Final answer:
No, an IV rate of 500 cc/hr should not be used for a patient with decreased ability to pump blood in cardiogenic shock as it could worsen their condition. Fluid management would need to be more conservative and adapted to the patient's specific hemodynamic status.
Step-by-step explanation:
To answer the question, whether an IV rate of 500 cc/hr should be used in a patient with decreased ability to pump blood in cardiogenic shock, the answer is B) No. In cases of cardiogenic shock, where the heart's ability to pump blood is impaired, careful fluid management is critical. Administering fluids at too high of a rate can increase the workload on an already struggling heart, possibly worsening the patient's condition. A more conservative fluid administration rate may be chosen based on the patient's hemodynamic status and closely monitored by the medical team. In the reference scenario provided, concerning the emergency room situation, an aide would indeed retrieve an IV bag containing the prescribed 0.5% KCl solution to treat a patient's hypokalemia. This is a different scenario than treating cardiogenic shock, where fluid management would differ based on the specifics of the patient's cardiovascular status.
