Ascorers
, NR566 Week 1 Exam: Advanced Pharmacology Fundamentals
Instructions: Choose the best answer for each question. Questions are based on
content from Week 1 readings and accompanying study materials.
1. A 72-year-old patient with a history of myasthenia gravis and a recurrent
urinary tract infection is prescribed ciprofloxacin. Prior to dispensing the
medication, the provider reviews the black box warning for fluoroquinolones.
What information is most critical to discuss with this patient?
A. The risk of tendon rupture and exacerbation of muscle weakness.
B. The need to monitor blood glucose levels closely.
C. The importance of taking the medication with antacids to prevent GI upset.
D. The potential for a permanent, disabling decrease in renal function.
The Correct Answer Is A. Fluoroquinolones, including ciprofloxacin and
levofloxacin, carry a black box warning regarding an increased risk of tendinitis
and tendon rupture. This risk is heightened in older adults and those with
conditions like myasthenia gravis, as the drug class can also exacerbate muscle
weakness. Patients must be advised to stop the medication and seek immediate care
if they experience tendon pain or swelling.

2. A 6-year-old child is diagnosed with community-acquired pneumonia
(CAP). The prescriber needs to select an antibiotic that is effective against the
Ascorers
,most likely pathogens, including Mycoplasma pneumoniae. Which class of
antibiotics is considered the treatment of choice in this pediatric patient?
A. Tetracyclines (doxycycline)
B. Fluoroquinolones (levofloxacin)
C. Macrolides (azithromycin)
D. Aminoglycosides (gentamicin)
The Correct Answer Is C. Macrolides, such as azithromycin, are the preferred
treatment for Mycoplasma pneumoniae, a common atypical pathogen causing CAP
in children. They are also safe and effective for this age group. While doxycycline
is effective, it is not the first choice in young children due to dental staining risks.
Fluoroquinolones are generally avoided in children due to concern for tendon
injury.
...
3. A 30-year-old pregnant patient in her third trimester presents with a
bacterial infection. The provider considers prescribing a course of penicillins.
According to lifespan considerations, what is the current understanding of
penicillin use during pregnancy?
A. Avoid in pregnancy as it can cause fetal harm, especially in the first trimester.
B. Evidence suggests no second or third trimester fetal risk, making it a relatively
safe option.
C. Use is contraindicated due to the risk of permanent tooth discoloration in the
fetus.
D. Data is lacking, so another class of antibiotics with more safety data should be
chosen.
Ascorers
, The Correct Answer Is B. Penicillins are among the safer antibiotics to use
during pregnancy. The file specifically notes that for pregnant women, "evidence
suggests no second or third trimester fetal risk." While amoxicillin has the most
data, penicillins are generally preferred over other classes with known teratogenic
risks (like tetracyclines) when clinically appropriate.
...
4. A patient is diagnosed with a C. difficile infection (CDIff). This is their first
episode, and the presentation is classified as severe. Based on current
treatment guidelines highlighted in the material, what is an appropriate initial
treatment regimen?
A. Metronidazole 500mg PO TID x 10-14 days
B. Oral vancomycin 125mg PO QID or fidaxomicin 200mg PO BID for 10 days
C. A tapered and pulsed regimen of oral vancomycin over several weeks
D. Intravenous metronidazole and oral vancomycin
The Correct Answer Is B. For an initial episode of severe CDIff, the
recommended treatments are either oral vancomycin (125mg four times daily) or
fidaxomicin (200mg twice daily) for 10 days. A tapered/pulsed regimen of
vancomycin is reserved for treating a first recurrence. Metronidazole is no longer a
first-line agent for severe cases.
...
5. An infant less than 2 months old presents with a fever. The prescriber
considers antibiotic therapy but recalls that certain antibiotic classes are
contraindicated in this age group due to the risk of kernicterus. Which
antibiotic class should be avoided?
