ACTUAL EXAM 350 QUESTIONS AND 100%CORRECT
DETAILED ANSWERS WITH RATIONALES (VERIFIED
ANSWERS) | ALREADY GRADED A+
Which intervention in a client with dehydration induced
confusion is most likely to relieve the confusion?
a. increasing the IV flow rate to 250 mL/hr
b. applying oxygen by mask or nasal cannula
c. placing the client in a high Fowler's position
d. Measuring intake and output every four hours -
ANSWER-A
Dehydration most frequently leads to poor cerebra
perfusion and cerebral hypoxia, causing confusion.
Applying oxygen can reduce confusion, even if perfusion

is still less than optimum. Increasing the IV flow rate would
increase perfusion. However, depending on the degree of
dehydration, rehydrating the person too rapidly with IV
fluids can lead to cerebral edema.
Which client is at greatest risk for dehydration?
a. younger adult client on bedrest
b. older adult client receiving hypotonic IV fluid
c. older adult client with cognitive impairment
d. younger adult client receiving hypertonic IV fluid -
ANSWER-C
,3|Page
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
A nurse is caring for several clients. Which client does the
nurse assess most carefully for hyperkalemia?
a. client with type 2 diabetes taking an oral anti-diabetic
agent
b. client with heart failure using a salt substitute
c. client taking a thiazide diuretic for hypertension
, 4|Page
d. client taking non-steroidal anti-inflammatory drugs daily
- ANSWER-B
Many salt substitutes are composed of potassium chloride.
Heavy use cna contribute to the development of
hyperkalemia. The client should be taught to read labels
and to choose a salt substitute that does not contain
potassium. NSAIDs promote the retention of sodium but
not potassium.
An older adult client presents with signs and symptoms
related to dig toxicity. Which age related change may have
contributed to this problem?
