1.
A 67-year-old hospitalized patient with septic shock has suspected
methicillin-resistant Staphylococcus aureus (MRSA) bacteremia. Blood
cultures are pending. The patient has received adequate crystalloid
resuscitation and requires norepinephrine. Which antimicrobial regimen
is most appropriate for initial empiric therapy?
A. Cefazolin monotherapy
B. Vancomycin plus an appropriate broad-spectrum gram-negative agent
C. Azithromycin monotherapy
D. Metronidazole monotherapy
Answer: B. Vancomycin plus an appropriate broad-spectrum gram-
negative agent
Rationale: Septic shock with suspected healthcare-associated infection
requires immediate empiric antimicrobial therapy covering likely
resistant gram-positive and gram-negative organisms. Vancomycin
provides MRSA coverage, while an agent such as cefepime,
piperacillin-tazobactam, or meropenem may provide appropriate gram-
negative coverage depending on the patient's history, local
antibiogram, allergy profile, renal function, and infection source.
Cefazolin alone does not reliably cover MRSA or resistant gram-
negative pathogens.

,2.
A patient receiving vancomycin for MRSA bacteremia has a creatinine
clearance that decreases substantially over 48 hours. Which
pharmacokinetic parameter is most directly affected by declining renal
function?
A. Bioavailability
B. Volume of distribution only
C. Clearance
D. Protein binding only
Answer: C. Clearance
Rationale: Vancomycin is predominantly eliminated renally. Declining
renal function decreases systemic clearance, resulting in increased
exposure and a prolonged half-life. Dosing and monitoring should
therefore be adjusted according to renal function and an appropriate
exposure target, commonly using AUC-guided monitoring for serious
MRSA infections.
3.
Which pharmacodynamic target is generally associated with efficacy of
vancomycin against serious MRSA infections?
A. Cmax/MIC of 2
B. AUC/MIC
C. Time below MIC
D. Urinary concentration/MIC only
Answer: B. AUC/MIC
Rationale: Vancomycin efficacy is best associated with the ratio of the
24-hour area under the concentration-time curve to the organism's
2
,MIC. For serious MRSA infections, contemporary therapeutic drug
monitoring commonly targets an AUC/MIC range of approximately
400–600 when the MIC is assumed to be 1 mg/L. Excessive exposure
increases nephrotoxicity risk without necessarily improving efficacy.
4.
A patient with suspected bacterial meningitis is empirically treated
before the causative organism is identified. Which antimicrobial
combination is most appropriate for an immunocompetent adult aged 68
years?
A. Ceftriaxone plus vancomycin plus ampicillin
B. Azithromycin plus metronidazole
C. Cefazolin plus doxycycline
D. Ampicillin alone
Answer: A. Ceftriaxone plus vancomycin plus ampicillin
Rationale: In older adults, empiric meningitis therapy must include
coverage for penicillin-resistant pneumococci and Listeria
monocytogenes. Vancomycin plus a third-generation cephalosporin
provides broad coverage for common bacterial pathogens, while
ampicillin provides Listeria coverage.
5.
A patient with HIV is newly diagnosed with cryptococcal meningitis.
Which induction regimen is generally preferred for severe cryptococcal
meningitis?
A. Fluconazole alone
B. Liposomal amphotericin B plus flucytosine
3
, C. Itraconazole alone
D. Voriconazole alone
Answer: B. Liposomal amphotericin B plus flucytosine
Rationale: Induction therapy for cryptococcal meningitis generally
requires a fungicidal regimen. Liposomal amphotericin B plus
flucytosine is a highly effective induction regimen. Fluconazole alone
is inadequate for initial treatment of severe cryptococcal meningitis
because of slower fungal clearance and poorer outcomes.
6.
A patient taking rifampin for tuberculosis develops reduced
concentrations of a coadministered medication. What best explains this
interaction?
A. Rifampin inhibits CYP3A4
B. Rifampin induces multiple metabolic enzymes and transporters
C. Rifampin inhibits renal secretion
D. Rifampin blocks intestinal absorption of all drugs
Answer: B. Rifampin induces multiple metabolic enzymes and
transporters
Rationale: Rifampin is a potent inducer of several drug-metabolizing
enzymes and transport proteins. This can substantially lower
concentrations of many drugs, including selected antiretrovirals,
anticoagulants, immunosuppressants, and hormonal contraceptives.
Medication reconciliation is therefore critical whenever rifampin is
initiated or discontinued.
