The nurse is caring for a client diagnosed with shock. During report, the nurse reports the results of which assessment(s) that signal early signs of the decompensation stage? Select all that apply.
- A. Vital signs
- B. Nutrition
- C. Skin color
- D. Gait
- E. Urine output
- F. Peripheral pulses
Correct Answer: A,C,E,F
Rationale: Although shock can develop and progress quickly, the nurse monitors evidence of early signs that blood volume and circulation is becoming compromised. Vital signs, skin color, urine output related to blood perfusion of the kidneys, and peripheral pulses all provide assessment data relating blood volume and circulation.

The nurse is planning care for a client diagnosed with cardiogenic shock. Which nursing intervention is most helpful to decrease myocardial oxygen consumption?
- A. Limit interaction with visitors.
- B. Avoid heavy meals.
- C. Maintain activity restriction to bedrest.
- D. Arrange personal care supplies nearby.
Correct Answer: C
Rationale: Restricting activity to bedrest provides the best example of decreasing myocardial oxygen consumption. Inactivity reduces the heart rate and allows the heart to fill with more blood between contractions. The other options may be helpful, but the best option is limiting activity.
The nurse is caring for a client in the compensation stage of shock. The nurse knows that one of the body's mechanisms of compensation in this stage of shock is the renin- angiotensin-aldosterone system. What does this system do?
- A. Decreases peripheral blood flow
- B. Increases catecholamine secretion
- C. Increases the production of antidiuretic hormone
- D. Restores blood pressure
Correct Answer: D
Rationale: The renin-angiotensin-aldosterone system is a mechanism that restores blood pressure (BP) when circulating volume is diminished. It does not decrease peripheral blood flow, increase catecholamine secretion, or increase the production of antidiuretic hormone.
The nurse is caring for a client in septic shock. The nurse knows to closely monitor the client. What finding would the nurse observe when the client's condition is in its initial stages?
- A. A rapid, bounding pulse
- B. A slow but steady pulse
- C. A weak and thready pulse
- D. A slow and imperceptible pulse
Correct Answer: A
Rationale: A rapid, bounding pulse is observed in a client in the initial stages of septic shock. In case of hypovolemic shock, the pulse volume becomes weak and thready and circulating volume diminishes in the initial stage. In the later stages when the circulating volume has severely diminished, the pulse becomes slow and imperceptible, and pulse rhythm changes from regular to irregular.
The nurse is caring for a client in the irreversible stage of shock. The nurse is explaining to the client's family the poor prognosis. Which would the nurse be most accurate to explain as the rationale for imminent death?
- A. Endotoxins in the system
- B. Limited gas exchange
- C. Brain death
- D. Multiple organ failure
Correct Answer: D
Rationale: In the irreversible stage of shock, significant cells and organs are damaged. The client's condition reaches a 'point of no return' despite treatment efforts. Death occurs from multiple system failure as the kidneys, heart, lungs, liver, and brain cease to function.
The seasoned nurse is instructing the new graduate on information obtained from central venous pressure and pulmonary artery pressure. Which statement, made by the seasoned nurse, reflects the most pertinent information regarding circulation?
- A. Central venous pressure reflects the pressure in the right atrium or venae cavae.'
- B. A pulmonary artery pressure provides information about pressure on the left side of the heart.'
- C. The trend in central venous pressure is more helpful than isolated readings.'
- D. Pulmonary artery pressure and pulmonary capillary pressure is assessed by an inserted catheter.'
Correct Answer: B
Rationale: The most pertinent information to share with a new nurse is the information that the pulmonary artery pressure provides essential information about the effectiveness of left ventricle. The left ventricle is most pertinent to circulation. The other information is correct but not as pertinent.
