Explanation
(A) Tubular support, such as that received with a Jobst garment, applies tension of 10-20 mm Hg. This amount of uniform pressure is necessary to prevent or reduce hypertrophic scarring. Clients typically wear a pressure garment for 6-12 months during the recovery phase of their care. (B) Pressure garments have no ambulatory assistive properties. (C) Pressure garments can worsen the psychological impact of burn injury, especially if worn on the face. (D) Pressure garments do not normalize fluid status.

(A) Chadwick's sign is a presumptive sign of pregnancy. The coloration may not subside from past pregnancy or could be caused by other situations that create vasocongestion.

Stockings must be applied with legs elevated. (C) Support pantyhose help to reduce the varicosity by supporting the vein. They also provide support to the uterus and allow for better return circulation. Hose must be applied like TED stockings. (D) Knee-high stockings create constriction and pressure points that interfere with circulation in the lower extremities.

Explanation
(A) The instillation of erythromycin ophthalmic preparation, not phototherapy, prevents ophthalmia neonatorum. (B) The administration of vitamin K (AquaMEPHYTON) assists the infant's clotting mechanism.
(C) Excessive bilirubin accumulates when the infant's liver cannothandle the increased load caused by the breakdown of red blood cells postnatally. This excessive bilirubin seeps out of the blood and into the tissues, staining them yellow. Phototherapy accelerates the removal of bilirubin from the skin by breaking it down into substances that can be excreted in stool or urine. (D) Phototherapy decreases levels of unconjugated bilirubin, thereby preventing kernicterus.
