Chapter 57 : Introduction to the Urinary System Questions
Question 1 of 5
The nurse is caring for a client who is brought to the emergency department after being found unconscious outside in hot weather. Dehydration is suspected. Baseline lab work including a urine specific gravity is ordered. Which relation between the client's symptoms and urine specific gravity is anticipated?
Correct Answer: C
Rationale: The nurse assesses all of the data to make an informed decision on client status. On a hot day, the client found outside will be perspiring. When dehydration occurs, a client will have low urine output and increased specific gravity of urine. In kidney disease, the specific gravity may remain relatively constant. The density of distilled water is one. A low specific gravity is noted in a client with high fluid intake and who is not losing systemic fluid.
Question 2 of 5
When describing the functions of the kidney to a client, which would the nurse include?
Correct Answer: C,D,E
Rationale: Functions of the kidneys include control of water balance and blood pressure, regulation of red blood cell production, synthesis of vitamin D to active form, and secretion of prostaglandins. They also produce the enzyme renin.
Question 3 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 4 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 5 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.
