ATI Pathophysiology Exam 1
1. A client is brought to the emergency department after a motor vehicle accident in which she suffered a spinal cord injury at the level of C5. Which of the following assessments should be the priority?
- A. Monitoring urinary output
- B. Monitoring heart rate and rhythm
- C. Monitoring respiratory rate
- D. Monitoring the client's pain levels
Correct answer: B
Rationale: The correct answer is monitoring heart rate and rhythm. With a C5 spinal cord injury, monitoring heart rate and rhythm is crucial as it can impact autonomic regulation. This level of injury can affect cardiac function due to the disruption of sympathetic nerve fibers. Monitoring urinary output may be important to assess for urinary retention, but it is not the priority in this scenario. While monitoring respiratory rate is essential in all patients, in this case, cardiovascular stability takes precedence. Pain management is important but is not the priority when assessing a client with a C5 spinal cord injury.
2. Not realizing that its surface was hot, a woman has quickly withdrawn her hand from the surface of a bowl that she was removing from a microwave. Which phenomena has facilitated the rapid movement of her hand in response to the painful stimulus?
- A. Crossed-extensor reflex
- B. Flexor reflex
- C. Withdrawal reflex
- D. Stretch reflex
Correct answer: C
Rationale: The withdrawal reflex is a protective response that allows a person to quickly remove their hand from a painful stimulus.
3. Which individual is likely to have the best prognosis for recovery from his or her insult to the peripheral nervous system? An adult:
- A. client who developed rhabdomyolysis and ischemic injury after a tourniquet application.
- B. who suffered a bone-depth laceration to the shoulder during a knife attack.
- C. who had his forearm partially crushed by gears during an industrial accident.
- D. client who had nerves transected during surgery to remove a tumor from the mandible.
Correct answer: C
Rationale: The correct answer is C. Crushing-type injuries to the peripheral nervous system generally have a better prognosis compared to nerve transections or lacerations. In the scenario provided, the individual who had his forearm partially crushed by gears during an industrial accident is likely to have a better chance of recovery compared to nerve transection (choice D) or laceration (choice B). Rhabdomyolysis and ischemic injury after tourniquet application (choice A) are not directly related to peripheral nerve injury and do not indicate a better prognosis for recovery.
4. During an assessment of a male client suspected of having a disorder of motor function, which finding would suggest a possible upper motor neuron (UMN) lesion?
- A. Hypotonia
- B. Hyperreflexia
- C. Muscle atrophy
- D. Fasciculations
Correct answer: B
Rationale: Hyperreflexia, or exaggerated reflexes, is a common sign of an upper motor neuron (UMN) lesion. An UMN lesion indicates damage to the central nervous system pathways that control movement. Hypotonia (choice A) refers to reduced muscle tone, which is more indicative of lower motor neuron lesions. Muscle atrophy (choice C) suggests long-standing denervation or disuse of muscles. Fasciculations (choice D) are involuntary muscle contractions that can be seen in lower motor neuron lesions, like in amyotrophic lateral sclerosis (ALS), rather than UMN lesions.
5. Peritonitis is a condition that can result in serious complications. Identify one of the complications.
- A. Increased peristalsis
- B. Dizziness and malaise
- C. Sepsis and shock
- D. Nausea and vomiting
Correct answer: C
Rationale: Corrected Rationale: Peritonitis can lead to severe complications such as sepsis and shock due to the infection spreading in the abdominal cavity. Sepsis is a systemic inflammatory response to infection, and shock is a life-threatening condition where the body's organs are not receiving enough blood flow. Choices A, B, and D are incorrect. Increased peristalsis is not a typical complication of peritonitis; dizziness and malaise, as well as nausea and vomiting, are symptoms rather than complications of the condition.
