PN 125 PHARMACOLOGY EXAM 2 QUESTIONSWITH ANSWERS
Anti-infective therapeutic effects - ANSWER The goal is to interfere with the
normal function of the invading organism to prevent it from reproducing and to
cause cell death without affecting host cells
What do anti-infectives do? - ANSWER The goal of antiinfective therapy is the
reduction of the invading organisms to a point at which the human immune
response can take care of the infection
What is Chlamydia Trachomatis and which antibiotic treats it? - ANSWER
bacterium is most commonly spread through vaginal, oral and anal sex. It's also
possible for pregnant women to spread chlamydia to their children during delivery,
causing pneumonia or a serious eye infection in the newborn
-doxycycline and azithromycin
Education about anti-infectives, teaching patients - ANSWER This drug is
prescribed for treating the particular infection that you have now. Do not use this
drug to treat other infections.
This drug needs to be taken as prescribed—for the correct number of times each
day and for the full number of days. Do not stop taking the drug if you start feeling
better. You need to take the drug for the full number of treatment days to ensure
that the infection has been destroyed.
Merrem drug-related actions - ANSWER an IV antibiotic from the carbapenem
class of antibiotics, inhibits the synthesis of bacterial cell walls in susceptible
bacteria. It is used to treat intra-abdominal infections and some cases of meningitis
caused by susceptible bacteria
Penicillin mechanism of action - ANSWER Penicillin kills bacteria through
binding of the beta-lactam ring to DD-transpeptidase, inhibiting its cross-linking
activity and preventing new cell wall formation
, Why do we culture wounds? - ANSWER To ensure the right drug of choice for
patient
Why do we use Bactrim for UTI's? - ANSWER Because of the emergence of
resistant bacterial strains and the development of newer antibiotics, the sulfa drugs
are no longer used much. However, they remain an inexpensive and effective
treatment for UTIs and trachoma, especially in developing countries and when cost
is an issue
Gram Negative/ Aminoglycosides priorities - ANSWER Ensure that the patient
receives a full course of aminoglycoside as prescribed, divided around the clock, to
increase effectiveness and decrease the risk for development of resistant strains of
bacteria. Monitor the patient regularly for signs of nephrotoxicity, neurotoxicity,
and bone marrow suppression to effectively arrange for discontinuation of drug or
decreased dose, as appropriate, if any of these toxicities occurs
Antibiotics that are selectively toxic? - ANSWER -Vancomycin's use is reserved
for special situations as it may be highly toxic and can cause renal failure,
ototoxicity, and superinfections.
-selective toxicity, which is the ability to affect certain proteins or enzyme systems
used only by the infecting organism but not by human cells. Because all living cells
are somewhat similar, no anti-infective drug has yet been developed that does not
affect the host
Education for a patient taking Rifampin for TB - ANSWER -Try to drink a lot of
fluids and to maintain nutrition (very important) even though nausea, vomiting, and
diarrhoea may occur.
-Use barrier contraceptives, and understand that hormonal contraceptives may not
be effective if antimycobacterial are being used.
-Understand that normally some of these drugs impart an orange stain to body
fluids. If this occurs, the fluids may stain clothing and tears may stain contact
lenses.
-Report difficulty breathing, hallucinations, numbness and tingling, worsening of
condition, fever and chills, or changes in color of urine or stool
Nursing Diagnosis for Patient Education - ANSWER
