Which statement is true regarding narrow spectrum antibiotics?

They are effective against gram-positive bacteria only.

They are effective against gram-negative bacteria only.

They are effective against one type of organism.

They are effective against a few types of organisms.

Answer and Explanation

The Correct Answer is D

They are effective against a few types of organisms. Narrow spectrum antibiotics are antibiotics that work against a limited range of bacteria, usually either gram-positive or gram-negative. They are more specific and less likely to cause resistance or disrupt the normal flora.

Choice A) They are effective against gram-positive bacteria only. This is not true because some narrow spectrum antibiotics can also target gram-negative bacteria, such as aminoglycosides.

Choice B) They are effective against gram-negative bacteria only. This is not true because some narrow spectrum antibiotics can also target gram-positive bacteria, such as vancomycin.

Choice C) They are effective against one type of organism. This is too restrictive because narrow spectrum antibiotics can work against more than one type of organism, such as penicillins that target both streptococci and staphylococci.

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.

A. First-generation B. Second-generation C. Third-generation D. Fourth-generation.

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.
