Choice A reason: Massaging the legs of a client with DVT is contraindicated due to the risk of dislodging a thrombus, which could result in a pulmonary embolism. This action increases the risk of embolic events and must be avoided. Choice B reason: Antiembolic stockings should be removed at least once per shift (every 8 hours) to assess skin integrity and promote circulation. Leaving them on for 24 hours without removal can lead to skin breakdown and impaired perfusion. Choice C reason: Measuring the legs with a tape measure ensures the correct stocking size is selected. Proper sizing is essential for effective compression therapy, which helps prevent clot propagation and promotes venous return. Choice D reason: Folding the stockings at the top can create a tourniquet effect, compromising circulation and increasing the risk of venous stasis. Stockings should be properly fitted and not altered in a way that impairs their function.
