In pharmaceutical companies, Sterilization is an important step for quality assurance and approval of pharmaceutical products. Based on this concept, answer the following questions.
Heat sensitive liquids need special methods for sterilization. Explain the methods applied in details.
In sterilization, which among the supplies, instruments, glassware, etc. under the list of materials can be sterilized using either or both equipment below? List them down under the category: a) For “autoclaving” only, B) For Dry heat oven sterilization ,And C) Can be sterilized with either.
Materials:
200-ml Erlenmeyer flask Stove
500-ml Erlenmeyer flask Autoclave
10-mL graduated cylinder Analytical balance
100-ml graduated cylinder pH meter
Spatula Stirring rod
100-mL beaker Test tubes
Distilled water Petri dish
Stirring rod Alcohol lamp
Glass dropper
These are examples of the 5 rules of asepsis, except:
1. Any item used for patient care or that is visibly soiled must be considered "dirty"
and "contaminated"
2. If the item has been cleaned with a detergent disinfectant, it is both clean and
decontaminated
3. Sterile items are devices processed by steam, dry heat, ethylene oxide or other
sterilization method to kill most organisms
4. Dirty, clean and sterile items must be separated at all times

- Imagine that you work at the medical examiner’s office for a major metropolitan city. As Chief Medical Officer, you investigate suspicious deaths and provide toxicology services for the county. Unfortunately, it’s been a busy week. In the past five days, seven people have died, all with similar symptoms. It is your job to examine the data and determine the cause of death for these victims.The first was a 12-year-old girl. Her parents said that she was awake in the middle of the night complaining of a stuffy nose and sore throat. They gave her an extra strength Tylenol and sent her back to bed. At 7am the next morning,the parents discovered that the girl had collapsed on the bathroom floor. An ambulance rushed the girl to a nearby hospital, where she was pronounced dead.That same day, paramedics found the second victim unconscious on his kitchen floor after what they thought was an apparent heart attack. Sadly, the victim’s brother and fiancée also collapsed later that night while the…arrow_forwardIn sterilization, which among the supplies, instruments, glassware, etc. under the list of materials can be sterilized using either or both equipment below?
