The nurse has documented the following wound assessment: “Shallow, open, reddened ulcer with no drainage on the center of the right heel.” What stage is the wound?

Choice A reason: Shearing or friction is the force that caused the injury, because it occurs when the skin and underlying tissues move in opposite directions, such as when the client slides down in bed. Shearing or friction can damage the blood vessels and reduce blood flow to the skin, resulting in tissue ischemia, necrosis, and ulceration.

Choice B reason: Pressure or gravity is not the force that caused the injury, because it occurs when the skin and underlying tissues are compressed between a bony prominence and an external surface, such as when the client lies on his back. Pressure or gravity can impair blood flow and oxygen delivery to the skin, resulting in tissue damage and ulceration.

Choice C reason: Chemical or pressure is not the force that caused the injury, because it occurs when the skin is exposed to a substance that causes irritation, inflammation, or corrosion, such as when the client has a wound dressing that contains an antiseptic or a topical agent. Chemical or pressure can damage the skin barrier and increase the risk of infection and delayed wound healing.

Choice D reason: Twisting and bending is not the force that caused the injury, because it occurs when the skin and underlying tissues are stretched or distorted, such as when the client twists his ankle or bends his knee. Twisting and bending can cause sprains, strains, or tears of the ligaments, tendons, or muscles.

Choice A reason: The client instills the prescribed number of eye drops into the conjunctival sac is a correct action, because it ensures that the medication reaches the eye surface and does not spill out. The conjunctival sac is the space between the eyelid and the eyeball.

Choice B reason: The client washes her hands before instilling the eye drops is a correct action, because it prevents the introduction of microorganisms or foreign substances into the eye. Hand hygiene is an essential infection control measure.

Choice C reason: The client sets the cap to the eye drop container down in a manner that does not contaminate it is a correct action, because it preserves the sterility of the eye drop solution and prevents crosscontamination. The cap should be placed on a clean surface with the inner side facing up.

Choice D reason: The client touches the administration dropper to the eye is an incorrect action, because it can cause injury, infection, or contamination of the eye drop solution. The administration dropper should be held close to the eye, but not touch it.
