A nurse in an assisted-living facility reinforcing teaching with staff members about preparing for an external chemical disaster. Which of the following instructions should the nurse include?
"Open the fireplace dampers day room."
"Move clients to a room above ground with few windows."
"Turn on fans in the facility to circulate air."
"Cover the electrical outlets with wet towels."
The Correct Answer is B
A) Open the fireplace dampers in the day room:
Opening the fireplace dampers in the event of an external chemical disaster would not be appropriate. In fact, this could allow toxic air or chemicals to enter the facility. It is important to seal off ventilation points that might allow the chemicals to enter, such as windows, doors, and any other openings, rather than opening the dampers.
B) Move clients to a room above ground with few windows:
In the event of an external chemical disaster, moving clients to a room above ground with few windows is a key safety measure. Rooms that are above ground level tend to be safer in such situations because chemicals may settle at ground level, increasing exposure risks to those below ground. A room with few windows is also important because it minimizes potential entry points for toxic substances from outside. The focus is on containing the air supply and limiting exposure to harmful agents.
C) Turn on fans in the facility to circulate air:
Turning on fans in the facility during a chemical disaster could worsen the situation by spreading toxic air or chemicals throughout the building. Fans are generally used to circulate air, but in this context, they would not be helpful and could potentially increase exposure to harmful substances. Instead, the focus should be on reducing airflow from the outside and sealing off the building.
D) Cover the electrical outlets with wet towels:
Covering electrical outlets with wet towels is not an effective response to an external chemical disaster. While wet towels can be useful in some scenarios for filtering or protecting from certain substances, in a chemical disaster, the priority is to ensure proper ventilation control and to protect from airborne chemicals by sealing the room. Electrical outlets should be covered for safety only when there is a risk of electrical hazards, but not necessarily in the case of a chemical disaster unless there is specific concern about sparks or fire.

Correct Answer is A
Explanation
A) Request an x-ray of the neck: In cases of suspected epiglottitis, a lateral neck x-ray can help confirm the diagnosis by showing the classic "thumbprint sign," which indicates swelling of the epiglottis. This is a critical diagnostic step, but it should only be performed in a controlled setting where the child’s airway can be monitored closely. The priority is to avoid any procedures that may cause irritation or further compromise the airway.
B) Monitor urine for protein: Monitoring urine for protein is not relevant to the management of epiglottitis. This condition is related to inflammation and obstruction of the upper airway, and the focus should be on respiratory management rather than renal function.
C) Obtain a nasopharyngeal swab: While obtaining a nasopharyngeal swab can help identify the organism causing an infection (often bacterial), it is not the immediate priority in a child with suspected epiglottitis. The child’s airway is the most critical concern, and diagnostic interventions that could potentially cause further distress or obstruction (such as swabbing) should be avoided until airway management is stable.
D) Administer fluconazole: Fluconazole is an antifungal medication, and its use is not appropriate for epiglottitis. Epiglottitis is most often caused by a bacterial infection, particularly Haemophilus influenzae type b (Hib), which requires antibiotic therapy, not antifungals.
Correct Answer is D
Explanation
A) I have a difficult time getting my child to eat green vegetables: While it’s common for preschoolers to be selective about food, especially vegetables, this issue does not represent an immediate concern for the child’s health or development. This issue can often be addressed with strategies to encourage healthy eating, but it is not as urgent as other concerns.
B) My child continually asks me the same questions: Repetitive questioning is a normal part of preschool development, as children at this age are curious and often seek reassurance. It reflects their cognitive development as they try to understand the world around them. While it may be tiring for the guardian, it is not an immediate concern.
C) My child still wets the bed at least two times per week: Bedwetting (enuresis) is common among preschool-aged children, and many children do not gain full bladder control until after age 5. This issue is typically addressed if it continues past the age of 5, but it is not a priority at this time.
D) I have noticed that my child is withdrawn since we switched day care providers: This statement indicates a potential emotional or behavioral issue that requires immediate attention. Changes in behavior, such as withdrawal, can be a sign of stress, anxiety, or difficulty adjusting to a new environment. The nurse should prioritize this concern, as it may indicate that the child is having difficulty coping with the transition and may need additional support or evaluation. Addressing emotional well-being is a priority for the nurse.
