An agitated psychiatric client is given a sedating medication to produce a calming effect, but instead the client becomes more anxious and agitated. What type of reaction did the client have to this medication?
Paradoxical effect
Anaphylaxis
Potentiation
Medication toxicity
The Correct Answer is A
A. Paradoxical effect: A paradoxical effect occurs when a drug produces the opposite of its intended response, such as increased agitation after a sedative, which is typical in certain psychiatric or elderly patients.
B. Anaphylaxis: Anaphylaxis is a severe, life-threatening allergic reaction characterized by airway swelling, hypotension, and rash, not behavioral changes.
C. Potentiation: Potentiation refers to one drug enhancing the effect of another, not an opposite or unexpected response to a single drug.
D. Medication toxicity: Toxicity involves harmful accumulation or overdose symptoms, usually physical rather than behavioral agitation.

Correct Answer is D
Explanation
A. Defer the calculation process to the physician.: It is the nurse’s professional responsibility to calculate and verify medication dosages before administration. Deferring this task to the physician compromises accountability.
B. Call the pharmacy to provide the appropriate calculations.: While pharmacists can assist with complex dosing, the nurse should independently perform and verify dosage calculations. Relying solely on the pharmacy removes a critical safety check within the medication administration process.
C. Consult a current drug book to confirm the new dosage.: Referring to a drug reference is an excellent step for verifying safe dosage ranges and medication information but does not replace the need for independent dose calculation verification.
D. Have another licensed nurse confirm the calculation.: The best way to minimize error is to double-check the dosage with another licensed nurse. Independent verification ensures accuracy, particularly for high-risk medications such as insulin, heparin, and opioids, enhancing overall medication safety.
Correct Answer is C
Explanation
A. 60.: Sixty minutes equals one hour, not two. This underestimates the total time by half and would be incorrect in any time-based calculation or scheduling scenario.
B. 600.: Six hundred minutes would equal ten hours, which significantly overestimates the duration. This conversion error could lead to major timing mistakes in medication administration or monitoring.
C. 120.: One hour equals 60 minutes; therefore, two hours equal 60 × 2 = 120 minutes. This is the correct and precise conversion used for accurate time-related calculations in nursing and clinical practice.
D. 6.: Six minutes is far less than one hour and does not represent a realistic conversion. This would indicate a miscalculation of time by a large margin.
