Chapter 57 : Introduction to the Urinary System Questions
Question 1 of 5
The nurse is caring for an 84-year-old client who is being admitted for diagnostic studies for a potential renal disorder. The nurse planning care has initiated a care plan of 'knowledge deficiency related to poor understanding of diagnostic studies as manifested by client statements of not understanding diagnostic procedures and elevated anxiety.' Which nursing intervention(s) does the nurse include in the plan of care?
Correct Answer: A,C,D,E
Rationale: The nurse is caring for a client who is unsure of the diagnostic study and is anxious. The nursing interventions to assist the client begin with understanding knowledge base following an assessment of understanding. Next, remaining with client and answering questions in simple terms alleviates anxiety and opens teaching and communication. If all consents are signed, an ordered sedative may diminish client anxiety. Providing written material at this time is not helpful and may increase anxiety. All instruction should be primarily directed toward the client but include all family members.
Question 2 of 5
The nurse is instructing a health class of high school seniors on the function of the kidney. The nurse is correct to highlight which information?
Correct Answer: B,C,D,F
Rationale: The nurse is correct to highlight all of the options except regulates estrogen and progesterone. The pituitary gland controls hormone secretion.
Question 3 of 5
The nurse is teaching a client with oliguria about the steps that occur during the process of urine formation in the order in which they occur. Place the steps in the order the nurse should review them.
Correct Answer: C,A,D,B,E,F
Rationale: There are three main steps with sub-steps in the complex process of forming urine. The glomerular filtration begins with filtering of the blood plasma by the glomerulus. Next, the filtrate enters Bowman capsule and moves through the tubular system of the nephron and is either absorbed into circulation or excreted as urine. The formed urine drains from the collecting tubules into the renal pelvis and down each ureter to the bladder and out through the urethra.
Question 4 of 5
Which diagnostic test would the nurse expect to be ordered to determine the details of the arterial supply to the kidneys?
Correct Answer: B
Rationale: Angiography provides the details of the arterial supply to the kidneys, specifically the number and location of renal arteries. Radiography shows the size and position of the kidneys, ureters, and bladder. A CT scan is useful in identifying calculi, congenital abnormalities, obstruction, infections, and polycystic diseases. Cystoscopy is used for providing a visual examination of the internal bladder.
Question 5 of 5
A nurse is describing the renal system to a client with a kidney disorder. Which structure would the nurse identify as emptying into the ureters?
Correct Answer: B
Rationale: The renal pelvis empties into the ureter which carries urine to the bladder for storage. The nephron consists of the glomerulus, afferent arteriole, efferent arteriole, Bowman's capsule, distal and proximal convoluted tubules, the loop of Henle, and collecting tubule. The nephron is located in the cortex and carries out the functions of the kidney. The parenchyma is made up of the cortex and medulla.
