answers graded
dehydration - correct answer ✔✔- fluid intake or retention is less than what is
needed to meet the body's fluid needs, resulting in a deficit of fluid volume,
especially plasma volume.
- dehydration causes decreased perfusion which can cause death
- may be an actual decrease in total body water due to little intake or too great of
fluid loss
- may also be caused by no actual loss of body water such as water shifting from
plasma into interstitial space
s/s of dehydration - correct answer ✔✔- increased HR
- weak peripheral pulses
- decreased BP
- orthostatic hypotension (lightheadedness
& dizziness)
- flat neck veins
- flat hand veins
- increased RR
- skin tenting
,- oral mucous membranes are dry and cracked
- tongue may develop deep furrows
- altered mental status (most common in older adults)
- decreased urine output
- reduced temp
- hypovolemia
risk factors for dehydration - correct answer ✔✔- hemorrhage
- vomiting
- diarrhea
- profuse salivation
- fistulas
- ileostomy
- profuse diaphoresis
- burns
- severe wounds
- long term NPO
- diuretic therapy
- GI suction
- hyperventilation
- diabetes insipidus
- difficulty swallowing
- impaired thirst
- unconsciousness
, - fever
- impaired motor function
interventions for dehydration - correct answer ✔✔- fluid replacement
- oral hydration for mild dehydration
- oral rehydration solutions (good when mixed w/ glucose and electrolytes for
vomiting and diarrhea)
-
labs showing dehydration - correct answer ✔✔- elevated levels of hemoglobin,
hematocrit, serum osmolarity, glucose, protein, blood urea nitrogen, and
electrolytes because more water is lost and other substances remain, increasing
blood, concentration (hemoconcentration). Hemoconcentration is not present
when dehydration is caused by hemorrhage because loss of all blood cells and
plasma products occurs together.
best care for a patient with dehydration - correct answer ✔✔- Provide oral fluids
that meet the patient's dietary restrictions (eg, sug-ar-free, low-sodium,
thickened).
- Collaborate with other members of the interprofessional team to determine the
amount of fluids needed during a 24-hour period.
