A patient who has neurogenic shock is receiving a dobutamine infusion through a right forearm IV. Which assessment finding obtained by the nurse indicates a need for immediate action?

The patient's IV infusion site is cool and pale.

The patient's extremities are warm and dry.

The patient's urine output is 28 ml, over the past hour.

The patient's heart rate is 58 beats/min.

Answer and Explanation

The Correct Answer is A

A. In a patient receiving a dobutamine infusion, which is a vasopressor medication used to increase cardiac output, a cool and pale IV infusion site could indicate inadequate perfusion despite treatment. This finding requires immediate action to assess the patient's hemodynamic status and ensure adequate tissue perfusion.

B. Warm and dry extremities are typically indicative of adequate tissue perfusion. In neurogenic shock, vasodilation can lead to warm extremities due to decreased systemic vascular resistance. While this finding may be expected in neurogenic shock, it does not necessarily indicate a need for immediate action if other parameters are stable.

C. Decreased urine output can be indicative of inadequate renal perfusion and impaired kidney function. In a patient with neurogenic shock, maintaining adequate renal perfusion is crucial to prevent acute kidney injury. While decreased urine output warrants close monitoring and intervention, it may not require immediate action unless other signs of worsening perfusion are present.

D. A heart rate of 58 beats/min may be within the normal range for some patients, especially those who are receiving dobutamine, which can have a chronotropic effect. However, in the context of neurogenic shock, bradycardia may indicate a compensatory response to hypotension and decreased tissue perfusion. While bradycardia alone may not always require immediate action, it should prompt further assessment of the patient's hemodynamic status and response to treatment.

Correct Answer is A

Explanation

A. Elective cardioversion involves the synchronized delivery of a therapeutic electrical shock to the heart to restore normal sinus rhythm in a patient with a tachyarrhythmia, such as atrial fibrillation or atrial flutter. However, ventricular tachycardia (VT) is a life-threatening arrhythmia characterized by a rapid heart rate originating from the ventricles, and it requires immediate intervention due to the risk of deteriorating into ventricular fibrillation (VF) and cardiac arrest. Therefore, elective cardioversion is not appropriate for treating VT.

B. Defibrillation involves the unsynchronized delivery of a high-energy electrical shock to the heart to terminate life-threatening arrhythmias, such as ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT). In the case of a conscious patient with pulse-sustaining ventricular tachycardia, immediate defibrillation may not be necessary. However, if the patient deteriorates into pulseless VT or VF, prompt defibrillation is required to restore normal cardiac rhythm and circulation.

C. Radiofrequency catheter ablation is a procedure performed in a cardiac catheterization lab to treat certain cardiac arrhythmias by delivering radiofrequency energy to the specific area of the heart responsible for the abnormal rhythm. While radiofrequency catheter ablation may be considered for certain types of sustained ventricular tachycardia that are refractory to medical therapy or deemed to be originating from a specific site in the heart, it is not the immediate intervention for hemodynamically unstable ventricular tachycardia.

D. CPR is an emergency procedure performed on individuals experiencing cardiac arrest or a life- threatening medical emergency. In the case of ventricular tachycardia (VT) with a pulse, the patient is still perfusing, and CPR is not indicated. However, if the patient deteriorates into pulseless VT or ventricular fibrillation (VF), CPR may be initiated along with immediate defibrillation.

A. Provide 02 at 100% per non-rebreather mask. B. Initiate continuous electrocardiogram (ECG) monitoring C. Draw blood to type and crossmatch for transfusions. D. Insert two large-bore IV catheters.

Correct Answer is A

Explanation

A The first intervention should be to ensure adequate oxygenation, as hypoxia can exacerbate shock. Therefore, providing oxygen at 100% via a non-rebreather mask is the most critical initial step. This intervention helps to maximize the amount of oxygen delivered to the patient's lungs and subsequently to the rest of the body, supporting vital organ function while further assessments and interventions are prepared.

B Continuous ECG monitoring allows for the assessment of the patient's heart rhythm, rate, and any signs of dysrhythmias or cardiac ischemia. This intervention is important for detecting any life- threatening arrhythmias, such as ventricular tachycardia or fibrillation, which may require immediate intervention. While ECG monitoring is important, it may not be the highest priority intervention.

C Drawing blood for type and crossmatch is important for preparing for potential blood transfusions if significant blood loss is suspected. However, this intervention may take some time to process, and immediate stabilization of the patient's condition is paramount.

D Large-bore IV catheters allow for rapid infusion of fluids to restore intravascular volume and improve tissue perfusion. This intervention is critical for stabilizing the patient's hemodynamic status and takes precedence in the management of shock. However, oxygenation should take priority.
