The staff nurse assesses erratic electrical activity on the telemetry monitor while the client is speaking to the nurse via the intercom system. Which task should the nurse instruct the unlicensed assistive personnel to implement?

Fall prevention in clinical settings requires a multifaceted strategy focused on identifying and mitigating environmental and physiological hazards. High-risk populations often exhibit sensory impairment or gait instability, necessitating proactive surveillance to maintain a safe therapeutic environment. Successful mitigation relies on a collaborative partnership between the interdisciplinary team, the client, and their support system to ensure consistent adherence to safety protocols.

Rationale:

A. Liquid on floor surfaces significantly reduces the coefficient of friction, creating an immediate slip hazard for ambulatory clients. Rapid removal of moisture is a fundamental environmental control measure to prevent orthopedic injuries or head trauma. This action must be performed immediately to maintain spatial safety in high-traffic patient care areas.

B. Encouraging clients to utilize the call system ensures that supervised mobility is maintained for those with impaired balance or strength. This practice prevents unassisted transfers that frequently lead to mechanical falls when the client overestimates their physical capacity. Consistent reinforcement of this habit is a key preventative intervention for inpatient safety.

C. Hallway grab bars are designed as static supports for stability while standing or in the bathroom, not as mobility aids for ambulation. Clients should be taught to use dynamic equipment like walkers or canes if they require support while walking long distances. Relying on wall-mounted bars for walking can lead to postural instability and falls.

D. Frequent observation allows the nurse to identify early indicators of restlessness, confusion, or unsafe behaviors that precede fall events. Close monitoring facilitates timely intervention when a client attempts to exit the bed without the necessary assistance. Vigilance is particularly crucial for clients with cognitive deficits or pharmacological-induced sedation.

E. Incontinent clients are at high risk for falls due to urinary urgency and the frequent need to ambulate to the bathroom. Assisting a client only once per shift is clinically inadequate to prevent toileting-related accidents and subsequent falls on wet surfaces. Frequent, scheduled toileting rounds are required to meet the client's elimination needs safely.

F. Educating the client and their family fosters a culture of safety awareness and empowers them to identify potential risks. When families understand the rationale behind fall precautions, they are more likely to comply with safety restrictions and alert staff to hazards. This engagement transforms the family into an active safety advocate.

G. Proper use of corrective lenses and hearing amplification is essential for maintaining environmental orientation and depth perception. Sensory deprivation increases the risk of tripping over obstacles or failing to hear auditory warnings from staff or equipment. Ensuring these devices are functional and in use optimizes the client's neurological processing of surroundings.

Acute respiratory failure manifests through alveolar hypoventilation and severe ventilation-perfusion mismatch, leading to uncompensated acidemia. When the pH drops below 7.35 alongside rising PaCO2, it signifies a failure of respiratory homeostasis and impending exhaustion. Failure to intervene promptly in the presence of concomitant hypoxemia leads to rapid cardiac arrest or neurological damage.

Rationale:

A. Client 4 exhibits euglycemic homeostasis with ABG values within the physiological reference ranges. A pH of 7.41 and PaCO2 of 43 mmHg indicate that the pneumothorax is currently stabilized or resolving. This client does not require immediate prioritization over those with active acid-base imbalances and ventilation failure.

B. Client 1 is the priority due to uncompensated acidemia and a pH of 7.34. The significantly elevated PaCO2 of 55 mmHg and hypoxemia indicate acute respiratory failure superimposed on their chronic condition. This client is at the highest risk for respiratory arrest and requires immediate stabilization and potential ventilatory support.

C. Client 2 shows compensated alkalosis or a compensated state because the pH has returned to the low-normal range of 7.35. While the PaCO2 and PaO2 remain abnormal, the body has achieved metabolic compensation through the kidneys. This client is more stable than Client 1, whose pH remains dangerously low.

D. Client 3 presents with respiratory alkalosis characterized by a pH of 7.48 and a low PaCO2 of 30 mmHg. This is typical of hyperventilation during an acute asthma or reactive airway episode. While they require monitoring, they are not currently in a state of acidotic collapse, making them a secondary priority.
