P.6 • Topic 9 Question 6 of 24

1 Mark • UNEB Standard

What is formed when soap is used in hard water instead of a lather?

💡 UNEB Examiner Insight & Textbook Rationale

The calcium and magnesium ions in hard water react with soap to form an insoluble gray precipitate called scum.

P.6 • Topic 10 Question 7 of 24

1 Mark • UNEB Standard

What is the immediate First Aid given to a person who has suffered a burn or a scald?

💡 UNEB Examiner Insight & Textbook Rationale

Pouring clean cold water rapidly cools skin tissue temperature, reduces pain and swelling, stops deeper cellular damage, and minimizes blister formation.

P.6 • Topic 10 Question 8 of 24

1 Mark • UNEB Standard

Why should a first aider NEVER induce vomiting in a casualty who has swallowed paraffin or kerosene?

💡 UNEB Examiner Insight & Textbook Rationale

Paraffin and acids are corrosive. If vomited, they re-burn the delicate lining of the gullet and can enter the lungs, causing chemical pneumonia.

P.6 • Topic 10 Question 9 of 24

1 Mark • UNEB Standard

What is the primary physiological cause of fainting in humans?

💡 UNEB Examiner Insight & Textbook Rationale

Fainting (syncope) occurs when cerebral blood flow is temporarily reduced, depriving brain cells of oxygen.

P.6 • Topic 10 Question 10 of 24

1 Mark • UNEB Standard

Why are the legs of a fainted casualty elevated higher than their head during First Aid?

💡 UNEB Examiner Insight & Textbook Rationale

Raising the legs uses gravity to rush venous blood from the lower extremities directly back to the heart and brain.

P.6 • Topic 10 Question 11 of 24

1 Mark • UNEB Standard

Why must a first aider NEVER burst blisters formed on a burn injury?

💡 UNEB Examiner Insight & Textbook Rationale

Unbroken blisters keep airborne bacteria away from exposed deep dermis cells. Piercing them opens the door to severe bacterial infections.

P.6 • Topic 10 Question 12 of 24

1 Mark • UNEB Standard

What should you do if an insect crawls inside a person's ear canal?

💡 UNEB Examiner Insight & Textbook Rationale

1 Mark • UNEB Standard

What is the scientific function of the wire mesh screen fitted on top of a VIP latrine vent pipe?

💡 UNEB Examiner Insight & Textbook Rationale

Flies in the dark pit fly toward the light at the top of the vent pipe, get trapped by the screen, and eventually die of starvation.

P.6 • Topic 11 Question 14 of 24

1 Mark • UNEB Standard

Why is the squat hole of a Ventilated Improved Pit (VIP) latrine left open without a lid at all times?

💡 UNEB Examiner Insight & Textbook Rationale

Leaving the squat hole open enables continuous convection currents: cool fresh air is pulled down the hole, driving warm foul air up through the vent pipe.

P.6 • Topic 11 Question 15 of 24

1 Mark • UNEB Standard

How does the Ecosan latrine benefit local crop farmers?

💡 UNEB Examiner Insight & Textbook Rationale

The Ecosan latrine uses ash or lime to dehydrate human waste and destroy bacteria, turning it into rich organic fertilizer for gardens.

P.6 • Topic 11 Question 16 of 24

1 Mark • UNEB Standard

What is the function of the U-trap pipe in a water closet (flush toilet)?

💡 UNEB Examiner Insight & Textbook Rationale

1 Mark • UNEB Standard

Why should chemical insecticides NEVER be poured into an ordinary pit latrine?

P.6 • Topic 12 Question 19 of 24

1 Mark • UNEB Standard

At which exact site in the female human reproductive system does fertilization take place?

💡 UNEB Examiner Insight & Textbook Rationale

Fertilization strictly occurs in the Oviduct (Fallopian tube). The Uterus is the site where the embryo implants and develops during pregnancy.

P.6 • Topic 12 Question 20 of 24

1 Mark • UNEB Standard

How is the function of anthers in a flowering plant similar to the function of testes in a human male?
