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 D
Explanation
A. Approximately 18 lbs. 6 oz.:
This option represents an overestimation of the expected weight. Doubling the birth weight of 8 lbs. 2 oz. would be 16 lbs. 4 oz., so this choice is higher than the expected weight.
B. Approximately 14 lbs. 8 oz.:
This option represents an underestimation of the expected weight. Doubling the birth weight of 8 lbs. 2 oz. would be 16 lbs. 4 oz., so this choice is lower than the expected weight.
C. Approximately 24 lbs. 4 oz.:
This option represents a significant overestimation of the expected weight. Doubling the birth weight of 8 lbs. 2 oz. would be 16 lbs. 4 oz., so this choice is much higher than the expected weight.
D. Approximately 16 lbs. 4 oz.:
This option is the correct estimate based on doubling the birth weight of 8 lbs. 2 oz. It accurately reflects the expected weight of a 6-month-old child according to developmental milestones.
Correct Answer is ["1.75"]
Explanation
To administer the correct dose of ampicillin IM, the nurse needs to calculate the amount of solution to draw up from the vial.
The vial contains 1 g of ampicillin in 5 mL of solution, which means that each mL has 200 mg of ampicillin.
To get 350 mg of ampicillin, the nurse needs to divide 350 by 200, which gives 1.75.
Therefore, the nurse needs to draw up 1.75 mL of solution for an IM injection.
