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.

Related Questions
Correct Answer is ["C","D","E"]
Explanation
A. Color of conjunctiva
While assessing for signs of perfusion is important, conjunctival color is not a primary assessment for norepinephrine administration. Perfusion is better assessed through blood pressure, heart rate, capillary refill, and urine output.
B. Deep tendon reflexes
Norepinephrine primarily affects vascular tone and cardiac output. Deep tendon reflexes are not a priority assessment for this medication.
C. IV Insertion site
Norepinephrine is a vasopressor, and extravasation can cause severe tissue necrosis. Frequent monitoring of the IV site is necessary to prevent complications.
D. Blood pressure and heart rate
Norepinephrine increases blood pressure and heart rate through vasoconstriction. Continuous monitoring is required to assess for excessive hypertension, tachycardia, or inadequate response to therapy.
E. Hourly urine output
Urine output is an essential indicator of organ perfusion. Since norepinephrine is used to maintain adequate blood pressure and perfusion in septic shock, monitoring urine output helps assess the effectiveness of treatment.
Correct Answer is C
Explanation
A. Inability to understand directions
The client's issue is with motor coordination, not comprehension.
B. Lesion of cranial nerve IX
Cranial nerve IX (Glossopharyngeal) is associated with swallowing and taste, not motor coordination.
C. Dysfunction of the cerebellum
The cerebellum controls coordination and fine motor movements. The client's inability to perform rapid alternating movements (dysdiadochokinesia) suggests cerebellar dysfunction.
D. Vestibular disease
Vestibular disorders cause dizziness, vertigo, and balance problems but do not typically affect rapid alternating movements.
