CH. 27 & 89 Urinary System & Disorders IN BASIC NURSING

URINARY SYSTEM - CHAPTER 27

The nurse is reviewing the organs and functions of the urinary system with a client who is to have bladder surgery. What information should the nurse give to the client about the function of the urinary bladder?

• Excretes wastes from the blood, balances body fluids, and forms urine

• Conducts urine from the bladder to the outside of the body for elimination

• Serves as a reservoir for urine

• Conducts urine from the kidneys to the urinary bladder

What is the function of the loop of Henle?

• Filters water, wastes (urea), glucose, and salts out of the blood

• Glucose, amino acids, and salts are actively transported across membranes and returned to the blood

• Concentrates salts by reabsorbing water

• Reabsorbs sodium, water, and the remainder of glucose

What is the function of ADH in the maintenance of the body's homeostasis?

• Assists in regulation of water balance

• Important in blood pressure regulation

• Promotes sodium and water retention

• Increases kidney filtration and blood flow

What is the function of renin?

• Assists in regulation of water balance

• Important in blood pressure regulation

• Promotes sodium and water retention

• Increases kidney filtration and blood flow

Which condition results in insufficient production of erythropoietin?

• Hypoxia

• Cardiac disorders

• End-stage renal disease

• Anemia

What is the function of aldosterone?

• Assists in regulation of water balance

• Important in blood pressure regulation

• Promotes sodium and water retention

• Increases kidney filtration and blood flow

The mineralocorticoid hormone aldosterone responds to which levels of electrolytes? Select all that apply.

• Low levels of calcium

• Low levels of sodium

• High levels of chloride

• High levels of potassium

• Low level of potassium

What is the function of the afferent arterioles?

• Brings highly oxygenated blood to the kidneys

• Supplies blood to the glomeruli

• Carries blood away from the glomeruli

• Empties blood into the inferior vena cava

What is the function of tubular secretion?

• Process of removing particles from a solution by allowing the liquid solvent to pass across a barrier

• Movement of wastes across glomeruli into Bowman's capsule

• Reabsorption of most small proteins and peptides

• Process by which substances move from blood into the urine

The nurse is reviewing the chemical difference between plasma, glomerular filtrate, and urine with a group of nursing students. What components are involved in glomerular filtrate? Select all that apply.

• Blood cells

• Protein

• Glucose

• Urea

• Water
