A few days after a Cerebral Vascular Accident, the patient's family asks the nurse if tissue plasminogen activator (tPA) is a drug therapy option now. The nurse's response based on the knowledge that this drug must be used within:
4 hours
1 hour
24 hours
8 hours
The Correct Answer is A
A. 4 hours:
This option indicates that tissue plasminogen activator (tPA) must be administered within 4 hours of the onset of stroke symptoms to be considered as a drug therapy option. tPA is a thrombolytic medication used to dissolve blood clots in ischemic stroke, and its effectiveness is highest when administered promptly after the onset of symptoms.
B. 1 hour:
Administering tPA within 1 hour of stroke onset would be extremely challenging and impractical. It typically takes time for patients to recognize stroke symptoms, seek medical attention, and undergo diagnostic evaluations before tPA administration. While time is of the essence in stroke treatment, 1 hour is too short of a timeframe for most patients to receive tPA.
C. 24 hours:
Administering tPA beyond 4.5 hours of stroke onset is generally contraindicated due to the increased risk of complications, including hemorrhagic transformation of the stroke. While there may be some extended time windows considered for certain patients under specific circumstances, such as those meeting eligibility criteria for extended thrombolytic therapy, 24 hours is outside the standard timeframe for tPA administration.
D. 8 hours:
While tPA administration within 8 hours of stroke onset may be feasible for some patients, it is beyond the standard recommended time window for optimal effectiveness. As mentioned earlier, tPA is most effective when administered within the first 3 to 4.5 hours after the onset of symptoms, with earlier administration associated with better outcomes.

Related Questions
Correct Answer is D
Explanation
A. Dizziness and problems with balance
While dizziness and problems with balance can occur more frequently in older adults due to age-related changes in the vestibular system and other factors, persistent or severe dizziness or balance issues should be evaluated further as they could indicate underlying neurological or medical conditions.
B. Slow papillary response to light
This finding may be considered abnormal, especially if it represents a significant change from the individual's baseline. While age-related changes in pupil function can occur, a slow or sluggish pupillary response to light may indicate dysfunction of the oculomotor nerve or other neurological issues and should be investigated further.
C. Jerky eye movements
Jerky eye movements, such as nystagmus, can be abnormal and may indicate dysfunction of the vestibular system or other neurological conditions. While some degree of nystagmus can occur with age, persistent or severe jerky eye movements should be evaluated further.
D. Absence of the Achilles tendon jerk
This finding may also be considered abnormal. The Achilles tendon reflex, tested using the deep tendon reflex (DTR) examination, can diminish with age but should not be completely absent in the absence of specific medical conditions affecting the reflex arc or spinal cord function.
Correct Answer is C
Explanation
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.
