A patient suffering from a tumor in the hypothalamus produces excessive amounts of ADH, a condition called syndrome of inappropriate ADH (SIADH) production. For this patient, the excessive ADH production is chronic and has persisted for many months. A student nurse keeps a fluid intake-output record on the patient. She is surprised to find that fluid intake and urinary output are normal. What effect was she expecting? Can you explain why urinary output is normal?

- Mr. Miles, a 65-year-old man, is visiting his health care provider for an annual checkup. He tells you that he has been experiencing difficulty with urination, including increased frequency, urinating more at night, difficulty starting his urine stream, and dribbling after urination. He states that after urination, he feels like his bladder is not emptied. 1. What diagnosis is suggested by Mr. Miles's symptoms? 2. What classes of drugs do you expect will be prescribed for Mr. Miles, and how will these drugs work? 3. What important teaching points will you include regarding the diagnosis and its treatment?arrow_forwardHow does the path of the ureters through the bladder wall minimize the chances of vesicoureteric reflux (see Related Clinical Terms) and hydronephrosis (see “The Urinary System Throughout Life”)?arrow_forwardThe presence of either protein or glucose in a urinalysis is abnormal, but these two molecules end up in the urine for different reasons. For each of these molecules, briefly describe where in the urine production process (i.e., glomerular filtration, tubular reabsorption or tubular secretion) the problem occurs, and why it might happen.arrow_forward
- How do the renal function tests for this patient compare to a healthy individual?arrow_forwardWhat causes polyuria during the renal insufficiency stage in chronic renal failure? Decreased aldosterone secretion Loss of renal tubule function Decreased blood pressure Increased glomerular filtrate rate Presence of urinary casts in glomerular filtratearrow_forwardCreatinine is usually more accurate marker of kidney function than urea, discuss.arrow_forward
- Obstructive uropathy involves the obstruction of urine flow as it exits from kidney toward bladder. Answer all of the following: What happens when urine backs up in kidney? What structure can pressure on tubules damage? When obstruction occurs is it typically unilateral or bilateral? Why or why not?arrow_forwardRenal clearance is the 1) Amount of creatinine in urine 2) Urine concentration of a substance divided by the urine volume per unit of time 3) Volume of plasma from which a substance is removed per unit of time 4) Volume of urine produced per dayarrow_forwardDiscuss why fluid intake is important for a patient diagnosed with a urinary tract infection.arrow_forward
- Number the following structures in order of function (1 to 13) during urine formation. ________afferent arteriole ________ascending limb of loop ________collecting duct ________descending limb of loop ________distal convoluted tubule ________efferent arteriole ________glomerular (Bowman’s) capsule & glomerulus (glomerular capillaries) ________nephron loop ________papillary duct ________proximal convoluted tubule ________renal corpuscle ________thick segment of loop ________thin segment of loop Bladder infections occur when bacteria from outside of the body enter through the urethra and colonize the bladder. Based on the anatomical differences between the sexes, explain why women are more susceptible to bladder infections than men.arrow_forwardArrange the following sets of urinary structures in the correct order for the flow of urine, filtrate, or blood. a. renal pelvis, minor calyx, renal papilla, urinary bladder, ureter, major calyx, and urethra b. distal convoluted tubule, ascending limb of the nephron loop, glomerulus, collecting duct, descending limb of the nephron loop, proximal convoluted tubule, and glomerular capsule c. segmental artery, afferent arteriole, cortical radiate artery, glomerulus, renal artery, interlobar artery, and arcuate artery d. arcuate vein, inferior vena cava, peritubular capillaries, renal vein, interlobar vein, cortical radiate vein, and efferent arteriolearrow_forwardIn renal tubular failure, serum levels of B2 microglobulin are decreased and urine levels are increased.
