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 A

Explanation

Choice A reason:

The patient coughing is the most likely cause of the high pressure alarm on a mechanical ventilator. Coughing can increase airway resistance and pressure, triggering the alarm. This is a common occurrence and should be addressed by assessing the patient's need for suctioning or other interventions to relieve the cough.

Choice B reason:

An endotracheal tube (ETT) cuff leak would typically cause a low pressure alarm, not a high pressure alarm. A cuff leak results in a loss of pressure within the ventilator circuit, leading to insufficient ventilation and a different alarm response.

Choice C reason:

If the ventilator tubing becomes disconnected, it would result in a low pressure alarm due to the loss of circuit integrity. A disconnection is a serious issue that needs immediate correction but does not cause high pressure alarms.

Choice D reason:

The patient's complaint of a headache does not directly relate to a high pressure alarm on the ventilator. While patient discomfort should always be addressed, it is not the most likely cause of the alarm in this scenario.

A. Palpate the bladder for distention. B. Initiate oxygen via a nasal cannula. C. Place the patient in a supine position. D. Administer a prescribed beta-blocker.

Correct Answer is A

Explanation

Choice A reason:

Palpating the bladder for distention is the first action the nurse should take. The patient's symptoms suggest autonomic dysreflexia, a condition that can be triggered by bladder distention. Relieving the distention can help resolve the hypertensive crisis.

Choice B reason:

Initiating oxygen via a nasal cannula may be necessary if the patient is experiencing respiratory distress, but it is not the primary intervention for autonomic dysreflexia. The focus should be on identifying and resolving the triggering cause.

Choice C reason:

Placing the patient in a supine position is contraindicated in autonomic dysreflexia as it can worsen the condition by further increasing blood pressure. The patient should be positioned upright if tolerated.

Choice D reason:

Administering a prescribed beta-blocker may help lower blood pressure, but it is not the first action. The underlying cause of autonomic dysreflexia must be addressed to prevent recurrence.
