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.

Correct Answer is B
Explanation
A. Insert a padded tongue blade into the client's mouth.
This intervention is not recommended. Placing any object, including a padded tongue blade, into the mouth of someone experiencing a seizure poses a risk of injury, such as biting the tongue or breaking teeth. It can also obstruct the airway and increase the risk of aspiration. Therefore, inserting anything into the client's mouth during a seizure is contraindicated.
B. Place a pillow under the client's head.
Placing a pillow under the client's head can help prevent head injury by providing cushioning and support. It can also help maintain the client's airway and reduce the risk of aspiration. Therefore, this intervention is appropriate and helps ensure the client's safety during the seizure.
C. Gently restrain the client's extremities.
Restraining the client's extremities is not recommended during a seizure. It can increase the risk of injury, such as fractures or dislocations, and may exacerbate muscle contractions. It's important to allow the client's movements to occur naturally while taking measures to ensure their safety, such as removing nearby objects and providing a safe environment.
D. Keep the client in a supine position.
It is essential to ensure that the client's head is turned to the side (recovery position) to prevent aspiration and allow for drainage of oral secretions. Additionally, the nurse should remove any nearby objects that could pose a risk of injury during the seizure.
Correct Answer is A
Explanation
A. Orthostatic hypotension:
Orthostatic hypotension, a sudden drop in blood pressure when standing up, is a potential adverse effect of levodopa therapy. This can lead to dizziness and increase the risk of falls, thus supporting the nursing diagnosis Risk for Injury.
B. Nausea and vomiting:
Nausea and vomiting are common side effects of levodopa therapy. While they can cause discomfort and dehydration, they are less directly related to the risk of physical injury compared to orthostatic hypotension.
C. Anorexia and depression:
Anorexia (loss of appetite) and depression can occur as adverse effects of levodopa therapy. While they can affect the patient's overall well-being and quality of life, they are not directly associated with an increased risk of physical injury.
D. Tachycardia and palpitations:
Tachycardia (rapid heart rate) and palpitations are less common adverse effects of levodopa therapy. While they may indicate cardiovascular issues, they are not typically associated with a direct risk of physical injury.
