Deck 48: Antibiotics Affecting the Bacterial Cell Wall

Question 1

1)First
2)Second
3)Third
4)Fourth

Answer 1

4

Question 2

Which patient should be monitored closely while receiving penicillin G? A patient who:
1)Has diabetes and is on dialysis.
2)Is postop from corneal transplant.
3)Has osteomyelitis and will need IV medication for several months.
4)Experienced a myocardial infarction two days ago and now has a fever of 102^oF.

Answer 2

1

Question 3

Which statement best describes the bacterial cell wall?
1)It is semipermeable.
2)It is a rigid structure.
3)It is single-layered.
4)It is comprised of lipids.

Answer 3

2

Question 4

Two members of the cephalosporin group that interfere with vitamin K metabolism and increase the risk of bleeding include:
1)Cefoperazone and cefriaxone.
2)Cefoperazone and cefotetan.
3)Cefazolin and cefriaxone.
4)Cefazolin and cefotetan.

Question 5

Two members of the cephalosporin group not secreted by the kidneys include:
1)Cefoperazone and cefriaxone.
2)Cefoperazone and cefotetan.
3)Cefazolin and cefriaxone.
4)Cefazolin and cefotetan.

Question 6

Augmentin is considered a combination penicillin because it contains the additive clavulanate.Clavulanate is a(n):
1)Secondary antibiotic.
2)Anti-inflammatory to prevent allergic response.
3)Beta-lactamase inhibitor which prevents excretion of penicillin.
4)Antiviral to prevent superinfection.

Question 7

A side effect unique to the carbapenem antibiotics the development of:
1)Renal calculi.
2)Pseudomembranous enterocolitis.
3)Stevens-Johnson syndrome.
4)Red man syndrome.

Question 8

A patient is seen in the Emergency Department, and will be dismissed with a diagnosis of infection and a prescription for penicillin and the drug probenecid.The patient questions the nurse about the drug probenecid.Which statement by the nurse is correct regarding probenecid?
1)Probenecid is a secondary antibiotic.
2)Probenecid will prevent an allergic response.
3)Probenecid will increase the effectiveness of penicillin.
4)Probenecid prevents diarrhea often associated with penicillin.

Question 9

Bacteria enzymes participate in the development of the bacteria cell wall.How does penicillin target these enzymes? It interferes with:
1)The bacteria's ability to develop cross-links to strengthen its wall.
2)Bacterial protein synthesis.
3)The channels in the cells' internal structure.
4)Bacterial DNA.

Question 10

Two members of the cephalosporin group that exert a disulfiram-like reaction and should not be taken concurrently with alcohol include:
1)Cefoperazone and cefriaxone.
2)Cefoperazone and cefotetan.
3)Cefazolin and cefriaxone.
4)Cefazolin and cefotetan.

Question 11

Penicillin's antibacterial activity is due to its:
1)Beta-lactam ring that terminates construction of the cell wall.
2)Interference with cellular cytoplasm.
3)Alteration of bacterial DNA in the cell wall.
4)Interruption of bacterial protein synthesis.

Question 12

Extended-spectrum penicillins such as carbenicillin differ from other classes because they are effective against which microbe?
1)Pseudomonas
2)Staphylococcus
3)Streptococcus
4)Herpes simplex

Question 13

Which instruction should take priority in regard to patient teaching for any antibiotic therapy?
1)Maintain an adequate fluid intake.
2)Report symptoms of secondary infection, such as vaginal yeast infections.
3)The full course of prescribed drug therapy must be completed.
4)Maintain adequate food intake.
