An Asian family arrives with their newborn for a well visit. When assessing the infant, the nurse observes the following skin irregularity. What is the nurse's priority action?

Choice A Reason: Seasonal allergies are not a cause of delirium, but a common condition that affects the respiratory system and causes symptoms such as sneezing, runny nose, itchy eyes, or coughing.

Choice B Reason: History of GERD is not a cause of delirium, but a chronic condition that affects the digestive system and causes symptoms such as heartburn, regurgitation, chest pain, or difficulty swallowing.

Choice C Reason: Benzodiazepines are a cause of delirium, especially in older adults or those with cognitive impairment. Benzodiazepines are a class of drugs that act on the central nervous system and cause sedation, relaxation, and reduced anxiety. However, they can also impair memory, attention, orientation, and judgment, and lead to confusion, agitation, hallucinations, or delusions.

Choice D Reason: Completed antibiotics 10 days ago are not a cause of delirium, but a treatment for bacterial infections. Antibiotics can have side effects such as nausea, diarrhea, rash, or allergic reactions, but they do not cause delirium unless they are toxic or interact with other medications.

The correct answers are b, d, and e.

Choice A: Slurred speech.

Slurred speech can be associated with increased ICP due to the pressure effects on the brain areas responsible for speech production. However, it is not typically considered a late sign of increased ICP. It may occur earlier in the progression as the brain's ability to coordinate muscle movements is affected.

Choice B: Bradycardia with a bounding pulse.

Bradycardia with a bounding pulse is a classic sign of Cushing's triad, which is a late and ominous sign of significantly increased ICP. It indicates that the body is attempting to increase arterial blood pressure to overcome the increased ICP and maintain cerebral perfusion. The normal range for adult heart rate is 60-100 beats per minute.

Choice C: Confusion.

Confusion can be an early sign of increased ICP as it can indicate changes in cerebral function. However, it is not specifically a late sign of increased ICP. Early signs of increased ICP can include headache, nausea, and confusion, as the brain is initially responding to the pressure changes.

Choice D: Hypertension with an increasing pulse pressure.

Hypertension with an increasing pulse pressure is another component of Cushing's triad. It reflects the body's compensatory mechanism to preserve cerebral blood flow in the face of rising ICP. An increasing pulse pressure (the difference between systolic and diastolic blood pressure) is a late sign of increased ICP. Normal pulse pressure is typically 30-40 mm Hg.

Choice E: Nonreactive dilated pupils.

Nonreactive dilated pupils are a late sign of increased ICP and indicate pressure on the cranial nerves that control pupil size and reaction to light. This is a grave sign and often indicates impending brain herniation.

Choice F: Hypotension with a decreasing pulse pressure.

Hypotension with a decreasing pulse pressure is not typically associated with increased ICP. In fact, hypertension with a widening pulse pressure would be more indicative of increased ICP as part of Cushing's triad.
