QUESTIONS AND ANSWERS
Causes of fluid overload. ANSWER - •Excessive fluid replacement
•Kidney failure (late phase)
•Heart failure
•Long term corticosteroid therapy
•Syndrome of inappropriate antidiuretic hormone (SIADH)
•Psychiatric disorders with polydipsia
•Water intoxication
s/s fluid overload. ANSWER - •CV: tachycardia, bounding pulse, HTN, decrease pulse
pressure, JVD, weight gain
•Resp: increase and shallow resp; SOB, crackles lung sounds
•Skin: pitting edema, skin pale and cool to touch
•Neuromuscular: LOC, HA, visual disturbance, muscle weakness, paresthesia
•GI: increase motility, enlarge liver
Assessment for fluid overload. ANSWER - •Assess risk r/t age and diagnosis, history
(overhydration, CHF, kidney disease)
•Assess vital signs why: watch for bounding tachycardia, HTN, dysrhythmias, tachypnea
•Assess lung sounds (crackles) , weight, LOC, Observe JVD
•Assess lab values: electrolytes imbalance and signs and symptoms
• Focus Assessment: skin/extremities/ abdomen and sacrum area for edema
•Assess perfusion: edema may impair perfusion to extremities, assess peripheral and central
pulses, capillary refill, skin color, temp, sensory and motor function
•Observe for urine output
Lab values fluid overload. ANSWER - •Serum osmolality (275-295 mOsm/kg)
•Decrease found in overhydration <275; and < 265 is critical finding
•CBC
•Decrease hemoglobin and hematocrit
•BUN
•decreased BUN
•Electrolytes
•Decreased sodium (shifts due to dilution)
•Urine specific gravity Decrease < 1.005
, fluid overload interventions/goal. ANSWER - •Goal: reduce excess body fluids, promote
desired elimination
•Manage underlying cause
•Restrict dietary sodium intake
•Monitor I/O
•Administer diuretic
•Monitor client's s/s and electrolytes values
•Restrict oral and other fluid intake as prescribed
Fluid overload complications. ANSWER - •Isotonic overhydration
•HF and pulmonary edema
•Seizure
•Coma
Fluid overload medications. ANSWER - Furosemide
Mannitol
S/S of dehydration. ANSWER - •Vital signs: hyperthermia, ST, thread pulse, hypotension,
decrease CVP
•Neuromusculoskeletal: Dizziness, syncope, confusion, weakness, fatigue
•GI: thirst, dry furrowed tongue, N/V, anorexia, weight loss
•Renal: Oliguria
•Other signs: Diminish capillary refill, cool clammy skin, diaphoresis, sunken eyeballs, flat
neck vein
Dehydration assessment. ANSWER - •Assess for condition leading to dehydration:
diarrhea, poor intake, vigorous exercise, vomiting, polyuria, fluid losses (burns, trauma)
clients with drains/NG tube, burns/fluid shifts, overuse of diuretic
Dehydration labs. ANSWER - •Serum electrolytes (hypernatremia)
•Increased serum osmolality normal 275- 295 mOsm/kg; elevated > 295 found in
dehydration; > 320 is critical finding
•CBC elevated H/H
•Elevated urine specific gravity > 1.030
•Increased BUN
Dehydration interventions/goal. ANSWER - •Goal of interventions: replace fluid and
electrolytes to achieve homeostasis
•Closely monitor status and rehydration, avoid overcorrection
•Monitor I/O and weight
•Identify and manage cause- diarrhea, vomiting, blood loss, poor intake
•Oral rehydration is priority if tolerating PO fluids
Dehydration priority interventions. ANSWER - •IV fluid resuscitation/replacement,
general guidelines
