Question 3

What is the name of the interaction between two organisms that coexist in the same space but where one benefits while the other is unaffected?

Accepted Answer

Commensalism

Answer

The correct answer is Commensalism. This term describes a symbiotic relationship where one organism benefits from the interaction, while the other organism is neither significantly harmed nor helped. Unlike mutualism (where both benefit) or parasitism (where one benefits at the expense of the other), commensalism is characterized by a neutral effect on one of the participants.

Question 4

Accepted Answer

Informed consent

Answer

The correct answer is Informed Consent. This is a crucial ethical and legal principle in healthcare, requiring that a patient or their legal guardian grant permission for a medical procedure or treatment only after being fully informed of all relevant facts. This includes understanding the nature of the treatment, its potential benefits, risks, alternatives, and the consequences of refusing treatment, ensuring the decision is made with full awareness.

Question 5

Which one of the following constitutes a high-level disinfection technique?

Accepted Answer

2% glutaraldehyde for 20 minutes

Answer

High-level disinfection is a process that kills all microorganisms except for a high number of bacterial spores. Using 2% glutaraldehyde for 20 minutes is a recognized method for achieving high-level disinfection, as glutaraldehyde is a potent chemical sterilant and disinfectant effective against a broad spectrum of microbes. This method is commonly used for heat-sensitive medical devices that cannot be sterilized by heat.
