The nurse is assessing a child with acute epiglottitis.
Examining the child’s throat by using a tongue depressor might precipitate which symptom or condition?
Inspiratory stridor
Complete obstruction
Sore throat
Respiratory tract infection
The Correct Answer is B
If a child has acute epiglottitis, examination of the throat may cause complete obstruction and should be performed only when immediate intubation can take place.
This is because the inflamed epiglottis can block the airway and cause respiratory distress or failure.
Choice A is wrong because inspiratory stridor is a sign of upper airway obstruction that is aggravated when a child with epiglottitis is supine.
It is not caused by examining the throat with a tongue depressor.
Choice C is wrong because sore throat and pain on swallowing are early signs of epiglottitis, not precipitated by examining the throat with a tongue depressor.
Choice D is wrong because respiratory tract infection is the cause of epiglottitis, not a symptom or condition that is precipitated by examining the throat with a tongue depressor.
Epiglottitis is caused by H. influenzae in the respiratory tract.

Correct Answer is C
Explanation
The patient is showing signs of magnesium toxicity, such as respiratory depression, hyporeflexia, and flushing.
Magnesium sulfate is a high-alert medication that can cause serious adverse effects if not monitored closely.
The nurse should stop the infusion immediately and notify the provider.
Choice A is wrong because calling for a stat magnesium sulfate level will not address the immediate problem of toxicity.
The nurse should act quickly to prevent further complications.
Choice B is wrong because administering oxygen will not reverse the effects of magnesium toxicity.
Oxygen may be helpful for respiratory distress, but it will not correct the underlying cause.
Choice D is wrong because hydralazine is an antihypertensive medication that lowers blood pressure.
The patient’s blood pressure is already within the normal range for a pregnant woman with preeclampsia (140-160/90-110 mm Hg).
Hydralazine may cause hypotension and fetal distress.
