Which of the following complications is associated with mechanical ventilation? Select all that apply

Stress ulcers

Immunosuppression

Hypotension

Pulmonary emboli

Barotrauma

Pneumonia

Answer and Explanation

Correct Answer : A,C,E,F

A. Critically ill clients on mechanical ventilation are at increased risk of stress-related mucosal damage, which can lead to gastric or duodenal ulcers due to physiologic stress, reduced perfusion, and acid hypersecretion.

B. Mechanical ventilation does not directly suppress the immune system. Immunosuppression may occur due to underlying illness, medications, or critical illness, but it is not a direct complication of the ventilator itself.

C. Positive pressure ventilation can increase intrathoracic pressure, reducing venous return to the heart, which may lead to decreased cardiac output and hypotension, especially in patients with hypovolemia.

D. Mechanical ventilation does not directly cause pulmonary emboli. Risk factors for emboli include immobility, hypercoagulable states, or recent surgery, not the ventilator itself.

E. Mechanical ventilation can cause barotrauma, which is damage to the alveoli or lungs due to excessive pressure or volume, potentially leading to pneumothorax, subcutaneous emphysema, or pneumomediastinum.

F. Mechanical ventilation increases the risk of ventilator-associated pneumonia (VAP) due to impaired airway defense, colonization of the endotracheal tube, and aspiration of secretions.

Correct Answer is B

Explanation

A. While ABG analysis is important for evaluating oxygenation, ventilation, and acid-base status, it is diagnostic rather than therapeutic. Performing an ABG does not correct the low oxygen saturationor prevent further tissue hypoxia. Therefore, it is a secondary action after initiating oxygen.

B. Oxygen therapy directly addresses the immediate threat of hypoxemia, increasing oxygen delivery to vital organs and tissues. Prompt administration of supplemental oxygen is critical to prevent further deterioration of mental status, organ perfusion, and cardiac function. In a client with sepsis or septic shock, improving oxygenation is a top prioritybefore or during transfer to a higher level of care like the ICU.

C. Treating fever is supportive care but does not resolve hypoxemia or hypotension, which are life-threatening. Fever management is important for comfort and infection control but is secondary to stabilizing oxygenation and perfusion.

D. Continuous cardiac monitoring is important for detecting arrhythmias associated with sepsis or hypoxemia, but it does not intervene in the immediate oxygen deficit. Monitoring alone cannot prevent organ dysfunction caused by low oxygen saturation.

A. Fever B. Headache C. Suspected poisoning D. Chest pain E. Abdominal pain

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

Explanation

A. While fever is a common symptom, it is usually a secondary complaint or part of an underlying conditionrather than a primary reason for emergency department (ED) visits. Patients with fever alone often seek primary care unless it is associated with severe infection or sepsis.

B. Headaches are common in the general population, but only severe or acute-onset headachesare typical ED presentations. Routine or mild headaches are usually managed in outpatient settings.

C. Poisonings, overdoses, and exposure to toxic substances are urgent issues that require immediate assessment and interventionin the ED. These cases frequently demand rapid evaluation, monitoring, and sometimes antidote administration.

D. Chest pain is a common and critical complaint in the EDbecause it may indicate life-threatening conditions such as myocardial infarction, pulmonary embolism, or aortic dissection. It is prioritized for immediate assessment and intervention.

E. Abdominal pain is one of the most frequent reasons for ED visits, ranging from minor issues to surgical emergencies such as appendicitis, bowel obstruction, or perforated ulcers. Prompt evaluation is essential to identify life-threatening conditions.
