CCP Patient Counseling & Safety 3 — Questions and Answers
Question 1: A patient prescribed lithium asks if they can use ibuprofen for knee pain. What is the most important counseling point?
- Ibuprofen is safe in low doses with lithium
- NSAIDs can increase lithium levels and lead to toxicity (Correct answer)
- Ibuprofen decreases lithium levels, reducing its effectiveness
- The combination is safe as long as the patient stays well-hydrated
Correct answer: NSAIDs can increase lithium levels and lead to toxicity
NSAIDs reduce renal prostaglandin synthesis, decreasing lithium excretion and raising serum lithium levels to potentially toxic concentrations.
Question 2: When counseling a patient about clonidine patch placement for hypertension, which instruction is most important?
- Apply to the same skin site each week to maximize absorption
- Rotate application sites on hairless skin and dispose of used patches safely (Correct answer)
- Apply to the chest only to ensure consistent drug delivery
- Remove the patch whenever blood pressure is at goal
Correct answer: Rotate application sites on hairless skin and dispose of used patches safely
Rotating sites prevents local skin irritation, and used clonidine patches still contain significant drug amounts and must be folded sticky-side-in before disposal to prevent accidental exposure.
Question 3: A patient with heart failure is started on spironolactone. What dietary counseling is most essential?
- Increase potassium-rich foods to maintain electrolyte balance
- Avoid potassium-rich foods and potassium supplements due to hyperkalemia risk (Correct answer)
- Restrict sodium but increase fluid intake
- Increase magnesium-rich foods to prevent arrhythmia
Correct answer: Avoid potassium-rich foods and potassium supplements due to hyperkalemia risk
Spironolactone is a potassium-sparing diuretic; adding potassium-rich foods or supplements significantly raises hyperkalemia risk, which can cause life-threatening arrhythmias.
Question 4: Which of the following best describes medication reconciliation in a long-term care setting?
- Discontinuing all pre-admission medications and restarting only essential ones
- Comparing a patient's current medication orders to all medications the patient was taking prior to a transition of care (Correct answer)
- Reviewing only high-alert medications at admission
- Updating the pharmacy profile once quarterly
Correct answer: Comparing a patient's current medication orders to all medications the patient was taking prior to a transition of care
Medication reconciliation is the process of comparing medication orders to all medications a patient was taking before a transition to identify and resolve discrepancies.
Question 5: A consultant pharmacist counsels a patient newly prescribed tacrolimus after a kidney transplant. Which counseling point is most critical for safety?
- Tacrolimus can be taken with grapefruit juice to improve taste
- Avoid grapefruit and grapefruit juice because they significantly increase tacrolimus levels (Correct answer)
- Take tacrolimus with food to reduce nephrotoxicity
- Skip doses if mild GI upset occurs
Correct answer: Avoid grapefruit and grapefruit juice because they significantly increase tacrolimus levels
Grapefruit inhibits CYP3A4, the primary enzyme metabolizing tacrolimus, causing dangerous drug level increases and toxicity risk.
Question 6: A patient on a monoamine oxidase inhibitor (MAOI) asks about using pseudoephedrine for nasal congestion. What is the appropriate response?
- Low doses of pseudoephedrine are safe with MAOIs
- Pseudoephedrine is contraindicated with MAOIs due to risk of hypertensive crisis (Correct answer)
- Recommend combining pseudoephedrine with a beta-blocker for safety
- Allow the combination only if the MAOI has been taken for more than 2 weeks
Correct answer: Pseudoephedrine is contraindicated with MAOIs due to risk of hypertensive crisis
MAOIs potentiate the effects of sympathomimetics like pseudoephedrine, causing potentially fatal hypertensive crisis.
Question 7: A long-term care patient is prescribed a new antipsychotic. What is a key safety monitoring parameter the consultant pharmacist should establish?
- Weekly lipid panels
- Monitoring for extrapyramidal symptoms, metabolic changes, and QTc prolongation (Correct answer)
- Daily serum drug levels
- Monthly echocardiograms
Correct answer: Monitoring for extrapyramidal symptoms, metabolic changes, and QTc prolongation
Antipsychotics carry risks of extrapyramidal effects, metabolic syndrome, and QTc prolongation that require structured ongoing monitoring.
