CCP Clinical Care in Long-Term Care 2 — Questions and Answers
Question 1: A 78-year-old LTC resident with stage 3 chronic kidney disease has an eGFR of 28 mL/min. Which antibiotic requires the most significant dose reduction for a urinary tract infection?
- Nitrofurantoin (Correct answer)
- Azithromycin
- Ciprofloxacin
- Doxycycline
Correct answer: Nitrofurantoin
Nitrofurantoin is contraindicated when eGFR <45 mL/min because it fails to achieve adequate urinary concentrations and can cause peripheral neuropathy due to drug accumulation.
Question 2: Which of the following is the MOST appropriate first-line pharmacological treatment for pain management in a non-verbal LTC resident with moderate osteoarthritis pain?
- Scheduled low-dose acetaminophen (Correct answer)
- Ibuprofen 400 mg TID
- Tramadol 50 mg PRN
- Morphine IR 5 mg PRN
Correct answer: Scheduled low-dose acetaminophen
Scheduled acetaminophen up to 3 g/day is the preferred first-line analgesic in older adults due to its favorable safety profile compared to NSAIDs and opioids.
Question 3: A consultant pharmacist reviews a resident's medication list and notes she is receiving both warfarin and fluconazole. What is the primary pharmacokinetic concern?
- Fluconazole induces CYP2C9, decreasing warfarin levels
- Fluconazole inhibits CYP2C9, increasing warfarin levels (Correct answer)
- Fluconazole displaces warfarin from albumin, lowering efficacy
- Fluconazole increases renal clearance of warfarin
Correct answer: Fluconazole inhibits CYP2C9, increasing warfarin levels
Fluconazole is a potent CYP2C9 inhibitor that dramatically reduces warfarin metabolism, leading to significantly elevated INR and bleeding risk.
Question 4: Under the CMS F-tag F758 regulations, which of the following constitutes an unnecessary antipsychotic use in a LTC setting?
- Antipsychotic for diagnosed schizophrenia with documented benefit
- Antipsychotic for behavioral symptoms of dementia without safety risk (Correct answer)
- Antipsychotic for Huntington's disease with documented benefit
- Antipsychotic for Tourette's syndrome with physician documentation
Correct answer: Antipsychotic for behavioral symptoms of dementia without safety risk
F758 prohibits antipsychotics for behavioral symptoms of dementia (wandering, repetitive behaviors) unless a specific diagnosis justifies use and non-pharmacological interventions have failed.
Question 5: A LTC resident with heart failure is started on carvedilol. The consultant pharmacist should monitor for which electrolyte disturbance that is especially common in heart failure patients on diuretics?
- Hypernatremia
- Hyperkalemia from carvedilol
- Hypokalemia from loop diuretics (Correct answer)
- Hypercalcemia from thiazides
Correct answer: Hypokalemia from loop diuretics
Loop diuretics commonly used in heart failure cause urinary potassium wasting, leading to hypokalemia, which can increase the risk of cardiac arrhythmias.
Question 6: Which clinical tool is MOST appropriate for systematic fall risk stratification in a newly admitted LTC resident?
- Mini-Mental State Examination (MMSE)
- Morse Fall Scale (Correct answer)
- CAGE questionnaire
- Braden Scale
Correct answer: Morse Fall Scale
The Morse Fall Scale is a validated, widely used instrument specifically designed to assess fall risk using six predictive factors in institutional settings.
Question 7: A consultant pharmacist identifies that a resident's bisphosphonate is being administered with the resident in a supine position due to limited mobility. What is the primary concern?
- Reduced absorption leading to treatment failure
- Esophageal irritation and risk of erosive esophagitis (Correct answer)
- Increased renal toxicity from prolonged contact
- CNS toxicity from systemic absorption
Correct answer: Esophageal irritation and risk of erosive esophagitis
Oral bisphosphonates require upright positioning for at least 30 minutes after administration to prevent esophageal irritation, erosion, and potentially esophageal ulcers.
