CRRN test exam questions and correct answers.
Werickes' area - impaired language comprehension. Despite this impaired comprehension, speech may have a
normal rate, rhythm, and grammar. The most common cause of Wernicke's aphasia is an ischemic stroke
affecting the posterior temporal lobe of the dominant hemisphere. Word Salad
Broca's area - non-fluent aphasia in which the output of spontaneous speech is markedly diminished and there is
a loss of normal grammatical structure. Specifically, small linking words, conjunctions, such as and, or, and but,
and the use of prepositions are lost. limited language
Braden Scale - A Braden scale score below 16 indicates increased risk for pressure ulcer development. While the
specific factors increasing risk might include incontinence or noncompliance, the score alone does not provide
that information. The score does not indicate whether the patient's skin is intact or not, just that there is elevated
risk for skin breakdown.
Domains - 1. Nurse led intervention
2. Promotion of successful living
3. Leadership
4. interprofessional care
Hydrocolloid dressings - Lower infection rates, impermeable to bacteria, absorbs exudate. don't use for heavily
draining wounds.
Time to sit up after tube feed - 30-45 minutes
AD manefestations - Autonomic hyperreflexia is a medical emergency that occurs in persons with T6 spinal cord
injury and above. It is characterized by hypertension, flushing and perspiration above the level of injury,
bradycardia, and goose-flesh below the level of the lesion. These signs and symptoms are caused by the body's
attempt to compensate for the brain's inability to interpret and accurately take action on a stimulus
Ranchos Los Amigos -
Foot Drop - Dorsiflexion is flexion of the foot upward - compared to plantar flexion, which is flexion of the toes
and foot toward the sole. Failure of dorsiflexion results in foot drop, where the toes catch on the ground during
the swing phase of walking. The quadriceps are not involved in foot drop, although weakness of the quadriceps
can be a result of prolonged bed rest. Foot-drop is not a normal outcome of any condition
Diffuse axonal injury - DAI is a widespread brain injury, from deceleration and rotational forces, that does not
visualize on CT or MRI. Gunshot wound, contusion, and SDH are all focal injuries, not DAI
Lewin's Change Theory - Moving
Explanation
According to the Lewin Theory of Change, change occurs in 3 stages, beginning with unfreezing, in which the
behavior equilibrium needs to be destabilized or unfrozen before the old behavior can be unlearned and new
behavior adopted. In the 2nd stage of moving, the group moves toward the change to more acceptable behavior.
The last stage is refreezing, where the change is moved to a state of equilibrium and stabilized to prevent
regression. Regression is not a stage in Lewin's theory. It is what can happen in the 2nd stage of moving, before
refreezing and stabilization occur.
The law that allows former employees to continue coverage up to 18 months after voluntary or involuntary
separation from an employer is called: - The Consolidated Omnibus Reconciliation Act (COBRA) allows former
employees to continue coverage after separation from an employer. The legislation in the other items may be
