Which prescribed intervention should the emergency department nurse implement first for a patient who is experiencing continuous tonic-clonic seizures?

Monitor level of consciousness (LOC)

Administer lorazepam (Ativan) 4 mg IV.

Obtain computed tomography (CT) scan.

Give phenytoin (Dilantin) 100 mg IV.

Answer and Explanation

The Correct Answer is B

A. Monitor level of consciousness (LOC): While monitoring the patient's level of consciousness is important, administering medication to stop the seizure takes precedence to prevent potential complications associated with prolonged seizure activity.

B. Administer lorazepam (Ativan) 4 mg IV: The priority in managing continuous tonic-clonic seizures is to terminate the seizure activity promptly. Lorazepam is a benzodiazepine that can help to abort seizures and is often used as first-line treatment in the acute setting.

C. Obtain computed tomography (CT) scan: While obtaining diagnostic imaging such as a CT scan may be necessary to evaluate for underlying causes of the seizure, it is not the first
intervention in the acute management of continuous seizures. Stabilizing the patient and stopping the seizure activity take precedence.

D. Give phenytoin (Dilantin) 100 mg IV: Phenytoin is an antiepileptic medication that is used for long-term management of seizures but is not typically administered as first-line treatment during an acute seizure episode. Benzodiazepines like lorazepam are preferred for immediate seizure control.

Correct Answer is D

Explanation

A. Apply an eye patch to the right eye: Applying an eye patch to the right eye would further limit the patient's visual field, exacerbating the homonymous hemianopsia. This intervention is not appropriate for managing hemianopsia.

B. Teach the patient that the left visual deficit will resolve: Homonymous hemianopsia typically results from damage to the visual pathway in the brain and may not resolve completely. While visual rehabilitation techniques may help improve compensatory strategies, it is important to acknowledge and address the permanent nature of the deficit.

C. Approach the patient from the right side: Approaching the patient from the right side may startle them and increase the risk of falls or accidents due to the inability to perceive objects on their left side. The nurse should approach the patient from the unaffected side (the left side) to minimize the risk of injury.

D. Place needed objects on the patient's left side: Placing needed objects on the patient's left side helps compensate for the visual deficit by ensuring that essential items are within the patient's field of vision. This intervention promotes independence and safety for the patient with homonymous hemianopsia.

A. A rising systolic blood pressure B. Change in mood or attention level C. Irregular respiratory rate and depth D. A bounding radial pulse

Correct Answer is B

Explanation

A. A rising systolic blood pressure: While increased intracranial pressure can lead to changes in blood pressure, it is not typically the first sign observed. Changes in blood pressure may occur later in the progression of increased intracranial pressure.

B. Change in mood or attention level: Changes in mood, behavior, or level of consciousness are often early signs of increased intracranial pressure. These changes may include irritability, confusion, restlessness, or lethargy.

C. Irregular respiratory rate and depth: Respiratory changes such as irregular breathing patterns or Cheyne-Stokes respirations can occur with increased intracranial pressure, but they are not typically the first sign observed.

D. A bounding radial pulse: While changes in pulse rate or quality may occur with increased
intracranial pressure, a bounding radial pulse is not typically the first sign observed. It may occur later in the progression of increased intracranial pressure as compensation mechanisms fail.
