A nurse in an assisted-living facility is reinforcing teaching with staff members about preparing for an external chemical disaster. Which of the following instructions should the nurse include?
"Turn on fans in the facility to circulate air."
"Cover the electrical outlets with wet towels."
"Move clients to a room above ground with few windows."
"Open the fireplace dampers in the day room."
The Correct Answer is C
During an external chemical disaster, it is crucial to minimize the exposure of clients to the hazardous substance. Moving clients to a room above ground level with few windows can help reduce the risk of exposure to the chemical and its fumes. This is because many hazardous chemicals tend to be denser than air and may settle closer to the ground. Choosing a room above ground level and with fewer windows can provide a safer environment.
Turning on fans in the facility to circulate air can actually worsen the situation by spreading the chemical and its fumes throughout the facility, potentially exposing more individuals.
Covering the electrical outlets with wet towels is not directly related to preparing for an external chemical disaster. It may be more relevant during a fire emergency to prevent the spread of flames, but not for chemical exposure.
Opening the fireplace dampers in the day room can allow the entry of outside air and potentially introduce more of the hazardous substance into the facility.

Correct Answer is C
Explanation
a.Applying the restraint under the client's clothes: Restraints should be applied over the client's clothes to avoid direct skin contact and reduce the risk of skin irritation or injury.
b.Tying the restraint to the railing of the client's bed: Restraints should not be tied to bed rails or any other fixed objects. This can increase the risk of injury to the client and should be avoided.
c.Placing the client in a sitting position is appropriate when applying a belt restraint, as it helps prevent respiratory compromise and allows the client to maintain a safer and more comfortable posture.
d.A belt restraint should be placed around the client's waist, not across the chest, to avoid restricting breathing.
Correct Answer is D
Explanation
Hyperkalemia refers to an elevated level of potassium in the blood. It can have various manifestations, and one of the critical effects of hyperkalemia is its impact on cardiac function. High levels of potassium can disrupt the normal electrical conduction in the heart, leading to arrhythmias or irregular heart rate. These arrhythmias can range from mild palpitations to more severe and life-threatening conditions like ventricular fibrillation.
Dry mucous membranes are more commonly associated with dehydration or reduced fluid intake. Hyperkalemia does not directly cause dry mucous membranes.
Trousseau's sign is a clinical manifestation of hypocalcemia, not hyperkalemia. It is characterized by carpal spasm induced by inflating a blood pressure cuff above the client's systolic blood pressure for a few minutes.
Hyperactive reflexes are commonly seen in conditions such as hyperthyroidism or certain neurologic disorders. They are not directly related to hyperkalemia.
