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

Choice A reason: Popping bursae from standing is not the cause of the grating sound. Bursae are fluidfilled sacs that cushion the joints and reduce friction. Popping bursae may produce a snapping or clicking sound, but not a grating sound.

Choice B reason: A herniated disk in the diseased joint is not the cause of the grating sound. A herniated disk is a condition where the soft inner part of the intervertebral disk bulges out through a tear in the outer layer. A herniated disk may cause pain, numbness, or weakness, but not a grating sound.

Choice C reason: Pieces of bone and cartilage floating is the cause of the grating sound. Osteoarthritis is a degenerative joint disease that causes the breakdown of the cartilage and bone in the joints. Pieces of bone and cartilage may detach and float in the joint space, causing a grating sound when the joint moves.

Choice D reason: Years of an autoimmune process is not the cause of the grating sound. An autoimmune process is a condition where the immune system attacks the body's own tissues. An autoimmune process may cause inflammation, swelling, or damage to the joints, but not a grating sound.

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.
