A nurse is teaching a newly licensed nurse about the peripheral nervous system. Which of the following statements should the nurse make?

"The brain is part of the peripheral nervous system."

"The peripheral nervous system is responsible for memory."

"The spinal cord is part of the peripheral nervous system."

"The peripheral nervous system regulates the body's response to external stimulus."

Answer and Explanation

The Correct Answer is D

A. "The brain is part of the peripheral nervous system." The brain is part of the central nervous system (CNS), not the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, while the PNS includes cranial and spinal nerves that transmit signals between the CNS and the body.
B. "The peripheral nervous system is responsible for memory." Memory is primarily controlled by the CNS, specifically the brain's hippocampus and cerebral cortex. The PNS is not involved in memory storage or recall; instead, it transmits sensory and motor signals between the body and the CNS.
C. "The spinal cord is part of the peripheral nervous system." The spinal cord is part of the central nervous system (CNS), not the PNS. The PNS consists of nerves that extend from the brain and spinal cord to the rest of the body, including sensory and motor neurons.
D. "The peripheral nervous system regulates the body's response to external stimulus." The PNS is responsible for transmitting sensory information from the environment to the CNS and carrying motor responses back to the body. It includes the somatic nervous system (voluntary control of muscles) and autonomic nervous system (involuntary functions like heart rate and digestion). This makes it essential in responding to external stimuli such as pain, temperature, and pressure.

Correct Answer is A

Explanation

A. Lorazepam. Lorazepam (a benzodiazepine) is the first-line medication for status epilepticus because it acts quickly to stop seizures. It enhances gamma-aminobutyric acid (GABA) activity, leading to rapid suppression of neuronal excitability. It is usually administered intravenously (IV) for fast onset.
B. Lisinopril. Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor used for hypertension and heart failure. It has no role in stopping seizures or treating status epilepticus.
C. Phenytoin. Phenytoin is used for long-term seizure control but is not the first-line medication for stopping active seizures. It is often administered after benzodiazepines to help prevent seizure recurrence rather than terminating the ongoing seizure.
D. Atenolol. Atenolol is a beta-blocker used for hypertension and tachycardia. It does not have anticonvulsant properties and is not used to treat seizures.

A. "The purpose of this device is to allow for neck movement during the healing process." B. "The purpose of this device is to immobilize the cervical spine." C. "Apply talcum powder under the vest to limit friction." D. "Turn the screws on the device once each day."

Correct Answer is B

Explanation

A. "The purpose of this device is to allow for neck movement during the healing process." The halo fixation device is designed to completely immobilize the cervical spine, preventing movement to allow for proper healing of spinal injuries. Neck movement is restricted, not encouraged, to avoid further spinal damage.
B. "The purpose of this device is to immobilize the cervical spine." The primary function of a halo fixation device is to stabilize the cervical spine following a spinal cord injury, vertebral fracture, or post-surgical procedure. It provides rigid external fixation to prevent movement that could worsen the injury. Clients must be educated about avoiding activities that may put stress on the device.
C. "Apply talcum powder under the vest to limit friction." Talcum powder should not be used because it can increase skin irritation and moisture buildup, leading to skin breakdown under the vest. Instead, clients should wear a cotton T-shirt under the vest and maintain proper skin hygiene to prevent pressure sores.
D. "Turn the screws on the device once each day." Family members or clients should never adjust the screws. The halo pins should only be adjusted by a healthcare provider, as improper handling can lead to misalignment, pressure injuries, or worsening spinal damage.
