✍️ Sample RRT Questions & Answers
1. What does "IDDM" stand for in the context of diabetes?
IDDM stands for Insulin-Dependent Diabetes Mellitus, which is an older term for Type 1 Diabetes. This condition is characterized by the body's inability to produce insulin, a hormone necessary for glucose uptake by cells. Individuals with IDDM require daily insulin injections to manage their blood sugar levels.
2. Which type of patients might require continuous positive airway pressure (CPAP)?
CPAP is commonly used to treat sleep apnea by providing continuous airflow to keep the airway open.
3. Auto-PEEP (intrinsic PEEP) is MOST commonly caused by:
Auto-PEEP results from incomplete exhalation due to insufficient expiratory time, causing air trapping and dynamic hyperinflation.
4. A patient has the following ABG: pH 7.35, PaCO2 55 mmHg, HCO3 30 mEq/L. This result is MOST consistent with:
A near-normal pH with elevated PaCO2 and elevated HCO3 indicates chronic respiratory acidosis with full metabolic compensation (1 mEq/L HCO3 rise per 10 mmHg PaCO2 rise).
5. Which pulse oximetry reading is MOST likely to be falsely elevated (overestimated) in a patient with carbon monoxide poisoning?
Standard pulse oximetry cannot distinguish oxyhemoglobin from carboxyhemoglobin, so SpO2 reads falsely high in CO poisoning; co-oximetry is required for accurate measurement.
6. Which medication is used to treat methemoglobinemia in patients with toxic oxygen levels?
Methylene blue reduces methemoglobin back to functional hemoglobin by acting as an electron donor via the NADPH-dependent pathway.
