During a postpartum assessment, a woman reports that her right calf is painful. The nurse observes edema and redness along the saphenous vein in the right lower leg. Based on this finding, the nurse explains that the probable treatment will involve:

Wash hands before touching each baby. This is because hand hygiene is the most effective way to prevent infection transmission in the nursery. Hand hygiene should be performed before and after every patient contact, as well as before and after wearing gloves or handling equipment. Hand hygiene can be done by washing hands with soap and water or using alcohol-based hand rubs.

Choice A is not correct because adjusting room temperature between 75°F and 80°F is not a measure to protect newborns from infection. The room temperature should be maintained within a comfortable range for newborns, but it does not affect infection risk.

Choice B is not correct because wearing a disposable gown when giving infant care is not a measure to protect newborns from infection. Disposable gowns are part of contact precautions, which are used for patients with known or suspected infections that can be transmitted by direct or indirect contact. They are not necessary for routine infant care.

Choice C is not correct because keeping the newborn dressed warmly is not a measure to protect newborns from infection. Keeping the newborn dressed warmly can help prevent heat loss and hypothermia, but it does not affect infection risk.

This is because cephalhematoma is a collection of blood under the scalp that does not cross the suture line. It is caused by trauma to the head during delivery, such as from vacuum extraction or forceps. It usually appears within a few hours or days after birth and resolves within weeks or months.

Choice B is not correct because nevus flammeus is a type of birthmark that is also known as port-wine stain. It is a flat, red, or purple patch of skin that can appear anywhere on the body, but often on the face. It is caused by abnormal blood vessels in the skin and does not go away over time³.

Choice C is not correct because the molding is the temporary change in the shape of the head due to pressure during delivery. It does not cause swelling or bruising and usually resolves within a few days.

Choice D is not correct because caput succedaneum is a type of swelling that affects the scalp and crosses the suture line. It is caused by fluid accumulation under the scalp due to pressure during delivery. It usually appears at birth and goes away within a few days.
