Which directional term means more toward the head or above another structure?

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.

Choice A rationale:

Using a fire extinguisher should not be the nurse's first action in this situation. The nurse's priority is to ensure the safety of the clients and staff in the vicinity. Attempting to use a fire extinguisher might not be effective and can potentially cause harm, especially if the fire spreads quickly.

Choice B rationale:

Activating the fire alarm is the nurse's priority in this situation. By activating the fire alarm, the nurse can alert everyone in the facility about the fire, ensuring that people are aware and can evacuate safely. This action initiates the facility's fire response protocol, leading to a quicker and organized response to the emergency.

Choice C rationale:

Moving clients to safety is important, but it is not the nurse's immediate priority in this situation. Activating the fire alarm should be done first to ensure that everyone in the facility is aware of the danger, and then the nurse can assist in moving clients to safety if necessary.
