- A. Oropharyngeal airway
- B. Nasopharyngeal airway
- C. Tracheostomy tube
- D. Non-rebreather mask
Explanation: An oropharyngeal airway helps prevent the tongue from obstructing the pharynx in an unconscious patient without a gag reflex.
Correct answer: Oropharyngeal airway- A. Left side-lying position
- B. Right side-lying position
- C. Supine position
- D. Trendelenburg position
Explanation: The healthy lung is placed down because gravity directs more blood flow to that lung, improving ventilation and perfusion matching.
Correct answer: Right side-lying position- A. Increase the oxygen flow immediately
- B. Warm the hand and repeat the reading
- C. Document severe hypoxaemia
- D. Apply a non-rebreather mask
Explanation: Cold peripheral tissue can reduce pulse oximeter accuracy and produce a falsely low reading.
Correct answer: Warm the hand and repeat the reading- A. Nasal cannula
- B. Simple face mask
- C. Non-rebreather mask
- D. Tracheostomy collar
Explanation: A nasal cannula leaves the mouth uncovered, so the patient can communicate and take oral fluids more easily.
Correct answer: Nasal cannula- A. Sterile water supplied for medical use
- B. Tap water from the ward sink
- C. Normal saline from an opened bottle
- D. Boiled water kept at the bedside
Explanation: Sterile water helps humidify oxygen while reducing the risk of introducing microorganisms into the system.
Correct answer: Sterile water supplied for medical use- A. Lay the cylinder loosely beside the patient
- B. Secure the cylinder upright in its holder
- C. Place the cylinder under the patient's bed
- D. Carry the cylinder by its regulator
Explanation: The cylinder should be secured upright so it cannot fall, become damaged or injure someone.
Correct answer: Secure the cylinder upright in its holder47. During tracheostomy care, which finding shows that the tracheostomy ties are secured appropriately?
- A. The ties allow two fingers beneath them
- B. The ties allow four fingers beneath them
- C. The ties press tightly into the neck
- D. The ties are loose enough to slide freely
Explanation: Two fingers should fit between the ties and the neck, providing security without excessive pressure.
Correct answer: The ties allow two fingers beneath them- A. Continue suctioning until secretions clear
- B. Stop suctioning and turn the patient to the side
- C. Instil normal saline through the tracheostomy
- D. Increase the suction pressure and continue
Explanation: Suctioning must stop immediately when gagging and vomiting occur to reduce trauma and aspiration risk.
Correct answer: Stop suctioning and turn the patient to the side- A. It is suitable for an alert patient with a gag reflex
- B. It helps prevent tongue obstruction in an unconscious patient
- C. It is inserted through the nose to reach the trachea
- D. It provides a fixed concentration of inspired oxygen
Explanation: An oropharyngeal airway maintains patency by preventing the tongue from occluding the pharynx in an unconscious patient without a gag…
Correct answer: It helps prevent tongue obstruction in an unconscious patient- A. Continue suctioning to remove remaining secretions
- B. Stop suctioning and provide oxygenation
- C. Increase suction pressure to shorten the procedure
- D. Place the patient flat and leave the catheter in place
Explanation: Bradycardia and pallor may result from hypoxia or vagal stimulation during suctioning.
Correct answer: Stop suctioning and provide oxygenation
