Psychiatric Medications: A Nursing Student Study Guide
Psychopharmacology questions are less about pharmacology than about nursing: what you monitor, which adverse effect means stop-and-report, and what the patient must understand before discharge. This page organises the major psychiatric drug classes from that angle and links to the in-depth articles on lithium, clozapine and antipsychotic adverse effects.
Quick review
- Every psychiatric medication question tests one of three things: monitoring (what you check and how often), recognition (which finding is an emergency) or teaching (what the patient must do at home).
- Emergencies to recognise on sight: neuroleptic malignant syndrome, acute dystonia affecting the airway, lithium toxicity, serotonin syndrome, clozapine-related neutropenia or myocarditis, and respiratory depression with benzodiazepines plus other depressants.
- Most psychiatric medications take days to weeks to reach full effect; early weeks are when adverse effects appear and when adherence is most fragile.
- Never stop abruptly: antidepressants, benzodiazepines, mood stabilisers and antipsychotics all have discontinuation risks.
- The in-depth articles: lithium, clozapine, antipsychotic side effects (EPS vs NMS vs tardive dyskinesia).
How to approach medication questions
Read the stem for the drug class, the time since the drug was started or changed, and any new finding. Then ask three questions in order. Is the finding an emergency for this class (stop the drug, escalate)? If not, is it an expected adverse effect the nurse manages and reports (monitor, teach, document)? If neither, is the question really about teaching — a patient statement that shows understanding or a gap? Options that treat a symptom in isolation ("offer fluids", "reassess in an hour") when the stem describes an emergency are the classic distractors. The practice question set is built around this sequence.
Antipsychotics
Used for schizophrenia and other psychotic disorders, acute mania, and several other indications. First-generation ("typical") agents are more associated with movement adverse effects; second-generation ("atypical") agents with metabolic effects — though the categories overlap and any antipsychotic can cause neuroleptic malignant syndrome. The National Institute of Mental Health notes that long-term use of typical antipsychotics may lead to tardive dyskinesia, and that people taking atypical antipsychotics may be asked to take part in regular monitoring of weight, glucose and lipids.
| What the nurse monitors | Why | Patient teaching |
|---|---|---|
| Movement: acute dystonia, akathisia, parkinsonism, tardive dyskinesia | Dystonia can affect swallowing and breathing; akathisia drives non-adherence; tardive dyskinesia may be irreversible | Report muscle spasms, restlessness, new involuntary movements — do not stop the drug on your own |
| Temperature, rigidity, consciousness, autonomic signs | Neuroleptic malignant syndrome is a medical emergency | Seek urgent care for high fever with stiffness or confusion |
| Weight, waist, glucose, lipids | Metabolic effects raise long-term cardiovascular risk | Diet, activity, and keeping monitoring appointments |
| Orthostatic blood pressure, sedation, anticholinergic effects | Falls; constipation and urinary retention | Rise slowly; fluids and fibre; avoid alcohol and other sedatives |
| Clozapine only: absolute neutrophil count, cardiac symptoms, bowel function | Severe neutropenia, myocarditis and bowel hypomotility can be life-threatening | Blood tests are a condition of treatment; report fever, sore throat, chest pain, breathlessness or constipation the same day |

Mood stabilisers
Lithium and certain anticonvulsants (valproate, carbamazepine, lamotrigine) are used to treat and prevent the episodes of bipolar disorder; some second-generation antipsychotics are also used. The nursing themes are a narrow margin between effect and toxicity (lithium), organ-function monitoring, teratogenic risk with several agents, and teaching that keeps the level stable at home.
| Agent | What the nurse monitors | High-yield teaching |
|---|---|---|
| Lithium | Serum levels on schedule and whenever toxicity is suspected; renal and thyroid function; hydration and sodium status; GI symptoms, tremor quality, gait and alertness | Steady fluid and salt intake; report vomiting, diarrhoea, fever or a new medication; know the early toxicity signs; never double a missed dose |
| Valproate | Liver function, platelets, GI symptoms, weight; pregnancy status | Report bruising, bleeding, abdominal pain or jaundice; contraception planning |
| Carbamazepine | Blood counts, liver function, sodium; drug interactions | Report fever, sore throat, rash, unusual bleeding |
| Lamotrigine | Rash, especially early or after a dose change | Report any rash immediately; do not restart after a gap without the prescriber |

Antidepressants
SSRIs, SNRIs, atypical agents, tricyclics and MAOIs treat depressive and many anxiety disorders. The nursing themes are delayed benefit, early risk, and interactions.
| Concern | What the nurse monitors | Patient teaching |
|---|---|---|
| Suicide risk early in treatment | Mood, energy and suicidal thoughts in the first weeks and after dose changes — energy can return before mood lifts; NIMH notes that children, teenagers and young adults under 25 may experience increased suicidal thoughts or behaviour, especially in the first weeks | Benefit takes weeks; report worsening mood or new suicidal thoughts at once; keep follow-up appointments |
| Serotonin syndrome | Agitation, confusion, sweating, tremor, muscle twitching, fever, rapid heart rate — especially when serotonergic drugs are combined | Tell every prescriber and pharmacist; avoid combining with other serotonergic products including some supplements and pain relievers |
| Discontinuation symptoms | Dizziness, nausea, irritability, "electric" sensations after abrupt stopping | Do not stop suddenly; taper with the prescriber |
| MAOIs | Hypertensive crisis with tyramine-rich foods and many drugs | Dietary restrictions and a drug-interaction list; report severe headache, stiff neck, palpitations |
| Tricyclics | Anticholinergic and cardiac effects; lethal in overdose | Supply quantity is a safety issue in a patient at risk of suicide |
| Bipolar disorder | Antidepressants given alone can precipitate mania | Report reduced need for sleep, racing thoughts or unusual energy |

Anxiolytics and sedative-hypnotics
Benzodiazepines are used for acute anxiety, agitation, alcohol withdrawal and short-term sleep problems; non-benzodiazepine hypnotics for sleep; buspirone and antidepressants for longer-term anxiety. The nursing themes are sedation and falls, respiratory depression when combined with opioids, alcohol or other depressants, dependence, and a withdrawal syndrome that can include seizures if the drug is stopped abruptly after regular use. Teaching: no alcohol, no driving until the effect is known, do not stop suddenly, and do not share or stockpile. The class boxed warning and the nursing response to it are set out in Benzodiazepine Nursing Considerations; clinical context in anxiety nursing interventions.
Medications for substance use disorders
Naloxone reverses opioid overdose and can wear off before the opioid does, so the patient is observed for re-sedation; medications for opioid, alcohol and nicotine use disorders each have timing rules relative to last use (precipitated withdrawal is the exam theme) and rely on adherence support and non-judgemental follow-up.
Safety priorities across all classes
Priority nursing actions
- Know the emergency for each class and the first nursing action: hold the drug, stay with the patient, escalate.
- Verify monitoring is actually happening — levels, blood counts, metabolic labs — before the next dose or supply.
- Assess adherence barriers without blame: adverse effects, cost, insight, routine, supply.
- Teach in the patient's words and check understanding with teach-back.
- Document new findings precisely (onset, character, vital signs) so the prescriber can act.
Common exam trap
Choosing the option that manages a symptom when the stem describes an emergency. Fever plus rigidity on an antipsychotic is not "encourage fluids"; sore throat on clozapine is not "lozenges"; diarrhoea on lithium is not "an antidiarrhoeal". Name the emergency first, then act.
