A child comes to the clinic for evaluation of skin lesions and is diagnosed with impetigo. Which of the following medications would the nurse anticipate the physician might prescribe?
Tetracyline
Penicillin
Metronidazole
Lindane
The Correct Answer is B
A. Tetracycline:
Tetracycline antibiotics, such as doxycycline or minocycline, can be effective against the bacteria that cause impetigo. However, their use in children, especially younger ones, might be limited due to concerns about potential effects on developing teeth and bones. Therefore, they are not the first-line choice for pediatric impetigo.
B. Penicillin:
Penicillin or other antibiotics in the penicillin family, such as dicloxacillin or amoxicillin, are commonly used to treat impetigo caused by Streptococcus pyogenes. Penicillin-based antibiotics are effective against certain strains of the bacteria responsible for impetigo. They are often a preferred choice for pediatric impetigo.
C. Metronidazole:
Metronidazole is an antibiotic with activity against anaerobic bacteria and certain parasites. However, it is not typically used to treat impetigo caused by Staphylococcus aureus or Streptococcus pyogenes.
D. Lindane:
Lindane is an anti-parasitic medication used for conditions like scabies or lice. It is not effective against the bacteria that cause impetigo. Lindane is not an appropriate treatment for impetigo, and its use is limited due to potential neurotoxicity.

Correct Answer is C
Explanation
A. Rubella:
Rubella, also known as German measles, typically presents with a rash that starts on the face and spreads to the trunk and limbs. It does not cause Koplik spots, the small red spots with a blue-white center mentioned in the scenario.
B. Varicella:
Varicella, or chickenpox, is characterized by an itchy rash that progresses to fluid-filled vesicles. It does not typically involve Koplik spots, and the scenario doesn't describe a vesicular rash.
C. Rubeola (Measles):
Rubeola, or measles, presents with symptoms such as high fever, cough, rhinitis, and conjunctivitis. The characteristic Koplik spots, small red spots with a blue-white center, often appear on the buccal mucosa. This matches the description in the scenario.
D. Infectious Mononucleosis:
Infectious Mononucleosis is characterized by symptoms like fever, sore throat, and swollen lymph nodes. It does not present with the specific buccal membrane spots seen in measles, and the scenario does not mention other typical signs of infectious mononucleosis.
