A nurse is providing teaching about home care to the parent of a child who has scabies.
Which of the following instructions should the nurse include in the teaching?

After an arterial cardiac catheterization, the patient will need to keep their leg straight for several hours following the procedure to prevent bleeding from the catheter insertion site.

Choice B is wrong because droplet isolation precautions are not necessary after an arterial cardiac catheterization.

Choice C is wrong because assisting the child into a supine position may not be necessary and could be uncomfortable for the child.

Choice D is wrong because checking oxygen saturation every 4 hours may not be frequent enough for a child who has undergone an arterial cardiaccatheterization and may require more frequent monitoring of oxygen saturation.

A. Impetigo is a highly contagious superficial bacterial skin infection commonly caused by Staphylococcus aureus or Streptococcus pyogenes. Treatment includes topical antibiotic (bactericidal) ointments such as mupirocin, keeping lesions clean and covered, and good hand hygiene to prevent spread. Applying a bactericidal ointment directly treats the bacterial infection and promotes healing.

B.Soaking hairbrushes in boiling water for 10 minutesis more appropriate for infestations like lice. Impetigo is spread by direct contact with lesions or contaminated items, but routine washing with soap and water is sufficient. Boiling hairbrushes is unnecessary.

C. Acyclovir is an antiviral medication used for infections such as herpes simplex or varicella. Impetigo is bacterial, not viral, so antiviral therapy is inappropriate.

D.Sealingsoft toys in a plastic bag for 14 daysis used for lice management. Impetigo does not require sealing toys for extended periods. Normal laundering of contaminated items is sufficient.
