CSR Technology & Digital Tools 3 — Questions and Answers
Question 1: A renal dietitian uses continuous glucose monitoring (CGM) data for a diabetic dialysis patient. Which finding would most directly inform a dietary potassium intervention?
- Postprandial glucose spikes after high-fruit meals (Correct answer)
- Nocturnal hypoglycemia patterns
- Average sensor glucose of 180 mg/dL
- Time-in-range percentage below 70%
Correct answer: Postprandial glucose spikes after high-fruit meals
Postprandial spikes after high-fruit meals indicate fruit consumption, which also contributes significant dietary potassium in CKD patients.
Question 2: Which interoperability standard is most commonly used to enable dietary software to exchange data directly with hospital EHR systems?
- PDF document transfer
- HL7 FHIR (Fast Healthcare Interoperability Resources) (Correct answer)
- CSV file email attachment
- SNOMED CT code mapping alone
Correct answer: HL7 FHIR (Fast Healthcare Interoperability Resources)
HL7 FHIR is the current standard for real-time, structured electronic health data exchange between software systems including dietary tools and EHRs.
Question 3: A renal dietitian wants to objectively assess dietary sodium adherence between clinic visits. Which technology-based tool provides the most objective biochemical validation of sodium intake?
- A 24-hour dietary recall app completed by the patient
- 24-hour urine sodium measurement ordered and reviewed via patient portal (Correct answer)
- A smartwatch step-counter
- A blood pressure app logging home readings
Correct answer: 24-hour urine sodium measurement ordered and reviewed via patient portal
A 24-hour urine sodium is the gold standard objective measure of dietary sodium intake, and reviewing results through the patient portal integrates technology into monitoring.
Question 4: In a dialysis center deploying a digital patient education platform, which content format has the strongest evidence for improving dietary knowledge in low-health-literacy CKD patients?
- Dense text-based PDFs with clinical references
- Short video modules with visual demonstrations and plain language (Correct answer)
- Academic journal article summaries
- Interactive spreadsheets for self-calculation
Correct answer: Short video modules with visual demonstrations and plain language
Short videos with visual demonstrations are more effective than text-heavy materials for patients with low health literacy.
Question 5: When a renal dietitian uses predictive analytics embedded in an EHR to identify patients at high risk for hyperkalemia, which data input is most clinically meaningful for the algorithm?
- Patient age and gender only
- Combination of recent serum potassium trend, dietary intake records, and medication changes (Correct answer)
- Insurance type and appointment attendance
- Patient-reported pain scores
Correct answer: Combination of recent serum potassium trend, dietary intake records, and medication changes
Combining lab trends, dietary records, and medication changes provides a multifactorial input that best predicts hyperkalemia risk in CKD patients.
Question 6: Which approach best supports medication-nutrient interaction surveillance when a CKD patient is prescribed a new phosphate binder via an EHR system?
- Waiting for the patient to report side effects at the next visit
- Using EHR drug-nutrient interaction alerts integrated with the medication order entry system (Correct answer)
- Printing a static list of binder types for the patient
- Relying on the pharmacist alone without dietitian involvement
Correct answer: Using EHR drug-nutrient interaction alerts integrated with the medication order entry system
Integrated drug-nutrient interaction alerts in the medication ordering system enable real-time notification to the dietitian when clinically relevant prescriptions are entered.
Question 7: A renal dietitian is conducting a group telehealth education session for in-center hemodialysis patients on fluid restriction. Which platform feature is most important for engagement in this setting?
- Automatic session recording for compliance documentation
- Interactive polling and Q&A features to allow real-time patient participation (Correct answer)
- Virtual waiting room functionality
- Breakout room capability for small group splitting
Correct answer: Interactive polling and Q&A features to allow real-time patient participation
Interactive polling and Q&A keep patients engaged during group telehealth education and allow the dietitian to assess comprehension in real time.
