NURS 404 Midterm (100% Guaranteed Pass!)

An elderly patient has undergone hip replacement surgery. On the second postoperative day, the nurse finds that the pedal pulses are absent and the lower extremities are cold to the touch. What should the nurse interpret from this finding? A. It is an age-related effect. B. The patient's hip joint has dislocated. C. The room temperature is too cold. D. The patient has venous thrombus formation correct answers D. The absence of pedal pulses and abnormally cold extremities indicate that the patient has venous thrombus formation. Venous thrombus formation occurs because of stagnation or alteration in the blood flow as a result of immobility or injury to the vessel wall during surgery. The thrombus may block the blood supply to the extremities. The clinical manifestations in the patient are not age-related effects. Hip joint dislocation may not result in absence of pedal pulses. A cool room temperature may cause the extremities to become cold but may not lead to an absence of pedal pulses. The nurse assesses a patient's condition and suspects that the patient has footdrop. Which assessment finding supports the nurse's suspicion? A. Internal rotation of entire foot B. Both the legs bent outward at knee C. The foot is permanently fixed in plantar flexion D. Legs curved inward, so knees come together as person walks correct answers C. Footdrop is the leg contracture in which the foot is permanently fixed in plantar flexion, and the patient is unable to lift the toes off the ground. Internal rotation of the entire foot is a postural abnormality called pigeon toes. Bowleg is a condition in which the patient has both the legs bent outward at the knee. Knock-knee is the postural abnormality in which legs curve inward so the knees come together as the person walks.
