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
Explanation
Choice A: Troponin I is a laboratory test that the nurse should anticipate the provider to prescribe. Troponin I is a protein that is released into the blood when the heart muscle is damaged. Troponin I levels are elevated in clients who have acute myocardial infarction (AMI), which is a heart atack caused by a blockage of blood flow to the heart. Chest pressure and shortness of breath are common signs and symptoms of AMI. Troponin I is a specific and sensitive marker of cardiac injury and can help diagnose AMI and guide treatment.
Choice B: Aspartate aminotransferase (AST) is not a laboratory test that the nurse should anticipate the provider to prescribe. AST is an enzyme that is found in various tissues, such as the liver, heart, skeletal muscle, and kidneys. AST levels are elevated in clients who have liver damage, hepatitis, cirrhosis, or alcohol abuse. AST levels can also be elevated in clients who have AMI, but they are not as specific or sensitive as troponin I. AST is not a reliable indicator of cardiac injury and can be influenced by other factors.
Choice C: B-type natriuretic peptide (BNP) is not a laboratory test that the nurse should anticipate the provider to prescribe. BNP is a hormone that is secreted by the heart when it is stretched or overloaded. BNP levels are elevated in clients who have heart failure, which is a condition in which the heart cannot pump enough blood to meet the
body's needs. Shortness of breath can be a sign of heart failure, but chest pressure is not. BNP is not a specific or sensitive marker of cardiac injury and can be influenced by other factors.
Choice D: Lipase is not a laboratory test that the nurse should anticipate the provider to prescribe. Lipase is an enzyme that is produced by the pancreas and helps digest fats. Lipase levels are elevated in clients who have pancreatitis, which is an inflammation of the pancreas. Pancreatitis can cause abdominal pain, nausea, vomiting, and fever. Chest pressure and shortness of breath are not signs of pancreatitis. Lipase is not a specific or sensitive marker of cardiac injury and has no relation to AMI.
Correct Answer is B
Explanation
Choice a) is incorrect because calcium levels are not directly affected by hemodialysis. Calcium is a mineral that is important for bone health, blood clotting, and muscle contraction. Hemodialysis does not remove calcium from the blood, but it may cause low calcium levels if the dialysate fluid has a lower concentration of calcium than the blood.
Choice b) is correct because potassium levels are decreased by hemodialysis. Potassium is an electrolyte that is essential for nerve and muscle function, especially the heart. Hemodialysis removes excess potassium from the blood, which can build up in people with kidney failure and cause irregular heartbeats, muscle weakness, or even cardiac arrest.
Choice c) is incorrect because protein levels are not decreased by hemodialysis. Protein is a macromolecule that is composed of amino acids and performs various functions in the body, such as building and repairing tissues, transporting substances, and regulating processes. Hemodialysis does not remove protein from the blood, but it may cause low protein levels if the client has a poor diet or loses protein through other means, such as urine or wounds.
Choice d) is incorrect because RBC count is not decreased by hemodialysis. RBCs are red blood cells that carry oxygen throughout the body. Hemodialysis does not remove RBCs from the blood, but it may cause low RBC count if the client has anemia, which is a common complication of kidney failure. Anemia can be caused by reduced production of erythropoietin (a hormone that stimulates RBC production), iron deficiency, or blood loss.
