Which practice is recommended to prevent human immune deficiency virus (HIV) transmission?

Choice A reason: Blanching is the term that the nurse documents for this finding, because it describes the temporary whitening of the skin when pressure is applied. Blanching indicates that the blood vessels in the skin are constricted or compressed, and that the blood flow is reduced or interrupted. Blanching can be a normal response to cold, stress, or pressure, or it can be a sign of a problem, such as ischemia, infection, or inflammation.

Choice B reason: Warmth is not the term that the nurse documents for this finding, because it describes the increased temperature of the skin, not the color change. Warmth indicates that the blood vessels in the skin are dilated or expanded, and that the blood flow is increased or enhanced. Warmth can be a normal response to heat, exercise, or emotion, or it can be a sign of a problem, such as infection, inflammation, or allergy.

Choice C reason: Redness is not the term that the nurse documents for this finding, because it describes the original color of the skin, not the color change. Redness indicates that the blood vessels in the skin are dilated or expanded, and that the blood flow is increased or enhanced, as explained above. Redness can be a normal response to heat, exercise, or emotion, or it can be a sign of a problem, such as infection, inflammation, or allergy.

Choice D reason: Nonblanching is not the term that the nurse documents for this finding, because it describes the opposite of what the nurse observed. Nonblanching means that the skin does not turn white when pressure is applied, but rather remains red or purple. Nonblanching indicates that the blood vessels in the skin are damaged or ruptured, and that the blood has leaked into the surrounding tissues. Nonblanching can be a sign of a serious problem, such as bruising, bleeding, or necrosis.

Choice A reason: This is not the best intervention because it is timeconsuming and may not be feasible in some situations. Writing down the message can also be impersonal and may not convey the tone or emotion of the speaker. The nurse should use verbal communication as much as possible and supplement it with nonverbal cues, such as gestures, facial expressions, and eye contact.

Choice B reason: This is an incorrect intervention because it can be annoying and ineffective. Talking loudly in the impaired ear can cause discomfort and distortion of the sound. It can also damage the remaining hearing in the ear. The nurse should not shout or raise their voice, but rather speak at a normal volume and enunciate clearly.

Choice C reason: This is the best intervention because it enhances the quality and clarity of the verbal message. Speaking slowly and clearly while facing the client allows the client to see the nurse's mouth movements and facial expressions, which can help them understand the words and the meaning. The nurse should also avoid covering their mouth or chewing gum while speaking.

Choice D reason: This is not the best intervention because it can be inconvenient and impractical. Talking in a regular voice in the good ear may require the nurse to move around the client or position themselves in a certain way. It can also make the client feel isolated or singled out. The nurse should try to communicate with the client in a way that is comfortable and respectful for both parties.
