Question 1 of 5
A hospitalized patient who has been taking an antipsychotic medication for 2 weeks begins pacing and walking throughout the unit. He tells the nurse that he cannot sit still. The nurse documents this finding as which of the following?
Correct Answer: D
Rationale: Akathisia is characterized by restlessness and an inability to sit still, common with antipsychotics. Akinesia involves reduced movement, dystonia causes muscle spasms, and pseudoparkinsonism mimics Parkinson?s symptoms like tremor, not restlessness.
Question 2 of 5
The nurse observes an older adult patient who has been taking antipsychotic medications for 8 months. The patient is smacking her lips and blinking her eyes rapidly. The nurse also observes a protruding tongue. Which action by the nurse would be most appropriate?
Correct Answer: C
Rationale: Lip smacking, rapid blinking, and tongue protrusion indicate tardive dyskinesia, a serious side effect of long-term antipsychotic use. Documenting these symptoms is the most appropriate initial action to ensure accurate reporting and prompt physician review. Asking about side effects is vague, contacting the physician follows documentation, and tapering is premature without medical orders.
Question 3 of 5
A nurse is working as part of a team involved with the testing of a new psychiatric medication. The drug is currently being used in multiple clinical trials at various different sites. The nurse is engaged in which phase of testing?
Correct Answer: C
Rationale: Phase III clinical trials involve testing a drug in multiple sites with larger populations to confirm efficacy and safety, matching the scenario. Phase I tests safety in small groups, Phase II assesses efficacy in a limited population, and Phase IV occurs post-market.
Question 4 of 5
A nursing instructor is teaching a class on the pharmacodynamics of psychiatric medications. The instructor determines that additional teaching is needed when the students identify which of the following as a site of action?
Correct Answer: C
Rationale: Pharmacodynamics involves how drugs act on the body, typically at receptors, ion channels, or enzymes. Neurotransmitters are chemicals that transmit signals, not sites of drug action, indicating a need for further teaching.
Question 5 of 5
A nurse is reviewing information about a psychiatric medication that describes the amount of the drug that actually reaches systemic circulation unchanged. The nurse identifies this as which of the following?
Correct Answer: B
Rationale: Bioavailability is the proportion of a drug that reaches systemic circulation unchanged. The first-pass effect reduces bioavailability, solubility affects dissolution, and biotransformation is metabolism, not systemic delivery.
