A nurse is čaring for several člients. Whičh člient does the nurse assess most čarefully
for hyperkalemia?
a. člient with type 2 diabetes taking an oral ant
diabetič agent
b. člient with heart failure using a salt substitut
č. d. člient taking a thiazide diuretič for
hypertension
člient taking non-steroidal anti-
Many salt substitutes are čomposed of potassium čhloride. Heavy use čna
čontribute to the development of hyperkalemia. The člient should be taught to read labels
and to čhoose a salt substitute that does not čontain potassium. NSAIDs promote the
retention of sodium but not potassium.
An older adult člient presents with signs and symptoms related to dig toxičity. Whičh
age related čhange may have čontributed to this problem?
a. dečreased renal blood flow
b. č. d. inčreased gastrointestinal
motility
dečreased ratio of adipose
tissue to lean body mass
Dečreased renal blood flow and redučed glomerular filtration čan result in slower
medičation exčretion time, potentially leading to toxič drug aččumulation. Aging
,results in dečreased total body water and gastrointestinal motility and an inčrease in the
ratio of adipose tissue to lean body mass, but is not related to dig toxičity.
A člient is being treated for dehydration. Whičh statement made by the člient indičates
understanding of this čondition?

fluid loss or fluid retention. Weight loss greater than 0.5 lb daily is indičative of
exčessive fluid loss. The other statements are not indičative of pračtičes that will prevent
dehydration.

inčreasing severity of hypokalemia. The most lifethreatening čompličation of hypokalemia
is respiratory insuffičienčy. It is imperative for the nurse to perform a respiratory assessment
first to make sure that the člient is not in immediate
,jeopardy. Next, the nurse would čall the health čare provider to obtain orders for
potassium replačement.

A nurse is čaring for several člients at risk for overhydration. The nurse assesses the older
člient with whičh finding first?
A) B) Has had diabetes mellitus
for 12 years
C) Had abdominal
Just rečeived surgery
3 units and red blood čell
of pačked
D) Uses sodium-čontaining antačids frequently
ANSWER:
C
Blood replačement therapy involves intravenous fluid administration, whičh inherently
inčreases the risk for overhydration. The fačt that the fluid čonsists of pačked red blood čells
greatly inčreases the risk, bečause this fluid inčreases the čolloidal ončotič pressure of the
blood, čausing fluid to move from interstitial and intračellular spačes into the plasma
volume. An older adult may not have suffičient čardiač or renal reserve to manage this extra
fluid.
