A nurse is caring for a client who is requesting to go to the bathroom immediately after a vaginal birth. Which of the following actions should the nurse take?

Choice A rationale:

Assisting in discharging stable clients to home is not the most appropriate assignment when a mass casualty event has occurred. During such events, resources are needed for critically injured patients, and stable clients can typically be discharged by non-emergency staff.

Choice B rationale:

Determining the acuity and number of casualties arriving at the facility is the most appropriate assignment during a mass casualty event. This information is critical for allocating resources and providing the necessary level of care to those affected.

Choice C rationale:

Delegating tasks to emergency healthcare specialists may be necessary, but it is not the initial assignment for the nurse working on a medical-surgical unit. Assessing the situation and determining the acuity of incoming casualties take precedence.

Choice D rationale:

Providing informational updates to members of the media is not the role of a nurse during a mass casualty event. This task should be handled by hospital public relations or designated spokespersons to ensure accurate and controlled information dissemination.

Choice A rationale:

The combination of trimethoprim and sulfamethoxazole has a synergistic effect, which means that the two drugs work together to inhibit bacterial growth more effectively than either drug alone. This combination is commonly used to treat urinary tract infections (UTIs) caused by susceptible bacteria.

Choice B rationale:

The combination of trimethoprim and sulfamethoxazole does not have an additive effect that reduces the dosage and frequency of administration of each drug. Instead, it is prescribed as a fixed combination with specific dosages of each drug.

Choice C rationale:

The combination of trimethoprim and sulfamethoxazole does not have an antagonistic effect that prevents the development of resistance to either drug. In fact, the combination is chosen because it covers a broader spectrum of bacteria and reduces the likelihood of resistance development.

Choice D rationale:

The combination of trimethoprim and sulfamethoxazole does not have a selective effect that targets only the bacteria causing the UTI and spares the normal flora. It affects a wide range of bacteria, including both pathogenic and normal flora.
