A provider orders potassium chloride, 20 mEq, orally, once daily.
The nurse knows that the abbreviation mEq stands for which of the following?
Modified equivalents.
Megaequivalents.
Milliequivalents.
Miniequivalents.
The Correct Answer is C
Choice A rationale:
Modified equivalents. This is not the correct answer. The abbreviation "mEq" stands for milliequivalents, not modified equivalents.
Choice B rationale:
Megaequivalents. This is not the correct answer. "Mega" is a prefix indicating a factor of one million. In the context of electrolytes and medications, milliequivalents (mEq) are the appropriate unit of measurement, not megaequivalents.
Choice C rationale:
Milliequivalents. This is the correct answer. Milliequivalents (mEq) are a measure of the chemical combining power of a substance. In medical contexts, mEq is often used to express the amount of electrolytes (such as potassium, sodium, calcium) in a solution or dosage form. It represents 1/1000th of an equivalent, which is the amount of a substance that can react with or replace one mole of hydrogen ions (H+) It is important for healthcare professionals to understand these units when dealing with medications and intravenous fluids, as incorrect administration can lead to serious health complications.
Choice D rationale:
Miniequivalents. This is not the correct answer. "Mini" is not a standard prefix used in the International System of Units (SI) The correct prefix for a thousandth of an equivalent is "milli," making milliequivalents the appropriate unit of measurement for substances like electrolytes.

Correct Answer is D
Explanation
Choice B rationale:
Call for additional staff to assist with the transfer. The nurse's priority in this situation is ensuring the safety of the client during the transfer from the chair to the bed. Calling for additional staff provides the necessary support to safely move the client, minimizing the risk of falls or injuries. It is crucial to have an adequate number of staff members to assist in transfers, especially when the client's mobility is compromised.
Choice A rationale:
Obtain a walker for the client to use to transfer back to bed. While a walker can be helpful for mobility, the client has already asked to return to bed, indicating the immediate need for assistance. Waiting to obtain a walker could delay the transfer, potentially putting the client at risk.
Choice C rationale:
Use a transfer belt and assist the client back into bed. Using a transfer belt is a suitable technique for assisting clients with mobility. However, the nurse's priority in this scenario is to ensure there is enough staff assistance to guarantee a safe transfer. The nurse should not attempt to perform the transfer alone, even with a transfer belt, as it might be unsafe for both the nurse and the client.
Choice D rationale:
Determine the client's ability to help with the transfer. While assessing the client's ability to participate in the transfer is important, it is not the nurse's priority in this situation. The immediate concern is to secure adequate assistance to safely move the client back to bed.
Correct Answer is D
Explanation
Choice A rationale:
Confine the fire by closing doors and windows. Rationale: While confining the fire is essential, the nurse's first priority should be the safety of the client. Closing doors and windows can wait. The nurse should focus on immediate actions to ensure the client's safety.
Choice B rationale:
Activate the fire alarm system. Rationale: Activating the fire alarm system is crucial to alert others in the healthcare facility about the fire. This action ensures a timely response from the fire department and other staff members, enhancing overall safety within the facility.
Choice C rationale:
Extinguish the fire if possible. Rationale: Attempting to extinguish the fire might lead to delay, especially if the nurse is not trained to handle fires properly. Moreover, the nurse's safety is paramount, and attempting to put out the fire could put the nurse at risk. Prioritizing the client's immediate rescue is the best course of action.
Choice D rationale:
Rescue the client from immediate danger. Rationale: The correct action for the nurse to take first is to rescue the client from immediate danger. This may involve helping the client out of the room or moving them away from the source of the fire. Ensuring the client's safety is the top priority, and all other actions should follow after this.
