How does using two patient identifiers promote safe medication administration?
Ensures the right client is receiving the medication
Verifies the medication dosage
Confirms the right route of administration
Determines the right time for administration
The Correct Answer is A
A. Ensures the right client is receiving the medication: Using two patient identifiers, such as name and date of birth or medical record number, confirms that the medication is administered to the correct individual. This practice helps prevent medication errors caused by misidentification, which is a common source of adverse events in clinical settings.
B. Verifies the medication dosage: While verifying the correct dose is crucial, two patient identifiers do not directly ensure dosage accuracy. Dosage verification relies on comparing the prescription with the medication label and calculation.
C. Confirms the right route of administration: Ensuring the correct route is important for therapeutic effect, but this is verified by checking the order and preparation instructions, not by patient identifiers.
D. Determines the right time for administration: Timing is critical for medication effectiveness, but two patient identifiers are unrelated to scheduling or timing; they focus specifically on client verification to prevent misadministration.

Correct Answer is B
Explanation
A. Verifying the medication order with the pharmacy: This action supports the right medication and safe administration, but it does not constitute documentation of administration.
B. Recording the time and dose immediately after administration: Documenting the exact dose, route, and time immediately after giving the medication ensures an accurate record, supports continuity of care, and prevents errors such as double dosing.
C. Observing the patient for adverse reactions: Monitoring for reactions is essential for patient safety, but it reflects assessment rather than documentation of administration.
D. Checking the patient's identity before administration: Verifying the patient’s identity aligns with the right patient, a safety measure, but it is not documentation of the administered medication.
Correct Answer is C
Explanation
A. Centi-: The prefix centi- represents 1/100 of the base unit. It is commonly used for measurements like centimeters, which are 1/100 of a meter, so it does not correspond to 1/1,000th.
B. Deci-: Deci- represents 1/10 of the base unit. For example, a deciliter is 1/10 of a liter. This is larger than 1/1,000th and is not the correct prefix.
C. Milli-: Milli- corresponds to 1/1,000 of the base unit. For instance, 1 milligram is 1/1,000 of a gram, and 1 milliliter is 1/1,000 of a liter, making it the correct prefix for this fraction.
D. Micro-: Micro- represents 1/1,000,000 (one-millionth) of the base unit, which is much smaller than 1/1,000th.
