Tachycardia
Clinical Rationale
When a client becomes dehydrated, fluid loss leads to a reduction in total
circulating blood volume (hypovolemia). To compensate for decreased
intravascular volume and maintain adequate tissue perfusion and cardiac output,
the sympathetic nervous system triggers an increase in heart rate (tachycardia).
Clinical Findings in Dehydration
Heart Rate: Tachycardia (fast heart rate) and weak, thready peripheral
pulses.
Blood Pressure: Hypotension (low blood pressure) or orthostatic blood
pressure drops.
Jugular Veins: Flat or collapsed neck veins when lying supine.
Skin and Mucous Membranes: Dry mucous membranes, poor skin turgor
(tenting), and sunken eyes.
Urinary Output: Oliguria (decreased urine output) with concentrated, dark
urine.
Why the Incorrect Options Fail
Distended jugular veins: Indicates fluid volume overload (hypervolemia)
or heart failure, where excess circulating fluid backs up into the venous
system.
Hypertension: Dehydration reduces overall blood volume, which lowers
blood pressure (hypotension), whereas hypertension is tied to fluid retention
or vasoconstriction.
, Hypothermia: Dehydration often prevents the body from sweating
effectively to dissipate heat, which typically leads to an elevated temperature
(fever/hyperthermia) rather than a abnormally low core temperature.

A client with gastroenteritis is admitted to an acute care facility and presents with
severe dehydration and electrolyte imbalances. Diagnostic tests reveal the Norwalk
virus as the cause of gastroenteritis. Based on this information, the nurse knows
that:
enteric precautions must be continued.
enteric precautions can be discontinued.
the client requires an antiviral agent.
the client's infection may be caused by droplet transmission. -ANSWER
✔✔enteric precautions must be continued.

treatment of rabies. Which type of isolation does this client require?
Enteric
Respiratory
