1. A nurse teaches clients at a community center about risks for
dehydration. Which client is at greatest risk for dehydration?
a. A 36-year-old who is prescribed long-term steroid therapy
b. A 55-year-old receiving hypertonic intravenous fluids
c. A 76-year-old who is cognitively impaired
d. An 83-year-old with congestive heart failure
ANS: C
Older adults, because they have less total body water than
younger adults, are at greater risk for development of
dehydration. Anyone who is cognitively impaired and cannot
obtain fluids independently or cannot make his or her need for
fluids known is at high risk for dehydration.
2. A nurse is caring for a client who exhibits dehydration-
induced confusion. Which intervention should the nurse
implement first?
a. Measure intake and output every 4 hours.
b. Apply oxygen by mask or nasal cannula.
c. Increase the IV flow rate to 250 mL/hr.
d. Place the client in a high-Fowlers position.
ANS: B
Dehydration most frequently leads to poor cerebral perfusion

and cerebral hypoxia, causing confusion. Applying oxygen can
reduce confusion, even if perfusion is still less than optimal.
Increasing the IV flow rate would increase perfusion. However,
depending on the degree of dehydration, rehydrating the client
too rapidly with IV fluids can lead to cerebral edema. Measuring
intake and output and placing the client in a high-Fowlers
position will not address the clients problem.
3. After teaching a client who is being treated for dehydration, a
nurse assesses the clients understanding. Which statement
indicates the client correctly understood the teaching?
a. I must drink a quart of water or other liquid each day.
b. I will weigh myself each morning before I eat or drink.
c. I will use a salt substitute when making and eating my meals.
d. I will not drink liquids after 6 PM so I wont have to get up at
night.
ANS: B
One liter of water weighs 1 kg; therefore, a change in body
weight is a good measure of excess fluid loss or fluid retention.
Weight loss greater than 0.5 lb daily is indicative of excessive
fluid loss. The other statements are not indicative of practices
that will prevent dehydration.

4. A nurse assesses a client who is prescribed a medication that
inhibits angiotensin I from converting into angiotensin II
(angiotensin-converting enzyme [ACE] inhibitor). For which
expected therapeutic effect should the nurse assess?
a. Blood pressure decrease from 180/72 mm Hg to 144/50 mm
Hg
b. Daily weight increase from 55 kg to 57 kg
c. Heart rate decrease from 100 beats/min to 82 beats/min
d. Respiratory rate increase from 12 breaths/min to 15
breaths/min
ANS: A
ACE inhibitors will disrupt the reninangiotensin II pathway and
prevent the kidneys from reabsorbing water and sodium. The
kidneys will excrete more water and sodium, decreasing the
clients blood pressure.
5. A nurse is assessing clients on a medical-surgical unit. Which
adult client should the nurse identify as being at greatest risk
for insensible water loss?
a. Client taking furosemide (Lasix)
b. Anxious client who has tachypnea
