Deck 9: Shock

Question 1

How does the intraaortic balloon pump (IABP)assist a patient who is in cardiogenic shock to increase cardiac output?

A) Provides generalized vasoconstriction.
B) Inflates during the diastole phase.
C) Constricts the vena cava.
D) Adds hypertonic fluid to the circulating volume.

Answer 1

Inflates during the diastole phase.

Question 2

A nurse explains that the minimal acceptable hourly urine output for a patient in shock who weighs 220 lb is ______ mL.(Use numeric characters only.)

Answer 2

50

Question 3

A nurse is explaining to a family member the pathophysiologic characteristic of distributive shock.What information should the nurse include?

A) The intravascular compartment fills beyond capacity, allowing fluid to leak out, compressing vital organs.
B) The circulating volume causes excessive constriction of the vessels, causing blood pooling.
C) Widely fluctuating blood pressures stimulate vascular collapse, causing severe alterations in peripheral perfusion.
D) Although the circulating volume is intact, excessive vascular dilation causes drastic drops in the blood pressure.

Answer 3

Although the circulating volume is intact, excessive vascular dilation causes drastic drops in the blood pressure.

A) Excess cardiac output, related to hypertension
B) Excess cardiac output, related to hypotension
C) Inadequate cardiac output, related to hypovolemia
D) Inadequate cardiac output, related to hypertension

Question 5

A nurse explains that pericardial tamponade and tension pneumothorax can place the patient at risk for ______ shock.

Question 6

Question 7

While shopping in the mall, a nurse sees a lady suddenly fall to the floor.On immediate assessment, the nurse realizes she is not in cardiac arrest and has no need for cardiopulmonary resuscitation (CPR).What should be the immediate actions by the nurse?

A) Check the pulse and respirations and call for a blood pressure cuff.
B) Check the pulse, respirations, skin color, and temperature.
C) Call for help and check the pulse, respiration, and mental status.
D) Ask someone to help place large blankets or coats under her legs and trunk.

Question 8

A nurse is explaining the rationale behind the use of hypothermic devices to a patient's family.When relaying information what explanation should the nurse provide when asked why this garment is used?

A) To improve neurologic recovery.
B) Decreases internal hemorrhage.
C) Warms the patient to create less metabolic demand.
D) Applies pressure during the systole phase and relax pressure during the diastole phase.

Question 9

A nurse is assessing a patient who is in shock.What should the nurse be aware that one common sign will be, regardless of the cause of the shock?

A) The skin is cool and dry with cyanotic nail beds.
B) The skin is cool and moist with cyanotic nail beds.
C) The nail beds are reddened, and the skin is moist and warm.
D) The nail beds are reddened, and the skin is dry and warm.

A) Fowler
B) Trendelenburg
C) Gravity neutral
D) Side lying

Question 11

A) 4
B) 6
C) 14
D) 24

A) Anaphylaxis
B) Respiratory alkalosis
C) Multiple organ dysfunction syndrome (MODS)
D) Neurogenic shock

Question 13
