What is the goal of treatment for the client diagnosed with cardiogenic shock?
Control dysrhythmias and decrease the heart rate
Decrease cardiac workload and increase systemic perfusion
Improve oxygen exchange and decrease urinary output
Decrease the blood pressure and respiratory rate
The Correct Answer is B
A. Control dysrhythmias and decrease the heart rate
Controlling dysrhythmias is important, but decreasing heart rate is not always the goal, as a compensatory tachycardia may be necessary for perfusion.
B. Decrease cardiac workload and increase systemic perfusion
Cardiogenic shock results from impaired cardiac output. The goal is to reduce the heart’s workload (e.g., by reducing afterload) while improving systemic perfusion.
C. Improve oxygen exchange and decrease urinary output
Oxygenation is important, but decreased urinary output indicates poor renal perfusion and worsening shock, which is not a goal of treatment.
D. Decrease the blood pressure and respiratory rate
In cardiogenic shock, blood pressure is already low. The goal is to maintain adequate perfusion, not to further reduce BP.

Correct Answer is D
Explanation
A. Elevate the extremity and apply an ice pack to the injured area
Elevating the extremity can help reduce swelling, but applying ice is not recommended for chemical burns as it can cause further tissue damage.
B. Contact poison control to determine the best neutralizing agent
While contacting poison control is important, it should not be the immediate first action in an emergency setting.
C. Apply a sterile dressing, wrapping the fingers separately
This is important for protecting the wound, but it is not the immediate first action needed for chemical burns.
D. Irrigate the affected area with room temperature water
Immediate irrigation with room temperature water helps to remove the chemical from the skin and dilute its effect, which is the first critical step in managing a chemical burn.
