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

Choice A reason: Primary intention is the correct answer, because it is the type of wound healing that occurs when the wound edges are approximated and closed with sutures, staples, or glue. Primary intention is the fastest and most effective way of wound healing, as it minimizes tissue loss, infection, and scarring.

Choice B reason: Secondary intention is not the correct answer, because it is the type of wound healing that occurs when the wound edges are not approximated and left open to heal by granulation, contraction, and epithelialization. Secondary intention is the slowest and least effective way of wound healing, as it results in more tissue loss, infection, and scarring.

Choice C reason: Tertiary intention is not the correct answer, because it is the type of wound healing that occurs when the wound edges are initially left open and then closed with sutures, staples, or glue after a period of time. Tertiary intention is a delayed form of primary intention, and it is used when the wound is contaminated, infected, or requires drainage.

Choice D reason: Binary intention is not the correct answer, because it is not a real term for wound healing. Binary intention is a madeup term that does not describe any specific process or outcome of wound healing.

Choice A reason: This is not the best action because encouraging range of motion can worsen the symptoms and cause more damage to the nerves and blood vessels. Range of motion is the movement of the joints and muscles through their normal extent. Range of motion can help to prevent stiffness, contractures, and muscle atrophy, but it can also increase the swelling and pressure in the affected area, which can impair the circulation and sensation.

Choice B reason: This is not the best action because applying heat to the affected hand can worsen the symptoms and cause more damage to the tissues. Heat is the transfer of thermal energy from a warmer object to a cooler one. Heat can help to relax the muscles, reduce the pain, and increase the blood flow, but it can also increase the inflammation and edema in the affected area, which can compromise the oxygen and nutrient delivery to the tissues.

Choice C reason: This is the best action because removing the cast can decrease the pressure and restore the circulation and sensation to the affected area. A cast is a rigid device that immobilizes and protects a fractured or injured body part. A cast can help to align the bones, prevent displacement, and promote healing, but it can also cause complications, such as compartment syndrome, infection, or nerve damage. Compartment syndrome is a condition where the pressure inside the muscles increases to dangerous levels, causing severe pain, reduced blood flow, and tissue death. The nurse should remove the cast immediately and notify the physician if the client shows signs of compartment syndrome, such as numbness, tingling, pallor, coolness, or swelling.

Choice D reason: This is not the best action because raising the arm above the level of the heart can worsen the symptoms and cause more damage to the nerves and blood vessels. Raising the arm above the level of the heart can help to reduce the swelling and pain in the affected area, but it can also reduce the blood flow and oxygenation to the area, which can lead to ischemia, necrosis, or gangrene. The nurse should elevate the arm at or below the level of the heart and monitor the pulse, color, temperature, and sensation of the fingers.
