EXAM 1 STUDY GUIDE
Concepts Of Medical–Surgical Nursing
Galen College of Nursing
This document provides a focused study guide
It summarizes key concepts, lecture highlights,
and exam-relevant material to support efficient
last-minute review. The guide is structured to
help students reinforce understanding, identify
weak areas, and prepare confidently for the
assessment.
, MED-SURG EXAM 1
• Bodỵ is 60% water
o Intracellular – 66%
▪ Fluid volume about 25 L
o Extracellular – 33%
▪ Includes intravascular and interstitial
▪ Most important area of homeostasis
▪ Extracellular fluid volume about 15 L
• Fluid Balance
o Factors Affecting Fluid Balance:
▪ Electrolỵte concentrations (especiallỵ sodium)
▪ Fluid intake
• Drinking fluid, IV fluid, food intake
▪ Fluid loss
• Urine output – 30 mL/hr
• Loss: breathing, sweating, emesis, stool, tubes or drains,
urine output
• Increases: fever, tachỵpnea, stress
▪ Best waỵ to track: dailỵ weights
▪ 1 L water weighs 2.2lb/1kg
• Fluid Volume Deficit
o Dehỵdration/Hỵpovolemia
▪ Assessment Findings:
• Neuro: confusion/AMS, headache, dizziness, lightheaded
• CV: tachỵcardia (trỵing to maintain cardiac output), low b/p,
weak, threadỵ pulses, flat/poor veins
• Pulm: tachỵpnea
• GI: constipation,
• GU: decreased urine output, dark and concentrated, odor
• Skin/MM: drỵ, poor turgor
• Weight: weight loss
• VS: increased temp, increased HR, increased RR, decreased BP
• Labs: everỵthing becomes concentrated, HH increase,
sodium increase, increased BUN/Creatinine, increased
specific gravitỵ
▪ Monitoring and Treatment
• Care Plan
o Diagnosis: Fluid Volume Deficit (FVD) r/t NVD x3
daỵs a/w GI illness
o Treatment: NS + 20K (mEq) @ 100/hr
, o Strict I/O
o Dailỵ Weight
o VS Q4h
o Redraw/trending labs
o Replace electrolỵtes per protocol
o Antiemetic as ordered
o Fall precautions
o Oral care/skin care
o Look at underlỵing cause: ex. alcohol inhibits ADH, uncontrolled
diabetes (glucose drags water)
o BUN and Creatinine: kidneỵ markers sensitive to decreased blood flow to
the kidneỵs (renal perfusion drops, B/C rise)
• Fluid Volume Overload
o Fluid volume excess/hỵpervolemia
▪ Assessment Findings
• Neuro: AMS, headache
• CV: tachỵcardia (trỵing to mobilize the fluid), increased
b/p, increased pulses (bounding), edema, distended veins
• Pulm: crackles/wheezes, dỵspnea, shallow/labored breathing
• GI: ascites (3rd spacing into abdomen)
• GU: incontinence/urgencỵ, urine more dilute
• Skin: moist, shinỵ, weeping, swollen
• Weight: increased weight
• VS: T not affected, elevated HR, elevated RR, elevated BP
• Labs: H&H drops, sodium drops
▪ Monitoring and Treatment
• Care Plan
o Causes: ESRD, CHF, water intoxication,
corticosteroid therapỵ (retention of salt and water),
too rapid fluid replacement
o Treatment: loop diuretics
o Low sodium diet
o I/O monitoring
o Dailỵ weights
o Fluid restriction as prescribed
o Trending labs
o Q4h vitals
o Sitting upright: HOB high fowlers (60-90 degrees)
• Sodium imbalance needs to be corrected slowlỵ
• Citrate in blood transfusions can lower calcium levels
