The order is for the patient to take 100 mg PO daily. The nurse reads the following label and correctly informs the patient:
Azithromycin
for Oral Suspension, USP
100 mg per 5 mL
300 mg (15 mL when mixed)
FOR ORAL USE ONLY
MIXING DIRECTIONS:
Shake to loosen powder. Add 9 mL of water to the bottle.
After mixing, use within 10 days.
SHAKE WELL BEFORE USING.
Discard after full dosing is completed.
That every tablespoon has 300 mg of the drug
That every teaspoon has 300 mg of the drug
That they should use a measuring device that accurately measures mL
That they should mix the ordered dose with an 8-oz glass of water
The Correct Answer is C
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.

Correct Answer is D
Explanation
A. 0.054 mg is more than 0.06 mg: Numerically, 0.054 is less than 0.06, so this statement is incorrect. Administering 0.054 mg would result in a slightly lower dose than 0.06 mg.
B. The new dose is calculated to the thousandths place so it is 10 times greater: Changing the decimal place does not increase the dose tenfold. In fact, 0.054 mg is slightly smaller than 0.06 mg.
C. The new dose is about the same as the previous dose of 0.06 mg: While 0.054 mg is close to 0.06 mg, it is technically a lower dose. Stating it is “about the same” could be misleading in clinical contexts where precise dosing matters.
D. 0.054 mg is less than 0.06 mg: Comparing the numeric values shows that 0.054 mg is slightly smaller than 0.06 mg. This statement accurately informs the patient of the dose reduction.
Correct Answer is B
Explanation
A. Ask the patient if they want to take the medication: While obtaining the patient’s cooperation is important, it does not ensure that the right patient receives the correct medication. Patient preference cannot substitute for proper identification and safety checks.
B. Identify the patient using two identifiers: Correct patient identification using two unique identifiers, such as name and date of birth, is the most critical safety step before administering any medication. It prevents medication errors and ensures that the drug reaches the intended recipient.
C. Tell the patient the medication is safe: Providing reassurance is important for patient comfort, but it does not guarantee safety. Safety is ensured through verification of the medication, dose, and patient identity before administration.
D. Verify the medication with another nurse: Double-checking is essential for high-risk medications, but for routine oral medications, the initial priority is accurate patient identification. Verification with another nurse is secondary to confirming the correct patient.
