A nurse is reviewing a medication order for a pediatric patient. The order states, "Administer 5 mg/kg of medication X orally." The child weighs 22 kg. How much medication should the nurse administer?
A. 95 mg
Calculation: Dosage = 5 mg/kg Weight = 22 kg Dose = Dosage × Weight = 5 × 22 = 110 mg
B. 100 mg
Calculation: Dosage = 5 mg/kg Weight = 22 kg Dose = Dosage × Weight = 5 × 22 = 110 mg
C. 110 mg
Calculation: Dosage = 5 mg/kg Weight = 22 kg Dose = Dosage × Weight = 5 × 22 = 110 mg
D. 120 mg
Calculation: Dosage = 5 mg/kg Weight = 22 kg Dose = Dosage × Weight = 5 × 22 = 110 mg

A patient is prescribed 500 mg of a medication. The available concentration is 250 mg/5 mL. How many milliliters should be administered?
A. 10 ml
Calculation: Ordered Dose = 500 mg Available Dose = 250 mg Available Volume = 5 mL Volume to administer = (Ordered Dose / Available Dose) × Available Volume = (500 / 250) × 5 = 2 × 5 = 10 mL
B. 20 ml
Calculation: Ordered Dose = 500 mg Available Dose = 250 mg Available Volume = 5 mL Volume to administer = (Ordered Dose / Available Dose) × Available Volume = (500 / 250) × 5 = 2 × 5 = 10 mL
C. 15 mL
Calculation: Ordered Dose = 500 mg Available Dose = 250 mg Available Volume = 5 mL Volume to administer = (Ordered Dose / Available Dose) × Available Volume = (500 / 250) × 5 = 2 × 5 = 10 mL
D. 5 mL
Calculation: Ordered Dose = 500 mg Available Dose = 250 mg Available Volume = 5 mL Volume to administer = (Ordered Dose / Available Dose) × Available Volume = (500 / 250) × 5 = 2 × 5 = 10 mL
Full Explanation
Calculation:
Ordered Dose = 500 mg
Available Dose = 250 mg
Available Volume = 5 mL
Volume to administer = (Ordered Dose / Available Dose) × Available Volume
= (500 / 250) × 5
= 2 × 5
= 10 mL
During medication administration, a nurse notices a discrepancy between the prescriber's order and the medication label. What should the nurse do first?
A. Ask a colleague for their opinion.
Ask a colleague for their opinion: Consulting a colleague can provide guidance, but the final clarification must come from the prescriber to ensure the order is accurate and legally authorized.
B. Contact the prescriber to clarify the order.
Contact the prescriber to clarify the order: The nurse’s first responsibility is to verify any discrepancies with the prescriber. Clarifying the order ensures patient safety, prevents medication errors, and maintains compliance with legal and professional standards.
C. Adjust the dosage according to the label.
Adjust the dosage according to the label: Changing the dose without prescriber approval is unsafe and could lead to underdosing or overdosing, placing the patient at risk for adverse effects.
D. Administer the medication as it is labeled.
Administer the medication as it is labeled: Administering the medication without resolving the discrepancy can result in serious medication errors and compromise patient safety.

Which of the following is a critical step in preventing medication errors during oral medication administration?
A. Using a pill cutter for all tablets.
Using a pill cutter for all tablets: A pill cutter should only be used when tablets are scored and intended to be split. Using it indiscriminately can alter the dose and lead to errors.
B. Administering the medication in a quiet environment.
Administering the medication in a quiet environment: While a calm environment reduces distractions, it is a supportive measure rather than a critical safety step in preventing errors.
C. Performing three label checks before administration
Performing three label checks before administration: Checking the medication label three times—when retrieving, preparing, and before giving the drug—ensures the correct patient, drug, dose, route, and time. This practice is a key strategy to prevent medication errors and enhance patient safety.
D. Ensuring the medication is taken with food or milk
Ensuring the medication is taken with food or milk: Administering with food or milk may improve tolerance or absorption for certain medications, but it does not universally prevent medication errors. The critical step is accurate identification and verification of the medication.
