(ED). The ED nurse prepares the patient for admission to which inpatient unit? -
✅✅ Telemetry/cardiac stepdown
When treating a patient for hyponatremia, which type of drug must be altered to
decrease sodium loss? - ✅✅ Diuretics
Which electrolyte imbalance triggers aldosterone secretion to maintain fluid
balance within the body? - ✅✅ Decreased sodium levels in the extracellular
fluid
What route of fluid loss is non-measurable? - ✅✅ Perspiration
What is the major cause of death in patients diagnosed with hypokalemia? - ✅✅
Respiratory insufficiency
Which age-related change of the kidney increases an older adult patient's risk for
dehydration? - ✅✅ Increased water loss
What statement by the student nurse indicates a need for further teaching about the
care to be taken in healthy adults to prevent mild dehydration? - ✅✅ "Consume
more beverages that contain caffeine."
The nurse is providing care to a patient who is diagnosed with dehydration. Which
laboratory finding supports the current diagnosis? - ✅✅ Hypernatremia
Which is the most critical fluid to prevent death? - ✅✅ Blood volume
Which assessment data is the best indication of perfusion after a surgical
procedure? - ✅✅ Urine output
What is the reason for relative dehydration? - ✅✅ Fluid shift from plasma to
interstitial space

sodium loss? - ✅✅ Aldosterone
The nurse is analyzing a patient's serum electrolyte results. Which lab result is of
the highest concern? - ✅✅ Chloride 88 meq/L
A 77-year-old woman is brought to the emergency department by her family after
she has had diarrhea for 3 days. The family tells the nurse that she has not been
eating or drinking well, but that she has been taking her diuretics for congestive
heart failure (CHF). Her laboratory results include a potassium level of 7.0 meq/L.
What is the primary goal of drug therapy for this patient? - ✅✅ Restoring fluid
balance by controlling the causes of dehydration

maintain blood flow to the vital organs? - ✅✅ Increased blood vessel
constriction

potassium levels? - ✅✅ kiwi

and edema to prevent skin breakdown on pressure areas? - ✅✅ Changing
position every 2 hours

surgical unit. Which lab result is severely abnormal? - ✅✅ Magnesium, 6.2
meq/L
Which condition would stimulate the renin-angiotensin II to maintain fluid balance
within the body? - ✅✅ Shock
Which patient is at increased risk for fluid and electrolyte imbalance? ✅✅ 24-
year-old male running athlete
45-year-old man on diuretics
76-year-old bedridden woman
