A nurse is providing teaching to a group of clients about the changes that occur when clients experience cataracts. Which of the following statements should the nurse include in the teaching?

A. Respiratory rate of 12/min: A respiratory rate of 12/min is within the normal adult range (12-20 breaths per minute). In the context of increased intracranial pressure (ICP), respiratory rate changes might be noted as part of the Cushing's reflex (which is characterized by bradycardia, hypertension, and abnormal respiratory patterns like Cheyne-Stokes or ataxic breathing), but a rate of 12/min on its own is not indicative of a worsening condition. However, if the patient begins to show signs of irregular or abnormal breathing patterns, this would raise concern.

B. Blood pressure of 108/74 mm Hg: This blood pressure is also within the normal range and does not suggest a worsening of intracranial pressure. In fact, ICP can lead to a rise in blood pressure (due to the body's compensatory mechanisms, known as Cushing's triad), along with bradycardia and abnormal respirations. Thus, a stable blood pressure like 108/74 mm Hg is not concerning in this context.

C. Changes to pupil size and shape: Changes in pupil size, shape, or reactivity are significant indicators of worsening intracranial pressure. Unequal pupils (anisocoria), sluggish or absent response to light, and fixed dilated pupils are signs of brainstem compression or damage, which often occur as ICP increases. This could indicate herniation or severe brain injury, which are worsening conditions.

D. Swelling of the optic nerve: Swelling of the optic nerve, or papilledema, is another important sign of increased intracranial pressure. It occurs due to increased pressure within the skull, which causes congestion and swelling of the optic disc. This finding can be seen on fundoscopy and indicates a worsening condition, as it suggests elevated pressure affecting the brain.

E. Decreasing Glasgow Coma scores: A decreasing Glasgow Coma Scale (GCS) score is a critical indicator of worsening neurologic function in a patient with increased ICP. The GCS is used to assess a patient's level of consciousness, and a decreasing score suggests that the brain's function is deteriorating. This can be caused by worsening edema, brain herniation, or other severe neurological impairments associated with elevated ICP.

A. In the community, the nurse should notify emergency services: In a community setting, such as outside the hospital or in a public area, it is essential to activate emergency medical services (EMS) by calling for help immediately when initiating CPR.

B. Compression rates and depths vary depending on the setting: Compression rates and depths for CPR follow standardized guidelines set by organizations such as the American Heart Association (AHA) and may not significantly differ between community and hospital settings. These guidelines typically recommend a compression rate of 100-120 compressions per minute and a compression depth of at least 2 inches (5 centimeters) for adults.

C. In the hospital, codes are addressed by an interprofessional team: In a hospital setting, cardiac arrest situations are typically addressed by an interprofessional team consisting of physicians, nurses, respiratory therapists, and other healthcare providers. This team-based approach allows for coordinated efforts in resuscitation, including advanced interventions such as airway management, medications, and defibrillation.

D. In the community, the nurse might use laypeople for assistance: In a community setting, especially if the nurse is providing CPR outside of a healthcare facility, there may be a need to involve laypeople or bystanders for assistance. Promptly recruiting bystanders to call for help, retrieve an AED if available, or assist with chest compressions can improve outcomes for the victim of cardiac arrest.

E. In the community, the use of automated external defibrillators (AEDs) requires the presence of a health care provider: In many community settings, including public places like shopping malls, airports, and schools, automated external defibrillators (AEDs) are available for use by laypeople or bystanders. While the presence of a healthcare provider is beneficial, AEDs are designed to provide audio and visual instructions for use by individuals without medical training, allowing for rapid defibrillation in cases of sudden cardiac arrest.
