Chapter 53 : Assessment of Kidney and Urinary Function Questions
Question 1 of 5
The nurse is caring for a patient with a nursing diagnosis of deficient fluid volume. The nurses assessment reveals a BP of98 / 52 \mathrm{~mm} \mathrm{Hg}$. The nurse should recognize that the patients kidneys will compensate by secreting what substance?
Correct Answer: C
Rationale: When the vasa recta detect a decrease in BP, specialized juxtaglomerular cells near the afferent arteriole, distal tubule, and efferent arteriole secrete the hormone renin. Renin converts angiotensinogen to angiotensin I, which is then converted to angiotensin II. The vasoconstriction causes the BP to increase. The adrenal cortex secretes aldosterone in response to stimulation by the pituitary gland, which in turn is in response to poor perfusion or increasing serum osmolality. The result is an increase in BP.
Question 2 of 5
A nurse is caring for a 73-year-old patient with a urethral obstruction related to prostatic enlargement. When planning this patients care, the nurse should be aware of the consequent risk of what complication?
Correct Answer: A
Rationale: An obstruction of the bladder outlet, such as in advanced benign prostatic hyperplasia, results in abnormally high voiding pressure with a slow, prolonged flow of urine. The urine may remain in the bladder, which increases the potential of a urinary tract infection. Older male patients are at risk for prostatic enlargement, which causes urethral obstruction and can result in hydronephrosis, renal failure, and urinary tract infections.
Question 3 of 5
A patient with elevated BUN and creatinine values has been referred by her primary physician for further evaluation. The nurse should anticipate the use of what initial diagnostic test?
Correct Answer: A
Rationale: Ultrasonography is a noninvasive procedure that passes sound waves into the body through a transducer to detect abnormalities of internal tissues and organs. Structures of the urinary system create characteristic ultrasonographic images. Because of its sensitivity, ultrasonography has replaced many other diagnostic tests as the initial diagnostic procedure.
Question 4 of 5
A patient admitted to the medical unit with impaired renal function is complaining of severe, stabbing pain in the flank and lower abdomen. The patient is being assessed for renal calculi. The nurse recognizes that the stone is most likely in what anatomic location?
Correct Answer: C
Rationale: Ureteral pain is characterized as a dull continuous pain that may be intense with voiding. The pain may be described as sharp or stabbing if the bladder is full. This type of pain is inconsistent with a stone being present in the bladder. Stones are not normally situated in the urethra or meatus.
Question 5 of 5
The nurse is caring for a patient who had a brush biopsy 12 hours ago. The presence of what assessment finding should prompt the nurse to notify the physician?
Correct Answer: C
Rationale: Hematuria and renal colic are common and expected findings after the performance of a renal brush biopsy. The physician should be notified of the patients body temperature, which likely indicates the onset of an infectious process. IV infiltration does not warrant notification of the primary care physician.
