Chapter 17 : Caring for Clients in Shock Questions
Question 1 of 5
The nurse is performing hourly assessments on a client in the compensation stage of shock. In documenting the hourly urine output of $40 \mathrm{~mL}$ from the Foley catheter, which nursing action is most appropriate?
Correct Answer: C
Rationale: Urine output above $35 \mathrm{~mL} /$ hour or $500 \mathrm{~mL} /$ day indicates adequate kidney perfusion. The hourly output would be documented in the client record. There is no need to reposition the client or look for a kink because adequate amounts of urine is collecting in the tube. There is no need to notify the physician or family.
Question 2 of 5
The nurse is planning care for a client diagnosed with cardiogenic shock. Which nursing intervention is most helpful to decrease myocardial oxygen consumption?
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.
Question 3 of 5
The community health nurse finds the client collapsed outdoors. The nurse assesses that the client is shallow breathing and has a weak pulse. Emergency medical services (EMS) is notified by the neighbor. Which nursing action is helpful while waiting for the ambulance?
Correct Answer: B
Rationale: The client has shallow respiration and a weak pulse implying limited circulation and gas exchange. Most helpful would be to elevate the legs higher than the heart to promote blood perfusion to the heart, lungs, and brain. A cool compress would not be helpful nor would shaking the client to arouse. A client can be covered with a blanket, but this is not the most helpful.
Question 4 of 5
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?
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.
Question 5 of 5
A nurse educator is teaching students the types of shock and associated causes. Which combination(s) of shock type and causative factors is correct? Select all that apply.
Correct Answer: A,C,D,E
Rationale: Shock is a life-threatening condition that occurs when arterial blood flow and oxygen delivery to tissues and cells are inadequate. Hypovolemic shock occurs when the volume of extracellular fluid is significantly diminished due to the loss of or reduced blood or plasma. Obstructive shock occurs when there is interference in blood flow through the heart. Cardiogenic shock occurs when the heart is ineffective in pumping possibly due to a myocardial infarction. Anaphylactic shock occurs from an allergen such as nuts. Septic shock occurs from a bacterial infection. Neurogenic shock results from an insult to the vasomotor center in the medulla or peripheral nerves.
