Occupational Therapy in Low Vision Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Occupational Therapy in Low Vision. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Occupational Therapy in Low Vision Indian Medical PG Question 1: A patient complains of loss of visual acuity, deafness, and enlargement of the maxilla.
- A. Fibrous dysplasia
- B. Osteogenesis imperfecta
- C. Paget's disease (Correct Answer)
- D. Osteomalacia
Occupational Therapy in Low Vision Explanation: ***Paget's disease*** [1]
- Characterized by abnormal **bone remodeling**, leading to an increase in bone size and deformity, particularly in the **maxilla**, causing enlargement [1].
- Associated with complications such as **loss of visual acuity** (due to involvement of the skull) and **deafness** from auditory canal changes [1][2], making this the most fitting diagnosis.
*Fibrous dysplasia*
- Typically presents with **fibrous replacement** of bone, not specifically causing deafness or visual acuity loss.
- Customarily involves the **classic "ground glass" appearance** on imaging, not the structural enlargement seen in Paget's disease.
*Osteogenesis imperfecta*
- Mainly causes **brittle bones** and frequent fractures, not associated with **maxillary enlargement** or changes in auditory function.
- Rarely causes visual acuity loss, which is not a feature of this condition.
*Osteomalacia*
- Primarily characterized by **softening of bones** due to vitamin D deficiency, leading to weakness rather than structural changes like maxillary enlargement.
- Symptoms like **bone pain** or **muscle weakness** occur, but not specifically loss of auditory function or visual acuity.

Occupational Therapy in Low Vision Indian Medical PG Question 2: A 20-year-old girl complains of headache while studying. Her vision is found to be normal. In the initial medical evaluation of her headache, which of the following would be the LEAST essential to assess?
- A. Family history of headache
- B. Menstrual history
- C. Fundoscopy examination
- D. Her interest in studies (Correct Answer)
Occupational Therapy in Low Vision Explanation: ***Her interest in studies***
- While **stress** and **academic pressure** can contribute to headaches, this represents a **psychosocial assessment** rather than a standard medical evaluation.
- Among the listed options, this would be the **least essential** in the initial medical workup compared to the other clinical assessments.
*Family history of headache*
- Essential evaluation as many headache disorders, particularly **migraine** and **tension-type headache**, have strong **genetic predisposition**.
- Family history helps establish diagnosis and guides appropriate management strategies for the patient's headaches.
*Menstrual history*
- Crucial in young women as **hormonal fluctuations** during the menstrual cycle are major triggers for headaches, especially **menstrual migraine**.
- Understanding menstrual patterns can identify cyclical headache triggers and inform treatment approaches.
*Fundoscopy examination*
- Important to rule out **papilledema** (optic disc swelling) and signs of **increased intracranial pressure**, even with normal visual acuity.
- Normal vision does not exclude underlying pathology that could be detected through **ophthalmoscopic examination** of the retina and optic nerve.
Occupational Therapy in Low Vision Indian Medical PG Question 3: Under Vision 2020, to check visual acuity, a teacher will refer a school child to
- A. Centre for excellence
- B. Vision centre (Correct Answer)
- C. Training centre
- D. Service centre
Occupational Therapy in Low Vision Explanation: ***Vision centre***
- Under Vision 2020 initiatives, a **Vision Centre** serves as the primary point of contact for basic ophthalmic services, including **visual acuity screening** and referral.
- These centers are designed to be accessible in local communities, allowing teachers and other local caregivers to refer school children for initial checks and appropriate management.
*Centre for excellence*
- A **Centre for Excellence** typically refers to a highly specialized institution with advanced diagnostic and treatment capabilities, research facilities, and complex surgical procedures, which is **beyond the scope** of basic visual acuity checking and initial referral.
- Such centers handle more **complex or rare conditions** and are not the first point of contact for routine school-based screening.
*Training centre*
- A **Training Centre** is primarily dedicated to educating and skilling healthcare professionals, not to providing direct patient care or screening services to the general public.
- While essential for developing skilled personnel, it is **not the appropriate facility** for a teacher to refer a child for a visual acuity check.
*Service centre*
- The term **Service Centre** is too broad and can refer to various types of facilities that provide any kind of service, but it does not specifically denote a healthcare facility for ophthalmic care under the Vision 2020 program.
- It lacks the **specific medical context** and structured role established for vision screening.
Occupational Therapy in Low Vision Indian Medical PG Question 4: Best therapy suited to teach daily life skills to a child with intellectual disability:
- A. Applied Behavior Analysis (ABA) (Correct Answer)
- B. Cognitive Behavioral Therapy (CBT)
- C. Social skills training
- D. Self-instructional training
Occupational Therapy in Low Vision Explanation: **Applied Behavior Analysis (ABA)**
- **ABA** is a highly structured, evidence-based therapy that focuses on teaching specific skills by breaking them down into smaller steps and using **positive reinforcement**.
- It is particularly effective for children with intellectual disabilities in acquiring **adaptive daily living skills**, communication, and social behaviors.
*Cognitive Behavioral Therapy (CBT)*
- **CBT** primarily targets changing negative thought patterns and behaviors, requiring a level of abstract reasoning that may be challenging for children with significant intellectual disabilities.
- While it can be adapted, its core methods rely on cognitive processes that might not be the most direct approach for teaching basic daily life skills to a mentally challenged child.
*Social skills training*
- **Social skills training** focuses specifically on improving social interactions and communication within social contexts.
- While important for overall development, it is a subcomponent of broader skill development and may not directly address all aspects of **daily living skills** in a comprehensive manner.
*Self-instructional training*
- **Self-instructional training** involves teaching individuals to guide themselves through tasks using internal speech or self-talk, which relies on a child's ability to internalize and follow complex verbal instructions.
- This approach might be too cognitively demanding for a child with significant developmental delays when the primary goal is mastering basic, functional daily life skills.
Occupational Therapy in Low Vision Indian Medical PG Question 5: In which of the following patients would supportive therapy be most challenging to implement effectively?
- A. Patient who is severely ill and has significant ego dysfunction
- B. Person who is motivated and has good self-control
- C. Person with good cognitive and functional abilities
- D. Patient who is severely ill and uncooperative (Correct Answer)
Occupational Therapy in Low Vision Explanation: ***Patient who is severely ill and uncooperative***
- A **severely ill** patient who is **uncooperative** presents the most **immediate and direct barrier** to implementing supportive therapy effectively. Their **active resistance** to therapeutic interventions (refusing medication, declining to engage, missing appointments) makes it practically impossible to deliver care.
- **Uncooperativeness** represents active opposition to treatment, requiring resolution before any therapeutic work can proceed. Without patient engagement, even the most basic supportive interventions cannot be implemented.
- While other patients may have limitations, an uncooperative patient fundamentally blocks the therapeutic alliance necessary for any psychotherapy.
*Patient who is severely ill and has significant ego dysfunction*
- **Ego dysfunction** (impaired reality testing, poor impulse control, weak sense of self) is indeed challenging and represents a relative contraindication to insight-oriented therapies.
- However, patients with ego dysfunction may still **passively participate** in supportive therapy, especially when the therapy is structured and focused on basic stabilization rather than insight.
- The key difference: ego dysfunction is a **structural limitation** requiring adaptation of technique, whereas uncooperativeness is an **active barrier** preventing any intervention. A patient with ego dysfunction can still potentially benefit from modified supportive approaches, but an uncooperative patient cannot be engaged at all.
*Person who is motivated and has good self-control*
- This patient would be the **easiest to treat** with supportive therapy due to their intrinsic motivation and ability to manage their own behavior.
- Their **motivation** and **self-control** would facilitate adherence to treatment plans and active participation in their care, making implementation straightforward.
*Person with good cognitive and functional abilities*
- This patient would be **highly amenable to supportive therapy** as their cognitive and functional capacities allow them to understand and participate in treatment.
- Good cognitive and functional abilities enable them to comprehend instructions, manage their own care, and engage effectively with healthcare providers, presenting minimal implementation challenges.
Occupational Therapy in Low Vision Indian Medical PG Question 6: In infants of diabetic mothers (IDM), when is ophthalmologic evaluation indicated?
- A. At the time of diagnosis
- B. Only if visual symptoms develop (Correct Answer)
- C. After 5 years routinely
- D. After developing diabetes
Occupational Therapy in Low Vision Explanation: ***Only if visual symptoms develop***
- Unlike **retinopathy of prematurity**, infants of diabetic mothers (IDMs) do not have a higher incidence of **retinopathy** or other **ocular abnormalities** at birth or in early infancy.
- **Ophthalmologic evaluation** is generally reserved for IDMs who develop specific **visual symptoms** or signs of ocular pathology.
*At the time of diagnosis*
- Routine ophthalmologic screening at the time of diagnosis of IDM is **not standard practice**, as the risk of **congenital ocular anomalies** is not substantially elevated to warrant universal screening.
- Initial management focuses on metabolic stability, especially **glucose control**, and screening for other common IDM-related complications like **cardiac defects** or **respiratory distress**.
*After 5 years routinely*
- There is **no evidence or recommendation** for routine ophthalmologic screening of IDMs specifically at the age of 5 years.
- Regular **well-child check-ups** include basic vision screening, which would identify significant refractive errors or strabismus, but not specifically for diabetes-related ocular issues.
*After developing diabetes*
- While it is true that individuals with **type 1 or type 2 diabetes** require regular **ophthalmologic evaluations** for **diabetic retinopathy**, this refers to the child developing diabetes later in life, not being an IDM.
- Being an IDM is a **risk factor for developing diabetes** later in life, but it doesn't automatically mean they have diabetes-related ocular issues from birth.
Occupational Therapy in Low Vision Indian Medical PG Question 7: Bright light therapy is used for?
- A. Adjustment disorder
- B. Anxiety
- C. Schizophrenia
- D. Seasonal affective disorder (Correct Answer)
Occupational Therapy in Low Vision Explanation: ***Seasonal affective disorder***
- **Bright light therapy** is a primary treatment for **seasonal affective disorder (SAD)**, particularly **winter depression**, by simulating natural outdoor light.
- Exposure to bright light can help regulate the body's **circadian rhythm** and neurotransmitter levels, which are often disrupted in SAD.
*Adjustment disorder*
- This disorder is a **stress-related condition** where a person has difficulty coping with a specific stressor or event.
- Treatment typically involves **psychotherapy** and addresses the specific stressor, not light therapy.
*Anxiety*
- **Anxiety disorders** are characterized by excessive worry, fear, or apprehension.
- Treatment usually involves **cognitive behavioral therapy (CBT)**, medications (e.g., SSRIs), or a combination thereof, not bright light therapy.
*Schizophrenia*
- **Schizophrenia** is a chronic and severe mental disorder affecting how a person thinks, feels, and behaves, involving psychosis.
- Management primarily relies on **antipsychotic medications** and psychosocial interventions, with no established role for bright light therapy.
Occupational Therapy in Low Vision Indian Medical PG Question 8: A 40 year old male has vision of 6/60 in right eye and 3/60 in left eye under NPCB, he will be classified as:-
- A. Socially blind (Correct Answer)
- B. Economically blind
- C. Low vision
- D. Normal
Occupational Therapy in Low Vision Explanation: ***Socially blind***
- According to the **National Programme for Control of Blindness (NPCB)** criteria, visual acuity of **6/60 in the better eye** falls under the category of **blindness** (specifically, visual acuity <6/60 to 3/60).
- The term **"socially blind"** is sometimes used colloquially to describe individuals who meet the medical criteria for blindness but may retain some functional vision.
- In this case, the right eye (6/60) is the better eye, and 6/60 vision qualifies as blindness under NPCB guidelines, making "socially blind" the most appropriate classification among the given options.
*Low vision*
- **Low vision** under NPCB is defined as visual acuity **<6/18 to 6/60** in the better eye with best possible correction.
- Since this patient has exactly 6/60 in the better eye, they fall at the threshold between low vision and blindness.
- By strict NPCB criteria, **6/60 is classified as blindness**, not low vision (which requires vision better than 6/60).
*Economically blind*
- This is not a recognized formal classification under NPCB guidelines.
- NPCB criteria are based on visual acuity and visual field measurements, not economic considerations.
*Normal*
- Normal vision is typically 6/6 to 6/9.
- Vision of 6/60 and 3/60 is significantly impaired and does not qualify as normal.
Occupational Therapy in Low Vision Indian Medical PG Question 9: A patient with native aortic valve disease presents with right hemiparesis. What is the most appropriate management to prevent further strokes?
- A. Both antiplatelet and anticoagulant
- B. One dose of low molecular weight heparin sub-cutaneously followed by dual antiplatelet therapy
- C. Antiplatelet only
- D. Anticoagulant only (Correct Answer)
Occupational Therapy in Low Vision Explanation: ***Anticoagulant only***
- Patients with **native aortic valve disease** and **embolic stroke (like right hemiparesis)** are at high risk for further strokes if the emboli are cardiogenic in origin, often from valvular vegetations or abnormalities [1]. **Anticoagulants** are superior to antiplatelets in preventing recurrent **systemic embolization** from cardiac sources.
- While the specific cause of the aortic valve disease isn't stated (e.g., infective endocarditis, nonbacterial thrombotic endocarditis, or calcific aortic stenosis with mobile thrombus), **anticoagulation** is generally the preferred strategy in this context to prevent further **thromboembolic events**.
*Antiplatelet only*
- **Antiplatelet agents** (e.g., aspirin, clopidogrel) primarily prevent arterial clots formed on atherosclerotic plaques and are less effective for preventing **cardiogenic emboli** originating from valvular disease.
- Relying solely on antiplatelet therapy in this scenario would leave the patient at a higher risk for recurrent strokes from the underlying **cardiac source** [1].
*Both antiplatelet and anticoagulant*
- While some conditions warrant combination therapy (e.g., after certain cardiac procedures or in specific acute coronary syndromes), adding an **antiplatelet agent** to an **anticoagulant** significantly increases the risk of **bleeding** without providing substantial additional benefit for preventing stroke in the context of native aortic valve disease as the primary stroke mechanism.
- The increased **bleeding risk** generally outweighs the potential benefit for preventing future strokes when the primary etiology points to cardiogenic embolism.
*One dose of low molecular weight heparin sub-cutaneously followed by dual antiplatelet therapy*
- A single dose of **LMWH** provides short-term anticoagulation and is not sufficient for long-term stroke prevention in a patient with ongoing risk from native aortic valve disease.
- **Dual antiplatelet therapy (DAPT)** is indicated in other contexts (e.g., after stent placement) but is not the appropriate long-term strategy for preventing **cardiogenic strokes** from valvular disease, where anticoagulation is paramount.
Occupational Therapy in Low Vision Indian Medical PG Question 10: In which context can helium replace nitrogen as a diluent gas in oxygen mixtures?
- A. Argon
- B. Xenon
- C. Helium
- D. None of the options (Correct Answer)
Occupational Therapy in Low Vision Explanation: **None of the options**
- This question implies that helium might replace *another noble gas* as a diluent, but the correct application is for helium to replace **nitrogen** in oxygen mixtures, particularly in **diving applications**. This question likely has a flaw in its premise if expecting one of the noble gases listed to be the 'replacement' for nitrogen, as helium *is* the replacement.
- Helium is used instead of nitrogen in diving gases (**trimix, heliox**) for deep dives because it is less narcotic than nitrogen under pressure, reducing the risk of **nitrogen narcosis**.
*Argon*
- **Argon** is denser than nitrogen and has a higher narcotic potential at depth, making it unsuitable as a replacement for nitrogen in diving gases.
- It is sometimes used during **dry suit inflation** for insulation due to its low thermal conductivity, but not as a breathing gas diluent.
*Xenon*
- **Xenon** is a potent anesthetic agent, even at atmospheric pressure, due to its high lipid solubility.
- Its use as a diluent would cause severe **narcosis** and render a diver unconscious, making it entirely inappropriate for diving mixtures.
*Helium*
- While helium is indeed the gas that replaces nitrogen as a diluent in oxygen mixtures for deep diving, it being listed as an option here suggests a misunderstanding of the question's phrasing. The question is asking for **in which context** helium can replace nitrogen, not asking to identify helium itself as the replacement.
- Given the other options are noble gases that *cannot* replace nitrogen in this context, "None of the options" is the most accurate answer if the question implies picking from the provided list for a replacement *for helium* or a suitable *alternative* to helium, which isn't the case here.
