What is an ability that is a primary difference in the skills of a
certified critical care nurse compared with nurses certified in
medical-surgical nursing?
a. Diagnose and treat life-threatening diseases
b. Detect and manage early complications of health problems
c. Provide intensive psychologic support to the patient and family

correct answer ✅d. Use advanced technology to assess and
maintain physiologic function
d. A primary characteristic of certified critical care nurses that is
different from those of certified medical-surgical nurses is the
ability to use advanced technology to measure physiologic
parameters accurately to manage life-threatening complications. All
nursing addresses human responses to health problems and
requires knowledge of physiology, pathophysiology, pharmacology,
and psychologic support to the patient and family. Diagnosis and
treatment of life-threatening diseases are roles of medicine.

What is a priority nursing intervention for a patient in the ICU who
is experiencing anxiety caused by being in the ICU environment and
sensory overload?
a. Provide flexible visiting schedules for caregivers.
b. Eliminate unnecessary alarms and overhead paging.
c. Administer sedatives or psychotropic drugs to promote rest.
d. Allow the patient to do as many self-care activities as possible. -
correct answer ✅b. Eliminate unnecessary alarms and overhead
paging.
b. Anxiety in the ICU patient may be related to the environment,
which has unfamiliar equipment, high noise and light levels, and an
intense pace of activity that leads to sensory overload. The nurse
should eliminate as much of this source of stress as possible by
muting phones, limiting overhead paging, setting alarms
appropriate to the patient's condition, and eliminating unnecessary
alarms during care when possible. Offering flexible visiting
schedules for family members with input from the patient and
providing as much autonomy in decisions about care as possible are
indicated when impaired communication and loss of control
contribute to the anxiety. Use of sedation to reduce anxiety should
