Free Funeral Service Questions and Answers — Questions and Answers
Question 1: Which of the following is the reference point for determining how effective chemical disinfectants are?
- Formalin (Methanol)
- Alcohol
- Bichloride of Mercury
- Phenol (Correct answer)
Correct answer: Phenol
Phenol is historically used as the standard reference point for evaluating the effectiveness of other chemical disinfectants. The 'Phenol Coefficient' is a measure that compares the germicidal power of a disinfectant to that of phenol under specific conditions. A higher phenol coefficient indicates greater effectiveness.
Question 2: Which of the following is a Chlamydia-related condition?
- VRE
- Drug-Resistant Tuberculosis
- Herpes Simplex Type 2
- Puerperal Sepsis / Childbed Fever
- RSV
- Psittacosis (Correct answer)
Correct answer: Psittacosis
Psittacosis is a respiratory infection caused by the bacterium *Chlamydia psittaci*, which is primarily transmitted to humans from infected birds. While Chlamydia is commonly known for sexually transmitted infections, *Chlamydia psittaci* causes a distinct condition. The other options are caused by different types of pathogens or are not directly related to Chlamydia.
Question 3: Among the following, which one is not an STD?
- HSV
- Tularemia (Correct answer)
- Gonorrhea
- Hepatitis B
- HIV/AIDS
Correct answer: Tularemia
Tularemia is a bacterial disease caused by *Francisella tularensis*, typically transmitted through contact with infected animals (like rabbits, rodents) or insect bites (ticks, deer flies), or contaminated food/water. It is not primarily transmitted through sexual contact. The other options (HSV, Gonorrhea, Hepatitis B, HIV/AIDS) are all well-established sexually transmitted diseases.
Question 4: What compounds does the body produce in response to the intake of a foreign substance?
- Antibodies (Correct answer)
- Antigens
- Endotoxins
- Lysozymes
Correct answer: Antibodies
Antibodies are specialized proteins produced by the immune system in response to the presence of foreign substances, known as antigens. Their primary function is to identify and neutralize these foreign invaders, such as bacteria, viruses, or toxins. Antigens are the foreign substances themselves, while endotoxins are bacterial components and lysozymes are enzymes.
Question 5: Bacteria-produced toxins are only released when the bacteria's cells break down and die.
- Capsules
- Endotoxins (Correct answer)
- Exotoxins
- Endospores
Correct answer: Endotoxins
Endotoxins are lipopolysaccharide components of the outer membrane of Gram-negative bacteria. Unlike exotoxins, which are actively secreted by living bacteria, endotoxins are typically released only when the bacterial cells undergo lysis (break down and die). This release can trigger a strong immune response in the host.
Question 6: The kind of infection that spreads from one infected region to create new infected locations in the body is
- Acute
- Epidemic
- Focal (Correct answer)
- Local
Correct answer: Focal
A focal infection is one that starts in a specific, localized area of the body and then spreads to other distinct, non-contiguous areas, establishing new sites of infection. This differs from a local infection, which remains confined to one area, or a systemic infection, which is widespread throughout the body via the bloodstream or lymphatic system.
Question 7: Which of the following vectors transmits epidemic typhus, brought on by Rickettsia prowazekii and also known as petechial or putrid fever?
- Mosquitoes
- Flies
- Lice (Correct answer)
- Ticks
Correct answer: Lice
Epidemic typhus, caused by *Rickettsia prowazekii*, is primarily transmitted to humans through the body louse (*Pediculus humanus humanus*). The bacteria are present in the louse's feces, and infection occurs when the feces are rubbed into skin abrasions or mucous membranes, often after scratching an itchy louse bite.
