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 B

Explanation

Choice A reason:

Providing small doses of opioid analgesia is important for pain management, but it is not the highest priority in a patient with a closed head injury on mechanical ventilation. Pain control should be balanced with the need to monitor neurological status.

Choice B reason:

Maintaining pCO2 of 35-45 is critical for patients with a closed head injury on mechanical ventilation. Proper pCO2 levels help manage intracranial pressure (ICP) and prevent secondary brain injury. Hyperventilation to lower pCO2 can reduce ICP but must be carefully controlled to avoid cerebral ischemia.

Choice C reason:

Administering an anti-anxiety agent can help manage agitation and anxiety, but it is not the highest priority. Sedation must be used cautiously in head injury patients to avoid masking changes in neurological status.

Choice D reason:

Monitoring blood pressure every four hours is necessary for overall patient care, but continuous monitoring and immediate interventions are more critical in managing intracranial pressure and preventing secondary brain injury.

A. Loss of consciousness greater than 30 minutes following injury. B. Lucid intervals followed by momentary unconsciousness. C. Memory loss of the prior day's activities. D. Amnesia of the injury event.

Correct Answer is B

Explanation

Choice A reason:

Loss of consciousness greater than 30 minutes following injury can occur in various types of head injuries but is not specific to epidural hematomas.

Choice B reason:

Lucid intervals followed by momentary unconsciousness are characteristic of epidural hematomas. Patients with epidural hematomas often experience a period of lucidity following the initial loss of consciousness, followed by a rapid decline in mental status as the hematoma enlarges and increases intracranial pressure.

Choice C reason:

Memory loss of the prior day's activities can occur with various head injuries but is not specific to epidural hematomas.

Choice D reason:

Amnesia of the injury event is common in head injuries but is not specific to epidural hematomas. The hallmark of epidural hematomas is the pattern of lucid intervals followed by rapid deterioration.
