Which condition would indicate to the nurse that the patient has a phenytoin (Dilantin) toxicity?
Nystagmus
Strabismus
Blurry vision
Amblyopia
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 ["0.6"]
Explanation
To calculate the dose of diazepam in mL, the nurse should use the formula:
Dose (mL) = Desired dose (mg) / Available dose (mg/mL)
Plugging in the values from the question, we get:
Dose (mL) = 3 mg / 5 mg/mL
Simplifying, we get:
Dose (mL) = 0.6 mL
Therefore, the nurse should administer 0.6 mL of diazepam IM.

Explanation
A. Muscle tremors:
Muscle tremors, particularly resting tremors, are a hallmark feature of Parkinson's disease. These tremors typically occur in the hands, fingers, arms, legs, jaw, or head and may worsen with stress or inactivity.
B. Slow body movement (bradykinesia):
Bradykinesia refers to slowness of movement and is another key symptom of Parkinson's disease. Patients may have difficulty initiating movement, experience a decrease in spontaneous movement (hypokinesia), and demonstrate reduced range of motion.
C. Rigidity:
Rigidity, or stiffness of the muscles, is a common symptom of Parkinson's disease. It often affects the limbs and trunk and can contribute to difficulty with movement and posture.
D. Pill rolling:
Pill rolling refers to a specific type of tremor characterized by rhythmic, rolling movements of the thumb and fingers, resembling the action of rolling a pill between the fingers and thumb. This tremor is commonly seen in Parkinson's disease.
E. Lack of facial expression:
Parkinson's disease can lead to a reduced range of facial expressions, also known as hypomimia or "masked facies." Patients may have a fixed, expressionless facial appearance and reduced blinking.
F. Drooling:
Drooling, or excessive salivation, can occur in Parkinson's disease due to impaired swallowing function (dysphagia) and reduced control over oral and facial muscles.
