A nurse is collecting a medication history from a client who is scheduled to have a cardiac catheterization. Which of the following medications taken by the client interacts with contrast material and places the client at risk for acute kidney injury?
Carvedilol
Nitroglycerin
Atorvastatin
Metformin
The Correct Answer is D
Choice A: Carvedilol is not a medication that interacts with contrast material and places the client at risk for acute kidney injury. Carvedilol is a beta-blocker that lowers blood pressure and heart rate by blocking the effects of adrenaline on the heart and blood vessels. Carvedilol does not affect kidney function or contrast excretion, but it can cause hypotension, bradycardia, or heart failure in some clients.
Choice B: Nitroglycerin is not a medication that interacts with contrast material and places the client at risk for acute kidney injury. Nitroglycerin is a vasodilator that relaxes the smooth muscles of the blood vessels and increases blood flow to the heart. Nitroglycerin does not affect kidney function or contrast excretion, but it can cause hypotension, headache, or flushing in some clients.
Choice C: Atorvastatin is not a medication that interacts with contrast material and places the client at risk for acute kidney injury. Atorvastatin is a statin that lowers cholesterol levels by inhibiting an enzyme that produces cholesterol in the liver. Atorvastatin does not affect kidney function or contrast excretion, but it can cause liver damage, muscle pain, or rhabdomyolysis in some clients.
Choice D: Metformin is a medication that interacts with contrast material and places the client at risk for acute kidney injury. Metformin is an oral antidiabetic drug that lowers blood glucose levels by decreasing hepatic glucose production and increasing insulin sensitivity. Metformin can accumulate in the kidneys and cause lactic acidosis, a life-threatening condition characterized by high levels of lactic acid in the blood. Contrast material can worsen kidney function and increase the risk of lactic acidosis in clients taking metformin. Therefore, metformin should be discontinued before and after the procedure as prescribed.

Correct Answer is D
Explanation
Choice A: Weight gain is not a manifestation of left-sided heart failure. Weight gain is more likely to occur in right-sided heart failure, as the blood backs up in the systemic circulation and causes fluid retention and edema in the body.
Choice B: Anorexia is not a manifestation of left-sided heart failure. Anorexia is a loss of appetite, which can have many causes, such as psychological disorders, infections, medications, or cancer. Left-sided heart failure does not directly affect appetite, but it can cause nausea, fatigue, and weakness.
Choice C: A distended abdomen is not a manifestation of left-sided heart failure. A distended abdomen is more likely to occur in right-sided heart failure, as the blood backs up in the portal vein and causes increased pressure in the liver and spleen. This can lead to hepatomegaly, splenomegaly, ascites, and varices.
Choice D: Breathlessness is a manifestation of left-sided heart failure. Breathlessness, or dyspnea, is a sensation of difficulty breathing or shortness of breath. Breathlessness occurs in left-sided heart failure, as the blood backs up in the lungs and causes pulmonary congestion and edema. This impairs gas exchange and reduces oxygen delivery to the tissues.
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.
