In managing a client experiencing an ischemic stroke, which of the following interventions should be prioritized based on the client's presentation and treatment plan? Select three that apply.

Autonomic dysreflexia is a life-threatening condition that occurs in clients with spinal cord injuries at or above T6 due to an exaggerated autonomic response to a noxious stimulus below the level of injury. It is commonly triggered by bladder distention, bowel impaction, or other irritants. This leads to sudden hypertension, pounding headache, bradycardia, and diaphoresis above the level of injury. Immediate identification and removal of the triggering stimulus is the priority to prevent complications such as stroke or seizures.

Rationale:
A. Administering an antihypertensive medication is not the first action because the priority is to identify and eliminate the underlying cause of the autonomic dysreflexia. While medications may be needed if symptoms persist, treating the trigger (often bladder or bowel-related) is the most immediate and effective intervention. Giving medication without removing the stimulus does not resolve the root cause of the crisis.

B. Placing the client in a supine position is incorrect because it can worsen hypertension by increasing venous return and intracranial pressure. The recommended position is to elevate the head of the bed to reduce blood pressure and promote orthostatic pooling of blood in the lower extremities. Positioning alone, however, is not sufficient without addressing the triggering stimulus.

C. Checking the urinary catheter for kinks is the priority action because bladder distention is the most common cause of autonomic dysreflexia. An obstructed catheter can lead to rapid bladder filling, triggering the autonomic response. Immediate assessment and relief of urinary retention help reduce blood pressure and resolve symptoms quickly.

D. Performing digital rectal stimulation is contraindicated as an initial intervention because it may worsen the episode if a bowel impaction is present and has not been properly prepared for disimpaction. Additionally, rectal stimulation can further increase autonomic stimulation and elevate blood pressure. It should only be done after stabilizing the client and addressing more urgent causes such as bladder obstruction.

Mechanical ventilation is used to support or replace spontaneous breathing in clients with respiratory failure. Safe and effective management requires not only maintaining adequate oxygenation and ventilation but also preventing complications such as ventilator-associated pneumonia, pressure injuries, malnutrition, and prolonged sedation. Care is multidisciplinary and includes weaning readiness assessments, skin integrity protection, treatment of the underlying cause of respiratory failure, and metabolic support.

Rationale:
A. Conducting spontaneous awakening and breathing trials as prescribed is essential because it helps assess readiness for weaning from mechanical ventilation. These trials reduce sedation and evaluate the client’s ability to breathe independently. They decrease ventilator dependence and improve outcomes by promoting earlier extubation when appropriate.

B. Frequent repositioning to prevent pressure ulcers is necessary because immobility during mechanical ventilation increases the risk of skin breakdown. Regular turning improves circulation, reduces prolonged pressure on bony prominences, and prevents pressure injuries. It also supports lung expansion and helps reduce the risk of ventilator-associated pneumonia.

C. Assessing and managing the underlying cause of respiratory failure is a priority because mechanical ventilation is supportive rather than curative. Treating the root cause—such as pneumonia, sepsis, or trauma—improves the likelihood of recovery and successful weaning. Without addressing the underlying condition, respiratory failure may persist or worsen.

D. Providing nutritional support due to increased metabolic demands is essential because mechanically ventilated clients often experience a hypermetabolic state. Adequate nutrition supports immune function, tissue repair, and respiratory muscle strength. Enteral feeding is preferred when possible to maintain gut integrity and reduce infection risk.

E. Administering sedatives and paralytics without assessing pain levels is unsafe and incorrect practice. Sedation and neuromuscular blockade should be carefully titrated based on ongoing assessment of pain, comfort, and ventilator synchrony. Over-sedation can delay weaning, mask complications, and increase the risk of prolonged mechanical ventilation.
