The patient has a medication bottle that says "Each tablet contains 750 mcg of medication." The pharmacist provides a refill of the same medication with the information "Each tablet contains 0.75 mg of medication." The nurse is correct to inform the patient that:
The tablets in the new refill contain the same amount of medication.
The tablets in the refill bottle contain less medication.
The tablets in the refill bottle have a greater dose of medication.
The pharmacy needs to provide tablets that contain 750 mcg of medication.
The Correct Answer is A
A. The tablets in the new refill contain the same amount of medication: 0.75 mg is equivalent to 750 mcg (1 mg = 1000 mcg), so the dose strength has not changed. The patient is receiving the same amount of active drug.
B. The tablets in the refill bottle contain less medication: Converting 0.75 mg to micrograms shows it equals 750 mcg, so the refill does not contain less medication.
C. The tablets in the refill bottle have a greater dose of medication: The dose is identical, not greater. There is no change in the amount of active ingredient per tablet.
D. The pharmacy needs to provide tablets that contain 750 mcg of medication: Although the labeling changed, 0.75 mg is equivalent to 750 mcg. The refill is correct and safe to use.

Correct Answer is C
Explanation
A. in: The abbreviation “in” is commonly used to indicate inches and is widely recognized in clinical and household contexts. It does not pose a risk of misinterpretation in medication administration.
B. tsp: “tsp” stands for teaspoon and is a standard, accepted abbreviation for liquid measurements. It is safe for use when teaching patients or administering medications.
C. OZS: The correct abbreviation for ounces is “oz,” not “OZS.” Using “OZS” can lead to misinterpretation and dosing errors, making this abbreviation unsafe and in need of clarification.
D. tbsp: “tbsp” stands for tablespoon and is an accepted and widely understood abbreviation. It is standard for measuring liquid medications and does not require questioning.
Correct Answer is D
Explanation
A. The units of measurement on drug labels help to identify the strength of the drug: Units on labels indicate the precise amount or potency of a medication, which guides safe and accurate dosing for therapeutic effect.
B. The unit of measurement labeled "unit" expresses the biological activity of the drug: Some medications, such as insulin and heparin, are measured in units to reflect their biological activity rather than weight or volume, which is accurate.
C. The mL, L, and meter are units of measurement found in the metric system: Milliliters, liters, and meters are standard metric units for volume and length, commonly used in medication administration and clinical measurements.
D. The mEq unit of measurement has the same concentration of solution as the mcg: Milliequivalents (mEq) measure chemical activity or ion concentration, whereas micrograms (mcg) measure mass. These units are not equivalent, so this statement requires clarification.
