The nurse is treating a client who is experiencing cardiac symptoms of shock. Which medication does the nurse anticipate because of its ability to increase the force of myocardial contraction?
1. Crystalloids
2. Colloids
3. Inotropic drugs
4. Vasopressors
3
Rationale 1: Crystalloids increase volume in the system. Cardiogenic shock is related to the force of myocardial contraction.
Rationale 2: Colloids increase volume in the cardiovascular system. Cardiogenic shock is related to the force of myocardial contraction.
Rationale 3: Inotropic drugs, also called cardiotonic drugs, have the potential to reverse the cardiac symptoms of shock by increasing the force of myocardial contraction.
Rationale 4: Vasopressors increase the blood return to the heart but do not increase the force of myocardial contraction.
Global Rationale: Cardiogenic shock is usually noted with a history of cardiac disease or inadequate force of myocardial contraction. Inotropic drugs, also called cardiotonic drugs, have the potential to reverse the cardiac symptoms of shock by increasing the force of myocardial contraction.
