Which term is used to describe an agent that inhibits bacterial growth but does not kill bacteria?

Bactericidal

Bacteriostatic

Bacteriolytic

Bacteriophage.

Answer and Explanation

The Correct Answer is B

A bacteriostatic agent is an agent that inhibits the growth or reproduction of bacteria, but does not kill them.

This means that the bacteria are still alive, but they cannot multiply or cause infection.

Choice A) Bactericidal is wrong because a bactericidal agent is an agent with the capability to kill bacteria.

This means that the bacteria are no longer alive or viable.

Choice C) Bacteriolytic is wrong because a bacteriolytic agent is an agent that causes the lysis or rupture of bacterial cells.

This means that the bacteria are destroyed and their contents are released.

Choice D) Bacteriophage is wrong because a bacteriophage is not an agent, but a type of virus that infects and replicates within bacteria.

This means that the bacteriophage uses the bacteria as hosts and may kill them or not depending on the type of infection.

Correct Answer is C

Explanation

Ceftriaxone belongs to the third-generation of cephalosporins.Third-generation cephalosporins have greater activity than the second-generation cephalosporins against certain gram-negative bacteria, such as Streptococcus pneumoniae.They are also more resistant to beta-lactamases, enzymes that can inactivate some cephalosporins.

Choice A is wrong because first-generation cephalosporins have less activity against gram-negative bacteria and are more susceptible to beta-lactamases.

Choice B is wrong because second-generation cephalosporins have less activity against Streptococcus pneumoniae than third-generation cephalosporins, and are also less resistant to beta-lactamases.

Choice D is wrong because fourth-generation cephalosporins have a broader spectrum of activity against gram-negative bacteria, including some that are resistant to third-generation cephalosporins, but they are not more effective against Streptococcus pneumoniae.

A. Jaundice B. Vision changes C. Hearing loss D. Orange-colored urine E. Numbness in the hands or feet.

Correct Answer is ["A","B","E"]

Explanation

Jaundice, vision changes and numbness in the hands or feet are possible adverse effects of the drugs used to treat tuberculosis.The nurse should instruct the client to report these signs or symptoms as they may indicate liver damage, optic neuritis or peripheral neuropathy respectively.

Choice C is wrong because hearing loss is not a common side effect of these drugs.Hearing loss may be caused by other drugs such as aminoglycosides.

Choice D is wrong because orange-colored urine is a harmless side effect of rifampin and does not need to be reported.

The nurse should inform the client about this expected change and reassure them that it is not harmful.

The normal ranges for liver function tests are:

• AST: 10-40 U/L

• ALT: 7-56 U/L

• ALP: 45-115 U/L

• Bilirubin: 0.1-1.2 mg/dL

The normal range for visual acuity is 20/20.

The normal range for sensation is intact and symmetrical in all extremities.
