A nurse is collecting data from a client who has an acute myocardial infarction (MI). Which of the following clinical manifestations should the nurse expect to find? (Select all that apply.)

a. Postictal phase: The postictal phase refers to the period following a seizure during which the individual may be drowsy, confused, or sleepy. This phase can last varying amounts of time.

b. Presence of absence seizures: Absence seizures are characterized by brief episodes of staring and altered consciousness but do not typically have a postictal phase with prolonged sleepiness.

c. Aura phase: The aura phase occurs before a seizure and involves sensory or perceptual changes that serve as a warning sign. It does not describe the postictal state.

d. Presence of automatisms: Automatisms are repetitive, non-purposeful movements that can occur during certain types of seizures but do not describe the postictal state of sleepiness.

a. Battle's sign: Battle's sign is bruising over the mastoid process and is not a direct manifestation of increased intracranial pressure.

b. Nuchal rigidity: Nuchal rigidity (stiff neck) is associated with irritation of the meninges and is not a specific sign of increased intracranial pressure.

c. Lethargy: Lethargy or altered level of consciousness is a common manifestation of increased intracranial pressure. It can range from mild drowsiness to severe impairment of consciousness.

d. Polyuria: Polyuria is not a typical manifestation of increased intracranial pressure. Increased urine output may be associated with other conditions, such as diabetes or diuretic use.
