The nursing care plan for a client in traction includes regular assessments for venous thromboembolism. When assessing a client's lower limbs, what sign or symptom is suggestive of deep vein thrombosis (DVT)?

Choice A reason: Use of sequential compression devices (SCDs) during times of rest is a helpful intervention to prevent DVT, as it improves the venous return and reduces the stasis of blood in the lower extremities. However, it is not the only or the most effective intervention, as it does not promote the active contraction of the leg muscles.

Choice B reason: Use of abductor pillow while in bed is a necessary intervention to prevent hip dislocation after total hip replacement, as it maintains the alignment and stability of the hip joint. However, it is not a specific intervention to prevent DVT, as it does not enhance the blood circulation or prevent the formation of clots.

Choice C reason: Keeping the heels elevated is a useful intervention to prevent pressure ulcers on the heels, as it reduces the friction and shear forces on the skin. However, it is not a relevant intervention to prevent DVT, as it does not affect the venous flow or prevent the clotting of blood.

Choice D reason: Opioid pain medications as ordered are an important intervention to manage the postoperative pain after total hip replacement, as they provide analgesia and sedation. However, they are not a direct intervention to prevent DVT, as they do not influence the blood coagulation or prevent the thrombus formation. In fact, they may increase the risk of DVT by causing respiratory depression, hypotension, and immobility.

Choice E reason: Early ambulation and leg exercises are the most effective interventions to prevent DVT, as they stimulate the contraction of the leg muscles and improve the blood flow in the veins. They also prevent the pooling and clotting of blood in the lower extremities.

Choice A reason: Heat rash is not an early sign of a fat embolus, as it is a skin condition that occurs when the sweat ducts are blocked and the sweat cannot evaporate. Heat rash is more common in hot and humid environments, and it causes red, itchy, or prickly bumps on the skin. Heat rash is not related to a fat embolus, which is a serious complication of a fracture that involves the release of fat droplets into the bloodstream.

Choice B reason: Tachypnea is an early sign of a fat embolus, as it indicates a respiratory distress that may be caused by the fat droplets blocking the pulmonary capillaries. Tachypnea is a rapid breathing rate that exceeds 20 breaths per minute, and it may be accompanied by dyspnea, chest pain, cough, or hemoptysis. Tachypnea is a sign of hypoxemia, which is a low level of oxygen in the blood, and it requires immediate intervention.

Choice C reason: Bradycardia is not an early sign of a fat embolus, as it is a slow heart rate that is below 60 beats per minute. Bradycardia may be caused by various factors, such as medication, heart disease, hypothyroidism, or vagal stimulation. Bradycardia is not related to a fat embolus, which is a serious complication of a fracture that involves the release of fat droplets into the bloodstream.

Choice D reason: Abdominal cramping is not an early sign of a fat embolus, as it is a pain or discomfort in the abdomen that may be caused by various factors, such as food intolerance, infection, inflammation, or obstruction. Abdominal cramping is not related to a fat embolus, which is a serious complication of a fracture that involves the release of fat droplets into the bloodstream.

Choice E reason: Confusion is not an early sign of a fat embolus, but a late sign that may indicate a cerebral involvement of the fat embolus. Confusion is a state of impaired awareness, orientation, or memory that may be caused by various factors, such as medication, infection, trauma, or hypoxia. Confusion is a sign of cerebral hypoxia, which is a low level of oxygen in the brain, and it requires immediate intervention.
