C) Therapeutic effect
D) Anaphylactic reaction
D
Feedback:
The nurse should be aware that an anaphylactic reaction manifests as difficulty in breathing, syncopal episodes, rapid pulse, and palpitations. Anaphylactic reaction is a medical emergency that the nurse must recognize and treat promptly. Medication toxicity is an undesired, harmful effect that results from an increased blood level of the medication beyond its therapeutic level. If the client's response is opposite to that which is desired, it is referred to as a paradoxical effect. Therapeutic effect is the medication's desired effect and not its complications.
