that penicillins:
a. disinhibit transpeptidases.
b. disrupt bacterial cell wall synthesis.
c. inhibit autolysins.
d. inhibit host cell wall function.
b. disrupt bacterial cell wall synthesis.
*Penicillins (PCNs) are antibiotics that work by disrupting bacterial cell wall synthesis.
2.A patient is about to receive penicillin G for an infection that is highly sensitive to this
drug. While obtaining the patient's medication history, the nurse learns that the patient

a. Ask the provider to order a cephalosporin.
b. Reassure the patient that allergic responses diminish over time.
c. Request an order for a skin test to assess the current risk.
d. Suggest using a desensitization schedule to administer the drug.
c. Request an order for a skin test to assess the current risk.
*It helps determine whether a patient has developed an allergic sensitivity to penicillin over
time or if the previous reaction was an isolated incident.
,3.A patient with no known drug allergies is receiving amoxicillin (Amoxil) PO twice daily.
Twenty minutes after being given a dose, the patient complains of shortness of breath.
The patient's blood pressure is 100/58 mm Hg. What will the nurse do?
a.Contact the provider and prepare to administer epinephrine.
b. Notify the provider if the patient develops a rash.
c. Request an order for a skin test to evaluate possible PCN allergy.
d. Withhold the next dose until symptoms subside.
a. Contact the provider and prepare to administer epinephrine.
*Shortness of breath and hypotension are symptoms of anaphylaxis especially after an
antibiotic with high risk for allergic reaction
4.A patient with an infection caused by Pseudomonas aeruginosa is being treated with
piperacillin. The nurse providing care reviews the patient's laboratory reports and notes
that the patient's blood urea nitrogen and serum creatinine levels are elevated. The nurse
will contact the provider to discuss:
a. adding an aminoglycoside.
b. changing to penicillin G.
c. reducing the dose of piperacillin. d. ordering nafcillin.
c. reducing the dose of piperacillin.
*minimizing the risk of nephrotoxicity
, 5.A patient recently began receiving clindamycin (Cleocin) to treat an infection. After 8
days of treatment, the patient reports having 10 to 15 watery stools per day. What will the
nurse tell this patient?
a. The provider may increase the clindamycin dose to treat this infection.
b. This is a known side effect of clindamycin, and the patient should consume extra fluids.
c. The patient should stop taking the clindamycin now and contact the provider
immediately.d. The patient should try taking Lomotil or a bulk laxative to minimize the
diarrheal symptoms.
c. The patient should stop taking the clindamycin now and contact the provider
*could indicate pseudomembranous colitis
6.Which side effect of clindamycin (Cleocin) causes the most concern and may warrant
discontinuation of the drug?
a. Diarrhea
b. Headache
c. Nausea
d. Vomiting
a. Diarrhea
*could indicate pseudomembranous colitis
7.A patient develops Clostridium difficile-associated diarrhea (CDAD). Which antibiotic is
recommended for treating this infection?
a. Chloramphenicol
b. Clindamycin (Cleocin)
c. Linezolid (Zyvox)
d. Vancomycin
d. Vancomycin
*Vancomycin is often used as the first-line treatment for CDAD.
, 8.A pregnant patient is treated with trimethoprim/sulfamethoxazole (TMP/SMZ) (Bactrim)
for a urinary tract infection at 34 weeks' gestation. A week later, the woman delivers her
infant prematurely. The nurse will expect to monitor the infant for:
a. birth defects.
b. hypoglycemia.
c. rash.
d. scleral jaundice.
b. hypoglycemia.
*at an increased risk of kernicterus (bilirubin staining of the basal ganglia of the brain) in
newborns and an increased risk of hypoglycemia.
9.A patient who is taking immunosuppressants develops a urinary tract infection. The
causative organism is sensitive to sulfonamides and to another, more expensive antibiotic.
The prescriber orders the more expensive antibiotic. The nursing student assigned to this
patient asks the nurse why the more expensive antibiotic is being used. Which response by
the nurse is correct?
a. "Immunosuppressed patients are folate deficient."
b. "Patients who are immunosuppressed are more likely to develop resistance."
c. "Sulfonamides are bacteriostatic and depend on host immunity to work."
d. "Sulfonamides intensify the effects of immunosuppression."
c. "Sulfonamides are bacteriostatic and depend on host immunity to work."
*the efficacy of bacteriostatic agents like sulfonamides may be diminished in
immunosuppressive patients
