A nurse and a newly licensed nurse are providing care for a client who has distributive shock. How should the nurse explain the pathophysiology of distributive shock to the newly licensed nurse?
"Distributive shock occurs due to increased systemic vascular resistance."
"Distributive shock occurs due to systemic vasodilation."
"Distributive shock occurs due to loss of myocardial contractility."
"Distributive shock occurs due to loss of blood volume."
The Correct Answer is B
A. Increased systemic vascular resistance is typically associated with hypovolemic or cardiogenic shock, not distributive shock.
B. Distributive shock is characterized by systemic vasodilation, which leads to a decrease in systemic vascular resistance and results in inadequate tissue perfusion despite normal or increased cardiac output.
C. Loss of myocardial contractility is related to cardiogenic shock, not distributive shock.
D. Loss of blood volume is a characteristic of hypovolemic shock, whereas distributive shock occurs even when blood volume is normal due to vasodilation.

Correct Answer is A
Explanation
A. Stridor is a high-pitched sound indicating upper airway obstruction and is a critical sign of anaphylaxis requiring immediate intervention to secure the airway.
B. Hypotension is a serious condition that occurs during anaphylaxis, but the priority is to address the airway obstruction first.
C. Urticaria (hives) is a common symptom of an allergic reaction but is not life-threatening and can be addressed after more severe symptoms.
D. Vomiting may occur during anaphylaxis but is not the most urgent finding when airway compromise is present.
Correct Answer is B
Explanation
A. Flushing of the skin is not typical in hypovolemic shock; rather, the skin is usually cool and clammy due to vasoconstriction.
B. Oliguria, or decreased urine output, is expected in hypovolemic shock as the kidneys receive less blood flow, leading to reduced urine production.
C. Bradypnea is not a common finding in hypovolemic shock; instead, tachypnea (increased respiratory rate) is typically observed due to compensatory mechanisms for hypoxia and acidosis.
D. Hypertension is not expected in hypovolemic shock; instead, the client typically presents with hypotension due to decreased blood volume and pressure.
