What is the primary goal of drug therapy in shock?

• Decrease heart rate

• Restore adequate tissue perfusion

• Lower blood pressure

• Reduce respiratory rate

Which class of medications is commonly used to treat hypotension in shock?

• Antihypertensives

• Vasopressors

• Beta blockers

• Diuretics

Dobutamine primarily stimulates which type of receptors?

• Alpha-1

• Beta-1

• Beta-2

• Dopamine

What is the primary effect of norepinephrine in shock management?

• Bronchodilation

• Vasodilation

• Vasoconstriction and increased blood pressure

• Diuresis

Which of the following is a compensatory mechanism in early shock?

• Decrease cardiac output

• Bronchoconstriction

• Vasoconstriction and increased heart rate

• Hypoglycemia

Which type of shock is characterized by severe allergic reaction?

• Hypovolemic shock

• Cardiogenic shock

• Neurogenic shock

• Anaphylactic shock

Which drug is often used to treat anaphylactic shock?

• Dobutamine

• Epinephrine

• Dopamine

• Atropine

A patient in septic shock may be treated with which of the following?

• Vasopressin

• Antibiotics and norepinephrine

• Beta blockers

• Calcium channel blockers

What is a key nursing assessment when administering vasopressors?

• Monitor blood glucose

• Monitor blood pressure and perfusion

• Check for bradycardia

• Assess bowel sounds

Dopamine has a dose-dependent effect. Low doses primarily:

• Stimulate alpha receptors

• Improve renal perfusion

• Cause vasoconstriction

• Decrease urine output
