Question

A nurse reviews a medication order and finds that it is incomplete, lacking dosage information. What should the nurse do next?

Answer 1

Correct Answers:

Contact the prescriber to obtain the missing dosage information before administering the medication.

Rationale :

💊A medication order must be complete (client, drug, dose, route, time, and frequency) before the nurse can safely administer it.

⚖️Giving a drug without a specified dose violates legal and professional standards for medication administration.

🧠By contacting the prescriber for clarification, the nurse ensures accurate prescribing and avoids making unauthorized clinical decisions about dose.

🛡️This action prioritizes client safety, reduces the risk of medication errors, and maintains proper interprofessional communication.

📌Core Message

Ensuring complete and clarified orders from the prescriber before giving a medication protects client safety and legal accountability.

Answer 2

Correct Answers:

1

Rationale :

📏The ordered dose is 12.5 mg, and the available concentration is 12.5 mg in 5 mL, so the entire 5 mL contains the required dose.

🧪Using the formula (desired dose ÷ available dose) × volume, we get (12.5 ÷ 12.5) × 5 mL = 5 mL.

🥄Because 1 teaspoon equals 5 mL, 5 mL corresponds exactly to 1 teaspoon.

🛡️Accurate dose and unit conversion prevents underdosing or overdosing and helps maintain safe pediatric medication administration.

📌Core Message

Using the dose formula and knowing 5 mL = 1 tsp allows the nurse to safely convert milliliters to teaspoons for liquid medications.

Answer 3

Correct Answers:

Dosing should be based on the child's weight, and medications like acetaminophen can be given as needed.

Rationale :

🧸Pediatric dosing is calculated using the child’s weight in kilograms, because infants have different pharmacokinetics than adults.

💊For a 6-month-old with fever after immunization, acetaminophen is an appropriate antipyretic when given in a weight-based dose.

⚖️Using weight-based dosing helps avoid both underdosing (ineffective treatment) and overdosing (risk of toxicity).

🧠Teaching parents about weight-based medication dosing improves safe home administration and reduces harmful medication practices.

📌Core Message

Safe infant fever management relies on weight-based dosing of appropriate drugs like acetaminophen, reflecting infants’ unique drug handling compared with adults.

Answer 4

Correct Answers:

4.1

Rationale :

⚖️First convert the client’s weight: 29 lb ÷ 2.2 ≈ 13.2 kg, which is needed for mg/kg/day calculations.

📏The daily dose is 50 mg/kg/day, so 50 × 13.2 ≈ 660 mg per day of erythromycin.

⏱️The medication is given every 6 hours, which is 4 doses per day, so 660 mg ÷ 4 ≈ 165 mg per dose.

🧪The suspension is 200 mg in 5 mL (40 mg/mL), so 165 mg ÷ 40 mg/mL ≈ 4.1 mL per dose, rounded to the nearest tenth.

📌Core Message

For mg/kg/day problems, convert lb to kg, calculate the total daily dose, divide by the number of doses, then use the concentration to find mL per dose.

Answer 5

Correct Answers:

Yes, because the total daily dose is 900 mg, which is within the safe range of 700 mg to 1400 mg.

Rationale :

⚖️First convert the child’s weight: 77 lb ÷ 2.2 = 35 kg, needed to calculate the mg/kg/day range.

📏The prescription is 300 mg every 8 hours, which totals 300 × 3 = 900 mg per day.

🧮The safe range is 20–40 mg/kg/day, so 20 × 35 = 700 mg and 40 × 35 = 1400 mg, giving a safe range of 700–1400 mg/day.

🛡️Because 900 mg/day lies between 700 and 1400 mg/day, the ibuprofen order is within the safe daily range for this child.

📌Core Message

By converting weight to kilograms, calculating the total daily dose, and comparing it with the 20–40 mg/kg/day range, the nurse verifies that 900 mg/day is safe.

Answer 6

Correct Answers:

1 tsp

Rationale :

🥄The prescription is for 5 mL of amoxicillin, which must be taught in teaspoons for client understanding.

📏The standard conversion is 5 mL = 1 teaspoon, a critical medication measurement fact.

🧠Explaining doses using teaspoons helps clients understand how much medication to measure at home, though a measuring device is preferred.

🛡️Correct mL-to-teaspoon conversion prevents accidental overdose or underdose when clients administer liquid medications.

📌Core Message

Knowing 5 mL = 1 tsp allows the nurse to translate prescribed milliliter doses into clear teaspoon instructions for clients.

Answer 7

Correct Answers:

Double-check the medication dosage with another nurse before administration.

Rationale :

⚠️High-alert medications have a greater risk of causing serious harm if errors occur, so they require extra safety precautions.

👥An independent double-check by two nurses helps identify errors in dose, drug, or route before the medication reaches the client.

📋This practice is part of standardized high-alert safety protocols for drugs such as insulin, heparin, and certain IV medications.

🛡️Using a second nurse verification significantly reduces the likelihood of adverse drug events and enhances client safety.

📌Core Message

High-alert medications require independent double-checks by another nurse to reduce medication errors and protect client safety.

Answer 8

Correct Answers:

1.5

Rationale :

🧮To find how many capsules are needed, divide the ordered dose (450 mg) by the available strength (300 mg per capsule).

📏450 mg ÷ 300 mg per capsule = 1.5 capsules, the exact number of units required.

📊Rounding to the nearest tenth, as instructed, keeps the answer at 1.5, since it already has one decimal place.

🧠This uses the standard solid-dose formula: dose required ÷ dose on hand = number of units to give.

📌Core Message

Using required dose ÷ available strength yields 1.5 capsules, demonstrating the standard approach for calculating solid oral medication units.

Answer 9

Correct Answers:

15 mL

Rationale :

📏The order is for 0.5 oz of apple juice, which needs conversion to milliliters for accurate measurement.

🧪The standard conversion is 1 oz = 30 mL, so 0.5 × 30 mL = 15 mL.

🥤Giving 15 mL ensures the exact ordered volume is used to mix or administer the medication.

🛡️Correct ounce-to-milliliter conversion is crucial to avoid dose and volume errors in medication administration.

📌Core Message

Applying 1 oz = 30 mL shows that 0.5 oz is 15 mL, ensuring accurate liquid volume measurement for medication administration.

Answer 10

Correct Answers:

16 fluid ounces

Rationale :

📏In the apothecary system, 1 pint is equal to 16 fluid ounces, a key volume relationship.

📚Understanding pint-to-ounce conversions helps when medication quantities are labeled in different measurement systems.

🧠Teaching caregivers that a pint equals 16 ounces improves their ability to interpret labels and instructions accurately.

🛡️Correct unit conversion supports safe preparation and dosing of liquid medications, especially in pediatric care.

📌Core Message

Recognizing that 1 pint = 16 fluid ounces allows accurate apothecary-to-household conversions and supports safe liquid medication dosing.
