A nurse is providing discharge teaching to a client who has a new arteriovenous fistula in the right forearm. Which of the following manifestations should the nurse include in the teaching as a possible indication of venous insufficiency?
Cold and numb sensation distal to the fistula site
A raised red rash around the fistula site
Pain in the right arm proximal to the fistula site
Foul-smelling drainage from the fistula site
The Correct Answer is A
Choice A: Cold and numb sensation distal to the fistula site is a possible indication of venous insufficiency. Venous insufficiency is a condition in which the veins have difficulty returning blood from the limbs to the heart, resulting in blood pooling and reduced perfusion. A new arteriovenous fistula can cause increased blood flow through the artery and decreased blood flow through the vein, leading to venous insufficiency. This can manifest as coldness, numbness, tingling, or cyanosis in the fingers or hand below the fistula site.
Choice B: A raised red rash around the fistula site is not a possible indication of venous insufficiency. A raised red rash around the fistula site can indicate an allergic reaction, an infection, or an inflammation of the skin or subcutaneous tissue. The nurse should assess the rash for size, shape, color, texture, temperature, and drainage, and report any signs of infection or inflammation, such as fever, pus, or swelling.
Choice C: Pain in the right arm proximal to the fistula site is not a possible indication of venous insufficiency. Pain in the right arm proximal to the fistula site can indicate arterial insufficiency, which is a condition in which the arteries have difficulty delivering oxygen-rich blood to the tissues, resulting in ischemia and necrosis. Arterial insufficiency can be caused by atherosclerosis, thrombosis, embolism, or vasospasm. The nurse should assess the pain for location, intensity, duration, frequency, and quality, and report any signs of ischemia or necrosis, such as pallor, coolness, weak pulses, or ulceration.
Choice D: Foul-smelling drainage from the fistula site is not a possible indication of venous insufficiency. Foul-smelling drainage from the fistula site can indicate an infection of the fistula or surrounding tissue. The nurse should assess the drainage for color, odor, amount, and consistency, and report any signs of infection or sepsis, such as fever, chills, malaise, or hypotension.

Correct Answer is ["A","C","E"]
Explanation
Choice A Reason: This is correct because placing ice to the bridge of the client’s nose can cause vasoconstriction and reduce blood flow to the nasal mucosa.
Choice B Reason: This is incorrect because tilting the client's head backward can cause blood to drain into the throat and increase the risk of aspiration, nausea, and vomiting.
Choice C Reason: This is correct because moving the client into high-Fowler position can lower the blood pressure in the head and neck and decrease bleeding.
Choice D reason Reason This is incorrect because instructing the client to blow his nose can dislodge any clots that have formed and worsen bleeding.
Choice E Reason: This is correct because applying pressure to the nares can compress the bleeding site and promote clotting.
Correct Answer is B
Explanation
Choice A: Provide a brightly lit environment is not an intervention that the nurse should take. A brightly lit environment can stimulate the brain and increase intracranial pressure. The nurse should provide a quiet and dimly lit environment to reduce sensory stimuli and promote rest.
Choice B: Elevate the head of the bed is an intervention that the nurse should take. Elevating the head of the bed to 30 degrees can help reduce intracranial pressure by facilitating venous drainage from the brain and decreasing cerebral blood volume. The nurse should avoid flexing or extending the neck, which can impede blood flow and increase intracranial pressure.
Choice C: Encourage a minimum intake of 2000 mL (67.6 oz) of clear fluids per day is not an intervention that the nurse should take. A high fluid intake can increase intracranial pressure by increasing blood volume and cerebral edema. The nurse should monitor fluid balance and restrict fluid intake as prescribed to maintain normal osmolality and prevent fluid overload.
Choice D: Teach controlled coughing and deep breathing is not an intervention that the nurse should take. Coughing and deep breathing can increase intrathoracic pressure, which can increase intracranial pressure by reducing venous return from the brain. The nurse should avoid activities that can increase intrathoracic pressure, such as straining, sneezing, or blowing the nose. The nurse should also administer oxygen as prescribed to maintain adequate oxygenation and perfusion of the brain.
