Chapter 17 : Caring for Clients in Shock Questions
Question 1 of 5
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?
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.
Question 2 of 5
The nurse is caring for a client with shock. The nurse is concerned about hypoxemia and metabolic acidosis with the client. What finding should the nurse analyze for evidence of hypoxemia and metabolic acidosis in a client with shock?
Correct Answer: B
Rationale: Analysis of ABG findings is essential for evidence of hypoxemia and metabolic acidosis. Low RBCs and hemoglobin correlate with hypovolemic shock and can lead to poor oxygenation. An elevated white blood cell count supports septic shock. Serum thyroid level findings do not help determine the presence of hypoxemia or metabolic acidosis.
Question 3 of 5
The nurse is caring for a client with shock accompanied by lung congestion. How would the nurse position this client?
Correct Answer: D
Rationale: For a client with shock accompanied by lung congestion, the nurse should raise the client's upper body to approximately $45^{\circ}$ and lower extremities to approximately $15^{\circ}$. Elevating the upper body lowers the diaphragm and provides more room for lung expansion and gas exchange. Elevating the head reduces intracranial pressure. Elevating the legs promotes blood perfusion to the heart, lungs, and brain.
Question 4 of 5
The nurse is caring for a client who is in neurogenic shock. The nurse knows that this is a subcategory of what kind of shock?
Correct Answer: D
Rationale: Three types of distributive shock are neurogenic, septic, and anaphylactic shock. There is no such condition as carcinogenic shock. Obstructive and hypovolemic shock do not have subcategories.
Question 5 of 5
The student nurse is being precepted in the ICU. The student is caring for a client in the compensatory stage of shock who is hypovolemic. Which compensatory mechanism is most important in the re absorption and retention of fluid in the body?
Correct Answer: C
Rationale: Antidiuretic hormone (ADH) and corticosteroid hormones play an active role in controlling sodium and water balance. Both ADH and corticosteroid hormones promote fluid reabsorption and retention. The renin-angiotensin-aldosterone system is a mechanism that restores blood pressure (BP) when circulating volume is diminished. The release of catecholamines stimulates secretion of epinephrine and norepinephrine.
