Which finding is often the earliest sign of hypovolemic shock?
A change in mental status, such as anxiety
✓
Mottled skin over the knees
Absent peripheral pulses
No urine output at all
Correct Answer
A change in mental status, such as anxiety
Even a small drop in brain perfusion shows up as anxiety, restlessness or confusion, often before vital signs change much. Mottled skin over the knees appears late, in the refractory stage. Absent peripheral pulses signal advanced shock with severe vasoconstriction or collapse. No urine output at all is a late finding after kidney perfusion has failed.

Question 2
During the compensatory stage of shock, the sympathetic response redirects blood flow mainly toward which organs?
The skin and skeletal muscles
The brain and heart
✓
The stomach and intestines
The kidneys and liver
Correct Answer
The brain and heart
Catecholamines constrict vessels in less essential beds so that the brain and heart keep receiving blood. The skin and skeletal muscles lose flow, which is why the skin becomes cool. The stomach and intestines are underperfused as blood is shunted away from the gut. The kidneys and liver also lose flow, which is why urine output falls.

Question 3
Which patient has a recognized risk factor for sepsis?
A healthy adult with a sprained ankle
A young adult with mild seasonal allergies
An adult receiving chemotherapy for leukemia
✓
An adult with well-controlled acne
Correct Answer
An adult receiving chemotherapy for leukemia
Cancer, leukemia and immunosuppression weaken the body's defenses, so an infection can spread and trigger sepsis. A healthy adult with a sprained ankle has no infection and an intact immune system. A young adult with mild seasonal allergies is not immunocompromised. An adult with well-controlled acne has no condition that raises sepsis risk.

Question 4
In the progressive stage of shock, blood pressure keeps falling even though the heart is racing. Which change in the capillaries drives this?
They constrict and block all flow to the tissues
They pull extra fluid in from the tissues
They rupture and cause external bleeding
They leak fluid and protein into the interstitial space
✓
Correct Answer
They leak fluid and protein into the interstitial space
In the progressive stage, capillary permeability rises sharply, so fluid and protein move out of the vessels into the tissues, worsening hypotension and causing edema and electrolyte imbalance. They constrict and block all flow to the tissues does not describe capillary leak. They pull extra fluid in from the tissues is the opposite of what happens. They rupture and cause external bleeding is not the mechanism of shock progression.
Category: Stages of Shock
Question 5
Which finding indicates that a patient's shock has reached the refractory stage?
Severe hypotension that persists despite fluids and vasopressors
✓
A slightly faster heart rate with a normal blood pressure
Restlessness with a small drop in urine output
Low blood pressure that rises when IV fluid is given
Correct Answer
Severe hypotension that persists despite fluids and vasopressors
The refractory stage is defined by profound hypotension and organ failure that no longer respond to treatment, and recovery is unlikely. A slightly faster heart rate with a normal blood pressure fits the initial stage. Restlessness with a small drop in urine output is an early, subtle sign. Low blood pressure that rises when IV fluid is given shows the patient is still responding, which means the shock is not refractory.

Question 6
Why is an arterial line preferred over a blood pressure cuff for monitoring a patient in shock?
An arterial line lowers the risk of infection
Intense vasoconstriction can make cuff readings inaccurate
✓
A cuff cannot be used with a heart monitor
An arterial line helps raise the blood pressure
Correct Answer
Intense vasoconstriction can make cuff readings inaccurate
Strong sympathetic stimulation narrows peripheral arteries, so a cuff may read falsely, while an arterial line gives continuous, more accurate pressures, including the mean arterial pressure. An arterial line lowers the risk of infection is false, because any invasive line adds infection risk. A cuff cannot be used with a heart monitor is untrue; both are used together routinely. An arterial line helps raise the blood pressure is wrong because it only measures pressure.

Question 7
During prolonged shock, how can bacteria from the patient's own intestine end up in the bloodstream?
Fever makes them multiply until they spill into the blood
Antibiotics drive them out through the bowel wall
Poor blood flow damages the gut lining so they can cross it
✓
Vasopressors carry them from the gut into the veins
Correct Answer
Poor blood flow damages the gut lining so they can cross it
When shock diverts blood away from the gut, the intestinal lining is injured and can let gut bacteria and their toxins pass into the circulation, a process called bacterial translocation that can add infection to shock. Fever makes them multiply until they spill into the blood does not describe how gut bacteria cross the bowel wall. Antibiotics drive them out through the bowel wall is false; antibiotics do not push bacteria out of the intestine. Vasopressors carry them from the gut into the veins is false; vasopressors constrict vessels and do not transport bacteria.
Category: Organ Dysfunction
Question 8
While trending the blood pressure of a patient who is bleeding internally, which pattern warns that hypovolemia is worsening?
A widening pulse pressure
A rising systolic pressure
A slowing heart rate
A narrowing pulse pressure
✓
Correct Answer
A narrowing pulse pressure
As volume falls, systolic pressure drops while vasoconstriction holds the diastolic pressure up, so the gap between them narrows. A widening pulse pressure is linked to other problems, such as rising intracranial pressure. A rising systolic pressure would suggest improvement, not deterioration. A slowing heart rate is not expected in hypovolemia, where the heart speeds up to compensate.

Question 9
For a patient in hypovolemic shock, the nurse raises the legs while keeping the trunk flat instead of tilting the whole bed head-down. Which problem does avoiding the head-down tilt prevent?
Abdominal organs pressing on the diaphragm and hindering breathing
✓
A slowing of the heart rate
Fluid pooling in the legs
IV fluids failing to infuse
Correct Answer
Abdominal organs pressing on the diaphragm and hindering breathing
Raising only the legs helps venous return, while tilting the whole body head-down pushes the abdominal contents against the diaphragm and impairs breathing. A slowing of the heart rate is not an effect of the head-down tilt that positioning is meant to avoid. Fluid pooling in the legs is the opposite of what raising the legs does. IV fluids failing to infuse is not a recognized effect of either position.
Category: Hypovolemic Shock
Question 10
A patient with heart failure is receiving rapid IV fluid for hypovolemic shock. Which assessment detects the main complication of this therapy?
Bowel sounds in all quadrants
Lung sounds for crackles
✓
Pupil size and reaction
Skin for a new rash
Correct Answer
Lung sounds for crackles
A weak heart or diseased kidneys may not handle a large, fast volume load, so fluid can back up into the lungs; crackles and rising respiratory effort signal pulmonary edema and must be reported. Bowel sounds in all quadrants do not reveal fluid overload. Pupil size and reaction track neurologic status, not volume tolerance. Skin for a new rash would look for an allergic reaction, not overload.
Category: Volume Resuscitation
Question 11
A patient in hypovolemic shock from a bleeding ulcer has a falling hemoglobin. Which fluid restores oxygen-carrying capacity?
Normal saline
Lactated Ringer's solution
Packed red blood cells
✓
Albumin
Correct Answer
Packed red blood cells
When blood loss causes the shock, red cells must be replaced to carry oxygen to the tissues. Normal saline restores volume but carries no oxygen and dilutes the remaining red cells. Lactated Ringer's solution is a crystalloid that also restores volume without oxygen-carrying capacity. Albumin is a colloid that draws fluid into the vessels but contains no red cells.
Category: Volume Resuscitation
Question 12
Without invasive monitoring, which finding shows that volume resuscitation for hypovolemic shock is improving perfusion?
The skin has become cool and clammy
The heart rate keeps climbing
The patient reports growing thirst
Anxiety is easing and peripheral pulses have returned
✓
Correct Answer
Anxiety is easing and peripheral pulses have returned
Calmer mentation reflects better brain perfusion, and palpable distal pulses show that blood is reaching the periphery again. The skin has become cool and clammy is a sign of ongoing vasoconstriction and poor perfusion. The heart rate keeps climbing suggests continued compensation for low volume. The patient reports growing thirst indicates the body still senses a fluid deficit.

Question 13
A patient in hemorrhagic shock is receiving several units of stored red cells in quick succession. Which measure keeps the transfusions from lowering the patient's core temperature?
Running each unit through an approved warming device
✓
Slowing each unit to a keep-vein-open rate
Hanging each unit straight from refrigerated storage
Giving each unit through a smaller IV catheter
Correct Answer
Running each unit through an approved warming device
Blood is stored cold, and infusing many cold or room-temperature units quickly can drop the core temperature into hypothermia, so a blood warmer is used during rapid transfusion. Slowing each unit to a keep-vein-open rate would deny a bleeding patient the volume needed. Hanging each unit straight from refrigerated storage is exactly what causes the temperature to fall. Giving each unit through a smaller IV catheter slows flow and does nothing to warm the blood.
Category: Volume Resuscitation
Question 14
Which findings are expected in the early, warm phase of septic shock?
Cool, mottled skin with weak pulses
Warm, flushed skin with bounding pulses
✓
Pale skin with a slow heart rate
Cyanotic lips with absent pulses
Correct Answer
Warm, flushed skin with bounding pulses
Early septic shock is a hyperdynamic state: vasodilation lowers vascular resistance, cardiac output rises, and the skin is warm with bounding pulses. Cool, mottled skin with weak pulses describes the late, cold phase. Pale skin with a slow heart rate does not fit sepsis, which causes tachycardia. Cyanotic lips with absent pulses suggest circulatory collapse.
Category: Septic Shock
Question 15
Why does the nurse check blood glucose frequently in a patient with septic shock?
Low glucose is the earliest sign that sepsis is starting
Glucose readings show which organism is causing the infection
Sepsis can push glucose too high or too low
✓
Antibiotics for sepsis contain large amounts of sugar
Correct Answer
Sepsis can push glucose too high or too low
Stress hormones and insulin resistance can drive glucose up, while the illness can also cause low glucose, and both extremes are linked with worse outcomes, so glucose is checked often and treated to keep it stable. Low glucose is the earliest sign that sepsis is starting is false; mental status and vital sign changes are typical early cues. Glucose readings show which organism is causing the infection is false; cultures identify the organism. Antibiotics for sepsis contain large amounts of sugar is not the reason for monitoring.
Category: Septic Shock
Question 16
A patient in septic shock receives a medication to prevent stress ulcers. What makes this patient prone to them?
Antibiotics directly erode the stomach wall
Fever greatly increases stomach acid output
Bed rest slows the emptying of the stomach
Reduced blood flow injures the stomach lining
✓
Correct Answer
Reduced blood flow injures the stomach lining
In shock, blood is diverted away from the gut, and the poorly perfused stomach lining loses its protective defenses, so stress ulcer prevention is part of sepsis care. Antibiotics directly erode the stomach wall is not the mechanism of stress ulcers. Fever greatly increases stomach acid output is not the cause. Bed rest slows the emptying of the stomach does not explain mucosal injury from hypoperfusion.
Category: Septic Shock
Question 17
A patient with sepsis had rapid breathing for several shifts, but the respiratory rate is now slowing while the serum lactate keeps rising. What does this suggest?
The patient is tiring and decompensating
✓
The metabolic acidosis is resolving
The infection is clearing
The patient's anxiety has improved
Correct Answer
The patient is tiring and decompensating
Rapid breathing compensates for metabolic acidosis by blowing off carbon dioxide; when the rate falls while lactate climbs, the patient can no longer keep up and is deteriorating. The metabolic acidosis is resolving does not fit a rising lactate. The infection is clearing would bring falling lactate and stabilizing vital signs. The patient's anxiety has improved does not explain a worsening acid-base picture.
Category: Septic Shock
Question 18
Why does the nurse take special care when suctioning a patient in neurogenic shock?
Suctioning raises the blood pressure to dangerous levels
Suctioning can stimulate the vagus nerve and slow the heart further
✓
Suctioning causes the spinal cord injury to extend
Suctioning triggers a rise in body temperature
Correct Answer
Suctioning can stimulate the vagus nerve and slow the heart further
With sympathetic input lost, vagal stimulation from suctioning is unopposed and can cause profound bradycardia, so atropine is kept readily available. Suctioning raises the blood pressure to dangerous levels is not the expected effect in neurogenic shock. Suctioning causes the spinal cord injury to extend is not a recognized risk of airway suctioning. Suctioning triggers a rise in body temperature is not a recognized effect.
Category: Neurogenic Shock
Question 19
A patient in neurogenic shock is hypothermic and hemodynamically unstable. How should rewarming be done?
Rapidly, with hot packs placed on the chest
Not at all, because cooling protects the spinal cord
Gradually, because rapid warming can worsen vasodilation
✓
Rapidly, by infusing heated fluids at a high rate
Correct Answer
Gradually, because rapid warming can worsen vasodilation
Rewarming is done slowly, with a warming blanket, because rapid rewarming dilates the vessels further and can deepen the hypotension and hemodynamic instability. Rapidly, with hot packs placed on the chest risks both burns and worsening vasodilation. Not at all, because cooling protects the spinal cord leaves the patient exposed to the harms of hypothermia. Rapidly, by infusing heated fluids at a high rate combines fast rewarming with a risk of fluid overload.
Category: Neurogenic Shock
Question 20
After a spinal cord injury, which finding reflects spinal shock rather than neurogenic shock?
Hypotension from loss of vascular tone
Bradycardia from unopposed vagal activity
Warm, flushed skin from vasodilation
Flaccid paralysis with loss of reflexes below the injury
✓
Correct Answer
Flaccid paralysis with loss of reflexes below the injury
Spinal shock is a temporary neurologic syndrome of flaccid muscles and absent reflexes below the injury, and function may return. Hypotension from loss of vascular tone is a hemodynamic feature of neurogenic shock. Bradycardia from unopposed vagal activity also belongs to neurogenic shock. Warm, flushed skin from vasodilation is another sign of neurogenic shock.
