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 C
Explanation
A) Sit in a hot tub for 30 min every evening:
While a warm bath or hot tub may provide temporary relief for some types of pain, it is not generally recommended during pregnancy, especially in the later stages, because prolonged exposure to hot water can raise the body's core temperature. This could pose a risk to both the mother and fetus, especially at 34 weeks of gestation. It is safer to use warm compresses or baths for shorter durations.
B) Raise chairs to keep knees lower than hips:
This recommendation is incorrect. For relieving lower back pain, it is better for the knees to be slightly higher than the hips when sitting. This posture helps to alleviate strain on the lower back by reducing pressure on the spine. Sitting with the knees lower than the hips can actually exacerbate lower back pain.
C) Perform pelvic rocking exercises several times per day:
Pelvic rocking exercises are an excellent recommendation for relieving lower back pain during pregnancy. These exercises involve gently rocking the pelvis forward and backward, which can help to strengthen the lower back muscles, relieve tension, and improve posture. They are specifically beneficial in alleviating discomfort during pregnancy, particularly at 34 weeks of gestation.
D) Use the arms to pick up heavy items:
While using the arms instead of the back is generally a good practice for avoiding strain, this advice does not directly address the specific issue of lower back pain during pregnancy. Pregnant clients should be advised to avoid lifting heavy objects whenever possible, as the added weight can exacerbate back pain. Safe body mechanics, such as squatting down to pick up objects and using leg muscles rather than back muscles, are also important.
Correct Answer is D
Explanation
A) Weight loss: Weight loss is not a typical manifestation of nicotine withdrawal. While some individuals may experience changes in appetite, particularly an increase in appetite leading to weight gain, weight loss is not a common symptom associated with quitting smoking.
B) Diaphoresis: Diaphoresis, or excessive sweating, is not typically associated with nicotine withdrawal. While some individuals may experience mild symptoms like irritability or nervousness, sweating is not a prominent feature of withdrawal from nicotine.
C) Diarrhea: Diarrhea is not a characteristic symptom of nicotine withdrawal. Some gastrointestinal disturbances such as constipation or changes in appetite may occur, but diarrhea is not a common withdrawal symptom.
D) Insomnia: Insomnia is a well-documented symptom of nicotine withdrawal. Nicotine has stimulating properties, and when an individual stops using nicotine, they may experience difficulty sleeping. This can lead to trouble falling or staying asleep and is a common part of the withdrawal process.
