✍️ Sample CRRN Questions & Answers
1. Which outcome measure is MOST appropriate to track functional independence in rehabilitation patients across multiple diagnoses?
The FIM is the gold-standard measure of functional independence in rehabilitation settings, assessing 18 items across motor and cognitive domains.
2. The cause of esophageal speech.
Esophageal speech is a method of voice production used by individuals who have had their larynx removed (laryngectomy). It involves swallowing air into the esophagus and then expelling it, causing the upper esophageal sphincter to vibrate. This vibration produces a sound that can then be articulated into speech.
3. What is the maximum recommended daily dose of acetaminophen for a healthy adult patient in a rehabilitation setting?
The maximum recommended daily dose of acetaminophen for healthy adults is 4,000 mg/day; however, many clinicians and guidelines recommend limiting to 3,000 mg/day in elderly patients or those with liver disease risk to prevent hepatotoxicity.
4. When teaching a patient with limited mobility about skin inspection, which tool is MOST helpful for visualizing posterior body surfaces independently?
A long-handled mirror enables patients with mobility limitations to inspect posterior surfaces such as the sacrum, buttocks, and heels for early pressure injury detection.
5. Which of the patient's demands must be satisfied FIRST, according to Maslow's hierarchy of requirements?
Maslow's hierarchy of needs posits that basic physiological needs, such as air, water, food, shelter, and sleep, must be satisfied before individuals can attend to higher-level needs. These are fundamental for survival and well-being, making them the absolute priority in patient care. Addressing these foundational needs is essential for overall health and progress.
6. A patient with upper motor neuron (spastic/reflexic) neurogenic bowel from SCI requires bowel care. Which intervention is MOST appropriate to trigger reflex defecation?
Digital rectal stimulation (DRS) or suppository insertion triggers the anorectal reflex in UMN neurogenic bowel, promoting coordinated reflex evacuation.
