Q1 · 2026

The following are the stages of life cycle of Plasmodium. Arrange the stages in the proper order.

A. The parasites reproduce asexually in RBCs, bursting the cells.

B. The parasites reproduce asexually in liver cells, bursting the cells and releasing into blood.

C. Gametocytes develop in RBCs.

D. Sporozoites reach the liver through the blood.

E. Female mosquito injects sporozoites into humans during bite.

Choose the correct answer from the options given below:

  • A.

    E, D, B, A, C

  • B.

    A, B, C, D, E

  • C.

    C, A, B, D, E

  • D.

    E, C, D, B, A

Answer: A

  1. Recall the Plasmodium life cycle sequence in the human host, which begins with the mosquito bite and ends with the formation of gametocytes.

  2. Understand the starting point — infection begins when a female Anopheles mosquito injects sporozoites into a human during a bite (step E).

  3. Trace the path of the sporozoites — after entering the body, the sporozoites travel through the blood and reach the liver (step D).

  4. Recognize the asexual multiplication in the liver — inside liver cells, the parasites multiply asexually, and when these cells burst, the parasites are released into the blood (step B).

  5. Recognize the asexual multiplication in RBCs — the released parasites then infect RBCs, multiply asexually, and burst the RBCs, causing the characteristic fever cycles (step A).

  6. Recognize the formation of the sexual stage — some parasites inside RBCs transform into gametocytes, the sexual stage, ready to be picked up by another mosquito (step C).

  7. Hence, the correct order is E, D, B, A, C (Option A).

Q2 · 2026

Match List I with List II:

List I (Drug)List II (Effect)
A. NicotineI.Causes sense of euphoria and increased energy
B. MorphineII.Stimulates adrenal gland to release catecholamines into blood circulation
C. HeroinIII.Effective sedative and painkiller
D. CocaineIV.A depressant; slows down body function

Choose the correct answer from the options given below:

  • A.

    A-III, B-II, C-IV, D-I

  • B.

    A-II, B-III, C-I, D-IV

  • C.

    A-II, B-III, C-IV, D-I

  • D.

    A-III, B-II, C-I, D-IV

Answer: C

  1. Recall the pharmacological effects of each drug listed.

  2. Match Nicotine — it stimulates the adrenal gland to release catecholamines (adrenaline and noradrenaline) into the blood, so A → II.

  3. Match Morphine — it is an opioid that acts as an effective sedative and painkiller, so B → III.

  4. Match Heroin — it acts as a depressant that slows down body functions, so C → IV.

  5. Match Cocaine — it acts as a stimulant, producing a sense of euphoria and increased energy, so D → I.

  6. Hence, the correct matching is A-II, B-III, C-IV, D-I (Option C).

Q3 · 2026

Which of the following is used as an effective sedative and painkiller for treating post-surgery patients?

  • A.

    Anti-retroviral drugs

  • B.

    Interferon

  • C.

    Antibiotics

  • D.

    Morphine

Answer: D

  1. Understand what the question is asking — we need to identify a drug that acts as a sedative and painkiller for patients recovering from surgery.

  2. Recall that Morphine is an opioid analgesic that acts as an effective sedative and painkiller, and is widely used to manage pain in post-surgery patients.

  3. Eliminate the other options: Interferon is a cytokine that forms part of the innate immune barrier against viruses, not a painkiller. Antibiotics restrict bacterial growth and treat infections, not pain. Anti-retroviral drugs are used to treat viral infections such as HIV, not pain.

  4. Hence, the answer is Morphine (Option D).
