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

Answer and Explanation

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. Fresh fish

Fresh fish does not contain significant amounts of tyramine. Therefore, there is no need to eliminate fresh fish from the client's diet due to its interaction with selegiline.

B. Cheddar cheese

This is the correct answer. Cheddar cheese is a high-tyramine food and should be eliminated from the client's diet when taking MAOIs. Aged cheeses, such as cheddar, contain high levels of tyramine due to the fermentation process, which can increase the risk of a hypertensive crisis when combined with MAOIs.

C. Cherries

Cherries do not contain significant amounts of tyramine. Therefore, there is no need to eliminate cherries from the client's diet due to their interaction with selegiline.

D. Chicken

Chicken does not contain significant amounts of tyramine. Therefore, there is no need to eliminate chicken from the client's diet due to its interaction with selegiline.

A. Nystagmus B. Strabismus C. Blurry vision D. Amblyopia

Correct Answer is A

Explanation

A. Nystagmus:

Nystagmus is an involuntary, rhythmic movement of the eyes, which can be rapid and jerky. It is a common neurological manifestation of phenytoin toxicity. Patients experiencing phenytoin toxicity may exhibit horizontal or vertical nystagmus, which can be detected upon physical examination.

B. Strabismus:

Strabismus, also known as crossed eyes or squint, refers to a misalignment of the eyes. While strabismus can have various causes, it is not typically associated with phenytoin toxicity. Therefore, it is less likely to indicate phenytoin toxicity compared to nystagmus.

C. Blurry vision:

Blurry vision, or visual disturbances, can occur in patients experiencing phenytoin toxicity. However, it is a non-specific symptom and can be observed in various other conditions as well. Patients with phenytoin toxicity may experience blurry vision, double vision (diplopia), or other visual disturbances due to the effects of the medication on the central nervous system.

D. Amblyopia:

Amblyopia, also known as lazy eye, is a condition characterized by reduced vision in one or both eyes. It is typically associated with visual development during childhood and is not directly related to phenytoin toxicity. Therefore, it is less likely to indicate phenytoin toxicity compared to nystagmus or other neurological manifestations.
