A nurse is preparing to administer atropine 0.02 mg/kg via IV bolus to a school-age child who weighs 30 kg. Available is 0.4 mg/mL. How many mL should the nurse administer? (Round your answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero).
The Correct Answer is ["1.5"]
Calculation:
- Calculate the total dose in milligrams (mg).
Ordered dose: 0.02 mg/kg
Patient weight: 30 kg
Total dose (mg) = 0.02 mg/kg x 30 kg
= 0.6 mg.
- Calculate the volume to administer in milliliters (mL).
Total dose: 0.6 mg
Available concentration: 0.4 mg/mL
Volume (mL) = Total Dose (mg) / Available Concentration (mg/mL)
= 0.6 mg / 0.4 mg/mL
= 1.5 mL.

Correct Answer is B
Explanation
A. Inform the nursing manager: While notifying the manager is important for accountability and support, it does not address the immediate safety needs of the client.
B. Monitor the client's condition: The first action after a medication error is to assess and monitor the client for any adverse effects. Ensuring the client’s safety and identifying early signs of complications takes priority over reporting.
C. Notify the client's provider: The provider should be informed promptly, but only after assessing the client and determining their current condition and any immediate interventions needed.
D. Complete an occurrence report: Documenting the error is essential for legal and quality improvement purposes, but it is not the first priority. The client’s safety must be addressed before reporting the incident.
Correct Answer is A
Explanation
A. Examine the client's upper body for flushing of the skin during the infusion: Red man syndrome is a common adverse effect of rapid IV vancomycin administration. It presents as flushing or rash on the upper body, and monitoring for this reaction is essential to ensure client safety.
B. Monitor for hypertension while the medication infuses: Vancomycin is more commonly associated with hypotension rather than hypertension during infusion, so monitoring for high blood pressure is not a primary concern.
C. Check for a penicillin cross-sensitivity before infusing the medication: Vancomycin is not a beta-lactam antibiotic, so penicillin allergy does not predict vancomycin reactions. Screening for cross-sensitivity is not required.
D. Infuse the medication over 30 min: Rapid infusion increases the risk of adverse effects such as red man syndrome. Vancomycin should typically be infused over at least 60 minutes or longer, depending on the dose, to reduce this risk.
