Cholinergic agonists are also known as parasympathomimetics because they:

• Block acetylcholine receptors throughout the body

• Mimic the effects of parasympathetic nervous system activation

• Stimulate the sympathetic nervous system directly

• Inhibit acetylcholinesterase enzyme activity

Which of the following is a direct-acting cholinergic agonist specifically indicated for neurogenic bladder atony?

• Neostigmine

• Bethanechol

• Edrophonium

• Pyridostigmine

A patient receiving pilocarpine eye drops for glaucoma should be monitored for which adverse effect?

• Mydriasis (pupil dilation)

• Decreased salivation

• Miosis (pupil constriction)

• Increased intraocular pressure

Indirect-acting cholinergic agonists work by:

• Directly stimulating acetylcholine receptors

• Preventing the breakdown of acetylcholine by acetylcholinesterase

• Blocking muscarinic receptors selectively

• Enhancing dopamine transmission in the brain

Which medication should be kept readily available as an antidote for cholinergic drug overdose?

• Epinephrine

• Naloxone

• Atropine

• Flumazenil

A contraindication for using direct-acting cholinergic agonists would be:

• Myasthenia gravis

• Urinary retention

• Bradycardia with hypotension

• Alzheimer's disease

Anticholinergic drugs like atropine work by:

• Enhancing acetylcholine synthesis

• Competitively blocking muscarinic cholinergic receptors

• Inhibiting acetylcholinesterase enzyme

• Stimulating nicotinic receptors selectively

Which of the following is NOT an expected effect of anticholinergic medications?

• Decreased gastrointestinal motility

• Pupil constriction (miosis)

• Decreased salivary secretions

• Increased heart rate

The anterior pituitary gland secretes all of the following hormones EXCEPT:

• Growth hormone (GH)

• Thyroid-stimulating hormone (TSH)

• Antidiuretic hormone (ADH)

• Adrenocorticotropic hormone (ACTH)

Somatropin is indicated for treatment of:

• Acromegaly in adults

• Growth hormone deficiency in children

• Diabetes insipidus

• Hyperthyroidism
