When initiating oxygen therapy for a client with respiratory failure and monitoring their response, which assessment finding would most warrant immediate intervention?

Decreasing oxygen saturation despite oxygen supplementation

Mild increase in respiratory rate

Slight increase in heart rate from baseline

Occasional cough without sputum production

Answer and Explanation

The Correct Answer is A

Respiratory failure occurs when the respiratory system is unable to maintain adequate oxygenation and/or ventilation, leading to hypoxemia and possible organ dysfunction. Oxygen therapy is initiated to improve oxygen delivery to tissues and correct low oxygen levels. However, continuous monitoring is essential because worsening hypoxemia despite oxygen delivery indicates failure of therapy and potential deterioration. Early recognition of inadequate response is critical to prevent respiratory arrest and organ damage.

Rationale:
A. Decreasing oxygen saturation despite oxygen supplementation is the most concerning finding and requires immediate intervention. It indicates that oxygen therapy is not effectively correcting hypoxemia and that the client may be progressing toward severe respiratory failure. This may necessitate escalation of respiratory support, such as noninvasive ventilation or intubation, to prevent further deterioration.

B. A mild increase in respiratory rate is often a compensatory response to hypoxemia and may be expected in respiratory distress. While it should be monitored, it does not immediately indicate failure of oxygen therapy if oxygen saturation is improving or stable. It becomes more concerning only if it progresses or is associated with worsening oxygenation.

C. A slight increase in heart rate from baseline is also a common compensatory mechanism in response to decreased oxygen levels. The cardiovascular system increases heart rate to improve oxygen delivery to tissues. This finding alone does not indicate treatment failure but should be monitored for trends.

D. Occasional cough without sputum production is generally not an urgent finding in this context. It may reflect airway irritation or underlying lung pathology but does not directly indicate worsening oxygenation or respiratory failure. It becomes more significant only if associated with increased work of breathing or declining oxygen saturation.

Correct Answer is C

Explanation

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.

A. Suction the endotracheal tube frequently. B. Position the client at high fowler's. C. Administer a stool softener. D. Perform frequent neurological assessments E. Decrease the noise level in the client's room.

Correct Answer is ["C","D","E"]

Explanation

Increased intracranial pressure (ICP) following a closed-head injury occurs when brain swelling, bleeding, or impaired cerebrospinal fluid dynamics raise pressure within the rigid skull. This can compromise cerebral perfusion and lead to secondary brain injury if not managed promptly. Nursing interventions focus on reducing stimuli that elevate ICP, maintaining adequate cerebral perfusion, and closely monitoring neurological status for early signs of deterioration.

Rationale:
A. Suctioning the endotracheal tube frequently is not recommended because it can significantly increase intracranial pressure. Suctioning stimulates coughing and vagal responses, which elevate intrathoracic pressure and subsequently reduce venous return from the brain. It should only be performed when necessary and with preoxygenation and careful technique.

B. Positioning the client in high Fowler’s position is inappropriate for managing increased ICP. Excessive elevation may reduce cerebral perfusion pressure in some clients. The optimal position is typically head-of-bed elevation around 30 degrees with neutral head alignment to promote venous drainage without compromising blood flow to the brain.

C. Administering a stool softener is important because straining during defecation increases intrathoracic and intracranial pressure through the Valsalva maneuver. Preventing constipation reduces the risk of sudden ICP spikes. Stool softeners help maintain regular, strain-free bowel movements, supporting stable intracranial dynamics.

D. Performing frequent neurological assessments is essential for early detection of changes in intracranial pressure. Monitoring level of consciousness, pupil response, and motor function helps identify deterioration before irreversible brain damage occurs. Timely recognition allows for rapid intervention to prevent further neurological decline.

E. Decreasing the noise level in the client’s room helps reduce external stimulation that can elevate intracranial pressure. Environmental stimuli such as loud noise, bright lights, and excessive activity can increase cerebral metabolic demand. A calm, low-stimulation environment supports brain rest and helps stabilize ICP.
