Question 1

Fill in the blanks to complete the following statements. 
___________ are tiny hair-like projections that help expel foreign particles from the respiratory tract.

Accepted Answer

Cilia

Question 2

Fill in the blanks to complete the following statements. 
Cells involved in the body's immune response utilize a process called ______________ to ingest microorganisms.

Accepted Answer

phagocytosis

Question 3

Select the best response to the question. Which of the following patients is at high risk of becoming ill from a pathogen with low virulence?

Accepted Answer

Patients with weakened immune systems, such as those undergoing chemotherapy, are at a higher risk of becoming ill from pathogens with low virulence because their immune system may not be able to mount a strong enough response to fight off the pathogen. The other options do not necessarily indicate a weakened immune system.

Question 4

Select the best response to the question. Which of the following is characteristic of a virus?

Accepted Answer

Viruses rely on the host cell's machinery to reproduce, as they cannot replicate on their own.

Question 5

Select the best response to the question. The nucleus of a cell is responsible for which of the following functions?

Accepted Answer

The nucleus contains the cell's genetic material and is responsible for controlling the cell's activities. It does not directly protect the integrity of the cell, maintain the shape of the cell, or produce and store energy.

Question 6

Match between columns
                        Premises: Being bitten by an animal infected with rabies.
Sitting close to a friend with the flu who is coughing frequently.
Touching the TV remote after an ill person has used it.
Eating meat that is contaminated with bacteria.

Accepted Answer

The Answer of airborne transmission and common vehicle transmission and is...

Question 7

Question 8

Most microorganisms in the body have the potential to cause illness.

Accepted Answer

While some microorganisms in the body can cause illness, the majority of them are harmless or even beneficial to our health, such as the bacteria in our gut that aid in digestion.

Question 9

Fill in the blanks to complete the following statements. 
The reproductive process through which a cell divides into two equal parts is ______________.

Accepted Answer

The answer of Fill in the blanks to complete the...

Question 10

Select the best response to the question. All of the following are functions of the cell membrane EXCEPT:

Accepted Answer

The cell membrane is responsible for protecting the cell from the environment, allowing nutrients into the cell, and allowing waste removal from the cell. However, maintaining cell shape is a function of the cytoskeleton, not the cell membrane.

Question 11

Select the best response to the question. You are reviewing a patient's sputum culture results that have tested positive for S taphylococcus epidermidis . How do you interpret these findings?

Accepted Answer

S. epidermidis is a common member of the normal flora of the skin and mucous membranes, including the respiratory tract. Its presence in sputum culture results does not necessarily indicate a respiratory infection. Rather, it likely means that the sputum sample was not collected in a sterile manner and picked up some of the normal flora present in the upper respiratory tract.

Question 12

Some bacteria form a capsule or slime layer around their cell wall in order to promote motility.

Accepted Answer

Bacteria may form a capsule or slime layer for a variety of reasons, such as protection from the immune system, dehydration, or attachment to surfaces. However, this layer is not typically used for promoting motility. Bacteria usually use flagella or cilia for movement.

Question 13

Select the best response to the question. What should be considered when a patient's urine culture result is positive for Escherichia coli ?

Accepted Answer

Escherichia coli is a normal flora bacterium found in the gastrointestinal tract. If a urine culture is positive for E. coli, it indicates that the bacteria from the rectum or anus may have migrated to the urethra and bladder. Therefore, treatment is needed to eliminate the infection.

Question 14

Select the best response to the question. Thoroughly cleaning a patient's room after discharge helps limit the spread of disease by:

Accepted Answer

Indirect contact transmission occurs when a person comes into contact with contaminated objects or surfaces. Thoroughly cleaning a patient's room after discharge helps to eliminate any potential pathogens left behind, reducing the risk of indirect contact transmission of disease. The other options (direct contact, airborne transmission, common vehicle transmission) are not directly related to the importance of cleaning a patient's room after discharge in limiting the spread of disease.

Question 15

Identify all answer choices that best complete the question. 
______________ include cells from humans, animals, plants, protozoa, fungi, and most algae.

Accepted Answer

The answer of Identify all answer choices that best complete...

Question 16

Identify all answer choices that best complete the question. Which of the following are found in prokaryotic cells?

Accepted Answer

Prokaryotic cells lack a nucleus, so option A is incorrect. However, they have a cell membrane, cell wall, and DNA, making options B, C, and D correct.

Question 17

Fill in the blanks to complete the following statements. 
The dilatation of blood vessels allowing the passage of fluid, antibodies, and WBCs into the infected body area is known as ______________.

Accepted Answer
