When determining weight-based medication dosages, the nurse should use the patient's
The Correct Answer is {"dropdown-group-1":"C"}
A. Birth: Birth weight is only relevant for neonates and infants when calculating neonatal or pediatric dosages. It is not appropriate for current dosing in older children or adults.
B. Stated: A patient’s stated weight may be inaccurate due to misestimation or recall errors. Relying solely on what the patient reports can lead to incorrect dosing.
C. Current: The patient’s current, measured weight is used to calculate weight-based medication dosages. Accurate, up-to-date measurements ensure safe and effective dosing, especially for medications with narrow therapeutic windows.
D. Estimated: Estimating a patient’s weight is only used in emergency situations when actual measurement is impossible. Whenever feasible, the actual current weight should be used for precise dosing calculations.

Correct Answer is D
Explanation
A. In the medication storage room while selecting the medication: Verifying the medication in the storage area is an important initial check, but it does not confirm the correct client or final safety considerations. Errors can still occur if the final check is not performed at the bedside.
B. At the time of documentation after administering the medication: Documentation after administration records the event but does not prevent errors during administration. Verification at this point is too late to ensure safety.
C. At the nurse's station while reviewing the provider's prescription: Reviewing orders at the nurse’s station helps with preparation, but it does not verify the correct medication, dose, or route for the specific client at the time of administration.
D. At the client's bedside immediately before giving the medication: The final verification at the bedside ensures the “five rights” of medication administration—right client, right drug, right dose, right route, and right time—are confirmed immediately prior to administration. This is the safest practice to prevent errors.
Correct Answer is C
Explanation
Calculation:
- Identify the ordered dose and available concentration
Ordered Dose: 2 mg
Available Concentration: 4 mg/2 mL
- Calculate the volume to administer
Volume to administer = (Ordered Dose ÷ Available Dose) × Volume of Concentration
Volume to administer = (2 ÷ 4) × 2
Volume to administer = 0.5 × 2
= 1 mL
