A patient requires enteral nutrition for approximately 3 weeks due to resolving dysphagia post-stroke. Which access route is most appropriate according to current ASPEN guidelines?
Show answer →Nasogastric (NG) tube is the gold standard for short-term access (<4 weeks). It is non-invasive, cost-effective, and allows for bolus, intermittent, or continuous feeding. Exam Tip: CDR emphasizes using the GI tract whenever possible and starting with the most physiological route. Nasoduodenal or nasojejunal is only preferred if gastric emptying is severely delayed or aspiration risk is extremely high. NG is the primary choice for standard short-term needs.
A malnourished patient with Stage 3 Heart Failure and AKI requires short-term PN. Why is PPN likely contraindicated despite the short duration?
Show answer →Fluid restriction requirements. PPN solutions are dilute (<900 mOsm/L), requiring large fluid volumes (often 2.5-3.5L/day) to provide adequate calories/protein. Patients with CHF or AKI cannot tolerate this volume. TPN allows for concentrated nutrients in a small volume (e.g., 1L), making it the safer choice for fluid-restricted patients regardless of duration.
When assessing a patient's tolerance to IDDSI Level 5 (Minced & Moist), which specific test ensures the food is moist enough to prevent sticking in the oropharynx?
Show answer →The Spoon Tilt Test. For Level 5, the food should be cohesive enough to hold its shape on the spoon, but when the spoon is tilted, the sample should slide off easily with very little food left on the spoon. It should not be sticky. This is critical for patients with poor tongue strength or pharyngeal residue. CDR Tip: If food sticks to the spoon, it fails the test and poses a choking risk.
A patient 2 months post-RYGB experiences diaphoresis, tachycardia, and abdominal cramping 20 minutes after eating a sweetened yogurt. What is the pathophysiological cause?
Show answer →Early Dumping Syndrome. This occurs when hyperosmolar chyme (high sugar/simple carbs) rapidly enters the small intestine, causing a rapid fluid shift from the intravascular space into the intestinal lumen. Treatment: Small, frequent meals; separate liquids from solids by 30-60 mins; avoid simple sugars. Exam Tip: Distinguish Early (osmotic/vasomotor symptoms 10-30m post-meal) from Late (reactive hypoglycemia 1-3h post-meal).
When conducting an internal audit of HACCP records, which four types of documentation are most critical for the CDR exam?
Show answer →1. Summary of the Hazard Analysis (rationale), 2. The written HACCP Plan (CCPs, limits, monitoring, and corrective actions), 3. Support documentation (validation studies, equipment calibration records, SOPs), 4. Daily Operational Records (monitoring logs, corrective action logs). CDR Exam Tip: If it wasn't documented, it didn't happen. Exam questions often ask which document proves a system is working; the answer is usually the Monitoring Log or Verification Audit.
