The nurse is caring for a child with encephalitis. When the nurse enters the room the client is staring blankly and stiffening. There is cyanosis around the child's mouth. What should the nurse's first action be?

Impetigo is a highly contagious superficial bacterial skin infection, most commonly caused by Staphylococcus aureus or Streptococcus pyogenes. It spreads through direct contact and autoinoculation, producing honey-colored crusted lesions primarily in children. Infection control focuses on reducing transmission and preventing lesion spread.

Rationale:

A. Airborne precautions are not indicated because impetigo is transmitted via direct contact and fomites, not aerosolized particles. Standard or contact precautions are appropriate, not airborne isolation, making this option incorrect for infection control.

B. A child with impetigo remains contagious until 24 hours after effective antibiotic therapy begins. Lesions alone do not indicate non-contagious status, so teaching that the child is no longer infectious once the rash appears is incorrect and increases transmission risk.

C. Pain is not a predominant feature of impetigo, as lesions are usually superficial and mildly pruritic rather than painful. Antibiotic therapy addresses infection, but routine pain management is not a primary intervention unless complications occur.

D. Avoiding touching lesions reduces autoinoculation and transmission, which are key mechanisms in impetigo spread. Preventing scratching and hand-to-face contact is essential to limit dissemination to other body areas and reduce transmission to close contacts.

Absence seizures are generalized non-motor epileptic events caused by abnormal thalamocortical oscillations, resulting in brief lapses in consciousness without postictal confusion. They are most common in school-aged children and present as sudden, transient interruption of awareness with immediate recovery.

Rationale:

A. Stiffening and jerking for up to 3 minutes describes a generalized tonic-clonic seizure, characterized by tonic rigidity followed by clonic rhythmic movements. This involves widespread cortical discharge and postictal fatigue, not the brief, non-motor nature of absence seizures.

B. Sudden dropping to the floor suggests an atonic seizure, where there is abrupt loss of postural muscle tone leading to falls. This seizure type is not associated with preserved posture or staring spells typical of absence seizures.

C. Episodes of staring into space are classic for absence seizures, characterized by brief impaired consciousness with behavioral arrest and unresponsiveness. These events typically last seconds and resolve abruptly without confusion or postictal symptoms.

D. Facial twitching with vocalizations and rapid breathing suggests a focal seizure with motor features or evolving generalized seizure activity. These involve localized cortical hyperexcitability and are not consistent with the brief, non-motor presentation of absence seizures.
