Which condition would indicate to the nurse that the patient has a phenytoin (Dilantin) toxicity?

Nystagmus

Strabismus

Blurry vision

Amblyopia

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is ["A","B","D"]

Explanation

A. Provide a suction setup at the bedside:

This is a relevant intervention as it ensures that suction equipment is readily available in case the client experiences excessive secretions or vomiting during or after a seizure. It helps maintain a clear airway and prevent aspiration.

B. Elevate the side rails when in bed:

Elevating the side rails can help ensure the client's safety during a seizure by preventing falls from the bed. It is a preventive measure to minimize the risk of injury.

C. Place a bite stick at the bedside:

Placing a bite stick at the bedside is not a recommended intervention. Bite sticks can potentially injure the patient's teeth or mouth during a seizure and are generally not recommended in current practice.

D. Keep an oxygen setup at the bedside:

This is an appropriate intervention as it ensures that oxygen is readily available in case the client experiences respiratory distress or hypoxia during or after a seizure. Oxygen therapy may be needed to support respiratory function.

E. Furnish restraints at the bedside:

Furnishing restraints at the bedside is not a recommended intervention for managing seizures. Restraints should only be used in exceptional circumstances when the client's safety or the safety of others is at risk and should be applied according to institutional policies and legal regulations.

A. Fresh fish B. Cheddar cheese C. Cherries D. Chicken

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.
