A nurse assesses an audible grating sound (crepitus) when a client with osteoarthritis moves his knees. What is the cause of this sound?

Choice A reason: This is not the highest priority client because a urinary tract infection (UTI) is a common and treatable condition that affects the lower urinary system, such as the bladder or urethra. A fever of 38.5°C and flank pain can indicate that the infection has spread to the upper urinary system, such as the kidneys, which can cause pyelonephritis. Pyelonephritis is a serious but not lifethreatening complication that requires antibiotic therapy and hydration. The nurse should monitor the client's vital signs, urine output, and pain level and administer the prescribed medication and fluids.

Choice B reason: This is not the highest priority client because a deep vein thrombosis (DVT) is a blood clot that forms in a deep vein, usually in the lower extremities. A positive Homans' sign and edema in the affected leg can indicate that the clot is causing inflammation and obstruction of the blood flow. DVT is a serious but not lifethreatening complication that requires anticoagulant therapy and compression therapy. The nurse should monitor the client's vital signs, leg circumference, and pain level and administer the prescribed medication and stockings.

Choice C reason: This is the highest priority client because a myocardial infarction (MI) is a heart attack that occurs when the blood flow to a part of the heart muscle is blocked, causing tissue damage or death. Chest pain and shortness of breath can indicate that the client is experiencing acute cardiac ischemia, which can lead to cardiac arrest or heart failure. MI is a lifethreatening emergency that requires immediate intervention and treatment. The nurse should activate the rapid response team, monitor the client's vital signs, electrocardiogram, and oxygen saturation, and administer the prescribed medication and oxygen.

Choice D reason: This is not the highest priority client because a stroke is a brain attack that occurs when the blood flow to a part of the brain is interrupted, causing tissue damage or death. Slurred speech and facial droop can indicate that the client is experiencing acute neurological impairment, which can affect their communication and facial expression. Stroke is a serious but not lifethreatening complication that requires prompt evaluation and treatment. The nurse should monitor the client's vital signs, neurological status, and glucose level and administer the prescribed medication and fluids.

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.
