4
Fundamentals of Nursing Care: Concepts, Connections, & Skills Copyright © 2011 F.A. Davis Company Urinary Conditions Dysuria: painful or difficult urination Nocturia: waking at night to urinate Oliguria: urinary output less than 30 mL per hour Polyuria: urinary output greater than 3,000 mL per day
5
Fundamentals of Nursing Care: Concepts, Connections, & Skills Copyright © 2011 F.A. Davis Company Normal Urinary Elimination Urine 95% water 5% solutes Dissolved in the water Waste products resulting from cellular metabolism Accumulate in blood
6
Fundamentals of Nursing Care: Concepts, Connections, & Skills Copyright © 2011 F.A. Davis Company Urinary Waste Products Urea: results from amino acid metabolism Uric acid: results from breakdown of ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) Creatinine: the waste product of muscle metabolism
7
Fundamentals of Nursing Care: Concepts, Connections, & Skills Copyright © 2011 F.A. Davis Company Normal Urinary Elimination Kidneys filter waste products from the blood Eliminate in urine Waste products, excess water, excess electrolytes, hydrogen ions that need to be eliminated, toxins, and other substances resulting from illness
8
Fundamentals of Nursing Care: Concepts, Connections, & Skills Copyright © 2011 F.A. Davis Company Normal Characteristics of Urine Color: straw colored Clarity: clear Amount: 1,000 to 3,000 mL/day Odor: mild; slightly aromatic pH: 4.6 to 8.0 Specific gravity: 1.010 to l.025

Fundamentals of Nursing Care: Concepts, Connections, & Skills Copyright © 2011 F.A. Davis Company Characteristics of Urine Color Directly related to hydration level Normally yellow Darkens with decreased hydration
10
Fundamentals of Nursing Care: Concepts, Connections, & Skills Copyright © 2011 F.A.
