Diazonium ions are
Correct Answer
A. Weakly electropHilic
Explanation
Diazonium ions are weakly electrophilic because they have a positive charge on the nitrogen atom, making it electron-deficient. This makes the diazonium ion more likely to accept electrons from a nucleophile, rather than donate electrons, which is characteristic of electrophiles. Therefore, diazonium ions are considered weak electrophiles.
2.
Which of the following is not the component of white blood cells.
Correct Answer
B. Platelets
Explanation
Platelets are not a component of white blood cells. Platelets, also known as thrombocytes, are small cell fragments that are involved in blood clotting. They are produced in the bone marrow and play a crucial role in stopping bleeding by forming clots at the site of injury. White blood cells, on the other hand, are responsible for fighting off infections and diseases. The components of white blood cells include neutrophils, monocytes, and basophils, which are all involved in the immune response. Therefore, platelets do not belong to the category of white blood cells.
3.
Which type of hypersensitivity reaction has cell-mediated (delayed) type of action.
Correct Answer
D. Type IV Hypersensitivity
Explanation
Type IV Hypersensitivity is the correct answer because it involves a cell-mediated (delayed) immune response. Unlike the other types of hypersensitivity reactions, which are antibody-mediated, Type IV Hypersensitivity is characterized by the activation of T cells and the release of cytokines. This type of reaction typically takes 24-72 hours to develop after exposure to the antigen, hence the term "delayed" type of action. Examples of Type IV Hypersensitivity include contact dermatitis, tuberculin skin test reactions, and graft rejection.
4.
The confirmation of AIDS is done by one of the following tests.
Correct Answer
B. Western Blot
Explanation
The Western Blot test is used to confirm the presence of AIDS. This test detects specific antibodies in the blood that are associated with the HIV virus. It is often used as a follow-up test after a positive ELISA result to ensure accuracy. PCR test is used to detect the presence of the virus itself, while Southern blot is not commonly used for HIV diagnosis. Therefore, the Western Blot test is the most appropriate choice for confirming AIDS.
5.
Ototoxicity and Nephrotoxicity are selective toxicities of
Correct Answer
C. Aminoglycosides
Explanation
Aminoglycosides have the selective toxicities of ototoxicity and nephrotoxicity. Ototoxicity refers to the potential damage to the inner ear, leading to hearing loss and balance problems. Nephrotoxicity, on the other hand, refers to the potential damage to the kidneys, which can result in impaired kidney function. These specific toxicities are associated with aminoglycoside use, making it the correct answer. Penicillins, cephalosporins, and quinolones do not typically exhibit these specific toxicities.

N-acetyl-P-benzoquinone imine, a metabolite of paracetamole causes
Correct Answer
B. Hepatic necrosis
Explanation
N-acetyl-P-benzoquinone imine, a metabolite of paracetamol, is known to cause hepatic necrosis. This means that it can lead to liver damage and cell death in the liver. Paracetamol is a commonly used medication for pain relief and fever reduction, but excessive or prolonged use can result in the accumulation of this toxic metabolite, leading to liver toxicity. Therefore, it is important to use paracetamol within the recommended dosage and duration to avoid the risk of hepatic necrosis.
7.
The time a drug takes to reach an effective concentration or steady state level depends on its
Correct Answer
C. Rate of elimination from the body
Explanation
The time a drug takes to reach an effective concentration or steady state level depends on its rate of elimination from the body. This is because the rate of elimination determines how quickly the drug is cleared from the body, which in turn affects the concentration of the drug in the bloodstream. If the rate of elimination is slow, it will take longer for the drug to reach an effective concentration. Conversely, if the rate of elimination is fast, the drug will be cleared from the body more rapidly and may not reach an effective concentration.
8.
Diazepam is a drug of choice used in the management of
Correct Answer
C. Status epilepticus
Explanation
Diazepam is a drug of choice used in the management of status epilepticus. Status epilepticus is a medical emergency characterized by prolonged seizures or multiple seizures without full recovery of consciousness between them. Diazepam is a benzodiazepine that works by enhancing the effects of a neurotransmitter called GABA, which helps to calm excessive electrical activity in the brain. It is commonly used to stop or prevent seizures in status epilepticus cases due to its fast onset of action and effectiveness in suppressing seizure activity.
9.
The mechanism of action of doxorubicin is
Correct Answer
B. It stabilizes DNA-Topoisomerase-II
Explanation
Doxorubicin stabilizes DNA-Topoisomerase-II. DNA-Topoisomerase-II is an enzyme responsible for unwinding DNA during replication and transcription. Doxorubicin binds to the DNA-Topoisomerase-II complex and prevents it from resealing the DNA strands after unwinding, leading to the formation of DNA breaks. This ultimately inhibits DNA replication and transcription, resulting in the inhibition of cell division and the death of rapidly dividing cells, such as cancer cells.
10.
The antidot BAL is used to reduce toxicity of
Correct Answer
D. Mercury
Explanation
The antidote BAL is used to reduce the toxicity of mercury. BAL, also known as dimercaprol, is a chelating agent that binds to heavy metals like mercury, forming a complex that can be excreted from the body. It is commonly used in cases of mercury poisoning to help remove the toxic metal from the bloodstream and tissues, reducing its harmful effects on the body.
11.
Dry heat is often used to sterilize
Correct Answer
C. Oily Materials
Explanation
Dry heat is often used to sterilize oily materials because dry heat can effectively penetrate and destroy microorganisms, including bacteria, present in oily substances. Unlike moist heat, dry heat does not rely on water or steam to kill the microorganisms. Instead, it uses high temperatures to denature proteins and disrupt the cellular structure of the bacteria, ensuring their complete destruction. This makes dry heat an ideal method for sterilizing oily materials, as it can eliminate any potential contaminants without causing damage or degradation to the substance being sterilized.
12.
LAL can detect
Correct Answer
A. Endotoxin
Explanation
LAL (Limulus amebocyte lysate) is a test used to detect the presence of endotoxins, which are toxins produced by certain bacteria. Endotoxins are a component of the outer membrane of Gram-negative bacteria and can cause harmful effects when released into the bloodstream. The LAL test utilizes the clotting properties of horseshoe crab blood to detect the presence of endotoxins. Therefore, LAL can accurately detect the presence of endotoxins in a sample.
13.
The drug penicillins inhibits
Correct Answer
A. Cell wall synthesis
Explanation
Penicillins are a class of antibiotics that specifically target and inhibit the synthesis of bacterial cell walls. Bacterial cell walls are crucial for maintaining the structural integrity and protection of the bacteria. By inhibiting cell wall synthesis, penicillins weaken the bacterial cell wall, making it more susceptible to damage and ultimately leading to the death of the bacteria. This mechanism of action is what makes penicillins effective in treating bacterial infections.
