Norethindrone is a

A
Natural antibiotic

B
Synthetic antifertility drug

C
Synthetic disinfectant

D
Natural progesterone derivative

Solution

Norethindrone is synthetic infertility drug. Norethindrone is a form of progesterone, a female hormone important for regulating ovulation and menstruation. Norethindrone is used for birth control (contraception) to prevent pregnancy. Norethindrone is also used to treat menstrual disorders, endometriosis, or abnormal vaginal bleeding caused by a hormone imbalance.
Question 2

Barbiturates are important class of

A
Antibiotics

B
Tranquilisers

C
Anti –oxidants

D
Preservatives

Solution

Barbiturates are important class of Tranquilisers. Barbiturates affect your brain by increasing a brain chemical called gamma-aminobutyric acid (GABA), which slows down the activity of your brain cells .
Question 3
1 / -0.25

The effective medicine to be given to a person suffering from hyperacidity is

A
Cimetidine

B
Anacin

C
Seldane

D
A solution of sodium –bicarbonate

Solution

Cimetidine is an antacids as they control the root cause of acidity These drugs prevent the interaction of histamine with the receptors present in the stomach walls Consequently there is a decrease in the amount of acid release by the stomach
Question 4
1 / -0.25

Anti –histamines stop allergic reactions by

A
competing with histamine for binding sites of histamine receptor

B
inhibiting histamine production

C
reacting with allergy reactions orally

D
reacting with the allergens like pollen

Solution

Anti –histamines stop allergic reactions by competing with histamine for binding sites of histamine receptor.
Question 5
1 / -0.25

Ortho –sulphobenzimide is

A
An anti –oxidant

B
A preservative

C
An antibiotic

D
An artificial sweetner

Solution

Sodium saccharin (benzoic sulfimide) is an artificial sweetener with effectively no food energy. It is about 300 –400 times as sweet as sucrose but has a bitter or metallic aftertaste, especially at high concentrations. Saccharin is used to sweeten products such as drinks, candies, cookies, and medicines.
Question 6
1 / -0.25

The element in soap which makes it soft on skin is

A
Sodium

B
Potassium

C
Calcium

D
Magnesium

Solution

Depending on the intended application of the soap , sodium hydroxide or potassium hydroxide is generally used as an alkali. If potassium hydroxide is used, it produces a more water-soluble product than its sodium-based counterpart, and is thus often called “soft soap ”.
Question 7
1 / -0.25

Scum formation can be prevented by

A
using detergents

B
using water softeners

C
using soft water

D
All of these

Solution

Scum formation happens in hard water. It can be avoided by adding water softners or by using detergents.
Question 8
1 / -0.25

The colloidal soap is precipitated by

A
Adding sodium chloride

B
Cooling the colloidal soap solution

C
Boiling the colloidal soap solution

D
Centrifuging the colloidal solution

Solution

Colloidal soap is precipitated by adding NaCl. Sodium chloride is added to precipitate soap after saponficiation because hydrolysis of esters of long chain fatty acids by alkali produces soap in colloidal form .
Question 9
1 / -0.25

Chloramphenicol is used to treat typhoid, dysentery, acute fever, meningitis etc., because it is

A
Bactericidal and narrow spectrum antibiotic

B
Bacteriostatic and broad spectrum antibiotic

C
Bacteriostatic and narrow spectrum antibiotic

D
Bactericidal and broad spectrum antibiotic

Solution

Chloramphenicol treats typhoid, dysentery, acute fever, meningitis etc.,as it is Bacteriostatic and broad spectrum antibiotic.
Question 10
1 / -0.25

Drugs, which inhibit the enzymes that catalyze the degradation of noradrenaline, are

A
Antihistamine

B
Analgesics

C
Antidepressant drugs

D
Anti –fertility

Solution

Anti-depressant drugs are needed to cure this problem. They inhibit enzymes that catalyze noradrenaline degradation . Hence, the metabolism of noradrenaline is slowed down and the neurotransmitter can activate its receptor for longer periods of time. Iproniazid and phenelzine are two such drugs .
Question 11
1 / -0.25

Persons allergic to Penicillin can be given

A
Sulpha drugs

B
Non –narcotic drugs

C
Psychotherapeutic drugs

D
Narcotic drugs

Solution

Sulpha drugs is given to treat people who are allergic to pencillin.
Question 12
1 / -0.25

Sodium –bicarbonate is not a preferred antacid because

A
It causes irritation and pain

B
It is insoluble in water

C
It is a very mild antacid

D
It increases the pH above neutrality

Solution

NaHCO₃ is basic and it increases ph above neutrality.
Question 13
1 / -0.25

Enzyme inhibitor drugs

A
Allows the substrate to bind with the enzyme at the allosteric site

B
Attaches itself to the substrate changing the shape of the substrate

C
Allow enzymes to bind strongly to the substrate by hydrogen bonding

D
Form a strong covalent bond between itself and enzyme

Solution

Both option b and d are correct. Enzyme inhibitors drugs can block the binding site of the enzyme and prevent the binding of substrate, or can inhibit the catalytic activity of the enzyme.
Question 14
1 / -0.25

Liquid dishwashing agents are

A
Soaps

B
Cationic Detergents

C
Non –ionic Detergents

D
Anionic Detergents

Solution

Liquid dishwashing agents are non ionic detergents. Since the detergent does not have any ionic groups,it does not react with hard water ions but can remove grease and oil by micelle formation.
Question 15
1 / -0.25

Zantac, Cimetidine, Ranitidine are all

A
Antibiotics

B
Antacids

C
Analgesics

D
Antapyretics

Solution

Cimetidine,zantac and ranitidine are antacids as they control the root cause of acidity These drugs prevent the interaction of histamine with the receptors present in the stomach walls Consequently there is a decrease in the amount of acid release by the stomach
