The question does not tell you what to round to? I rounded 2.27272727 to 2.3, in the actual PSA do you think this would be allowed?

Chapter
#### Monitoring

The BNF advises to monitor lung function (in patients with a history of obstructive airway disease).

#### Overdoses

Overdosages with beta-blockers may cause cardiac effects such as bradycardia, hypotension, syncope, conduction abnormalities, and heart failure. Bradycardia is the most common arrhythmia, but some beta-blockers may induce ventricular tachyarrhythmias secondary to prolongation of QT interval (e.g. sotalol) or QRS duration (e.g. propranolol).
Non-cardiovascular effects include central nervous system effects (including drowsiness, confusion, convulsions, hallucinations, and in severe cases coma), respiratory depression, and bronchospasm.

Management
 - Airway protection 
 - Activated charcoal within 1 hour
 - IV Fluids
 
IV glucagon is the first-line management.
 
For symptomatic bradycardia, IV atropine may be used.

Dose = 7.5 mg/kg
Weight = 7.5kg
Amount of clarithromycin needed
= 7.5 mg/kg x 7.5kg = 56.25mg
Volume of clarithromycin solution
= 56.25mg x 5mL/125mg = 2.25mL

A 6-month old boy is brought to the emergency department by his mother because he was very unwell and was noted to have blisters across both sides of his cheeks. He was subsequently diagnosed with erysipelas and was to be started on clarithromycin 7.5mg/kg PO twice daily due to a previous penicillin allergy. Weight 7.5kg.


Clarithromycin is available as 125mg/5mL oral suspension

What volume (mL) of clarithromycin oral solution should he be given at each dose?
