Laboratory testing has confirmed that a patient has chloroquine-resistant
malaria and the
... [Show More] patient's physician has prescribed quinine along with an
adjunctive drug. The nurse should question the physician's order if the
patient has a history of
Response
Feedback
:
Patients with cardiac arrhythmias may be at risk for developing
quinine-induced dysrhythmias and patients treated with quinine
have shown prolonged Q-T intervals. Low bone density,
diabetes, and COPD are not health problems that preclude the
use of quinine in the treatment of chloroquine-resistant malaria.
• Question 2
A patient with AIDS has developed a number of secondary infections in
1 out of 1 points
recent weeks, including Kaposi's sarcoma. As a result of this most recent
diagnosis, his care team has opted to begin treatment with interferon alfa-
2a. The nurse is aware that this drug will address the etiology of Kaposi
sarcoma by
Response
Feedback
:
Like other cytokines, interferon alfa-2a inhibits the growth of
tumor cells, prevents these cells from multiplying, and
modulates the host immune response to help protect the body
from tumor cells. This drug does not increase B-cell and T-cell
production, induce mutations, or increase the effects of
phagocytes and macrophages.
• Question 3
1 out of 1 points
A nurse has questioned why a patient's physician has prescribed a narrow-
spectrum antibiotic rather than a broad-spectrum drug in the treatment of
a patient's infection. Which of the following facts provides the best
rationale for the use of narrow-spectrum antibiotics whenever possible?
Response
Feedback
:
The benefit of a narrow-spectrum antimicrobial agent is that it
limits the potential for adverse effects, such as superinfection.
In a superinfection, an antibiotic suppresses all susceptible
microbes, including the body's natural flora, which may keep
other microbes in check. In the absence of these bacteria,
nonsusceptible microbes can proliferate. Narrow-spectrum
antibiotics do not lack demonstrated efficacy and they do not
necessarily require a shorter duration of treatment. All
antimicrobial drugs have the potential to impact subsequent
C&S testing. [Show Less]
