A nurse in the ICU is caring for a client who has poor cardiac output with heart failure and is receiving a Dopamine drip. The nurse should identify that which of the following findings indicates that the medication is effective?
Decreased blood pressure
Decreased blood glucose level
Increased urine output
Increased respiratory rate
The Correct Answer is C
A. Decreased blood pressure: Dopamine is used to improve cardiac output by increasing heart rate and contractility, which should increase blood pressure. A decreased blood pressure would suggest that the medication is not effective or is causing adverse effects.
B. Decreased blood glucose level: Dopamine does not have a direct role in decreasing blood glucose levels. In fact, it may lead to increased glucose levels due to stress or the body’s response to the medication.Decreased blood glucose is not an indicator of effectiveness.
C. Increased urine output: Dopamine improves renal perfusion by increasing cardiac output, leading to improved kidney function and increased urine output. An increase in urine output is a positive sign that the medication is effectively improving cardiac output and renal perfusion.
D. Increased respiratory rate: An increased respiratory rate is not an indicator of dopamine effectiveness. The primary indicator of dopamine effectiveness is improved renal function, which manifests as increased urine output.

Correct Answer is A
Explanation
A. Asystole: Asystole is defined as the complete absence of electrical and mechanical cardiac activity. The EKG strip displays a flatline, indicating no ventricular depolarization or contraction, which is the hallmark of asystole. This rhythm is a non-shockable cardiac arrest rhythm.
B. Sinus Tachycardia: Sinus tachycardia is a regular rhythm with a heart rate greater than 100 bpm, characterized by clear P waves and QRS complexes. This is clearly not present in the given flatline strip.
C. Sinus Bradycardia: Sinus bradycardia is a regular rhythm with a heart rate less than 60 bpm, characterized by clear P waves and QRS complexes.
D. Supraventricular Tachycardia (SVT): SVT is a rapid rhythm, typically 150-250 bpm, with narrow QRS complexes and often obscured P waves.
