A nurse is performing cardiopulmonary resuscitation (CPR) for an adult client who is unresponsive. The nurse should evaluate the client's circulation by palpating which of the following pulses?

Choice a) is incorrect because elevating the client’s feet is not the priority action for a hypotensive client. Elevating the client’s feet may help increase the venous return to the heart, but it may also compromise the respiratory status of a client who has esophageal varices and is at risk of aspiration.

Choice b) is incorrect because administering a unit of packed RBCs is not the priority action for a hypotensive client. Administering a unit of packed RBCs may help increase the oxygen-carrying capacity of the blood, but it may also increase the blood viscosity and pressure, which can worsen the bleeding from the esophageal varices.

Choice c) is incorrect because initiating a dopamine IV infusion for the client is not the priority action for a hypotensive client. Initiating a dopamine IV infusion may help increase the blood pressure and cardiac output, but it may also cause vasoconstriction and tachycardia, which can increase the risk of hemorrhage and arrhythmias.

Choice d) is correct because increasing the client’s IV fluid rate is the priority action for a hypotensive client. Increasing the client’s IV fluid rate may help restore the intravascular volume and perfusion, which can prevent shock and organ damage. Increasing the client’s IV fluid rate may also dilute the blood and reduce its viscosity and pressure, which can decrease the bleeding from the esophageal varices.

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.
