What should be done once the SBP reaches 100 mmHg or greater in a patient with CHF?

When managing a patient with congestive heart failure (CHF), monitoring vital signs, including blood pressure, is crucial. Once the systolic blood pressure (SBP) reaches 100 mmHg or greater, it indicates that the patient's hemodynamic status has improved to some extent and allows for further assessment and intervention.

At this point, the appropriate response is to treat the specific conditions according to the patient's presenting symptoms. For CHF, this may involve addressing any pulmonary edema or chest pain that may be present. This treatment can include the administration of diuretics for fluid overload, nitrates for chest pain, or other supportive measures tailored to the patient’s condition. Providing interventions aimed specifically at CHF and its complications is essential in optimizing the patient's outcome.

Continuing current treatment without reassessing the patient's needs might neglect specific interventions that could significantly improve the patient's condition. Transferring to advanced care is not immediately necessary unless the patient deteriorates or requires interventions beyond the scope of initial management. Administering additional fluids could be counterproductive, as patients with CHF often have fluid overload, which can worsen their condition rather than improve it.

Thus, option B is the most suitable approach as it focuses on effectively managing the patient's current state and any related issues.
