The nurse is most concerned about which of these findings in a client with systemic lupus erythematosus (SLE)?

Choice A reason: Using standard precautions is a practice that is recommended to prevent HIV transmission, because it is a set of guidelines that apply to all clients, regardless of their infection status, and that aim to prevent the exposure to blood, body fluids, or other potentially infectious materials. Standard precautions include hand hygiene, use of personal protective equipment, safe handling and disposal of sharps, environmental cleaning, and respiratory hygiene.

Choice B reason: Double gloving is not a practice that is recommended to prevent HIV transmission, because it is not proven to be more effective or safer than single gloving. Double gloving is a technique that involves wearing two pairs of gloves, one over the other, which may provide some extra protection against needlestick injuries or glove punctures, but may also reduce the tactile sensitivity, dexterity, or comfort of the wearer. Double gloving is not a routine practice, but rather an option for certain situations, such as highrisk procedures, long surgeries, or known HIVpositive clients.

Choice C reason: Applying hand sanitizer to gloves during cares is not a practice that is recommended to prevent HIV transmission, because it is not appropriate or hygienic. Applying hand sanitizer to gloves during cares is a practice that can damage the integrity and effectiveness of the gloves, as the alcohol or other chemicals can degrade the material, cause holes, or reduce the fit of the gloves. Applying hand sanitizer to gloves during cares can also create a false sense of security, as the gloves may still be contaminated or ineffective. Hand sanitizer should be applied to the hands before and after wearing gloves, not to the gloves themselves.

Choice D reason: Wearing a mask within three feet of the client is not a practice that is recommended to prevent HIV transmission, because it is not necessary or relevant. Wearing a mask within three feet of the client is a practice that is part of the droplet precautions, which are used to prevent the transmission of infections that are spread by large respiratory droplets, such as influenza, pertussis, or meningitis. HIV is not transmitted by respiratory droplets, but rather by sexual contact, blood, or other body fluids. Wearing a mask within three feet of the client may not provide any protection against HIV, and may also cause stigma or discrimination.

Choice A reason: Heberden's nodes are not a symptom of lupus. Heberden's nodes are bony swellings that form on the distal interphalangeal joints of the fingers. They are a sign of osteoarthritis, which is a degenerative joint disease that causes pain, stiffness, and reduced mobility.

Choice B reason: Chvostek's sign is not a symptom of lupus. Chvostek's sign is a facial twitch that occurs when the facial nerve is tapped near the ear. It is a sign of hypocalcemia, which is a low level of calcium in the blood. Hypocalcemia may be caused by various conditions, such as hypoparathyroidism, vitamin D deficiency, or renal failure.

Choice C reason: OsgoodSchlatter's disease is not a symptom of lupus. OsgoodSchlatter's disease is a condition that affects the growth plate of the tibia, which is the shin bone. It causes pain, swelling, and tenderness below the knee. It is common in adolescents who are active in sports that involve running, jumping, or bending the knee.

Choice D reason: Butterfly rash is a classic symptom of lupus. Butterfly rash is a malar rash that appears across the cheeks and the bridge of the nose. It is a common sign of systemic lupus erythematosus (SLE), which is an autoimmune disease that causes inflammation and damage to various organs and tissues. The rash may flare up or fade depending on the disease activity and exposure to sunlight.
