Psychiatry form 3 answers
All info is from upto date site; most
authentic .
1.right answer is A .its a bipolar disorder type 1
In this case psychotic is must to fulfill the criteria .
Why not most close option of major depression because it has only 3
feature of MDD so despite having psychosis it cant be right answer
because it need 5 feature to label MDD.for other options duration is
not fulfilled as it has began 6 weeks ago.
2.right is d Adults with DS usually develop neuropathologic and functional changes typical of
Alzheimer disease by the sixth decade of life [8,18,19]. In one report, dementia was present in 49 of 96
(51 percent) DS individuals over the age of 35 years [18]. The average age of onset was 54 years, and
seizures developed in 84 percent of patients. .nucleaus of mynert is acetylcholine storage area so it wl be
deficient in Alzahemer disease
A=kluver buccy syndrome
B=huntigton
C=auditory problem
E=A lesion of the red nucleus causes resting tremor, abnormal muscle tone and choreoathetosis.
F=Parkinson
G=hemiblismus
3.answer is B Symptoms of Huntigton Disease begin insidiously with movement
abnormalities and/or with psychiatric and cognitive features. Chorea is a key feature of HD, and the
defining sign at the time of diagnosis. Psychiatric problems can include irritability, depression, dysphoria,
agitation, apathy, anxiety, paranoia, delusions, and hallucinations. The dementia of HD is characterized
by executive dysfunction.
Rest explained above
4. answer is C …desimpramine is TCA drug
A typical history should include questions about known heart disease (including congenital or acquired
long QT syndrome), syncope, palpitations, dyspnea on exertion, shortness of breath, or chest pain [19]. In
addition, clinicians should ask about a family history of heart disease, particularly sudden death, cardiac
dysrhythmias, or cardiac conduction disturbances.
Baseline screening laboratory tests should include serum potassium to rule out hypokalemia [19]. We
also recommend that patients over age 40 years have a baseline ECG for this purpose. Patients younger
than 40 years can be screened by history for cardiac disease and do not require an ECG if the history is
negative.
In cases where QT is prolonged it is sign of drug overdose or silent heridetry QT prolongation defect
which appeared now .so do ECG plus K level imp.
Switch to pimoline after discontinuation of TCA drug as first best step ..pemoline is stimulant LIKE
methamphetamine used for ADHD
5 right answer is E
Clinicians should consider the diagnosis of methamphetamine intoxication in any diaphoretic patient
with hypertension, tachycardia, severe agitation, and psychosis. Patients with methamphetamine
intoxication range from the virtually asymptomatic to those in sympathomimetic crisis with imminent
cardiovascular collapse.
●Methamphetamine can cause a host of respiratory, cardiac, vascular, otolaryngologic, neurologic,
integumentary, psychiatric, infectious, traumatic, and dental maladies. Agitation, tachycardia,
hypertension, and psychosis are among the most frequent findings. (
Ecstasy MDMA intoxication can cause a myriad of dangerous effects including severe hypertension,
hyperthermia, delirium, psychomotor agitation, and profound hyponatremia. Potential life-threatening
complications of these effects include intracranial hemorrhage, myocardial infarction, aortic dissection,
disseminated intravascular coagulation, rhabdomyolysis, seizure, and serotonin syndrome
Although there are specific serum and urine assays for MDMA, we advise against the use of these
assays to guide clinical management. A positive MDMA screening test cannot confirm that a patient's
symptoms are the result of MDMA toxicity. A negative test can occur despite the presence of MDMA
congeners, of which there are over 100. Such congeners may cause clinical symptoms that are
indistinguishable from MDMA toxicity. Regardless of whether the inciting agent is MDMA or a related
drug, management is identical and based solely on the patient's clinical status.
So in short we screen amphetamine by urine but not ectasy drug only difffernce except hyopnatrimia I
found after much searching
Other option dnt cause so much agitation
6.right is C
Always rule out suicidal ideation in a patient on pain medication or severly debillated patient
After that next option should be medication evaluation
7.ans is D
Pcp specific sign is nystgmus
Alcohl ontoxication is not so much stimulatory and without nystgmus
Other option are easy to rule out
8 right answer is A
Visual hallucination is initial sign of delirium .alll antidepressant are cayuse of delirium so fist step is to
stop them in elderly .its due to antimuscrinic effects .Acetylcholine plays a key role in the pathogenesis of
delirium [13,14]. Anticholinergic drugs cause delirium when given to healthy volunteers and are even
more likely to lead to acute confusion in frail elderly persons. This effect can be reversed with
cholinesterase inhibitors such as physostigmine .uptodate
9.right answer is D . its high yield qz so learn its dd
Most problematic in the differential diagnosis of NMS, malignant catatonia shares clinical features of
hyperthermia and rigidity with NMS. However, in this syndrome, there is usually a behavioral prodrome of
some weeks that is characterized by psychosis, agitation, and catatonic excitement. The motor symptoms
are also characterized by more positive phenomena (dystonic posturing, waxy flexibility, and stereotyped
repetitive movements) than are described in NMS [47,48]. Laboratory values are more typically normal

10.ans is A
DIAGNOSIS — DSM-5 diagnostic criteria for borderline personality disorder are as follows [55]:
A. A pervasive pattern of instability of interpersonal relationships, self-image, and affects, and
marked impulsivity, beginning by early adulthood and present in a variety of contexts, as indicated
by five (or more) of the following:
1. Frantic efforts to avoid real or imagined abandonment. (Note: Do not include suicidal or selfmutilating behavior covered in Criterion 5.)
2. A pattern of unstable and intense interpersonal relationships characterized by alternating
between extremes of idealization and devaluation.
3. Identity disturbance: markedly and persistently unstable self-image or sense of self.
4. Impulsivity in at least two areas that are potentially self-damaging (eg, spending, sex,
substance abuse, reckless driving, binge eating). (Note: Do not include suicidal or selfmutilating behavior covered in Criterion 5.)
5. Recurrent suicidal behavior, gestures, or threats, or self-mutilating behavior.
6. Affective instability due to a marked reactivity of mood (eg, intense episodic dysphoria,
irritability, or anxiety usually lasting a few hours and only rarely more than a few days).
7. Chronic feelings of emptiness.
8. Inappropriate, intense anger or difficulty controlling anger (eg, frequent displays of temper,
constant anger, recurrent physical fights).
9. Transient, stress-related paranoid ideation or severe dissociative symptoms.
B. The enduring pattern is inflexible and pervasive across a broad range of personal and social
situations.
C. The enduring pattern leads to clinically significant distress or impairment in social, occupational,
or other important areas of functioning.
D. The pattern is stable and of long duration, and its onset can be traced back at least to
adolescence or early adulthood.
E. The enduring pattern is not better explained as a manifestation or consequence of another
mental disorder.
F. The enduring pattern is not attributable to the physiological effects of a substance (eg, a drug of
abuse, a medication) or another medical condition (eg, head trauma).
All nine of the DSM-5 diagnostic criteria are common in patients with BPD. The frequency of each
diagnostic criterion in a group of 201 patients with BPD was [56]:
●Affective instability (95 percent)
●Inappropriate anger (87 percent)
●Impulsivity (81 percent)
●Unstable relationships (79 percent)
●Feelings of emptiness (71 percent)
●Paranoia or dissociation (68 percent)
●Identity disturbance (61 percent)
●Abandonment fears (60 percent)
●Suicidality or self-injury (60 percent)
11. d is right
Behavioral features — The behavioral phenotype of boys with FXS shares features with ADHD,
anxiety, and autism spectrum disorder (eg, hyperactivity, inattention, gaze aversion, and stereotypic
movements, such as hand flapping, hyperarousal, social anxiety, unusual speech patterns)
HOX mutation lead to appendages in wrong location .this gene regulates fetal limb location ..
Other options are not associated with autism spectrm disorder
12.b is right answer ..here is why
DIAGNOSIS — Alcohol use disorder in DSM-5 replaces two psychiatric disorders in DSM-IV, alcohol
abuse and alcohol dependence. Alcohol use disorder can be specified as mild, moderate, or severe,
based on the number of DSM-5 criteria present. Alcohol dependence in DSM-IV is best represented by
moderate to severe alcohol use disorder in DSM-5; alcohol abuse is similar to the mild subtype of alcohol
use disorder.
DSM-5 diagnostic criteria for alcohol use disorder are [9]:
●Recurrent drinking resulting in failure to fulfill role obligations
●Recurrent drinking in hazardous situations
●Continued drinking despite alcohol-related social or interpersonal problems
●Evidence of tolerance
●Evidence of alcohol withdrawal or use of alcohol for relief or avoidance of withdrawal
●Drinking in larger amounts or over longer periods than intended
●Persistent desire or unsuccessful attempts to stop or reduce drinking
●Great deal of time spent obtaining, using, or recovering from alcohol
●Important activities given up or reduced because of drinking
●Continued drinking despite knowledge of physical or psychological problems caused by alcohol
●Alcohol craving
He has all the features according to DSM 5 .plus he has raisedESR MCV mean alcoholism main disorder
.other main distractor is primary insomnia but here are feature oof primary insomnia which is not present
in this patient
Diagnostic criteria — insomnia is confirmed when all four of the following criteria are met [1]:
●The patient reports difficulty initiating asleep, difficulty maintaining asleep, or waking up too early.
In children or individuals with dementia, the sleep disturbance may manifest as resistance to going
to bed at the appropriate time or difficulty in sleeping without caregiver assistance.
●Sleep difficulties occur despite adequate opportunity and circumstances for sleep.
●The patient describes daytime impairment that is attributable to the sleep difficulties. This may
include fatigue or malaise; attention, concentration, or memory impairment; social dysfunction,
vocational dysfunction, or poor school performance; mood disturbance or irritability; daytime
sleepiness; motivation, energy, or initiative reduction; errors or accidents at work or while driving;
and concerns or worries about sleep.
●The sleep-wake difficulty is not better explained by another sleep disorder.
13.he dnt have lithium toxicity and dnt have hyperthyroidism both ruled out by test …first line
treatment of adult onset essential tremor is propranolol ..so answer is H
14.answer is F .uptodate recommendations is
SUMMARY AND RECOMMENDATIONS
●For most presentations of specific phobia, we recommend first-line treatment with a cognitivebehavioral therapy (CBT) that includes exposure treatment over other psychotherapeutic or
pharmacologic interventions (Grade 1B). (See "Psychotherapy for specific phobia in adults".)
●When CBT/exposure is unavailable or when patients prefer medication to psychotherapy, we
suggest treatment of specific phobia with an infrequently encountered phobic stimulus with a
benzodiazepine. (Grade 2C). Benzodiazepine are best suited for patients who lack a history of a
substance-use disorder and for situations where the drug’s sedating effects do not interfere with
functioning (eg, as a passenger on a plane flight).
•A benzodiazepine lorazepam is used .The patient should take a test dose prior to using the
medication for the phobic situation to ensure it does not lead to oversedation. Patients should
be warned not to consume alcohol and the drug together due to the risk of additive side effects
such as sedation, confusion, and impaired coordinati'
●When CBT/exposure is unavailable or when patients prefer medication to psychotherapy, we
suggest treatment of specific phobia with a frequently encountered phobic stimulus with a selective
serotonin reuptake inhibitor (SSRI) (Grade 2C). As an example, sertraline can be started at
50 mg/day and titrated up to a therapeutic dose over two to three weeks.
See the difference requent and infrequent stimulus …amother point is SSRI would take long time to
take effect but he need to present in confrense in 2 days so u got it now .
15.right is D .
He dnt have hallucination in depressive time but when he is OKy with mood symptoms then he got
intermittent hallucination so that’s the core line to get in this ..he also dnt have dysthymia because
16 answer is C …she has 1.sad 2.weight loss 3.quiet 4.fatigue 5 ,negative feelings about herslf duration
more than 2 weeks .she dnt have illness anxiety disorder because feature of of illness anxiety disorder
=hypochondriosis are
She also dnt have delusional disorder somatic type because he has met all criteria for MDD so cant label
it as delusional …
17 .right ans is C .his age is less than 18 so conduct disorder is main diagnosis as he is assaultive in
nature ,oppositianal disorder dnt assault .
18 right answer after discussion is C
Here is recommendation of uptodate :
patients who continue to have insomnia that is severe enough to require an intervention, we
suggest cognitive behavioral therapy for insomnia (CBT-I) as the initial therapy
●For patients whose insomnia continues to be severe enough to require an intervention despite
CBT-I, we suggest the addition of a medication to CBT-I rather than changing to a strategy of
medication alone
●For patients who require medication for sleep onset insomnia, we suggest a short-acting
medication rather than a longer-acting agent
●For patients who require medication for sleep maintenance insomnia, we suggest a longer-acting
medication rather than a short-acting agent (Grade 2C). Alternatively, a formulation of zolpidem has
been approved for use in the middle of the night. Patients should be warned about the risk for
daytime drowsiness, impaired driving, dizziness, and lightheadedness
Biofeedback has no role in sleep disorder ,other best thing to do are following
Other drugs have no role in insomnia
19.answer is A
Diagnostic criteria — A number of criteria for the diagnosis of sCJD have been proposed [2,108-110].
Appropriate clinical and laboratory features generally are sufficient for a "probable" diagnosis of sCJD.
The Centers for Disease Control and Prevention (CDC) outline the following criteria for probable sporadic
CJD [111]:




Progressive dementia and
At least two out of the following four clinical features: myoclonus; visual or cerebellar
disturbance;pyramidal/extrapyramidal dysfunction; akinetic mutism and
Atypical electroencephalogram (EEG) during an illness of any duration, and/or a positive 14-3-3
cerebrospinal fluid (CSF) assay with a clinical duration to death less than two
years, and/or magnetic resonance imaging (MRI) high signal abnormalities in caudate
nucleus and/or putamen on diffusion-weighted imaging (DWI) or fluid attenuated inversion
recovery (FLAIR) and
Routine investigations should not suggest an alternative diagnosis
20 .here diagnosis is insomnia not MDD because he has only 2 feature of MDD so as I explained above
here treatment wl be first line CBT and next Zolpedim ..so answer is E
21.answer is B
Psychosis – Psychosis can occur but does so almost exclusively at doses of prednisone above
20 mg/day given for a prolonged period [7,77,78]. Approximately 10 percent of patients have persistent
symptoms that may require treatment despite reduction of glucocorticoid dose [79]. Response to
antipsychotic drug treatment is typically complete and occurs within two weeks of initiation of
neuroleptics. Hypoalbuminemia may be a risk factor for glucocorticoid-induced psychosis in patients with
SLE [80]. Patients with SLE who are on higher glucocorticoid doses present a particular problem, since it
is often difficult to differentiate psychosis due to prednisone from neuropsychiatric lupus, which may
require high-dose glucocorticoid treatment
He dnt have delirium as he is oriented to time place and person .
22.answer is F
treatment of acute catatonia generally occurs in hospital settings where the patient’s general
medical health can be monitored and optimized. Malignant catatonia in particular is life-threatening
and generally warrants admission to an intensive care unit.
●Concurrently treating the underlying psychiatric or general medical disorder along with the
catatonia may improve outcomes. Clinicians should avoid using dopamine blocking drugs, even if
patients are psychotic, impulsive, or aggressive. Treating catatonia with an antipsychotic is a risk
factor for the neuroleptic malignant syndrome (NMS). Antipsychotics are contraindicated in
malignant catatonia
●Mortality in malignant catatonia may increase if electroconvulsive therapy (ECT) does not begin
within five days of symptom onset. For patients with malignant catatonia, we recommend ECT rather
than a benzodiazepine (Grade 1C). A benzodiazepine should be administered during preparations
for ECT; if malignant catatonia improves significantly with the benzodiazepine during the first 24 to
48 hours, it can be continued in lieu of ECT.
23.answer is F ..full feature of panic unexpected attack
24. answer is D
UPTODATE SAYS
We recommend symptomatic treatment of psychosis with an antipsychotic medication, even if the specific
psychiatric disorder or medical condition underlying the psychosis has not yet been established (Grade
1B). As antipsychotic drugs are largely similar in efficacy, selection among them is typically made on the
basis of patient presentation and the medication’s side effect profile, cost, and formulations available
25.answer is C ..he has all typical features of child abuse ..and closed

26.b .enlarged ventricles in schizophrenia
Temporal spikes occurs in temporal lobe epilepsy
27.answer is c.he has normal finding all except temperature so may be
he is having factitious or malingering behavior so test Temperature
under supervision
28 . For pregnant patients with mild to moderate major depression, we suggest interpersonal
psychotherapy or cognitive-behavioral therapy (CBT) as initial treatment, rather than
pharmacotherapy (Grade 2B). However, pharmacotherapy is a reasonable choice if psychotherapy
is not successful, or is declined or not available. In addition, antidepressants can be used for
patients who responded to medications for past episodes of depression and patients with a past
history of severe depression. Adjunctive exercise may possibly help as well
●Patients and clinicians must weigh the risks of fetal exposure to medications against the maternal
and fetal risks of untreated illness. The risks of medications during pregnancy include teratogenicity,
miscarriage, spontaneous preterm birth, low birth weight, and postnatal effects. The risks of
untreated illness include missed obstetrical appointments; anorexia, suicidality, and other
depressive symptoms; and comorbid substance use disorders.

Schizoid Personality :A pervasive pattern of detachment from social relationships and a
restricted range of expression of emotions in interpersonal settings, beginning by early
adulthood and present in a variety of contexts, as indicated by four (or more) of the
following:
1.Neither desires nor enjoys close relationships, including being part of a family
2.almost always chooses solitary activities
3.has little, if any, interest in having sexual experiences with another person
4.takes pleasure in few, if any, activities
5.lacks close friends or confidants other than first-degree relatives
6.appears indifferent to the praise or criticism of others
7.shows emotional coldness, detachment, or flattened affectivityClinical Features of
Schizotypal Personality Disorder
1.These patients often display peculiarities in thinking, behavior and communication
2.Discomfort in social situations, and inappropriate behavior may occur.
3.Magical thinking, belief in "extra sensory perception", illusions and derealization are
common.
4.Familiarity does not decrease social anxiety since it is based on paranoid concerns
and not self-consciousness.
5.The patient may have a vivid fantasy life with imaginary relationships.
6.Speech may be idiosyncratic such as unusual use of phrasing or terminology.as in this
patient speech is stilted
So schizotypal here wl be right
32.diagnosis is Tourette syndrome
Treatment is tetrabenzene according to uptodate and uw say antipsychotics ,,so F is
answer here
33 answer is b .First line treatment for post traumatic stress disorder is CBT and in
CBT we explain all range of features after trauma …although it has many things in CBT
click CBT not group therapy
34 .she has generalized anxiety disorder .so first line is SSRI and CBT both have same
efficacy .For patients who experience a partial response to the maximally tolerated SsRI dose (or no
response to two SRIs), we suggest augmentation of the SRI with buspirone rather than other medication
Here reasonable option is buspiron …..bupropion is given for depression untreated with SSRI
35 .her BMI is low so strt parentral nutrition because without this she
is going to collapse ..at the moment she is also having hypotention
36 .ans is D .atpyical depression with weight gain and increased sleep

because all her investigation are negative ,when symptom persist
despite all negative evaluation by test then psychiatric assesment is
next step so ans is B
41 .ans is F ..he has headache due to sleep related hypoventilation
morning headache is due to increased CO2 accumulation in sleep due
to closed glottis in this obese boy … Morning headaches are reported by 10 to 30
percent of patients with untreated OSA [7,8]. They are usually bifrontal and squeezing in quality, with no
associated nausea, photophobia, or phonophobia. They typically occur daily or most days of the week
and may last for several hours after awakening in the morning. The cause of the headaches is not well
established and may be multifactorial; proposed mechanisms include hypercapnia, vasodilation,
increased intracranial pressure, and impaired sleep quality. Some studies have identified higher OSA
disease severity as a predictor of headache, although this has not been consistent [8-10]. The headaches
usually resolve completely within several weeks of initiating positive airway pressure therapy; lack of
improvement may suggest an alternative cause of headache
42. Patients taking clozapine should receive routine weekly-to-monthly monitoring and maintain an
neutrophil ≥1500/microL(≥1000/microL for benign ethnic neutropenia). Lower ANC levels require more
frequent monitoring, and possible interruption of clozapine and/or reevaluation of its use.
In this case Neutrophil is in lower limit plus symptomatic so temporary interruption is next best step
43.fetal alcohlic syndrome is right ..large only does not confirm that he has fragile x syndrome ..all other
