Diseases and Health Risk Factors Questions

Multiple choice

What can be the cause of drug addiction?

Directions: Read the passage and answer the question that follows.

Drug Addiction is one of the serious problems of the present times. Narcotics like heroin, hashish, and brown-sugar are commonly called drugs and young men and women either take these drugs orally or inhale their smoke.

Sociologist says that drug addiction is an addiction which has come to India and other oriental countries from the western countries. The Indians are aping the west and becoming drug-addicts. In the modern society, there are several family-problems. The lack of love and affection forces youths to get addicted to drugs. Sometimes, the pressure of addicted friends tempts the youth to become an addict.

Psychologists say that drugs help the addict to escape from the strains and problems of the world. But they damage the nervous system tremendously and shatter the mental make-up of the addicts. It even causes death. Even if the addict gives up taking drugs suddenly, he may die. So, withdrawal must be done gradually.

Drug addicts must be treated with love and kindness. The society should take strong measures to control dishonest businessmen and drug-traffickers. There are laws of drug-control all over the world, yet drug addiction is increasing gradually. What is needed is an anti-drugs consciousness among the youth of the different countries.

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

High blood pressure (hypertension) is called the 'silent killer' because it typically has no symptoms until it causes serious damage to organs like the heart, brain, and kidneys. Millions of people have hypertension without knowing it. Low blood pressure (hypotension) is not typically lethal. Leukemia is blood cancer, and diabetes is an endocrine disorder - neither are called 'silent killers' in medical terminology.

Multiple choice

Most common tumor in NF-1 is

  1. astrocytoma

  2. optic tract glioma

  3. glioblastoma multiforme

  4. none of these

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Optic pathway gliomas (including optic nerve and optic tract gliomas) are the most common tumors associated with Neurofibromatosis type 1 (NF-1), occurring in 15-20% of patients. They are typically low-grade pilocytic astrocytomas. While astrocytomas can occur in NF-1, the optic pathway glioma is the most characteristic and frequent. Glioblastoma is not associated with NF-1.

Multiple choice

Primary Pulmonary Hypertension is caused by all, except

  1. hyperventilation

  2. morbid obesity

  3. fenfluramine

  4. high altitude
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Primary pulmonary hypertension can be caused by morbid obesity, fenfluramine use, and high altitude due to hypoxic pulmonary vasoconstriction. Hyperventilation causes respiratory alkalosis and decreased pulmonary vascular resistance, which would lower pulmonary artery pressure, not cause pulmonary hypertension. Therefore, hyperventilation is the exception among the options.

Multiple choice

Which of the following is not true about Ogilive's syndrome?

  1. It is caused by mechanical obstruction of the colon.

  2. It involves entire/part of the large colon.

  3. It occurs after previous surgery.

  4. It occurs commonly after narcotic use.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ogilvie's syndrome (acute colonic pseudo-obstruction) is characterized by massive colonic dilation without mechanical obstruction. The key feature is that there is NO mechanical blockage - it's a functional motility disorder. It commonly occurs after surgery, trauma, or with narcotic use. The involvement can be of the entire colon or segments. The statement that it is caused by mechanical obstruction is therefore FALSE, making option A the correct answer to this 'NOT true' question.
