Critical Care Respiratory Questions Questions
Question 1 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 2 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 3 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.
Question 4 of 5
A nurse is reinforcing teaching with the parents of a child who is starting to use a spacer with a metered-dose inhaler (MDI) to treat asthma. Which of the following information should the nurse include in the teaching?
Correct Answer: C
Rationale: The spacer helps to deliver more medication to the lungs by holding the medication in the chamber, allowing the patient to inhale it more slowly and deeply. This results in better deposition of the medication in the lower airways and reduces the amount of medication that is deposited in the mouth and throat.
Question 5 of 5
Which intervention should the nurse prioritize to promote effective airway clearance in a client with impaired oxygenation?
Correct Answer: C
Rationale: Deep breathing and coughing help to mobilize and clear respiratory secretions, promoting effective airway clearance and improved oxygenation.
