Chapter 34: Acute Kidney Injury and Chronic Kidney Disease
A client is being treated for chronic kidney disease (CKD). One of the nurse's responsibilities is to explain to the client the need to keep her blood pressure under control. Why is blood pressure control so important in CKD clients? Elevated blood pressure will result in greater amounts of urine formation and will over-tax renal function. Elevated blood pressure will exacerbate nephron loss and accelerate renal failure. Elevated blood pressure will slow the excretion of protein (proteinuria) and lead to a hypertrophic kidney. Elevated blood pressure will decrease pressure on the nephron with a corresponding decrease in GFR, leading to renal failure.
Elevated blood pressure will exacerbate nephron loss and accelerate renal failure.
A nurse is performing client education with an adult recently diagnosed with chronic kidney disease. Which statement by the client would the nurse most likely want to correct or clarify? "I will be prone to anemia, since I am not producing as much of the hormone that causes my bones to produce red blood cells." "My heart rate might go up because of my kidney disease and my blood might be a lot thinner than it should be." "My kidney problems increase my chance of developing high blood pressure or diabetes." "I will have a risk of either bleeding too easily or possibly clotting too quickly, though dialysis can help minimize these effects."
"My kidney problems increase my chance of developing high blood pressure or diabetes."
A client is in cardiogenic shock following a massive myocardial infarction. The client's family asks the nurse, "Why are the health care providers recommending dialysis since its the heart that is sick?" Which response by the nurse is most appropriate at this time? "It looks like your loved one has been exposed to nephrotoxic drugs like a nonsteroidal anti-inflammatory drug (NSAID) prior to the heart attack." "When a person has such a large heart attack, the kidneys suffer by developing clots which interfere with urine production." "When a person has a large heart attack and goes into shock due to heart failure, there is a decrease in renal perfusion which allows toxins to increase in the blood." "It looks like your family member has had a blockage in the ureters for quite some time and the heart attack has made it more difficult for the blood to be filtered by the kidney."
