What client is a susceptible host most at risk for infection?

Choice A reason: Calling the provider is not the intervention that the nurse should perform first, because it is not the most urgent and relevant action. Calling the provider is a communication intervention, not a respiratory intervention. Calling the provider is an important action, but it should be done after raising the head of the bed, and with accurate and complete information.

Choice B reason: Placing the client in the lithotomy position is not the intervention that the nurse should perform first, because it is not the most urgent and relevant action. Placing the client in the lithotomy position is a positioning intervention, not a respiratory intervention. Placing the client in the lithotomy position is a specific action that is used for pelvic examinations or procedures, not for improving oxygenation.

Choice C reason: Raising the head of the bed is the intervention that the nurse should perform first, because it is the most urgent and relevant action. Raising the head of the bed is a respiratory intervention, not a communication, positioning, or analgesic intervention. Raising the head of the bed is a simple and effective action that can improve the client's breathing, oxygenation, and comfort.

Choice D reason: Obtaining pain medication is not the intervention that the nurse should perform first, because it is not the most urgent and relevant action. Obtaining pain medication is an analgesic intervention, not a respiratory intervention. Obtaining pain medication is an important action, but it should be done after raising the head of the bed, and with a medical order and a proper route.

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.
