Correct Answer is B
Explanation
A. Administer antihistamines immediately: While antihistamines can help manage mild allergic reactions, they are not sufficient for severe or life-threatening anaphylaxis. Immediate discontinuation of the offending medication and emergency interventions are the priority.
B. Discontinue the medication immediately: Stopping the causative medication is the first and most critical action to prevent further exposure and worsening of the anaphylactic reaction. This action is essential to patient safety and must be done before other interventions.
C. Notify the health care provider after completing the medication administration: Waiting to notify the provider after completing administration would delay emergency treatment and put the patient at serious risk of harm.
D. Document the reaction in the patient's medical record: Documentation is important for ongoing care and future medication safety, but it is not the immediate priority during an active anaphylactic reaction.
Correct Answer is A
Explanation
Ordered Dose: 25 mg
Available Concentration: 50 mg/5 mL
- Calculate the volume to administer
Volume to administer = (Ordered Dose ÷ Concentration) × Volume of Concentration
Volume to administer = (25 ÷ 50) × 5
Volume to administer = 0.5 × 5
Volume to administer = 2.5 mL
