A nurse is caring for a client in the emergency department who has a preliminary diagnosis of a transient ischemic attack (TIA). Which of the following diagnostic testing should the nurse anticipate the provider to prescribe?

To calculate the dose of phenytoin suspension, the nurse should use the following formula:

Dose (mL) = Desired dose (mg) / Concentration (mg/mL) x Volume (mL)

Plugging in the values from the question, we get:

Dose (mL) = 75 mg / (25 mg/5 mL) x 5 mL

Dose (mL) = 15 mL

Therefore, the nurse should administer 15 mL of phenytoin suspension to the patient

A. Lhermitte's sign:

Lhermitte's sign is a neurological symptom characterized by a sensation of electric shock-like pain that radiates down the spine and into the limbs, typically triggered by flexing the neck forward. It is often described as shooting or stabbing pain and is commonly associated with lesions or damage to the cervical spinal cord. Lhermitte's sign is not associated with a tightening sensation around the torso but rather with shooting pain down the spine and limbs.

B. Trigeminal neuralgia:

Trigeminal neuralgia is a neurological condition characterized by severe, shooting pain along the trigeminal nerve, which supplies sensation to the face. The pain is typically triggered by activities such as chewing, speaking, or touching the face. Trigeminal neuralgia causes sudden, intense, electric shock-like pain in the face, particularly in the areas supplied by the trigeminal nerve (e.g., cheek, jaw, forehead). It is not associated with a tightening sensation around the torso.

C. MS hug:

The "MS hug" is a symptom experienced by some individuals with multiple sclerosis, characterized by a sensation of tightness, pressure, or squeezing around the chest, abdomen, or torso. It can feel like a band tightening around the body and may be described as a constricting or girdling sensation. The MS hug is caused by spasms or tightening of the muscles surrounding the rib cage or the intercostal muscles due to damage to the nerves that control muscle function in MS.

D. Paroxysmal spasms:

Paroxysmal spasms refer to sudden, involuntary muscle contractions or spasms that occur intermittently. These spasms can affect various parts of the body and are commonly associated with conditions like multiple sclerosis. However, they typically present as brief, sudden contractions rather than a persistent tightening sensation around the torso.
