The nurse is preparing discharge instructions for a patient with a history of diabetes who has just been diagnosed with seizure disorder. The patient has been prescribed hydantoin therapy. What will the patient most likely experience?
Hyperglycemia
Hunger
Hypoglycemia
Pupil dilation
The Correct Answer is C
A. Hyperglycemia:
Hyperglycemia refers to high blood sugar levels. While certain medications can affect glucose metabolism and potentially lead to hyperglycemia as a side effect, this is not typically associated with hydantoin therapy for seizure disorder. Therefore, it is less likely for the patient to experience hyperglycemia as a direct result of taking hydantoin medication.
B. Hunger:
Hunger is not a common side effect of hydantoin therapy for seizure disorder. While some medications may affect appetite or cause changes in eating habits, hunger is not a typical side effect of hydantoin medications such as phenytoin.
C. Hypoglycemia:
Hypoglycemia refers to low blood sugar levels, which can lead to symptoms such as confusion, dizziness, sweating, and weakness. Hydantoin medications, particularly phenytoin, can affect glucose metabolism and increase the risk of hypoglycemia, especially in patients who already have diabetes or are prone to low blood sugar. Therefore, it is important for patients taking hydantoin therapy to monitor their blood sugar levels regularly and be aware of the signs and symptoms of hypoglycemia.
D. Pupil dilation:
Pupil dilation, or mydriasis, is not a common side effect of hydantoin therapy for seizure disorder. While certain medications may affect pupil size, this is not typically associated with hydantoin medications such as phenytoin.

Correct Answer is B
Explanation
A. Decreased pedal pulses:
Decreased pedal pulses are not typically associated with increased intracranial pressure. Instead, they may indicate peripheral vascular disease or reduced perfusion to the lower extremities. Monitoring peripheral pulses is important for assessing circulation but is not directly related to intracranial pressure changes.
B. Hypertension:
Hypertension can be a manifestation of increased intracranial pressure. The body may respond to elevated intracranial pressure by increasing blood pressure to maintain cerebral perfusion pressure. However, hypertension alone is not specific to increased ICP and can have various causes.
C. Peripheral edema:
Peripheral edema is not a typical manifestation of increased intracranial pressure. It may occur in conditions such as heart failure or renal dysfunction but is not directly related to intracranial pressure changes following a craniotomy.
D. Diarrhea:
Diarrhea is not a common manifestation of increased intracranial pressure. Increased ICP is more likely to manifest with symptoms such as headache, nausea, vomiting, altered level of consciousness, and focal neurological deficits.

Correct Answer is A
Explanation
A. Bradycardia, hypertension, and widening pulse pressure
This combination of symptoms is characteristic of Cushing's triad. Bradycardia (slow heart rate), hypertension (elevated blood pressure), and widening pulse pressure (difference between systolic and diastolic blood pressure) are indicative of increased ICP, specifically resulting in the compression of brain structures that regulate vital functions.
B. Widening pulse pressure, headache, and seizure
While headache and seizure may occur in patients with increased ICP, widening pulse pressure alone is not sufficient to meet the criteria of Cushing's triad. The presence of bradycardia and hypertension, along with widening pulse pressure, is more indicative of Cushing's triad.
C. Hypertension, tachycardia, and headache
Hypertension and headache may occur in patients with increased ICP, but the absence of bradycardia and widening pulse pressure makes this option less characteristic of Cushing's triad.
D. Hypotension, tachycardia, and narrowing pulse pressure
Hypotension (low blood pressure) and narrowing pulse pressure are not typically associated with Cushing's triad. Tachycardia (rapid heart rate) may occur in response to increased ICP, but it is usually accompanied by bradycardia rather than hypotension.
