Which information about a patient who has a new prescription for phenytoin (Dilantin) indicates that the nurse should consult with the health care provider before administration of the medication?

Patient has slight elevations in liver function test results

Patient's most recent blood pressure is 156/92 mm Hg.

Patient experiences an aura before seizures.

Patient has tonic-clonic seizures.

Answer and Explanation

The Correct Answer is A

A. Patient has slight elevations in liver function test results: Phenytoin is primarily metabolized by the liver, and elevated liver function tests may indicate impaired liver function, potentially affecting the metabolism and clearance of phenytoin. Consultation with the healthcare provider is warranted to assess the risk-benefit ratio of administering phenytoin in the presence of liver function abnormalities.

B. Patient's most recent blood pressure is 156/92 mm Hg: While hypertension is not a contraindication for phenytoin administration, it is important to monitor blood pressure, especially considering the potential cardiovascular side effects of the medication. However, elevated blood pressure alone does not typically warrant consultation before administering phenytoin.

C. Patient experiences an aura before seizures: Experiencing an aura before seizures is a common phenomenon in patients with epilepsy and does not necessarily contraindicate the use of phenytoin. In fact, phenytoin is commonly prescribed to prevent seizures, including those preceded by an aura.

D. Patient has tonic-clonic seizures: Phenytoin is indicated for the treatment and prevention of tonic-clonic seizures, among other seizure types. Therefore, the presence of tonic-clonic seizures would not typically warrant consultation before administering phenytoin.

Correct Answer is B

Explanation

A. Catheterize the patient every 3 to 4 hours: Catheterization may be necessary for urinary retention, which is common in cauda equina syndrome, but it should not be done routinely every 3 to 4 hours. Indwelling catheters increase the risk of urinary tract infections and should be avoided unless necessary.

B. Administer medications to reduce bladder spasm: Bladder spasm is a common complication of cauda equina syndrome and can lead to urinary retention. Medications such as anticholinergics or alpha-adrenergic blockers may be prescribed to reduce bladder spasm and facilitate urine elimination.

C. Assist the patient to ambulate 4 times daily: Ambulation may not be appropriate for a patient with cauda equina syndrome, especially if they have significant motor or sensory deficits. Ambulation should be assessed on an individual basis and may require assistance or adaptive devices.

D. Stabilize the neck when repositioning the patient: Cauda equina syndrome affects the lower spinal cord and does not typically involve the cervical spine. Stabilizing the neck is important in patients with cervical spine injuries but is not directly related to cauda equina syndrome.

A. Hyperthermia B. Weakened gag reflex C. Absence of bowel sounds D. Hypotension E. Polyuria

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

Explanation

A. Slurred speech: This can be a sign of increased ICP but is not typically considered a late sign. It is more often associated with early or moderate increases in ICP when the brain is starting to experience pressure but is not yet at a critical stage.
B. Bradycardia: This is a late sign of increased ICP and is part of Cushing's triad, which includes bradycardia, irregular respirations, and a widened pulse pressure. Bradycardia occurs as a compensatory mechanism to decrease the cerebral blood flow in response to increased ICP.
C. Hypotension: While changes in blood pressure can be associated with ICP, hypotension is not typically a late sign of increased ICP. In fact, hypertension with a widened pulse pressure would be more indicative of increased ICP as part of Cushing's triad.
D. Nonreactive dilated pupils: This is a late sign of increased ICP and indicates brain stem herniation or compression, which is a medical emergency. The pupils become fixed and dilated as the oculomotor nerve is compressed due to increased pressure.
E. Confusion: Confusion can be an early sign of increased ICP as it indicates changes in mental status. However, it is not specifically a late sign of increased ICP, as it can occur at various stages of pressure changes within the brain.
