Answer and Explanation

B.   Sulfonamides can also cause hepatotoxicity, particularly in certain individuals. They are known to occasionally lead to liver enzyme elevations and even more severe liver damage in susceptible patients.
C.   Penicillins are generally considered safe regarding hepatotoxicity; however, there can be rare instances of liver enzyme elevation associated with some penicillin derivatives, particularly in cases of prolonged use or in patients with existing liver disease.

Correct Answer is ["5.3"]

Explanation

1 kilogram equals 2.2 pounds.

The preschooler weighs 29 pounds, which is approximately 13.18 kilograms (29/2.2). The order is for 40 mg/kg/day

13.18 kg * 40 mg/kg = 527.2 mg/day.

Since the medication is to be administered every 12 hours, divide this daily dosage by 2 to get the per dose amount: 527.2 mg/day / 2 = 263.6 mg/dose.

Now, using the concentration of the elixir, which is 250 mg/5 mL, set up a proportion to find out how many milliliters are needed for the prescribed dose: 250 mg : 5 mL = 263.6 mg : X mL.

Solving for X gives us (263.6 mg * 5 mL) / 250 mg = 5.272 mL per dose.

Rounding to the nearest tenth, the nurse should administer 5.3 mL per dose.

A. Apply topical corticosteroids to decrease inflammation. B. Maintain contact precautions. C. Examine child under a wood lamp for possible spread of lesions. D. Carefully remove dressings to not dislodge damaged skin, crusts, and debris.

Correct Answer is B

Explanation

A. Topical corticosteroids are not typically used for impetigo, as it's a bacterial infection.
B. Impetigo is highly contagious, so contact precautions are essential to prevent the spread of infection. This includes wearing gloves and a gown when providing direct care, and using dedicated equipment for the child.
C. A wood lamp is used to examine the skin for fungal infections, not bacterial infections like impetigo.
D. Impetigo typically doesn't require dressings. If dressings are used, they should be removed gently to avoid further skin damage.
