Critical Care Respiratory Questions Questions
Question 1 of 5
Which assessment finding indicates ineffective oxygenation?
Correct Answer: C
Rationale: Cyanosis (bluish skin) indicates poor oxygenation due to low oxygen saturation, unlike clear lung sounds, normal pulse oximetry, or stable blood pressure.
Question 2 of 5
A patient with a pulse oximetry reading of 88% requires which intervention?
Correct Answer: B
Rationale: A pulse oximetry of 88% indicates hypoxemia (normal is 95-100%). Administering oxygen is the priority to correct low oxygen levels, over coughing, repositioning, or checking temperature.
Question 3 of 5
A nurse is caring for a patient with a tracheostomy. What is the priority intervention?
Correct Answer: C
Rationale: Suctioning as needed maintains airway patency in a tracheostomy, ensuring oxygenation, taking priority over monitoring, cleaning, or dressing changes.
Question 4 of 5
A nurse is teaching a patient with COPD about energy conservation. Which strategy is best?
Correct Answer: B
Rationale: Frequent rest breaks conserve energy in COPD, reducing oxygen demand, unlike vigorous exercise, avoiding breathing exercises, or fluid restriction.
Question 5 of 5
Which time would be ideal for the LPN/LVN to collect a sputum specimen?
Correct Answer: B
Rationale: Morning is considered the ideal time for collecting a sputum specimen. Overnight, mucus accumulates in the respiratory tract because the patient is less active and not clearing their throat or coughing as much. This means that the mucus is more concentrated and has had time to build up, providing a more substantial and representative sample of what is in the lungs.
