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 D rationale:
When preparing to open a sterile pack, the nurse must touch only the inner surface of the inner wrapper to maintain sterility. This is a fundamental principle of aseptic technique. Sterile items should be handled with care to prevent contamination. By touching only the inner surface of the inner wrapper, the nurse ensures that the contents of the pack remain sterile and safe for use in medical procedures. Any contact with the outer surface or other non-sterile items can compromise the sterility of the contents.
Choice A rationale:
Placing the sterile pack on a clean surface is a good practice but does not ensure the maintenance of sterility. Sterile items should be placed on a sterile surface or field to prevent contamination. Placing the pack on a clean surface may still expose it to potential contaminants, compromising its sterility.
Choice B rationale:
Turning the pack so that the first flap faces the nurse's body is incorrect. The first flap should be opened away from the nurse to avoid the risk of contamination. By opening the flap away from the nurse, any potential contaminants in the air are less likely to come into contact with the sterile contents.
Choice C rationale:
Opening the right-side flap first is not a standard practice for opening a sterile pack. The choice of which side to open first may vary based on individual preference or the design of the packaging. The key factor is to maintain the sterility of the contents by handling the pack appropriately, as mentioned in choice D.
