Correct Answers and Expert Explanation for Each
Question | Chamberlain
1. A 4-year-old is diagnosed with acute otitis media. Which antibiotic is considered
first-line therapy according to current guidelines?
A. Doxycycline
B. Ciprofloxacin
C. Amoxicillin
D. Azithromycin
Correct Answer: C
Expert Explanation: Amoxicillin is the first-line choice for pediatric acute otitis
media due to its effectiveness against common pathogens like Streptococcus
pneumoniae. High-dose amoxicillin is preferred to overcome potential penicillin
resistance in the community. It has a well-established safety profile in children
compared to other classes.
2. Which black box warning is associated with the use of fluoroquinolones like
Levofloxacin?
A. Acute renal failure
,B. Severe skin rash
C. Tendon rupture and tendonitis
D. Cardiac arrhythmias
Correct Answer: C
Expert Explanation: Fluoroquinolones carry a black box warning for increased risk
of tendonitis and tendon rupture, particularly involving the Achilles tendon. This
risk is higher in elderly patients, those taking corticosteroids, and transplant
recipients. Clinicians should advise patients to stop the medication and seek medical
help if they experience joint or tendon pain.
3. Which education point is most critical for a patient prescribed Rifampin for
tuberculosis?
A. It causes permanent hearing loss
B. It should be taken with a high-fat meal
C. It may cause orange discoloration of bodily fluids
D. It is safe to use with oral contraceptives without backup
Correct Answer: C
Expert Explanation: Rifampin frequently causes a harmless orange-red
discoloration of urine, sweat, saliva, and tears. Patients should be warned about this
,to prevent unnecessary alarm or concern. It can also permanently stain soft contact
lenses, so patients should be advised to wear glasses during treatment.
4. In the stepwise management of asthma, which medication is indicated for Step 2
treatment?
A. Oral corticosteroids
B. Low-dose inhaled corticosteroid (ICS)
C. Long-acting beta agonist (LABA) monotherapy
D. High-dose ICS plus LABA
Correct Answer: B
Expert Explanation: The preferred Step 2 treatment for asthma is a daily low-dose
inhaled corticosteroid (ICS) to manage underlying inflammation. This approach
helps reduce the frequency of symptoms and the risk of severe exacerbations. Using
a SABA as needed for rescue remains part of the plan alongside the maintenance ICS.
5. What is the primary mechanism of action for Macrolide antibiotics like
Azithromycin?
A. Inhibition of cell wall synthesis
B. Disruption of DNA gyrase
C. Binding to the 50S ribosomal subunit to inhibit protein synthesis
, D. Inhibition of folic acid synthesis
Correct Answer: C
Expert Explanation: Macrolides work by binding to the 50S subunit of the bacterial
ribosome, which prevents the translocation of peptide chains. This action is typically
bacteriostatic, meaning it inhibits the growth of bacteria rather than killing them
outright. They are commonly used for respiratory tract infections and certain
sexually transmitted infections.
6. A patient is prescribed Tetracycline for acne. What should the nurse practitioner
advise regarding administration?
A. Take with a large glass of milk
B. Avoid sun exposure and use sunscreen
C. Take an antacid immediately before the dose
D. This medication is safe during the third trimester of pregnancy
Correct Answer: B
Expert Explanation: Tetracyclines are known to cause photosensitivity, which can
lead to severe sunburn even with minimal sun exposure. Patients must be educated
to use sun protection and limit time outdoors. Additionally, these medications
should not be taken with dairy or antacids as they chelate with calcium and
minerals, reducing absorption.
