Which statement best defines an agonist’s action at receptors?
Binds and activates, then blocks receptors
Binds and activates receptors causing effects
Binds receptors but reverses all effects
Destroys the receptor, no effect occurs
Which clinical sign is most consistent with severe carbon monoxide poisoning?
Peripheral cyanosis with dark venous blood
Pupils fixed and dilated without hypoxia
Venous blood appears unusually bright
Bradycardia with normal oxygen saturation
Which medication class best treats opioid or benzodiazepine overdose?
Antagonists targeting those receptors
Antiplatelets for thrombus reduction

When teaching IVIO dosing via endotracheal tube, what is typical dosing guidance?
Half the IVIO dose due to absorption
Never use ET for emergency drugs
Two to five times the IVIO dose
Use same dose as IVIO in most cases
What pharmacokinetic change is common in elderly patients?
Increased plasma protein binding
Decreased renal clearance and sensitivity
Increased enzyme activity and plasma levels
Greater volume of distribution for water drugs
Provide the standard sublingual nitroglycerin dosing convention.
SL route, 0.4 mg, every 5 minutes, up to 3 doses
PO route, 0.4 mg, every hour, up to 2 doses
SL route, 0.2 mg, every 10 minutes, up to 4 doses
IM route, 0.4 mg, once, repeat as needed
Which preoperative safety principle takes priority?
Verify postoperative labs before anesthesia
Document only after response
Refuse surgical orders first
Patient safety always comes first
Which initial ED assessment mnemonic emphasizes airway, breathing, circulation?
SOAP notes then vitals
Patient safety: indication, response, documentation
Classic five rights of meds
Standard mnemonic adds reason and response
Which autonomic pathway causes bradycardia and increased GI motility?
Sympathetic nervous system
Enteric inhibitory pathway
Parasympathetic nervous system
Somatic motor neurons
Dopamine has dose-dependent effects. Which pairing reflects low-dose action?
Vasoconstriction via alpha-1
Renal vasodilation via D1
Bronchodilation via beta-2
AV block via M2 receptors
Which is a correct glucagon reconstitution fact?
Usually reconstituted with diluent before use
Typically supplied as liquid ready to inject
Never requires mixing for IV administration
Given only orally when patient swallows
How is hydroxocobalamin supplied for IV administration?
Activated charcoal suspension
Solid tablet for infusion
Lyophilized powder to reconstitute
Pre-mixed oral syrup formulation
What combination reduces reflex tachycardia and AV conduction in hypertension therapy?
DHP CCBs with beta-agonists
Alpha-2 agonists with nitrates
ACE inhibitors with diuretics
Non-DHP CCBs with beta-blockers

Lidocaine 1% as carrier fluid
Sterile water 2 mL without ventilating
10 mL normal saline and ventilate
Ipratropium produces bronchodilation primarily by which mechanism?
Blocking muscarinic receptors
Stimulating beta‑2 receptors
Releasing histamine from mast cells
Blocking sodium channels in bronchi
Which pairing correctly matches agent and primary receptor effect?
Dobutamine
Beta‑1 agonist increases contractility
Atropine
Muscarinic antagonist increases heart rate
Phenylephrine
Alpha‑1 agonist raises vascular tone
Metoprolol
Beta‑1 antagonist reduces heart rate
