A nurse in a provider's office is caring for a client who has a medical history of rheumatoid arthritis and psoriasis, and a family history of heart disease and arthritis. The client has a 60-year smoking history and denies alcohol or other substance use. They are positive for Helicobacter pylori and are on medication for peptic ulcer disease (PUD). Which three findings from the client's medical record increase their risk for peptic ulcer disease?

Choice A rationale
In the case of hyperkalemia, which can cause fatal cardiac arrhythmias, the most immediate nursing action is to place the patient on a cardiac monitor. This allows for continuous monitoring of the heart's rhythm and immediate detection of any life-threatening changes, which is crucial for timely intervention.

Choice B rationale
Inserting a urinary retention catheter may be necessary for managing oliguria, but it is not the most urgent action when compared to the potential cardiac risks associated with hyperkalemia.

Choice C rationale
Administering spironolactone, a potassium-sparing diuretic, could be part of the treatment for hyperkalemia, but it is not the first action to take. Spironolactone works more slowly and does not address the immediate risk of cardiac arrhythmias.

Choice D rationale
Epoetin alfa (Epogen) is used to treat anemia, particularly in chronic kidney disease, to increase red blood cell production. However, it does not have an immediate effect and is not the priority in the presence of hyperkalemia and potential cardiac complications.

Choice A rationale
The red blood cell (RBC) count is not typically affected by hemodialysis. Hemodialysis is a process that primarily targets the removal of waste products and excess fluid from the blood, not red blood cells.

Choice B rationale
Potassium levels are often elevated in clients with renal failure due to the kidneys' inability to excrete potassium. Hemodialysis helps to remove excess potassium from the bloodstream, thereby decreasing its levels.

Choice C rationale
Calcium levels can be affected by hemodialysis; however, they are more often managed with medication and diet rather than being directly targeted by the dialysis process itself.

Choice D rationale
Protein levels should not decrease significantly as a result of hemodialysis. The dialysis membrane is designed to allow small waste products to pass through while retaining larger molecules like proteins.
