CCP Patient Counseling & Safety 2 — Questions and Answers
Question 1: A patient on warfarin reports starting a new fish oil supplement (2g/day). What is the most appropriate counseling action?
- Advise discontinuation immediately without consulting the prescriber
- Inform the patient that fish oil has no interaction with warfarin
- Counsel the patient to notify their prescriber and monitor INR more closely (Correct answer)
- Recommend switching to a COX-2 inhibitor instead
Correct answer: Counsel the patient to notify their prescriber and monitor INR more closely
Fish oil at higher doses can potentiate warfarin's anticoagulant effect, so closer INR monitoring and prescriber notification are warranted.
Question 2: During a medication review, a consultant pharmacist identifies that an elderly patient is taking diphenhydramine nightly for sleep. According to the Beers Criteria, what is the primary concern?
- Risk of dependence and withdrawal
- Anticholinergic effects including cognitive impairment and urinary retention (Correct answer)
- QT prolongation leading to arrhythmia
- Serotonin syndrome risk
Correct answer: Anticholinergic effects including cognitive impairment and urinary retention
Diphenhydramine is a Beers Criteria drug in older adults due to strong anticholinergic properties that increase risk of confusion, falls, and urinary retention.
Question 3: A patient with dysphagia is prescribed an extended-release potassium chloride tablet. What is the safest counseling recommendation?
- Crush the tablet and mix with applesauce
- Dissolve the tablet in 8 oz of warm water before taking
- Consult the prescriber about switching to a liquid or immediate-release formulation (Correct answer)
- Take the tablet with a full glass of milk to coat the esophagus
Correct answer: Consult the prescriber about switching to a liquid or immediate-release formulation
Extended-release potassium tablets must not be crushed because doing so can cause GI ulceration; a liquid or alternative formulation is safer for dysphagia patients.
Question 4: Which technique best assesses patient comprehension during medication counseling?
- Ask the patient 'Do you understand?'
- Provide a written handout and assume comprehension
- Use the teach-back method by asking the patient to explain the information back (Correct answer)
- Read the package insert aloud to the patient
Correct answer: Use the teach-back method by asking the patient to explain the information back
The teach-back method requires patients to repeat information in their own words, validating true understanding rather than passive acknowledgment.
Question 5: A nursing home resident on metformin develops acute kidney injury. What is the primary safety concern the consultant pharmacist should address?
- Hypoglycemia from accumulation of metformin
- Lactic acidosis due to metformin accumulation in renal impairment (Correct answer)
- Peripheral neuropathy worsening
- Risk of ketoacidosis
Correct answer: Lactic acidosis due to metformin accumulation in renal impairment
Metformin accumulates when renal clearance is reduced, increasing the risk of potentially fatal lactic acidosis.
Question 6: A patient is counseled about taking alendronate for osteoporosis. Which instruction is MOST critical for safety?
- Take with a full glass of orange juice for best absorption
- Take at bedtime to reduce GI upset
- Remain upright for at least 30 minutes after taking and take with plain water only (Correct answer)
- Crush the tablet if swallowing is difficult
Correct answer: Remain upright for at least 30 minutes after taking and take with plain water only
Bisphosphonates like alendronate can cause esophageal ulceration if the patient lies down after dosing; patients must stay upright for at least 30 minutes.
Question 7: A patient using a metered-dose inhaler (MDI) without a spacer reports poor asthma control. What counseling intervention is most appropriate?
- Increase the number of puffs per dose without prescriber guidance
- Recommend switching entirely to oral corticosteroids
- Assess and correct the patient's MDI technique, including coordination of actuation and inhalation (Correct answer)
- Advise the patient to take the inhaler right before bed only
Correct answer: Assess and correct the patient's MDI technique, including coordination of actuation and inhalation
Poor inhaler technique is a leading cause of suboptimal asthma control, and correcting technique—including adding a spacer—significantly improves drug delivery.
