Section I — Fungal and Viral Pharmacotherapy
Question 1
A patient is receiving amphotericin B for a serious systemic
fungal infection. Which laboratory parameter is particularly
important to monitor during therapy?
A. Hemoglobin A1c
B. Serum creatinine and renal function
C. Thyroid-stimulating hormone
D. Serum amylase
Correct Answer: B. Serum creatinine and renal function
Rationale: Amphotericin B is an effective systemic antifungal but
is associated with significant nephrotoxicity. The drug can
decrease renal function and cause electrolyte abnormalities,
particularly hypokalemia and hypomagnesemia. Monitoring
,serum creatinine, BUN, potassium, magnesium, and overall
renal status helps identify toxicity early. Patients receiving
conventional amphotericin B generally require particularly close
renal monitoring. Lipid formulations may reduce nephrotoxicity
compared with conventional formulations but do not eliminate
the need for monitoring.
Question 2
Which intervention can help reduce the risk of amphotericin B–
associated nephrotoxicity?
A. Restricting all oral fluids
B. Administering appropriate IV fluid hydration
C. Administering potassium-wasting diuretics
D. Giving the medication with grapefruit juice
Correct Answer: B. Administering appropriate IV fluid
hydration
Rationale: Adequate hydration before and during amphotericin
B therapy can help preserve renal perfusion and reduce
nephrotoxicity. Renal function and electrolytes should still be
monitored because hydration does not completely prevent
kidney injury. Potassium and magnesium depletion can occur
and may require replacement. Fluid management should be
,individualized according to the patient's cardiac, renal, and
overall clinical status.
Question 3
A patient prescribed itraconazole asks why the provider is
concerned about other medications the patient takes. What is
the best explanation?
A. Itraconazole has no clinically important drug interactions.
B. Itraconazole can inhibit CYP-mediated metabolism and
increase concentrations of certain medications.
C. Itraconazole universally decreases absorption of all
medications.
D. Itraconazole causes all medications to become inactive.
Correct Answer: B. Itraconazole can inhibit CYP-mediated
metabolism and increase concentrations of certain
medications.
Rationale: Itraconazole is associated with clinically important
drug interactions because it inhibits CYP3A4 and can increase
concentrations of medications metabolized through this
pathway. This can potentially increase toxicity from drugs such
as certain antiarrhythmics, statins, benzodiazepines, and other
agents. A complete medication reconciliation is therefore
essential before itraconazole is prescribed. The clinician should
, assess prescription medications, over-the-counter products, and
supplements.
Question 4
Which medication is an echinocandin used for treatment of
certain invasive Candida infections?
A. Caspofungin
B. Acyclovir
C. Oseltamivir
D. Valacyclovir
Correct Answer: A. Caspofungin
Rationale: Caspofungin is an echinocandin antifungal.
Echinocandins inhibit beta-(1,3)-D-glucan synthesis, an
important component of the fungal cell wall. Caspofungin is
used for several invasive Candida infections and has activity
against Aspergillus species as well. Acyclovir and valacyclovir
are antiviral agents, whereas oseltamivir is primarily used for
influenza.
Question 5
Which adverse effect should the clinician monitor for in a
patient receiving caspofungin?
