What is a possible complication of using assist control ventilation mode on a mechanical ventilator?
Hyperventilation
Hypercapnia
Tachycardia
Fever
The Correct Answer is A
A. Hyperventilation: In assist-control (AC) ventilation, every patient-initiated breath is supported with a preset tidal volume. If the patient breathes rapidly, the ventilator will deliver the same volume for each breath, which can result in excessive minute ventilation and respiratory alkalosis due to hyperventilation.
B. Hypercapnia: Hypercapnia is unlikely in AC mode if the ventilator is set correctly, as the preset tidal volume ensures adequate CO2 elimination. Hypercapnia usually occurs if ventilation is inadequate or there is severe underlying lung pathology.
C. Tachycardia: Tachycardia is not a direct complication of AC ventilation; it may occur secondary to hypoxemia, anxiety, or underlying illness but is not caused by the ventilator mode itself.
D. Fever: Fever is unrelated to ventilator mode. It may indicate infection or inflammation but is not a complication of assist-control ventilation.

Correct Answer is C
Explanation
A. Turning/repositioning patient: While repositioning is important for overall patient care and to prevent pressure injuries, it is not specific to tracheostomy management and does not directly maintain airway patency.
B. Bathing patient: Bathing is part of routine hygiene care but does not relate directly to the function or safety of the tracheostomy tube.
C. Assessing patency of tracheostomy tube: Ensuring the tracheostomy tube is patent is critical to maintaining a clear airway, preventing obstruction, and ensuring adequate ventilation. Regular assessment includes checking for secretions, tube displacement, and airway obstruction.
D. Providing bag mask ventilation to patient each shift: Bag-mask ventilation is only indicated in emergencies when the patient is not ventilating adequately. Routine ventilation is not part of standard tracheostomy care.
Correct Answer is C
Explanation
A. Antihypertensive and anticoagulant medication: These medications are not indicated for rapid sequence intubation. Their primary purposes—blood pressure control and prevention of clotting—do not facilitate airway management.
B. A short acting bronchodilator: Bronchodilators help open the airways in obstructive pulmonary conditions but do not provide sedation, pain relief, or muscle relaxation necessary for intubation.
C. A sedative, analgesic and a paralytic drug: Rapid sequence intubation requires a combination of medications to induce unconsciousness (sedative), relieve pain (analgesic), and produce muscle relaxation (paralytic) to allow safe and efficient endotracheal tube placement while minimizing patient movement and airway trauma.
D. An antibiotic: Antibiotics are not part of the RSI protocol. They are used to treat or prevent infections but do not facilitate intubation or airway management.
