Creatinine limitations include? Correct Answer-- age, gender, race, diet, and metabolism - Low muscle mass → disproportionately low serum creatinine and overestimation of GFR −GFR may be <50% normal before serum creatinine ↑ Newer marker of GFR Correct Answer-Cystatin C CKD-EPI equation→ most accurate when Correct Answer-GFR is normal/mildly reduced * performs better at higher (normal) values of glomerular filtration rate. Cockroft-Gault and MDRD equations → most accur...

Autoregulation of renal blood flow - correct answers prevents large changes in GFR when there are increases/decreases in BP; regulated neural and hormonal regulation renin-angiotensin-aldosterone system - correct answers -decreased blood pressure causes the juxtaglomerular cells of kidneys to secrete renin which converts angiotensinogen (inactive) to angiotensin I (active) which is then converted into angiotensin II by angiotensin-converting enzyme (ACE) -Angiotensin II stimulates the adr...

NUR 2500 Final Exam Questions and Answers Already Passed What is the pathophysiology of hypertension? Hypertension occurs when there is an increase in blood pressure due to the narrowing or stiffening of blood vessels, leading to increased resistance against blood flow. What are the main risk factors for developing coronary artery disease (CAD)? The main risk factors for CAD include hypertension, high cholesterol, smoking, diabetes, obesity, and a sedentary lifestyle. What is the...

Inversly - answer-phosphorus and calcium are _______ related Decreases, increases - answer-Calcium __________ in renal failure, so phosphorus ______________ Nephron - answer-Functions: filtration, reabsorption, secretion glomerular filtration - answer-The first step in urine formation in which substances in blood pass through the filtration membrane and the filtrate enters the proximal convoluted tubule of the nephron. Glomerular filtration rate GFR - answer-amount of filtrate formed in a...

The nurse reading the operative record of a client who had cardiac surgery notes that the client's cardiac output immediately after surgery was 3.2 L/min. Evaluation of the cardiac output results leads the nurse to make which conclusion? Answer: The cardiac output is below the normal range. The nurse is caring for an older client. Which finding should the nurse expect to note in this client while evaluating renal function? Answer: The glomerular filtration rate (GFR) diminish...

Which statement is true regarding renal blood flow? No autoregulation is found in renal blood flow. The kidneys receive 50% of cardiac output. The kidneys receive mL of blood per minute. The glomerular filtration rate (GFR) is not related to renal blood flow. The kidneys receive almost a quarter of cardiac output. A patient with untreated strep throat is more likely to have with kidneys Nephritic syndrome is caused by an antibody/antigen reaction seen after group a-beta hemolytic strep. ...
