What is drug tolerance?
Answer: The body's reduced response to a drug after repeated exposure, requiring higher doses for the same effect
Drug tolerance occurs when the body adapts to a medication through repeated exposure, reducing its effect and requiring higher doses to achieve the same result.
Which residents are at highest risk for adverse drug reactions?
Answer: Elderly residents taking multiple medications with multiple medical conditions
Elderly residents face the highest ADR risk due to polypharmacy, age-related changes in drug metabolism, reduced kidney and liver function, and multiple comorbidities.
A resident taking a loop diuretic complains of muscle cramps and weakness. This may indicate:
Answer: Electrolyte imbalance, particularly low potassium (hypokalemia)
Loop diuretics like furosemide can deplete potassium, causing hypokalemia, which manifests as muscle cramps, weakness, and potentially dangerous cardiac arrhythmias.
What is a drug-drug interaction?
Answer: When one medication alters the effectiveness, metabolism, or toxicity of another medication
A drug-drug interaction occurs when one medication alters how another medication works, either increasing its effect, reducing its effect, or causing new harmful effects.
How should a medication technician respond when a resident refuses their medication?
Answer: Document the refusal, report to the nurse, and respect the resident's right to refuse
Residents have a legal and ethical right to refuse medications; refusals must always be documented on the MAR and reported to the nurse for follow-up.
Which of the following is a clinically significant drug-food interaction?
Answer: Taking warfarin while consuming large amounts of leafy green vegetables daily
Vitamin K found in leafy greens can significantly reduce warfarin's anticoagulant effect, making consistent dietary vitamin K intake critical for stable INR levels.
