A mother arrives at the hospital emergency department with her child, in whom a diagnosis of epiglottitis is documented. Which prescription, if written by the health care provider, should the nurse question?
Obtain a throat culture.
Administer humidified oxygen
Administer acetaminophen for fever.
Obtain axillary temperatures.
The Correct Answer is A
A. Obtain a throat culture: Attempting to visualize or culture the throat in a child with epiglottitis is dangerous and can trigger laryngospasm, leading to sudden airway obstruction. Any procedure that manipulates the airway should be avoided.
B. Administer humidified oxygen: Humidified oxygen helps ease breathing and reduce airway irritation. It is a supportive measure that can be safely administered without disturbing the airway and is commonly used in cases of respiratory distress such as epiglottitis.
C. Administer acetaminophen for fever: Fever is a common symptom of epiglottitis, and acetaminophen can be safely used to reduce temperature and increase comfort. It poses no risk to airway integrity and supports symptomatic relief.
D. Obtain axillary temperatures: Using the axillary route avoids disturbing the oral cavity, making it a safe and appropriate method for monitoring temperature in a child with suspected or confirmed epiglottitis. It minimizes the risk of triggering airway complications.

Correct Answer is B
Explanation
A. "We will do a simple blood test.A blood test may show signs of infection, such as elevated white blood cells, but it cannot confirm RSV. It is not a specific or reliable method for diagnosing respiratory syncytial virus in infants.
B. "We will swab your child’s nose and send the specimen for testing.Nasopharyngeal swabs are commonly used to detect RSV using antigen detection or polymerase chain reaction (PCR) testing. The procedure is non-invasive, and highly specific for diagnosing RSV.
C. "We will have to sedate your child and do a CT scan of his chest."CT scans are not used to diagnose RSV and carry unnecessary risk, especially with sedation in infants. Imaging is reserved for complicated or atypical cases and does not confirm viral etiology.
D. “There is no specific test for RSV."There are several reliable tests available for detecting RSV, including rapid antigen tests and PCR from nasal secretions. Accurate testing is important for confirming diagnosis and preventing transmission.
Correct Answer is A
Explanation
A. Vitamin K:Vitamin K is the antidote for warfarin overdose. Warfarin inhibits vitamin K-dependent clotting factors, and administering vitamin K reverses this effect by promoting the synthesis of clotting factors to control bleeding.
B. Magnesium sulfate:Magnesium sulfate is used to treat conditions such as torsades de pointes and eclampsia but has no role in reversing the anticoagulant effects of warfarin. It does not impact coagulation pathways or vitamin K levels.
C. Flumazenil:Flumazenil is an antidote for benzodiazepine overdose. It acts by antagonizing the effects of drugs like diazepam and lorazepam but has no effect on warfarin or anticoagulation reversal.
D. Protamine sulfate:Protamine sulfate is the antidote for heparin and low-molecular-weight heparin overdose, not warfarin. It neutralizes heparin's anticoagulant properties but does not interact with vitamin K or affect warfarin action.
