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 A
Explanation
A. Rubella:
Rubella is a viral infection that, when contracted by a pregnant woman during the first trimester, can lead to congenital rubella syndrome (CRS) in the developing fetus. CRS can result in severe birth defects, including heart abnormalities, hearing impairments, and vision problems.
B. Varicella-zoster:
Varicella-zoster virus causes chickenpox. While chickenpox can cause complications in certain populations, it is not specifically associated with severe defects in the fetus when the mother is infected during pregnancy.
C. Rubeola:
Rubeola, commonly known as measles, can lead to complications, but it is not as strongly associated with severe defects in the fetus if the mother is infected during pregnancy compared to rubella.
D. Mumps:
Mumps is generally not associated with severe defects in the fetus when the mother is infected during pregnancy. However, mumps infection during pregnancy can pose risks to the mother's health.
Correct Answer is B
Explanation
A.While cystic fibrosis is characterized by a high concentration of sodium chloride in sweat due to defective chloride channels, this is not the cause of the barrel chest and clubbing of the fingers.
B.The barrel chest and clubbing of the fingers are often seen in children with cystic fibrosis due to chronic hypoxia (lack of oxygen). Chronic lung infections, airway obstruction, and respiratory insufficiency associated with cystic fibrosis lead to prolonged low oxygen levels, which can result in these physical changes.
C.Decreased respiratory capacity, often due to the chronic respiratory issues associated with cystic fibrosis, can result in a barrel chest (increased chest diameter due to air trapping) and clubbing of the fingers (a sign of chronic hypoxia).
D.Decreased respiratory capacity (due to thick mucus and airway obstruction) does contribute to chronic respiratory issues in cystic fibrosis, but the direct cause of the barrel chest and clubbing is the chronic lack of oxygen (hypoxia) rather than decreased capacity alone. The changes in the chest and fingers are a result of prolonged oxygen deprivation.
