**Core Concept**
The patient has bronchial asthma and is on oral prednisolone and inhaled salbutamol. Asthma management involves controlling inflammation and preventing bronchospasm.

**Why the Correct Answer is Right**
Since the correct answer is not provided, a general approach to managing a chest infection in an asthmatic patient on prednisolone and salbutamol would involve increasing the dose of prednisolone or adding antibiotics if the infection is bacterial, and ensuring the patient uses their salbutamol as needed for bronchospasm.

**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option, a common incorrect choice might involve stopping prednisolone, which is wrong because it could lead to adrenal insufficiency.
**Option B:** Another incorrect choice could be to stop salbutamol, which is incorrect because it is needed for acute relief of bronchospasm.
**Option C:** An incorrect choice might involve adding a new medication without addressing the infection, which is incorrect because it doesn't treat the underlying cause.
**Option D:** An incorrect choice could be to reduce the dose of prednisolone, which is incorrect during an infection as it may worsen asthma control.

**Clinical Pearl / High-Yield Fact**
In patients with asthma on chronic corticosteroids like prednisolone, any intercurrent illness like a chest infection can worsen asthma control, and the steroid dose may need to be increased temporarily.
