WHAT IS THE NORMAL VOLUME OF URINE EXCRETED IN A 24-HOUR PERIOD?
1.0 - 1.8 LITERS
ASSUMING NORMAL CONDITIONS, NOTE WHETHER EACH OF THE FOLLOWING SUBSTANCES WOULD BE (A) IN GREATER RELATIVE CONCENTRATION IN THE URINE THAN IN THE GLOMERULAR FILTRATE, (B) IN LESSER CONCENTRATION IN THE URINE THAN IN THE GLOMERULAR FILTRATE, OR (C) ABSENT FROM BOTH THE URINE AND THE GLOMERULAR FILTRATE.

EXPLAIN WHY URINALYSIS IS A ROUTINE PART OF ANY GOOD PHYSICAL EXAMINATION
FINDING ABNORMAL CONSTITUENTS IN THE URINE MAY INDICATE PATHOLOGY
WHAT SUBSTANCE IS RESPONSIBLE FOR THE NORMAL YELLOW COLOR OF URINE?
UROCHROME
WHICH HAS A GREATER SPECIFIC GRAVITY: 1 mL OF URINE OR 1 mL OF DISTILLED WATER? EXPLAIN YOUR ANSWER.
URINE; BECAUSE IT CONTAINS DISSOLVED SOLUTES, WHICH ARE NOT FOUND IN DISTILLED WATER AND ADD TO THE DENSITY OF THE SAMPLE.
EXPLAIN THE RELATIONSHIP BETWEEN THE COLOR, SPECIFIC GRAVITY, AND VOLUME OF URINE.
GENERALLY, THE SMALLER THE VOLUME, THE GREATER THE SPECIFIC GRAVITY AND THE DEEPER THE COLOR.
A MICROSCOPE EXAMINATION OF URINE MAY REVEAL THE PRESENCE OF CERTAIN ABNORMAL URINARY CONSTITUENTS. NAME THREE CONSTITUENTS THAT MIGHT BE PRESENT IF A URINARY TRACT INFECTION EXISTS.
WBCs (PUS), RBCs, AND CASTS
HOW DOES A URINARY TRACT INFECTION INFLUENCE URINE pH?
ALKALINE
HOW DOES STARVATION INFLUENCE URINE pH?
ACID
ALL URINE SPECIMENS BECOME ALKALINE AND CLOUDY ON STANDING AT ROOM TEMPERATURE. EXPLAIN WHY?
BACTERIAL METABOLISM COMPONENTS
PRESENCE OF ERYTHROCYTES IN THE URINE
HEMATURIA
PRESENCE OF HEMAGLOBIN IN THE URINE
HEMOGLOBINURIA
PRESENCE OF GLUCOSE IN THE URINE
GLYCOSURIA
PRESENCE OF ALBUMIN IN THE URINE
ALBUMINURIA
PRESENCE OF KETONE BODIES (ACETONE AND OTHERS) IN THE URINE
KETONURIA
PRESENCE OF PUS (WHITE BLOOD CELLS) IN THE URINE
PYURIA
WHAT ARE RENAL CALCULI, AND WHAT CONDITIONS FAVOR THEIR FORMATION.
THEY ARE KIDNEY STONES; URINARY RETENTION, URINARY TRACT INFECTION, AND ALKALINE URINE.
GLUCOSE AND ALBUMIN ARE BOTH NORMALLY ABSENT IN THE URINE, BUT THE REASON FOR THEIR EXCLUSION DIFFERS. EXPLAIN THE REASON FOR THE ABSENCE OF GLUCOSE.
GLUCOSE IS COMPLETELY REABSORBED (UNLESS PRESENT IN THE BLOOD IN EXCESSIVE LEVELS)
EXPLAIN THE REASON FOR THE ABSENCE OF ALBUMIN.
IT IS TOO LARGE TO PASS THROUGH THE FILTRATION MEMBRANE.

EXPLAIN THE DIFFERENCE BETWEEN ORGANIZED AND UNORGANIZED SEDIMENTS.
ORGANIZED SEDIMENTS ARE SUBSTANCES THAT FORM CRYSTALS OR PRECIPITATE FROM SOLUTION AND UNORGANIZED SEDIMENTS ARE CELLULAR ELEMENTS (WBC, RBC, ETC.)
