin's moisture is due to the activation of sweat glands, another effect of the sympathetic nervous system's response to shock. This mechanism is essential for preserving core body temperature and ensuring that critical organs receive adequate perfusion during the shock state.
Choice C reason: Increased bowel sounds are not typically associated with the compensatory stage of shock. Instead, the body’s response to shock generally includes decreased gastrointestinal activity due to the redirection of blood flow away from the gastrointestinal tract. This prioritization of blood flow to vital organs like the heart, lungs, and brain leads to a reduction in digestive functions. Therefore, increased bowel sounds are unlikely to be an early manifestation of the compensatory stage of shock, making this choice incorrect in the context of shock assessment.
Choice D reason: Increased respiratory rate is a key indicator of the compensatory stage of shock. As the body attempts to compensate for reduced oxygen delivery to tissues, the respiratory rate increases to enhance oxygen uptake and carbon dioxide elimination. This tachypnea helps to maximize oxygenation and support metabolic needs during the early stages of shock. The body's drive to maintain homeostasis triggers this response, ensuring that despite the decreased perfusion, oxygen levels in the blood are maintained as much as possible.
Choice E reason: Decreased blood glucose is not typically an early sign of the compensatory stage of shock. In fact, the body's stress response to shock usually involves the release of stress hormones like cortisol and catecholamines, which can increase blood glucose levels by stimulating gluconeogenesis and glycogenolysis. This increase in blood glucose provides additional energy to vital organs during the stressful period. Hence, decreased blood glucose is not considered a primary early manifestation of the compensatory stage of shock.

Correct Answer is B
Explanation
Choice A reason: Respiratory acidosis. Respiratory acidosis occurs when there is inadequate ventilation, leading to increased carbon dioxide levels in the blood. Hyperventilation would not cause respiratory acidosis.
Choice B reason: Respiratory alkalosis. Hyperventilation results in excessive expulsion of carbon dioxide, leading to a decrease in carbonic acid levels in the blood. This causes respiratory alkalosis, which is expected in the early stages of hypovolemic shock as the body attempts to compensate for decreased oxygen delivery.
Choice C reason: Metabolic acidosis. Metabolic acidosis results from an accumulation of acid or loss of bicarbonate in the body. It is typically seen in the later stages of shock when lactic acid builds up due to anaerobic metabolism.
Choice D reason: Metabolic alkalosis. Metabolic alkalosis occurs due to an excessive loss of acids (e.g., through vomiting) or an accumulation of bicarbonate. Hyperventilation does not cause metabolic alkalosis.
Correct Answer is B
Explanation
Choice A reason: Decreased systemic vascular resistance, decreased CVP. In hypovolemic shock, the body compensates by increasing systemic vascular resistance to maintain blood pressure. Therefore, decreased systemic vascular resistance is not consistent with hypovolemic shock. Central venous pressure (CVP) would be low due to reduced blood volume.
Choice B reason: Increased systemic vascular resistance, decreased CVP. Hypovolemic shock is characterized by low blood volume, leading to decreased cardiac output and low CVP. The body compensates by increasing systemic vascular resistance to maintain blood pressure, making this the correct answer.
Choice C reason: Increased systemic vascular resistance, increased CVP. While systemic vascular resistance increases, CVP is typically decreased in hypovolemic shock due to the lack of circulating blood volume.
Choice D reason: Decreased systemic vascular resistance, increased CVP. Decreased systemic vascular resistance and increased CVP are not consistent with hypovolemic shock. These parameters might be seen in conditions with different hemodynamic profiles.
