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.

Related Questions
Correct Answer is B
Explanation
A. Inability to make audible voice sounds:
This symptom is more indicative of conditions affecting the vocal cords or larynx, such as laryngitis. Tonsillitis primarily involves inflammation of the tonsils and may not directly impact the ability to make audible voice sounds.
B. Erythema of the pharynx:
Erythema (redness) of the pharynx is a common manifestation of tonsillitis. Inflammation of the tonsils and surrounding areas can lead to redness and swelling in the throat.
C. Bark-like cough:
A bark-like cough is often associated with croup, which involves inflammation of the larynx and trachea, not the tonsils. It is a distinct condition from tonsillitis.
D. Hoarseness:
Hoarseness can be a symptom of various conditions affecting the vocal cords or larynx, but it is not a typical manifestation of tonsillitis. Tonsillitis is more commonly associated with sore throat, difficulty swallowing, and erythema of the pharynx.
Correct Answer is B
Explanation
A. Sore throat:
A sore throat is a common symptom of various respiratory tract infections, including acute epiglottitis. However, examining the throat with a tongue depressor is unlikely to directly precipitate a sore throat in this context.
B. Complete obstruction:
Examining the child's throat with a tongue depressor in acute epiglottitis can potentially trigger spasm or swelling of the already inflamed epiglottis, leading to a rapid and complete obstruction of the airway. This is a critical concern and is why healthcare providers approach suspected cases of epiglottitis with great caution.
C. Inspiratory stridor:
Inspiratory stridor (high-pitched sound during inhalation) is a common symptom of upper airway obstruction, including in conditions like acute epiglottitis. It may be present without manipulation, but using a tongue depressor in the throat could exacerbate this symptom.
D. Respiratory tract infection:
Acute epiglottitis is indeed a type of respiratory tract infection. However, examining the throat with a tongue depressor is not likely to directly precipitate a respiratory tract infection.
