The nurse is providing discharge teaching to the parents of a 4-year-old with newly diagnosed asthma. An important tool to assess how well the asthma is controlled is:
Peak expiratory flow meter.
Metered dose inhaler with spacer.
Pulse oximetry.
Inhaled steroids.
The Correct Answer is A
Choice A reason: A peak expiratory flow meter is a device that measures how fast the child can exhale air from the lungs. It can help monitor the severity of asthma and the effectiveness of treatment. It can also help identify triggers and prevent asthma attacks.
Choice B reason: A metered dose inhaler with spacer is a device that delivers medication to the lungs. It can help relieve or prevent asthma symptoms, but it does not measure how well the asthma is controlled.
Choice C reason: Pulse oximetry is a device that measures the oxygen saturation of the blood. It can help detect hypoxia, which is a complication of asthma, but it does not measure how well the asthma is controlled.
Choice D reason: Inhaled steroids are a type of medication that reduce inflammation in the airways. They can help prevent asthma attacks and improve lung function, but they do not measure how well the asthma is controlled.

Correct Answer is C
Explanation
Choice A reason: Respiratory tract infection is not a correct answer because it is not a complication of examining the child's throat. It is a possible cause of epiglottitis, which is an inflammation of the epiglottis, the flap that covers the entrance to the trachea.
Choice B reason: Sore throat is not a correct answer because it is not a complication of examining the child's throat. It is a symptom of epiglottitis, along with fever, difficulty swallowing, and drooling.
Choice C reason: Complete airway obstruction is the correct answer because it is a life-threatening complication of examining the child's throat. The tongue depressor can trigger a spasm of the epiglottis, which can block the airway and cause respiratory distress or arrest.
Choice D reason: Inspiratory stridor is not a correct answer because it is not a complication of examining the child's throat. It is a sign of upper airway obstruction, which can occur in epiglottitis, but it is not caused by the tongue depressor.
Correct Answer is A
Explanation
Choice A reason: This is the correct answer because the girl's symptoms indicate that she may have epiglottitis, a life-threatening condition that causes swelling of the epiglottis and obstructs the airway. The nurse should be prepared for a possible intubation or tracheostomy.
Choice B reason: This is not the correct answer because making the girl lie down and rest quietly may worsen her respiratory distress and anxiety. The girl should be allowed to sit in a position of comfort and ease of breathing.
Choice C reason: This is not the correct answer because a thorough neurological assessment is not the priority in this situation. The nurse should focus on the girl's airway, breathing, and circulation.
Choice D reason: This is not the correct answer because auscultating the lungs and preparing for administering oxygen may not be sufficient to manage the girl's airway obstruction. The nurse should also have emergency equipment ready and call for assistance.
