A nurse expects which of the following patients to be in Respiratory Acidosis?

Choice A rationale

Patient self-extubation would typically trigger a low-pressure alarm, not a high-pressure alarm, because the ventilator circuit would no longer be connected to the patient's airway, resulting in a sudden drop in airway pressure and a loss of positive pressure ventilation.

Choice B rationale

Disconnection of the tubes, similar to self-extubation, would lead to a low-pressure alarm due to the loss of a closed circuit. The ventilator would detect a rapid decrease in pressure within the system as air escapes, indicating a leak or complete disconnection.

Choice C rationale

Tube displacement, particularly if the endotracheal tube is pushed deeper into the bronchus or becomes kinked, increases airway resistance. This heightened resistance requires the ventilator to exert more pressure to deliver the set tidal volume, thus triggering a high-pressure alarm.

Choice D rationale

The patient biting the endotracheal (ET) tube creates an occlusion within the airway, significantly increasing airway resistance. This increased resistance makes it harder for the ventilator to deliver breaths, leading to a rapid rise in peak inspiratory pressure and activating the high-pressure alarm.

Choice A rationale

The absence of lung sounds on the right side would indicate a problem in the right lung, such as a right-sided pneumothorax or severe atelectasis of the right lung. Given the scenario specifies a left-sided pneumothorax, the primary assessment findings would be localized to the affected (left) side, not the contralateral side.

Choice B rationale

A left-sided pneumothorax, characterized by air accumulating in the pleural space on the left side, will lead to collapse of the left lung. This collapse will result in an absence of breath sounds and diminished or absent chest rise on the affected (left) side due to the lung's inability to inflate and participate in ventilation.

Choice C rationale

Hypertension (elevated blood pressure) and bradypnea (slow respiratory rate) are not typical primary findings in an acute pneumothorax. While a pneumothorax can cause respiratory distress, it often leads to tachypnea (increased respiratory rate) as the body attempts to compensate for reduced lung function and potentially hypotension due to impaired venous return.

Choice D rationale

Lack of chest rise bilaterally would indicate a more generalized respiratory issue, such as severe bilateral atelectasis, bilateral mainstem bronchus obstruction, or a severe neurological impairment affecting respiratory drive. In a unilateral pneumothorax, the contralateral lung would typically still demonstrate some degree of chest rise, although it might be diminished. .
