Correct Answer is A

Explanation

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. Incisional infection B. Paralytic ileus C. Health care-associated Clostridium difficile D. Fecal impaction

Correct Answer is B

Explanation

b. Paralytic ileus: Absence of bowel sounds, abdominal distention, and no passage of flatus are characteristic signs of paralytic ileus, which is a temporary impairment of bowel motility following surgery.

c. Health care-associated Clostridium difficile: Clostridium difficile infection is associated with diarrhea, abdominal pain, and fever. The absence of bowel sounds and abdominal distention is not consistent with C. difficile infection.

d. Fecal impaction: Fecal impaction is characterized by a blockage of hardened stool in the

rectum or colon, leading to difficulty passing stool. It may cause abdominal discomfort, but it does not typically present with the absence of bowel sounds and abdominal distention seen in paralytic ileus.
