A nurse working on a medical-surgical unit is notified about a mass casualty event that recently took place in the community.
Which of the following assignments should the nurse anticipate?
Assist in discharging stable clients to home.
Determine the acuity and number of casualties arriving at the facility.
Delegate tasks to emergency health care specialists.
Provide informational updates to members of the media.
The Correct Answer is B
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.

Correct Answer is C
Explanation
The correct answer is choice C: Increase rate of ventilation.
Choice A rationale:
Decreasing expiratory flow time would not directly address the elevated PaCO2 levels. This intervention is more related to managing expiratory phase issues rather than correcting respiratory acidosis.
Choice B rationale:
Decreasing expiratory pressure might help with certain ventilation issues, but it does not specifically target the elevated PaCO2 and resulting acidosis.
Choice C rationale:
Increasing the rate of ventilation helps to blow off more CO2, thereby reducing PaCO2 levels and correcting the respiratory acidosis indicated by the pH of 7.26 and PaCO2 of 68 mm Hg.
Choice D rationale:
Increasing the ventilator tidal volume could also help reduce PaCO2 by increasing the amount of air exchanged with each breath. However, increasing the rate of ventilation is generally a more immediate and effective intervention for acute respiratory acidosis.
Correct Answer is C
Explanation
Choice A rationale:
A bottle is generally much better than using a pacifier. This statement is not accurate. Prolonged bottle use, especially with sugary liquids like milk, can have adverse effects on a child's dental health. It can lead to an increased risk of cavities, similar to prolonged pacifier use.
Choice B rationale:
The bottle will assist in preventing thumb sucking. This statement is incorrect. While a bottle may provide comfort to a child, it does not prevent thumb sucking. Thumb sucking is a separate behavior that may also have dental implications if it persists beyond a certain age.
Choice C rationale:
Prolonged bottle use can increase the risk for cavities. This response is correct. Prolonged bottle use, especially with milk or sugary beverages, can expose the child's teeth to prolonged contact with sugars, increasing the risk of cavities. It's important for the nurse to educate the mother about the potential dental risks associated with extended bottle use.
Choice D rationale:
Using milk rather than juice helps to avoid tooth decay. While milk is generally considered a healthier choice than juice, the key issue in this scenario is the prolonged use of the bottle, regardless of its content. Prolonged bottle use with any liquid, including milk, can still increase the risk of cavities.
