RNSG 1443 RenalA client who is admitted to the hospital with liver cancer and
,ascites is scheduled for a Paracentesis. Which nursing
,intervention would be included in the client’s plan of care?
Cleansing the intestinal tract in preparation
Marking the anesthetic insertion site
Discussing the operating room setup
Having the client void before the procedure
Rationale
Because the trocar is inserted below the umbilicus, having the client void
decreases the danger of puncturing the bladder. Cleansing the intestinal tract
is not necessary because the gastrointestinal tract is not involved in a
paracentesis. The primary health care provider, not the nurse, uses a local
anesthetic to block pain during the insertion of the aspirating needle; marking
the site usually is not done. A paracentesis usually is performed in a treatment
room or at the client’s bedside, not in the operating room.
Which action is characteristic of the hormone vasopressin?
Helps produce concentrated urine
Causes tubular secretion of sodium
Promotes potassium secretion in the collecting duct
Enhances sodium reabsorption in the distal convoluted tubule
Rationale
, The action of the hormone vasopressin released from the posterior pituitary is
to make the distal convoluted tubule and collecting duct permeable to water
so as to maximize reabsorption and produce concentrated urine. The
natriuretic hormones produced from cardiac ventricles cause tubular secretion
of sodium. Aldosterone released from the adrenal cortex promotes potassium
secretion and sodium reabsorption in the distal convoluted tubules and
collecting duct.
Which component of the client’s nephron delivers blood from the
glomerulus into the peritubular capillaries or the vasa recta?
Arcuate artery
Efferent arteriole
Afferent arteriole
Interlobular artery
Rationale
The efferent arteriole is the vascular component of the nephron that delivers
arterial blood from the glomerulus into the peritubular capillaries or the vasa
recta. The arcuate artery is a curved artery of the renal system that surrounds
the renal pyramids. The afferent arteriole is the vascular component of the
nephron that delivers arterial blood from the branches of the renal artery into
the glomerulus. The interlobular artery feeds the lobes of the kidney.
