linezolid for an infection. Which of the following
potential complications is the most important for the
nurse to monitor this patient for?
A. Acute delirium
B. Acute kidney injury
C. Acute hepatic failure
D. Sepsis - answer ✅✅B.
Gentamicin is a nephrotoxic agent that places
patients at risk for acute kidney injury, and this risk
is increased in older patients. Acute delirium (A),
liver failure (C), and sepsis (D) are all complications
that could occur in an older adult with an infection
, but would not be caused by the administration of an
antibiotic.
A patient shows a new slight facial droop and the
patient's right arm is weaker than the left. A priority
intervention would be to
A. Obtain a serum glucose level
B. Obtain a full set of vital signs
C. Initiate the stroke protocol
D. Initiate the code response team - answer ✅✅C.
The stroke protocol should be activated as soon as
signs of stroke are identified in a patient. Initial
signs of stroke include facial droop, arm down drift,
and garbled speech. For best outcomes, the time
elapsed between initials signs of stroke and
treatment must be as short as possible.
