Question: 3 mg of atropine injected intravenously causes:
A Decreased intraocular pressure B Diarrhoea C Urinary retention D Tachycardia E Bronchodilation
Answers:
- false
- false
- true
- true
- true
Explanation:
Atropine is a naturally occurring belladonna alkaloid, derived from Atropa Belladonna (the deadly nightshade plant). It can cross the blood-brain barrier and can produce central effects in high doses. A dose of 3 mg produces complete vagal blockade which may manifest as:
- Bronchodilatation and a decrease in bronchial secretions.
- Tachycardia, dysarrythmias
- Decreased tone of the lower oesophageal sphincter.
- Inhibition of Salivary (dry mouth) and gastric secretions with delayed gastric emptying
- Ocular changes
- the normal pupillary reflex is abolished.
- Mydriasis and cycloplegia (photophobia and paralysis of accommodation).
- Minimal effect on intraocular pressure in normal eyes but in patients with narrow-angle glaucoma, dangerous rises in intraocular pressure have been reported.
- CNS changes (the central anticholinergic syndrome)
- Excitation (restlessness, delirium, disorientation and hallucination), followed by generalized CNS depression.
- Urinary retention
- Temperature
- The inhibitory effect on the sweat glands and increase in basal metabolic rate can lead to a rise in body temperature.
