Pharmacodynamics
A medication that blocks a receptor is called this.
Antagonist
This route is slow but safest for conscious patients.
Orally
This organ is primarily responsible for medication metabolism.
Liver
Which of the following is the most common cause of medication errors in prehospital care?
Dose calculation errors
Medication administration should always be followed by reassessment for this.
Adverse effects
This term describes the intended effect of a medication.
Desired effect
This route has the fastest onset of action.
Intravenous
This term describes how the body affects a medication.
Pharmacokinetics
Which “right” of medication administration helps prevent administering medication to the wrong patient?
Right patient
The provider must ensure all equipment used is this before administration.
Sterile
This term describes how strong a drug’s effect is at a given dose.
Potency
This route may be unreliable in patients with poor perfusion.
Intramuscular
The time it takes for a drug to begin working is referred to as this.
Onset of action
Why is accurate documentation critical after medication administration?
It ensures continuity of care
Monitoring is especially critical when medications are administered by this route.
IV route
Giving repeated doses that increase effect is known as this.
Cumulative effect
Endotracheal medication administration is considered unreliable because of this factor.
Variable absorption
This process explains why oral medications act slower than IV medications.
First-pass metabolism
A provider administers a medication via the wrong route but achieves the desired effect. Legally, this is considered:
Monitoring should continue until the medication has reached this phase.
Peak effect
Diuretics primarily act through this alternative mechanism of drug action.
Alteration of cellular environment
Medications administered via inhalation may lose a portion of the dose due to this.
Deposition or loss in the oropharynx
Medications can be affected by patient age, weight, fat content, or this substance in the body.
Protein levels
Which medication error is least likely to be detected without reassessment?
Subtherapeutic dosing
IV medication administration requires monitoring for infiltration or this complication.
Extravasation
