Psychiatric Drugs MCQ

Explanation:

• a) Fluoxetine: Incorrect (generally). Fluoxetine is an SSRI that is more commonly associated with insomnia or activation, although drowsiness can occur in some individuals. (Source: HCP p.213 lists sedation/drowsiness as ‘Others’ but insomnia is also listed).
• b) Clomipramine: Correct. Clomipramine is a tricyclic antidepressant with significant sedative properties due to antihistaminic effects. (Source: SOTP 7th Ed, p.470; HCP p.214 lists ‘drowsiness’ for TCAs).
• c) Methylphenidate: Incorrect. Methylphenidate is a CNS stimulant used for ADHD and narcolepsy; it typically causes alertness and can cause insomnia.
• d. Imipramine: Correct. Imipramine is a tricyclic antidepressant known for its sedative side effects. (Source: SOTP 7th Ed, p.470; HCP p.214 lists ‘drowsiness’ for TCAs).
• e. Mirtazapine (Added option): Correct. Mirtazapine is an antidepressant well-known for causing significant drowsiness/sedation due to its potent H1 receptor antagonism. (Source: HCP p.215; SOTP 7th Ed, p.478).

Original question only had options up to D. Option E (Mirtazapine) added as per instruction to add options if missing to make it a 5-option question and provide explanation.

Explanation:

• a) Thought stopping in patient with specific phobia: True (conditionally). Thought stopping can be used as a technique to manage intrusive distressing thoughts, which might occur in specific phobias, though exposure therapy is the core treatment. It’s more commonly associated with OCD or GAD. (Source: SOTP 7th Ed, p.564 describes thought stopping for obsessional thoughts). So, plausible but not primary.
• b) Analyzing dream is a key component of cognitive treatment: False. Dream analysis is a key component of psychodynamic psychotherapy, not cognitive therapy. Cognitive therapy focuses on identifying and modifying dysfunctional thoughts, beliefs, and behaviours related to current problems. (Source: SOTP 7th Ed, p.566-569 on CBT).
• c) Group therapy is effective in management of acute symptoms of psychosis: False. During acute psychosis, individual management, medication, and a low-stimulus environment are prioritized. Group therapy can be beneficial once the acute phase has stabilized, for psychoeducation, social skills, and support. (Source: SOTP 7th Ed, p.278).

Considering option ‘a’ further: While exposure is primary for phobias, thought stopping *could* be an adjunctive technique for managing fear-related cognitions. Given the T/F, it’s borderline. Many would consider it false as it’s not a core or evidence-based *primary* treatment for specific phobia. Let’s mark ‘a’ as False due to it not being a primary/key intervention for specific phobia.

Explanation: Referencing HCP p.219 for Benzodiazepines.

• a) Inhibit GABA synaptic transmission: Incorrect. Benzodiazepines *enhance* GABAergic synaptic transmission by acting as positive allosteric modulators at GABA-A receptors, increasing the frequency of chloride channel opening. (Source: HCP p.219 “Action: Binds to benzodiazepine GABA-A receptors.”).
• b) Withdrawal symptoms may persist for > 3 months: Correct. Protracted benzodiazepine withdrawal syndrome can occur, with some symptoms persisting for months or even longer in some individuals after cessation. (Source: SOTP 7th Ed, p.523 “A few patients experience a protracted withdrawal syndrome…”).
• c) Contraindicated with MAOIs: Incorrect. There is no absolute contraindication to using benzodiazepines with MAOIs, though caution is always advised with polypharmacy. The primary concern with MAOIs is interactions with tyramine-containing foods or serotonergic/noradrenergic drugs.
• d. Are more effective than antidepressants in minor affective disorders: Incorrect. Antidepressants (e.g., SSRIs) and psychological therapies are generally preferred for minor affective (mood) disorders due to the risks of tolerance, dependence, and withdrawal associated with long-term benzodiazepine use. Benzodiazepines may offer rapid anxiolysis but are not a long-term solution for mood disorders.
• e. Metabolites are pharmacologically inactive: Incorrect. Many benzodiazepines (e.g., diazepam, chlordiazepoxide) have pharmacologically active metabolites (e.g., desmethyldiazepam, oxazepam) which contribute to their duration of action and accumulation. (Source: SOTP 7th Ed, p.521).

Explanation: HCP (p.204, p.206) outlines indications for antipsychotics including schizophrenia, acute mania, sedation of agitated patients, agitated depression, psychotic depression.

• a) Delusions in schizophrenia: Correct. Antipsychotics are the primary treatment for psychotic symptoms such as delusions and hallucinations in schizophrenia. (Source: HCP p.204, p.206 “Indications: Schizophrenia…”).
• b) Agitation in delirium: Correct. Low-dose antipsychotics (e.g., haloperidol) can be used short-term to manage severe agitation or psychotic symptoms in delirium, if non-pharmacological measures fail and the patient is distressed or a risk. (Source: NICE CG103 Delirium; HCP p.204 “sedation of agitated patients”).
• c) Rituals in OCD: Incorrect. SSRIs are the first-line pharmacological treatment for OCD. Antipsychotics may be used as an augmentation strategy in treatment-resistant OCD, but they don’t primarily reduce rituals on their own. (Source: NICE CG31 OCD and BDD).
• d) Psychomotor symptoms in dementia: Correct. Antipsychotics can be used cautiously and for limited duration to manage severe agitation, aggression or psychotic symptoms (Behavioural and Psychological Symptoms of Dementia – BPSD) if non-pharmacological measures are insufficient and there’s significant distress or risk. (Source: NICE NG97 Dementia: assessment, management and support). This relates to agitation.
• e) Cognitive decline in dementia: Incorrect. Antipsychotics do not improve or reduce cognitive decline in dementia; they may even worsen it and are associated with increased risks in this population. Cholinesterase inhibitors or memantine are used for cognitive symptoms. (Source: HCP p.220-221 for dementia cognitive enhancers).

Explanation: This question is a duplicate of Paper 6 (2010 Japura) Q11. Option ‘d’ here is ‘Needs to be connected to ventilation’ instead of ‘Apply local anaesthetic to the pads’.

• a) Done under GA: Correct. Modern ECT is always performed under general anesthesia. (Source: SOTP 7th Ed, p.546).
• b) Needs muscle relaxation: Correct. A muscle relaxant (e.g., succinylcholine) is administered to prevent musculoskeletal convulsions and potential injuries. (Source: SOTP 7th Ed, p.546).
• c) Needs intubation: Incorrect. Routine endotracheal intubation is not typically required. Ventilation is usually managed with a bag-valve-mask and oxygen.
• d) Needs to be connected to ventilation: Incorrect. This is similar to ‘intubation’. Routine connection to a mechanical ventilator is not standard. Oxygenation and airway are maintained, often via manual bag-mask ventilation during the brief apnea.
• e) Apply a local anaesthetic to the pads: Incorrect. Electrode sites are cleaned, and conductive gel is applied. Local anesthetic is not used on the pads.

Explanation: This question is duplicated as Paper 3 Q09. Answers are based on standard ECT procedure.

• a) Done under GA: Correct. Modern ECT is always performed under general anesthesia. (Source: SOTP 7th Ed, p.546).
• b) Needs muscle relaxation: Correct. A muscle relaxant (e.g., succinylcholine) is administered to prevent musculoskeletal convulsions and potential injuries. (Source: SOTP 7th Ed, p.546).
• c) Needs intubation: Incorrect. Routine endotracheal intubation is not typically required. Ventilation is usually managed with a bag-valve-mask and oxygen, unless specific anaesthetic or patient factors necessitate intubation. (Source: Royal College of Psychiatrists’ ECT handbook).
• d) Apply local anaesthetic to the pads: Incorrect. Electrode sites are cleaned, and conductive gel is applied to ensure good electrical contact. Local anesthetic is not applied to the electrode sites.
• e) Needs to be connected to a ventilator: Incorrect. As with intubation, routine connection to a mechanical ventilator is not standard. Oxygenation is maintained, often via manual ventilation during the brief period of apnea.

Explanation: This question asks about therapeutic factors *by the leader*. Yalom’s therapeutic factors are facilitated by the leader and emerge from the group process.

• a) Executive function performed by the leader: Correct. The group leader performs executive functions such as structuring the group, setting rules, managing time, and ensuring the group stays on task. This contributes to a safe and productive therapeutic environment. (Source: Yalom, I. D., & Leszcz, M. (2005). The theory and practice of group psychotherapy).
• b) Universality: Incorrect (as *by the leader*). Universality (realizing one is not alone) is a therapeutic factor experienced by group *members*. The leader helps *facilitate* its emergence by creating an environment where members can share openly, but it’s not directly ‘performed’ by the leader in the same way as executive functions.
• c) Scapegoating: Incorrect. Scapegoating is an anti-therapeutic or destructive group process that the leader should identify and manage or prevent.
• d) Regression: Incorrect. While regression can occur in groups and may be worked through, it’s not a therapeutic factor *performed by the leader*. The leader helps the group manage and understand regressive phenomena if they arise.
• e) Installation of hope: Correct. The leader plays a crucial role in instilling and maintaining hope within the group, both through their own optimistic demeanor and by highlighting members’ progress and the potential for change. (Source: Yalom, I. D., & Leszcz, M. (2005)).

The phrasing “by the leader” suggests actions the leader takes or roles they embody that directly contribute to the group’s therapeutic potential.

Explanation: EEG activation techniques are procedures used to increase the yield of an EEG by provoking or enhancing epileptiform abnormalities or other abnormal patterns.

• a) Breath holding: Incorrect. While breath-holding can cause physiological changes, it is not a standard EEG activation technique. Hyperventilation is.
• b) Neuroleptics: Incorrect. Neuroleptics (antipsychotics) can lower the seizure threshold and potentially induce EEG changes or seizures, but they are not used as a routine EEG activation technique due to risks and side effects. Some drugs (e.g. clozapine) are known to cause EEG changes or seizures.
• c) Sleep: Correct. Sleep, both natural and induced, is a common and effective EEG activation procedure, as certain epileptiform discharges are more likely to appear during drowsiness or sleep. (Source: Standard textbooks of Neurology/EEG, e.g., Fisch & Spehlmann’s EEG Primer).
• d) Photic stimulation: Correct. Intermittent photic stimulation (IPS) involves presenting flashing lights at various frequencies and is a standard technique to elicit photoparoxysmal responses or other abnormalities. (Source: Standard textbooks of Neurology/EEG).
• e) Sensory deprivation: Incorrect. While sensory deprivation can have profound psychological effects, it is not a standard EEG activation technique. Specific sensory stimuli (like photic or auditory) are used, not general deprivation.

Note: This question should be ‘checkbox’ as multiple options (Sleep, Photic Stimulation, Hyperventilation (not listed)) are standard. Given it is Q41 (implies radio from instruction but problem context did not provide type for this) and the example shows radio for >=40. Assuming this is radio, then only one can be best. Both sleep and photic are very standard. If only one choice is allowed and no best” option given usually EEG labs do hyperventilation and photic stimulation routinely. sleep is done if initial EEG is normal or specific epilepsy type is suspected. Photic stimulation is a very direct ‘activation’. Sleep is more a ‘state’ that activates. *Self-correction based on question format*: The source question has Q41, if forced to pick one, both are highly valid. Let’s assume the provided text implies these are distinct questions from a paper where numbering goes 1…N and >=40 is radio. Let’s pick one of the clearly correct ones. **Re-evaluation for Radio**: If it must be radio, ‘Photic stimulation’ is a very direct and universally applied ‘activation technique’. Sleep is also an activation but also a state. Photic stimulation is an active process done *to* the patient. This feels more like an “activation technique” in the active sense. Let’s pick D for radio. However, it’s a flawed question if it’s single-choice radio. **Instruction check**: “Determine correct answers”. If there are multiple correct answers for a radio, it’s problematic. For this I will interpret type as radio. *If the question format implies all options should be evaluated for truth for a radio, and pick the one true one, then there are two true options. This means the question source is flawed. I will pick the one that is an active stimulation technique.*

Final decision assuming Radio type from Q# and needing one correct answer, the prompt implies all options C and D are true for this specific context. As this is for a quiz plugin
