Correct Answer: C

Rationale: Swelling in one leg with edema is a classic sign of deep venous thrombosis (DVT). DVT occurs when a blood clot forms in one or more of the deep veins in the body, usually in the legs. This can lead to swelling in the affected leg due to the impaired venous return caused by the blood clot. It is important for the nurse to recognize this sign because if left untreated, DVT can lead to serious complications such as pulmonary embolism. Therefore, the nurse should further assess the client and notify the healthcare provider for appropriate management.

Correct Answer: C

Rationale: After an embolus becomes trapped in the pulmonary microvasculature, dead space increases. Dead space refers to the portion of the lung that is ventilated but not perfused, resulting in reduced gas exchange. When a pulmonary embolus blocks blood flow within a pulmonary vessel, it leads to a mismatch between ventilation and perfusion in the affected lung region. This mismatch results in increased dead space, as ventilation continues in areas that are not effectively perfused. As dead space increases, the overall efficiency of gas exchange in the lung is impaired, potentially leading to hypoxemia.

Correct Answer: B

Rationale: Option B, washing the lower extremities with mild soap, drying the legs, and applying a light moisturizer, indicates effective teaching for a client with peripheral vascular disease (PVD). Proper hygiene, including gentle washing with mild soap, thorough drying to prevent moisture-related skin breakdown, and moisturizing to prevent dry skin and promote circulation, are key components of self-care for individuals with PVD. Option A is incorrect because sitting with a pillow behind the knees does not specifically address PVD self-care. Option C is incorrect because crossing the left leg over the right while sitting does not relate to appropriate PVD management. Option D is incorrect because smoking in any form is detrimental to vascular health and should be discouraged in PVD management.

Correct Answer: B

Rationale: When caring for a laboring client diagnosed with preeclampsia, it is important to be mindful of certain considerations to ensure the safety and well-being of both the mother and the baby. Placing the client in left lateral position when she feels the urge to push is crucial in cases of preeclampsia as it helps to optimize maternal and fetal oxygenation. This position can help improve blood flow to the placenta and reduce the risk of decreased perfusion due to the elevated blood pressure associated with preeclampsia. By maintaining the client in the left lateral position during pushing, it can help prevent potential complications and support better outcomes for both the mother and baby.

Correct Answer: D

Rationale: When performing medication teaching for the client's family about fibrinolytic therapy with alteplase (rt-PA), the nurse should include information that this medication is administered to break up existing clots and increase cerebral blood flow. rt-PA works by converting plasminogen to plasmin, which helps dissolve clots and restore blood flow to the brain. It is used specifically for ischemic strokes, not hemorrhagic strokes, and is most effective when administered within 3 hours (up to 4.5 hours in some cases) of the stroke symptoms starting. It is associated with potential serious complications, including an increased risk of bleeding, which the nurse should also educate the family about.
