Question 1:
Which type of bacteria forms in chains?
A. Staphylococci
B. Clostridium difficile
C. Diplococci
D. Streptococci
Question 2:
MRSA can be spread through, which of the following?
A. breathing infected droplets.
B. contact with infected feces, blood, or urine.
C. contaminated antibiotics.
D. direct contact with a patient.
Question 1: D. Streptococci
Question 2: D. direct contact with a patient.
Question 1: The type of bacteria that forms in chains is D. Streptococci.
Question 2: MRSA can be spread through various means, including D. direct contact with a patient.
To answer question 1, we can identify the type of bacteria that forms chains by their name. Let's look at the options:
A. Staphylococci: Staphylococci bacteria form clusters or groups, not chains.
B. Clostridium difficile: Clostridium difficile bacteria do not typically form chains.
C. Diplococci: Diplococci bacteria form pairs or clusters, not chains.
D. Streptococci: Streptococci bacteria are known to form chains.
Therefore, the correct answer to question 1 is D. Streptococci.
Now, let's move on to question 2. We need to identify how MRSA (Methicillin-resistant Staphylococcus aureus) can spread.
A. Breathing infected droplets: MRSA is primarily transmitted through direct contact, so breathing infected droplets is not a common mode of transmission.
B. Contact with infected feces, blood, or urine: This is a possible mode of transmission for MRSA. Contact with contaminated bodily fluids can spread the bacteria.
C. Contaminated antibiotics: Contaminated antibiotics are not a typical mode of transmission for MRSA. It is primarily spread through person-to-person contact.
D. Direct contact with a patient: This is the most common mode of transmission for MRSA. Direct contact with an infected person's skin, wounds, or personal items can spread the bacteria.
Therefore, the correct answer to question 2 is D. Direct contact with a patient.
