After vomiting 200 mL of bright red blood, a patient develops tachycardia. What are the nurse's priorities?

In a scenario where a patient has vomited a significant amount of bright red blood and is exhibiting tachycardia, the priority is to address the potential loss of blood volume and the associated physiological responses.

Managing bleeding and reassessing vital signs are crucial because they directly relate to the patient's stability. Bright red blood in vomit indicates acute upper gastrointestinal bleeding, which can lead to significant hemodynamic instability. Therefore, monitoring vital signs helps track any changes in the patient's condition. High heart rate, or tachycardia, often signifies compensatory mechanisms in response to reduced blood volume.

Providing intravenous fluids is also essential as they help to restore blood volume and improve circulatory status. IV fluids can help mitigate the effects of hypovolemia and support blood pressure, countering the tachycardic response.

Requesting an order to specifically control tachycardia may not be an immediate priority. The tachycardia is likely a compensatory response to the volume loss rather than a standalone issue needing direct medication intervention at this moment. Addressing the underlying cause (the bleeding) and supporting the patient's hemodynamics through reassessment and IV fluid administration are the priorities in this urgent clinical situation.

Thus, all actions except requesting
