C. Clindamycin
D. Doxcycline - ANSWER-C
Patients on clindamycin should promptly report any diarrhea to their health care provider
because clinadmycin can cause potentially fatal Clostridium difficile diarrhea. Diarrhea can be a
side effect of most antibiotics such as linezolid, doxycycline and minocycline but does nto have
the same risk as clindamycin for C. Diff
Which instructions should the nurse include in the plan of care for a patient receiving ferrous
sulfate therapy?
A. Iron does not absorb
B. Iron should only be taken at night
C. Iron compounds are not taken orally
D. Antacids should not be taken with iron - ANSWER-D

,Tetracyclines are bacteriostatic antibiotics; photosensitivity and severe sunburn are common
adverse effects. A full course of antibiotic must always be taken, Blood studies are not necessary
for therapetuic levels. Absorption decreases after ingestion of chelates such as calcium and
magnesium so doses should be given 2 hours before or 2 hours after ingestion of milk products
The nurse who is working in a pediatric unit administers tetracycline to a preschool-age child.
What is a potential side effect of the medication for this child?
A. Anabolic change
B. Cartilage damage
C. Discoloration of teeth
D. Suppression of growth - ANSWER-C
Tetracycline sometimes causes premature discoloration of teeth in children, and it is not
supposed to be used in growing children. Cartilage damage is caused by quinolone antibiotics.

A. Leukopenia commonly occurs
B. It is potentially fatal condition
C. Patients usually experience abdominal pain

A. They can cause ototoxicity
B. They can cause kernicterus
C. The can cause yeast infections
D. They can cause discoloration of teeth - ANSWER-B
Sulfonamide usage is avoided, if possible, for infants younger than 2 months of age because it can
cause a potentially fatal condition called kernicterus. Ototoxicity and discoloration of teeth is not
a common risk for sulfonamides. Yeast infections can occur with most antibiotics, and use of an
antibiotic is not avoided for this common side effect
Which statements about Stevens-Johnson syndrome should the nurse identify as true? Select all
that apply.
A. Toxemia is associated with Steven-Johnson syndrome
B. Patients with Stevens-Johnson syndrome usually are hypothermic
C. Lesions of the mucous membranes are a characteristic of Steven Johnson syndrome
D. Short-acting sulfonamides do not induce
E. Stevens-Johnson syndrome. Patients with Stevens-Johnson syndrome have a mortality
rate of about 25% - ANSWER-A, C, E
Stevens-Johnson syndrome is associated with toxemia, has a mortality rate of about 25% and is
characterized by skin lesions and lesions on the mucous membranes. Short-acting sulfonamides
