Question 1

Retrolental fibroplasia is a complication of:

Accepted Answer

Oxygen therapy

Answer

Retrolental fibroplasia (retinopathy of prematurity) is caused by excess oxygen therapy in premature infants, where high oxygen concentrations damage developing retinal blood vessels, leading to abnormal vascular growth and potential blindness. Chemotherapy, radiotherapy, and physiotherapy do not target the retinal vasculature in this way, and hydrotherapy has no association with this condition.

Question 2

"Heparin effect is neutralized by:

Accepted Answer

Protamine Sulphate

Answer

Protamine sulphate is the specific antidote for heparin — it is a positively charged protein that directly binds and neutralizes negatively charged heparin molecules, reversing anticoagulation. Streptokinase and tissue plasminogen activator are actually thrombolytics that have the opposite effect, while phenylbutazone is an NSAID with no reversal action on heparin.

Question 3

The most common breast tumor is:

Accepted Answer

Fibroadenoma

Answer

Fibroadenoma is the most common benign breast tumor, occurring most frequently in women aged 15–35 as a firm, mobile, non-tender lump. The other options — papillary carcinoma, medullary carcinoma, inflammatory carcinoma, and infiltrating ductal carcinoma — are all malignant and far less common overall.

Question 4

Regarding osteoarthritis which of the following is true?

Accepted Answer

Joint pain is precipitated by exertion

Answer

In osteoarthritis, joint pain characteristically worsens with activity (exertion) and improves with rest, due to cartilage degeneration under mechanical stress. Osteoarthritis typically affects large weight-bearing joints (not small joints), is more common in women (especially post-menopausal), is associated with obesity rather than athletic build, and generally presents after age 40.

Question 5

3 months after a measles infection a 7 year old boy develops seizure, the most likely diagnoses is?

Accepted Answer

Subacute sclerosing disease

Answer

Subacute Sclerosing Panencephalitis (SSPE) is a rare, progressive fatal neurological disorder caused by persistent measles virus infection of the brain, typically presenting months to years after the initial measles infection with seizures and cognitive decline. Phenylketonuria and maple syrup urine disease are metabolic disorders present from birth, subarachnoid hemorrhage has a vascular cause, and febrile seizures occur with acute fever — none follow a prior measles infection.
