Question 1

If an ovarian tumor is cancerous, what organs need to be removed?

Accepted Answer

bilateral fallopian tubes and ovaries, uterus

Answer

If an ovarian tumor is cancerous, a comprehensive surgical approach is often required to ensure complete removal of the malignancy and prevent its spread. This typically involves a total hysterectomy (removal of the uterus) along with a bilateral salpingo-oophorectomy (removal of both fallopian tubes and ovaries). These organs are anatomically linked and potential sites for metastasis.

Question 2

What is the inner ear's spiral-conical structure called?

Accepted Answer

cochlea

Answer

The cochlea is the spiral-shaped, fluid-filled cavity in the inner ear that plays a crucial role in hearing. It contains the organ of Corti, which converts sound vibrations into nerve impulses. These impulses are then sent to the brain for interpretation, allowing us to perceive sound.

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

Commensalism is a type of symbiotic relationship between two organisms where one organism benefits, and the other organism is neither helped nor harmed. This interaction is distinct from mutualism, where both benefit, or parasitism, where one benefits at the expense of the other. An example is barnacles on whales.

Question 4

Informed consent is a fundamental ethical and legal principle in healthcare. It requires that a patient fully understands the nature of a proposed treatment, its potential risks, benefits, and alternatives before agreeing to it. This process ensures autonomous decision-making and protects patient rights.

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. Soaking instruments in a 2% glutaraldehyde solution for a specified duration, such as 20 minutes, is a recognized method for achieving high-level disinfection in healthcare settings. This is crucial for reprocessing heat-sensitive medical devices.
