An infant with a continuous inspiratory and expiratory stridor may be exhibiting symptoms of:
hypocalcemia.
increased intracranial pressure.
an upper airway obstruction.
vocal cord paralysis.
The Correct Answer is C
Rationale:
A. Hypocalcemia typically presents with neuromuscular irritability, such as tetany or seizures, not stridor.
B. Increased intracranial pressure manifests with headache, vomiting, bulging fontanel, and altered consciousness, not continuous stridor.
C. Continuous inspiratory and expiratory stridor in an infant is a hallmark sign of an upper airway obstruction, which may be caused by congenital anomalies (e.g., laryngomalacia, tracheomalacia), foreign body, or airway mass. Prompt evaluation is necessary to assess airway patency and prevent respiratory compromise.
D. Vocal cord paralysis often causes a weak, hoarse cry or intermittent stridor but usually does not result in continuous inspiratory and expiratory stridor.

Explanation
Rationale:
A. NSAIDs may help with pain but do not treat the underlying inflammation of the facial nerve in Bell’s palsy.
B. Third-generation cephalosporins are antibiotics and are not indicated unless there is a concurrent bacterial infection.
C. Gabapentin is used for neuropathic pain but is not first-line therapy for Bell’s palsy.
