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
The correct answer is D. Determine the client's ability to help with the transfer.
Choice A rationale:
While obtaining a walker might be helpful, it's not the first step. The nurse needs to assess the client's ability to assist with the transfer before deciding on the most appropriate aid.
Choice B rationale:
Calling for additional staff may be necessary, but this should come after assessing the client's ability to help with the transfer.
Choice C rationale:
Using a transfer belt is a good practice for safe transfers, but again, the nurse must first determine if the client can assist. This ensures the appropriate use of resources and techniques.
Choice D rationale:
Assessing the client's ability to help with the transfer is the first step. This assessment will guide the nurse in choosing the safest and most appropriate method for transferring the client, considering their capabilities and safety.
Correct Answer is B
Explanation
Choice A rationale:
Gastro- refers to the stomach. This prefix is commonly used in medical terminology to indicate conditions related to the stomach or the gastrointestinal system.
Choice B rationale:
Nephro- is the correct medical term for kidney. The prefix nephro- is used to indicate conditions related to the kidney, such as nephritis (inflammation of the kidney)
Choice C rationale:
Oto- refers to the ear. This prefix is commonly used in medical terms related to the ear and hearing, such as otitis (inflammation of the ear)
Choice D rationale:
Uro- refers to the urinary tract. While it is related to the kidneys in the context of the urinary system, it is not the specific term for kidney. Uro- is used in words like urology (the branch of medicine that deals with the urinary system and male reproductive system)
