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 C
Explanation
A. That every tablespoon has 300 mg of the drug: One tablespoon is 15 mL, which in this preparation contains 300 mg only after reconstitution. However, instructing the patient this way could lead to dosing errors, especially if they use household utensils instead of an accurate measuring device.
B. That every teaspoon has 300 mg of the drug: One teaspoon equals 5 mL, which contains 100 mg after reconstitution. Telling the patient that a teaspoon has 300 mg would result in a threefold overdose, making this statement unsafe.
C. That they should use a measuring device that accurately measures mL: Using an oral syringe or dosing cup ensures precise measurement of the prescribed 100 mg (5 mL) dose. This method minimizes errors and promotes safe administration, particularly for pediatric or adult liquid medications.
D. That they should mix the ordered dose with an 8-oz glass of water: The preparation instructions specify adding 9 mL of water to reconstitute the medication, not mixing the dose in a glass of water. Following this incorrect instruction could result in improper concentration and dosing errors.
