The nurse interprets which finding as an early sign of acute respiratory distress syndrome (ARDS) in a client at risk?

Hypoxia not responsive to oxygen therapy

Elevated lactate levels

Metabolic alkalosis

Severe, unexplained electrolyte imbalance

Answer and Explanation

The Correct Answer is A

Choice A reason:

Hypoxia not responsive to oxygen therapy is a hallmark early sign of ARDS. ARDS is characterized by acute onset of hypoxemia that does not improve with supplemental oxygen. This refractory hypoxemia is due to severe inflammation and increased permeability of the alveolar-capillary barrier, leading to pulmonary edema and impaired gas exchange.

Choice B reason:

Elevated lactate levels can indicate tissue hypoxia and metabolic stress, which are concerning findings in critically ill patients. However, elevated lactate is not specific to ARDS and can be seen in various conditions, including sepsis and shock. It is not the primary early indicator of ARDS.

Choice C reason:

Metabolic alkalosis is not typically associated with ARDS. ARDS usually involves respiratory failure, which may lead to respiratory acidosis. Metabolic alkalosis can occur in other conditions, such as excessive loss of gastric acid or diuretic use, but it is not an early sign of ARDS.

Choice D reason:

Severe, unexplained electrolyte imbalance can occur in critically ill patients but is not specific to ARDS. Electrolyte imbalances can result from various factors, including fluid shifts, renal dysfunction, and medication effects. These imbalances do not serve as an early diagnostic indicator of ARDS.

Correct Answer is C

Explanation

Choice A reason:

Assessing the level at which the client has intact sensation is important in the overall management of a spinal cord injury. However, it is not the immediate priority in an emergency setting. Ensuring the client's respiratory function and oxygenation is the first concern to stabilize the patient.

Choice B reason:

Determining the level at which the client has retained mobility is part of the assessment of a spinal cord injury but is secondary to monitoring and ensuring adequate respiratory effort and oxygen saturation. Mobility can be evaluated once the patient's vital signs are stable.

Choice C reason:

Monitoring respiratory effort and oxygen saturation level is the priority nursing action for a client with a spinal cord injury at the C3 to C4 level. Injuries at this level can impair the diaphragm and other muscles essential for breathing. Ensuring that the patient has adequate respiratory function and oxygenation is critical to prevent respiratory failure.

Choice D reason:

Checking blood pressure and pulse for signs of spinal shock is important, but the immediate priority is to ensure that the patient is breathing effectively and has sufficient oxygen saturation. Respiratory compromise can occur quickly with high-level spinal cord injuries, making it the most urgent concern.

A. A 72-year-old client with a brain tumor, GCS of 5 and decerebrate posturing. B. A 24-year-old client after a motor vehicle accident with a Glasgow Coma Scale (GCS) of 3 and no activity on electroencephalogram. C. A 68-year-old male admitted with a massive stroke and GCS of 6. D. A 50-year-old female client after a motor vehicle accident and surgical evacuation of an epidural hematoma, Glasgow Coma Scale 12.

Correct Answer is B

Explanation

Choice A reason:

A 72-year-old client with a brain tumor, GCS of 5, and decerebrate posturing may not be an ideal candidate for organ donation due to age and underlying cancer, which can affect organ viability.

Choice B reason:

A 24-year-old client after a motor vehicle accident with a GCS of 3 and no activity on electroencephalogram is a prime candidate for organ donation. The lack of brain activity indicates brain death, and the patient's young age and otherwise healthy organs make them suitable for transplantation.

Choice C reason:

A 68-year-old male with a massive stroke and GCS of 6 has significant neurological impairment but is not necessarily brain dead. Further evaluation would be required, but this patient may not meet the criteria for brain death necessary for organ donation.

Choice D reason:

A 50-year-old female with a GCS of 12 after surgical evacuation of an epidural hematoma is not an ideal candidate for organ donation at this time as they have a higher level of consciousness and potential for recovery.
