In a state of shock, the body attempts to maintain homeostasis by maintaining priority blood flow to the:

Myocardium and brain

Pulmonary vasculature

Small and large bowel

Hepatic and renal vasculature

Answer and Explanation

The Correct Answer is A

Choice A reason:

In a state of shock, the body prioritizes blood flow to vital organs such as the myocardium (heart muscle) and the brain. This is because these organs are essential for survival, and their function is critical. The body's compensatory mechanisms ensure that blood is diverted to these areas to maintain their perfusion, even at the expense of less vital organs.

Choice B reason:

The pulmonary vasculature, which involves the blood vessels of the lungs, is important for gas exchange but is not specifically prioritized in the same way that the myocardium and brain are during shock. While maintaining adequate oxygenation is crucial, the body’s immediate focus is on sustaining the heart and brain.

Choice C reason:

The small and large bowel are not considered high-priority organs during shock. Blood flow to the gastrointestinal tract can be reduced to preserve perfusion to more vital organs. This reduced blood flow can result in decreased bowel activity and hypoactive bowel sounds.

Choice D reason:

While the hepatic (liver) and renal (kidneys) vasculature are important for detoxification and fluid balance, they are not prioritized over the heart and brain during shock. Reduced perfusion to these organs can lead to liver and kidney dysfunction, but the immediate priority is ensuring the survival of the heart and brain.

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.

A. Cool, moist skin. B. Increased bowel sounds. C. Restlessness. D. Increased respiratory rate. E. Decreased blood glucose.

Correct Answer is ["A","C","D"]

Explanation

Choice A reason: Cool, moist skin. Cool, moist skin is an early sign of shock as the body redirects blood flow away from the skin to vital organs. This is part of the body's compensatory mechanisms to maintain perfusion.

Choice B reason: Increased bowel sounds. Bowel sounds typically decrease during shock due to reduced blood flow to the gastrointestinal tract. Increased bowel sounds would not be expected.

Choice C reason: Restlessness. Restlessness is an early sign of shock indicating reduced oxygen delivery to the brain. The body responds by becoming more alert and anxious, reflecting increased sympathetic nervous system activity.

Choice D reason: Increased respiratory rate. An increased respiratory rate is a compensatory mechanism to improve oxygenation and reduce carbon dioxide levels in the blood. This is common in the early stages of shock.

Choice E reason: Decreased blood glucose. Blood glucose levels are generally not an immediate indicator in the early stages of shock. The body's stress response can actually increase blood glucose levels initially.

The nurse understands that which hemodynamic parameters are consistent with hypovolemic shock? Decreased cardiac output and:

Correct Answer is B

Explanation

Which assessment findings indicate to the nurse that a client is exhibiting early clinical manifestations of the compensatory stage of shock? (Select all that apply.)

Correct Answer is ["A","C","D"]

Explanation

The nurse is caring for a patient who is experiencing shock. What finding would the nurse expect when assessing the abdomen?

What clinical manifestation distinguishes or separates neurogenic shock from other forms of shock?

The pathophysiology of shock is best described as:

The nurse caring for a client in the early stages of hypovolemic shock who is hyperventilating. The nurse monitors for which acid-base imbalance based on this clinical presentation?

During the initial stage of shock, which manifestation should the nurse monitor for when assessing the client?

The nurse is caring for a patient who is the victim of a traumatic motor vehicle accident. Vital signs are: T-98.8 oral, P-140, B/P-86/52, R-28, pulse oximetry-92% on room air. The nurse would suspect which type of shock?

What is a late sign of septic shock?

What is an integumentary manifestation of anaphylactic shock?
