Chapter 22: Preparation for Safe Medication Administration Perry et al.: Nursing Interventions & Clinical Skills, 7th Edition MULTIPLE CHOICE 1. A patient received a drug that caused an unpredictable and unusual effect. Which term does
the nurse use to describe this effect? a. Toxic b. Allergic c. Therapeutic d. Idiosyncratic ANS: D
An unpredictable overreaction or underreaction to a medication is an idiosyncratic reaction. Toxic medication effects occur with prolonged therapy, excessive dosing, or impaired metabolism or systemic accumulation in the patient. They are adverse effects with the potential to cause patient injury and death. Allergic reactions are unpredictable, unless the patient has a history of a medication allergy and result from an immunological patient response to the medication involving antibody formation. A therapeutic response is a desirable or intended patient response. DIF: Cognitive Level: Remembering TOP: Nursing Process: Assessment
OBJ: NCLEX: Physiological Integrity
2. The nurse administers a combination medication for a desirable patient response derived from
the combination of agents. Which type of medication effect does the nurse anticipate? N a. Tolerance b. Synergistic c. Dependence d. Subtherapeutic ANS: B
The nurse anticipates a synergistic effect because the two different medications work better in combination than either agent works alone. Drug tolerance means that a larger dose of medication is needed to produce the same therapeutic effect over time. Drug dependence is psychological or physical. The patient takes the medication for an effect other than the therapeutic effect, resulting in psychological dependence. Physical dependence involves physiological adaptation to the medication that results in severe adverse effects if withdrawn abruptly. A subtherapeutic effect is less than therapeutic; the therapy treats the disorder inadequately. DIF: Cognitive Level: Remembering TOP: Nursing Process: Assessment
