The nurse is preparing to administer medications to a client with osteoarthritis. What is the purpose of the medications?

Choice A reason: Increased agitation is a nonverbal sign of pain, because it indicates that the client is restless, uncomfortable, or distressed by the pain. Agitation can manifest as fidgeting, tossing, turning, moaning, or groaning.

Choice B reason: Decreased attention span is not a nonverbal sign of pain, but rather a cognitive or behavioral sign of pain. Decreased attention span means that the client has difficulty focusing, concentrating, or remembering things, which can be affected by pain. However, decreased attention span is not a direct expression of pain, but rather a consequence of pain.

Choice C reason: Grimacing is a nonverbal sign of pain, because it indicates that the client is experiencing facial muscle tension, contraction, or distortion due to the pain. Grimacing can manifest as frowning, wrinkling the forehead, pursing the lips, or clenching the teeth.

Choice D reason: Reported pain of 5/10 is not a nonverbal sign of pain, but rather a verbal sign of pain. Reported pain of 5/10 means that the client has communicated the intensity of their pain using a numerical scale, which is a subjective and selfreported measure of pain. However, reported pain of 5/10 is not a direct expression of pain, but rather a description of pain.

Choice E reason: Increase in heart rate is a nonverbal sign of pain, because it indicates that the client is experiencing physiological changes due to the pain. Increase in heart rate can manifest as tachycardia, palpitations, or arrhythmias.

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.
